    This study examined whether high self-deceivers form their overly positive perception of their traits through overestimating their performance of self-presentation where they need to impress others as being extraverted/introverted, exhibiting more internalization of self-presentation (IOSP) of the trait. Participants were instructed to give either an extraverted or introverted impression through an oral (Study 1, N = 39) or written (Study 2, N = 62) self-presentation. Participants reported dispositional self-deception, self-presentation efficacy, and extraversion before and after self-presentation. Independent raters provided other-reported extraversion by examining the self-presentation. Across the two studies, two-way mixed ANOVA revealed that predicted change in extraversion occurred only for participants who made extraverted self-presentation. With the change in extraversion as an index of IOSP, mediation analyses revealed indirect effects of dispositional self-deception on IOSP via self-presentation efficacy but not other-reported extraversion. These results suggested that (a) people only internalize socially desirable traits like extraversion but not introversion, (b) writing to others is sufficient to cause IOSP, and (c) high self-deceivers internalize extraverted self-presentation not through actual performance but its subjective evaluation.

    Background: The comorbidity of depression and anxiety is associated with an increased risk of prolonged adverse mental health status. However, little is currently known about their genetic and environmental influences that help to explain both the comorbidity and distinctiveness. Using longitudinal twin data, the present study investigated both the overlapping and distinct relationships between depression and anxiety viewed from the perspective of Gray's Reinforcement Sensitivity Theory (RST): two personality traits of the Behavioral Inhibition and Activation Systems (BIS and BAS).Methods: A total of 422 twin pairs (298 monozygotic and 124 dizygotic pairs) participated by completing a personality questionnaire at wave 1, and mood symptoms questionnaires at wave 2. The waves were on average 2.23 years apart.Results: Multivariate Cholesky decomposition indicated that the genetic variance of the personality traits (BIS and BAS) explained all of the genetic variance in depressive and anxiety symptoms. Additionally, genetic factors related to the BIS positively explained depressive and anxiety symptoms, whereas genetic factors related to the BAS negatively explained only depressive symptoms. Limitations: Limitations include shorter time interval and the reliance on self-reported data.Conclusions: The present study provided evidence explaining the overlap and differentiation of depressive and anxiety symptoms by using data on personality traits in a longitudinal, genetically-informative design. The findings suggested the personality traits from Gray's RST model played an important role in the prediction, and clarified the description, of both depressive and anxiety symptoms.

    Using a genetically informative design (about 2000 twin pairs), we investigated the phenotypic and genetic and environmental architecture of a broad construct of conscientiousness (including conscientiousness per se, effortful control, self-control, and grit). These four different measures were substantially correlated; the coefficients ranged from 0.74 (0.72-0.76) to 0.79 (0.76-0.80). Univariate genetic analyses revealed that individual differences in conscientiousness measures were moderately attributable to additive genetic factors, to an extent ranging from 62 (58-65) to 64% (61-67%); we obtained no evidence that shared environmental influences were observed. Multivariate genetic analyses showed that for the four measures used to assess conscientiousness, genetic correlations were stronger than the corresponding non-shared environmental correlations, and that a latent common factor accounted for over 84% of the genetic variance. Our findings suggest that individual differences in the four measures of conscientiousness are not distinguishable at both the phenotypic and behavioural genetic levels, and that the overlap was substantially attributable to genetic factors.

    Background The phenotypic and aetiological architecture of depression symptomatology has been mostly studied in Western samples. In this study, we conducted a genetically informed factor analysis to elucidate both the phenotypic and aetiological architectures of self-reported depression among a Japanese adult twin sample. Methods Depressive symptoms assessed by Zung's Self-rating Depression Scale were self-rated by 425 twin pairs (301 monozygotic and 124 dizygotic twin pairs) in a community sample in Japan. Results An exploratory factor analysis extracted three symptom domains representing cognitive, affective and somatic symptomatology. A confirmatory factor analysis demonstrated that a bi-factor solution fitted better than the alternative solutions, implying that depression may be defined as a combination of a single general construct and three factors specific to each of the three symptom domains. A multivariate genetic analysis with the bi-factor solution showed that the general factor was substantially heritable (47%), and that only the affective symptom domain was significantly heritable (29%) among the three specific factors, their remaining variance being explained by non-shared environmental influences. Conclusions Depression symptomatology appears to be adequately captured by a substantially heritable general factor. The heritability of this factor (47%) in a Japanese adult sample is in line with commonly reported heritability estimates for depression. The three specific factors - cognitive, affective and somatic - are mostly explained by non-shared environmental factors, which include measurement error. The extent to which these specific factors are uniquely associated with correlates of depression when the general factor is accounted for should be investigated in future studies.

  7. MODERATING EFFECTS OF RELIGIOSITY IN THE GENETIC AND ENVIRONMENTAL ETIOLOGY OF THE BIG FIVE PERSONALITY TRAITS IN ADULTHOOD Reviewed International journal

    This study examined whether religiosity moderates the genetic and environmental etiology of the Big Five personality traits (Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness). Data from a nationwide sample of 549 twin pairs collected through the MacArthur Foundation National Survey of Midlife Development in the United States were analyzed. Analyses of a gene-environment interaction model revealed that religiosity moderated the magnitude of genetic and environmental influences on Agreeableness and Conscientiousness; for those who were religious, environmental influences on Agreeableness and genetic influences on Conscientiousness were greater. Religiosity exhibited weak main effects on both traits, with higher religiosity contributing to higher levels of both traits. These results suggested that religiosity serves as a psychological immune system that restricts individuals' levels of Agreeableness and Conscientiousness within a religiously appropriate range, insulating them from internal and external forces. Implications for personality theory and molecular genetic research on personality and psychopathology are discussed.

    This study used a behavioral genetic approach to examine the genetic and environmental etiology of stability and changes in self-esteem in relation to personality. Multiple genetic analyses were conducted on a longitudinal dataset of self-esteem and Big Five personality scores among young adult Japanese twins over the course of a decade. There were 1221 individuals'for whom data were available on both self-esteem and the Big Five personality test at Time 1 and 365 at Time 2. The mean interval between the two times was 9.95 years. Genetic effects on self-esteem were robust, and the same genes were responsible for the stability of self-esteem in individuals over time. Nearly half of the variance in self-esteem was explained by a new genetic factor arising during the decade, suggesting that genetic innovation of self-esteem occurred in early adult life. The genetic and environmental covariance structure between personality and self-esteem in individuals was constant over a decade, providing evidence that the stability of self-esteem was largely attributable to personality. However, genetics for self-esteem independent of personality still contributed to stability over time, differentiating

    The objective of this article is to measure the causal effect of education on earnings using a large dataset of twins compiled in Japan with wide-ranging socioeconomic information. Recent research conducted in China showed that, contrary to the case in Western countries, ability bias is large in estimating the return to education. It is argued that the low rate of return in China is in part due to the competitive and exam-oriented education system, which is similar to the system in Japan. The empirical results in our study show that the estimated rate of return to education using the sample of identical twins in Japan is 9.3 percent even after omitted ability bias and measurement errors in self-reported schooling were corrected. Our findings suggest that the conventional OLS estimate is not significantly contaminated by potential biases in Japan.

    The present study examined: (1) gender and age differences of mean gender identity disorder (GID) trait scores in Japanese twins; (2) the validity of the prenatal hormone transfer theory, which predicts that, in dizygotic (DZ) twin pairs, twins with an opposite-gender co-twin more frequently exhibit GID traits than twins with a same-gender co-twin; and (3) the magnitude of genetic and environmental influences on GID traits as a function of age and gender. Data from 1450 male twin pairs, 1882 female twin pairs, and 1022 DZ male-female pairs ranging from 3 to 26 years of age were analyzed. To quantify individual variances in GID traits, each participant completed four questionnaire items based on criteria for GID from the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR). Our most important findings were: (1) Japanese females exhibited GID traits more frequently than males and Japanese children exhibited GID traits less frequently than adolescents and adults (among females, the prevalence was 1.6 % in children, 10 % in adolescents, and 12 % in adults; among males, the prevalence was 0.5, 2, and 3 %, respectively); (2) the data did not support the prenatal hormone transfer theory for GID traits; and (3) a large part of the variance for GID traits in children was accounted for by familial factors; however, the magnitude was found to be greater in children than in adolescents or adults, particularly among females. This study suggests that although the prevalence is likely to increase, familial effects are likely to decrease as individuals age.

    This study developed Multi-Dimensional Active Learner Scale and examined its reliability and validity. Forty five items were developed in reference to the aims of KlKAN Education in Kyushu University. A questionnaire survey was completed by 353 undergraduate students. Results of exploratory factor analyses on the 45 items suggested six-factor solution, and 20 items were selected to achieve both ease of administration and reasonable reliability. The resultant scale consisted of six subscales: inquisitiveness, collaborative learning skills, striving to achievement, critical thinking, logical thinking, and perspective on university life. Confirmatory factor analysis on 20 items showed adequate fit. The overall scale and six subscales showed reasonable internal consistency (Cronbach's a = .86 for the overall scale, a = .62-.78 for the subscales). Correlations with self-directed learning, experience on group learning, and Big Five personality items suggested construct validity of the scale.

    Why does decision making differ among individuals? People sometimes make seemingly inconsistent decisions with lower expected (monetary) utility even when objective information of probabilities and reward are provided. It is noteworthy, however, that a certain proportion of people do not provide anomalous responses, choosing the alternatives with higher expected utility, thus appearing to be more "rational." We investigated the genetic and environmental influences on these types of individual differences in decision making using a classical Allais problem task. Participants were 1,199 Japanese adult twins aged 20-47. Univariate genetic analysis revealed that approximately a third of the Allais problem response variance was explained by genetic factors and the rest by environmental factors unique to individuals and measurement error. The environmental factor shared between families did not contribute to the variance. Subsequent multivariate genetic analysis clarified that decision making using the expected utility theory was associated with general intelligence and that the association was largely mediated by the same genetic factor. We approach the mechanism underlying two types of "rational" decision making from the perspective of genetic correlations with cognitive abilities.

    Little is known about why people differ in their levels of academic motivation. This study explored the etiology of individual differences in enjoyment and self-perceived ability for several school subjects in nearly 13,000 twins aged 9-16 from 6 countries. The results showed a striking consistency across ages, school subjects, and cultures. Contrary to common belief, enjoyment of learning and children's perceptions of their competence were no less heritable than cognitive ability. Genetic factors explained approximately 40% of the variance and all of the observed twins' similarity in academic motivation. Shared environmental factors, such as home or classroom, did not contribute to the twin's similarity in academic motivation. Environmental influences stemmed entirely from individual specific experiences. (C) 2015 Published by Elsevier Ltd.

    Prosociality is one of the most distinctive features of human beings but there are individual differences in cooperative behavior. Employing the twin method, we examined the heritability of cooperativeness and its outcomes on public goods games using a strategy method. In two experiments (Study 1 and Study 2), twin participants were asked to indicate (1) how much they would contribute to a group when they did not know how much the other group members were contributing, and (2) how much they would contribute if they knew the contributions of others. Overall, the heritability estimates were relatively small for each type of decision, but heritability was greater when participants knew that the others had made larger contributions. Using registered decisions in Study 2, we conducted seven Monte Carlo simulations to examine genetic and environmental influences on the expected game payoffs. For the simulated one-shot game, the heritability estimates were small, comparable to those of game decisions. For the simulated iterated games, we found that the genetic influences first decreased, then increased as the numbers of iterations grew. The implication for the evolution of individual differences in prosociality is discussed.

    This study examined how the personality traits of behavioral inhibition and behavioral activation contribute to the development of anxiety and depression. We used two-wave short-term longitudinal data from 319 students. Data collections were two months apart. Personality traits were assessed using Gray's Reinforcement Sensitivity Theory: Behavioral Inhibition and Activation Systems (BIS and BAS). After confirming simple correlations, hierarchical regressions were conducted to test how residual changes or unique variances in psychopathology were predicted by the personality traits. Findings revealed that high BIS sensitivity predicted both anxiety and depression, while low BAS sensitivity predicted only depression. These results suggest that hyperactive BIS functions as a predictor for general distress, and that hypoactive BAS functions as a unique predictor for depression.

    A cultural behavior genetic approach was introduced as a prospective means to describe psychological differences between cultures. We compared genetic and environmental influences on remembered parenting for samples of twins from Japan and Sweden. Data were collected from 720 pairs of young adult Japanese twins and 824 pairs of adult Swedish twins using the Parental Bonding Instrument. In both samples, a very similar phenotypic factor structure was developed for maternal and paternal parenting. However, the genetic and environmental contributions were different. Parenting in Japan showed more genetic influences, whereas parenting in Sweden showed more shared environmental influences. Moreover, covariation among the six dimensions of parenting (i.e., maternal and paternal Warmth, Protectiveness, and Authoritarianism) was due to genetic correlations in Japan and to shared environmental correlations in Sweden. These results are consistent with the cultural psychology argument that parenting practices are child centered in Japan but parent centered in the West.

    The Keio Twin Research Center has conducted two longitudinal twin cohort projects and has collected three independent and anonymous twin data sets for studies of phenotypes related to psychological, socioeconomic, and mental health factors. The Keio Twin Study has examined adolescent and adult cohorts, with a total of over 2,400 pairs of twins and their parents. DNA samples are available for approximately 600 of these twin pairs. The Tokyo Twin Cohort Project has followed a total of 1,600 twin pairs from infancy to early childhood. The large-scale cross-sectional twin study (CROSS) has collected data from over 4,000 twin pairs, from 3 to 26 years of age, and from two high school twin cohorts containing a total of 1,000 pairs of twins. These data sets of anonymous twin studies have mainly targeted academic performance, attitude, and social environment. The present article introduces the research designs and major findings of our center, such as genetic structures of cognitive abilities, personality traits, and academic performances, developmental effects of genes and environment on attitude, socio-cognitive ability and parenting, genes x environment interaction on attitude and conduct problem, and statistical methodological challenges and so on. We discuss the challenges in conducting twin research in Japan.

    This twin study examined the bidirectional relationship between maternal parenting behaviors and children's peer problems that were not confounded by genetic and family environmental factors. Mothers of 259 monozygotic twin pairs reported parenting behaviors and peer problems when twins were 42 and 48 months. Path analyses on monozygotic twin difference scores revealed that authoritative parenting (the presence of consistent discipline and lack of harsh parenting) and peer problems simultaneously influenced each other. Authoritative parenting reduced peer problems, and peer problems increased authoritative parenting. Neither consistent discipline nor harsh parenting alone was associated with peer problems. These results suggest that maternal authoritative parenting works protectively in regard to children's peer problems, and peer problems can evoke such effective parenting. © 2012 Blackwell Publishing Ltd.

    This study investigated the association between negative parenting (NP) and conduct problems (CP) in 6-year-old twins, taking into account the severity of hyperactivity/inattention problems (HIAP). Analyses of the data from 1,677 pairs of twins and their parents revealed that the shared environmental covariance between NP and CP was moderated by the level of HIAP but not by CP or NP, where the shared environmental covariance was larger in children with higher levels of HIAP than in children with lower levels of HIAP. The genetic covariance between NP and CP was not moderated by the level of HIAP, whereas it was larger in the group with lower levels of CP and NP than in the group with higher levels. These results suggest that severe HIAP strengthens shared environmental associations between NP and CP and that interventions focusing on the shared environmental component of NP would be effective for parents and children with severe HIAP.

    Although growth in head circumference (HC) during infancy is known to predict later childhood outcomes, the mechanisms underlying this association with later sociocognitive abilities remain undetermined. Thus, using a sample of 241 pairs of normally developing Japanese twins, this study investigated the underpinnings of the association between HC growth (difference between HC at birth and at 10 months) and sociocognitive abilities at 19 months as measured by 10 items from the M-CHAT. Phenotypic correlations between HC at birth and sociocognitive abilities and between HC growth and sociocognitive abilities were marginal and not significant. However, multivariate genetic analyses using Cholesky decomposition revealed that genetic influences on HC growth and those on sociocognitive abilities were negatively associated. On the other hand, shared and nonshared environmental influences on HC growth were positively associated with influences on sociocognitive abilities. Genetic and environmental influences on HC at birth were not significantly associated with influences on sociocognitive abilities. These results help to clarify the role of brain growth during infancy in the subsequent development of sociocognitive abilities and highlight the importance of examining the different roles of genetic and environmental influences in studies of these areas.

    Direction of causation between the Gray's Behavioral Inhibition System (BIS), depression, and anxiety was investigated. Data of 424 twin pairs were subjected to direction of causation modeling, which is a method for inferring causal relationship from cross-sectional family data. Four causal models were examined: (1) BIS influences depression/anxiety, (2) depression/anxiety influences BIS, (3) they have mutual causal relationship, and (4) correlations between them are caused by a third variable, such as latent genetic and environmental factors. Results indicated that Model 1, which assumes BIS to have a causal influence, well fitted both depression and anxiety. When influences from BIS were considered, direction of causation modeling revealed that depression and anxiety have positive causal influences on each other. These results support the view that BIS is a diathesis for psychopathology. Results also suggest that interventions aimed at either depression or anxiety may improve the other mood state.

    The authors examined data (N = 34,108) on the differential reliability and validity of facet scales from the NEO Inventories. They evaluated the extent to which (a) psychometric properties of facet scales are generalizable across ages, cultures, and methods of measurement, and, (b) validity criteria are associated with different forms of reliability. Composite estimates of facet scale stability, heritability, and cross-observer validity were broadly generalizable. Two estimates of retest reliability were independent predictors of the three validity criteria; none of three estimates of internal consistency was. Available evidence suggests the same pattern of results for other personality inventories. Internal consistency of scales can be useful as a check on data quality but appears to be of limited utility for evaluating the potential validity of developed scales, and it should not be used as a substitute for retest reliability. Further research on the nature and determinants of retest reliability is needed.

    In the literature on achievement goals, performance-approach goals (striving to do better than others) and performance-avoidance goals (striving to avoid doing worse than others) tend to exhibit a moderate to high correlation, raising questions about whether the 2 goals represent distinct constructs. In the current article, we sought to examine the separability of these 2 goals using a broad factor-analytic approach that attended to issues that have been overlooked or underexamined in prior research. Five studies provided strong evidence for the separation of these 2 goal constructs: Separation was observed not only with exploratory factor analysis across different age groups and countries (Studies 1a and 1b) but also with change analysis (Study 2), ipsative factor analysis (Study 3), within-person analysis (Study 4), and behavioral genetics analysis (Study 5). We conclude by discussing the implications of the present research for the achievement goal literature, as well as the psychological literature in general.

    It has been reported that the ability to solve syllogisms is highly g-loaded. In the present study, using a self-administered shortened version of a syllogism-solving test, the BAROCO Short, we examined whether robust findings generated by previous research regarding IQ scores were also applicable to BAROCO Short scores. Five syllogism-solving problems were included in a questionnaire as part of a postal survey conducted by the Keio Twin Research Center. Data were collected from 487 pairs of twins (1021 individuals) who were Japanese junior high or high school students (ages 13-18) and from 536 mothers and 431 fathers. Four findings related to IQ were replicated: 1) The mean level increased gradually during adolescence, stayed unchanged from the 30s to the early 50s, and subsequently declined after the late 50s. 2) The scores for both children and parents were predicted by the socioeconomic status of the family. 3) The genetic effect increased, although the shared environmental effect decreased during progression from adolescence to adulthood. 4) Children's scores were genetically correlated with school achievement. These findings further substantiate the close association between syllogistic reasoning ability and g. (C) 2011 Elsevier Inc. All rights reserved.

    Factors contributing to individual differences of empathy were examined using behavioral genetics methodology. Data related to individual levels of empathy and parental warmth received during childhood were collected from approximately 450 pairs of twins (ages 14-33). A bivariate model analysis clarified that shared family environmental factors did not contribute to the formation of empathy. No common shared environmental factors were detected between empathy and parental warmth, either. The positive correlation between the two variables was mediated principally by genetics. The result does not support socialization theory, which holds that warm parenting nurtures children's empathy. However, the subsequent gene-environment interaction model analysis revealed that shared family environmental factors significantly affected the formation of empathy for those with high or very low parental warmth. The results imply that individuals with a strong or very weak attachment to their parents were more influenced by the shared family environment.

    The present research examined the relationship between heritability and response time for the Big Five personality facets in three samples of adults and adolescents. We predicted that the larger the heritability of a facet the faster is the response to the items of that facet. In support of our predictions, the results showed that heritability and response time were indeed negatively correlated. The effect size of the relationship was small but systematic and statistically significant across all samples. The findings underline the generality of personality heritability and highlight the link between heritability and behavioral indicators. The potential usefulness of both heritability estimates and response time in research on personality is discussed.

    This study investigated the possible effects of genetic and environmental gender differences in effect on individual differences by using the Bem Sex Role Inventory (BSRI) with twins. A sex/gender-limitation analysis, a behavior genetics methodology was used to the following: (a) effects of gender-specific genes, (b) gender differences in quantitative genetic effects, (c) effects of gender-specific shared environment, (d) gender differences of quantitative shared environment, and (e) gender differences of quantitative nonshared environment. Participants were adolescent and adult twins, including 111 identical male pairs, 241 identical female pairs, 36 fraternal male pairs, 65 fraternal female pairs, and 58 opposite-gender pairs. The results indicated that although masculinity and femininity were explained by genetic factors to some extent, there were no significant gender differences in the genetic factors. Moreover, because our data did not support a model which explained gender differences in the effects of specific common environment factors, no evidence was found to support the prenatal hormonal hypothesis or the existence of parenting which encouraged children's gender role personality.

    J. M. Digman (1997) proposed that the Big Five personality traits showed a higher-order structure with 2 factors he labeled alpha and beta. These factors have been alternatively interpreted as heritable components of personality or as artifacts of evaluative bias. Using structural equation modeling, the authors reanalyzed data from a cross-national twin study and from American cross-observer studies and analyzed new multimethod data from a German twin study. In all analyses, artifact models outperformed substance models by root-mean-square error of approximation criteria, but models combining both artifact and substance were slightly better. These findings suggest that the search for the biological basis of personality traits may be more profitably focused on the 5 factors themselves and their specific facets, especially in monomethod studies.

    Since natural selection produces genetically homogeneous populations with regard to adaptively important traits, the relatively high genetic variance associated with human personality is an enigma. In this article, we propose that humans adaptively control the activation of domain-specific mental mechanisms in accordance with personality. This process functions to reduce fitness differences among individuals with different genetic backgrounds associated with personality. Such control would facilitate the evolution of heritable personality traits. We conducted a twin study, showing that the level of general trust (trust of strangers) is controlled not only by environmental factors but also by personality factors, thus producing reactive heritability of general trust. This result supports our hypothesis. (c) 2008 Elsevier Inc. All rights reserved.

         With the use of behavioral genetics methodology, in which variance of an observed trait can be decomposed into the effect of three latent variables, that is, genetic, shared environmental, and nonshared environmental, factors contributing to the formation of authoritarian conservatism were examined. 4111 participants (1279 male twins and 1899 female twins between the ages of 12-26, as well as 83 fathers and 860 mothers of the twins) responded to the Authoritarian Conservatism Scale. The twin model analysis employing 912 pairs of identical and 630 pairs of fraternal twins accounted for 33% of the variance of authoritarian conservatism by genetics, and 67% by nonshared environment. The subsequent twin parent-offspring model analysis also produced a very similar result. Thus, it was revealed that what mediated the familial transmission of authoritarian conservatism was genetics, not cultural transmission. Theories explaining the formation of authoritarianism by parenting or social background of the family are not supported. Transmission models can be further elaborated by including genetics as a predictable variable.

    Although there is a great deal of interest in the Behavioral Inhibition System (BIS) and Behavioral Activation System (BAS) - two temperaments formulated by Gray's reinforcement sensitivity theory-few studies have examined the genetic and environmental etiology underlying their continuity and change. Using a two-wave longitudinal data set of twins from late adolescence to early adulthood, this study examined (1) whether genetic influences contribute to change as well as continuity of the two temperaments and (2) whether the magnitude of genetic influences on the BIS and BAS differs across the two measurement points. The questionnaire was administered to 448 twin pairs at two waves, with an interval of approximately 2-3 years. Univariate genetic analyses revealed that genetic factors accounted for around one-third of the phenotypic variance in the BIS and BAS traits at both waves. Longitudinal bivariate analyses revealed that (1) genetic influences contribute only to continuity, whereas environmental influences contribute to both continuity and change in the two traits, and (2) the degree of genetic influences does not differ. across time. These results suggest that in this age period, temporal stability of individual differences in the BIS and BAS owes more to genetic than to environmental factors. (C) 2007 Elsevier Ltd.

    This article introduced methodology of human behavior genetics and twin study, especially multivariate genetic analysis, which was then applied to examine association between temperament and problem behaviors among children aged four to six years old. A questionnaire was mailed to 142 mothers of twins to obtain mother ratings of children's Effortful Control (EC), externalizing problems (EP), and internalizing problems (IP). Analysis of phenotypic correlations revealed that EP and IP had a positive correlation that was moderate (<i>r</i>=.55), and EC had a negative correlation with both EP (<i>r</i>=−.42) and IP (<i>r</i>=−.18). Multivariate genetic analysis revealed that the genetic influence that decreased EC also worked to increase both EP and IP, suggesting low EC may be a common genetic diathesis of EP and IP. Phenotypic correlation between EP and IP was explained by genetic (22.8%), shared environmental (53.4%), and non-shared environmental influence (23.8%). However, relatively low genetic contribution to the phenotypic correlation may be explained in terms of two counteracting influences: genetic influence on EC, which makes the correlation positive, and genetic influence unrelated to EC, which makes the correlation negative.

    There is empirical evidence that underlying the Big Five personality factors are two higher-order factors which have come to be known as "alpha" (a) and "beta" (beta). The alpha factor is defined by the agreeableness, conscientiousness, and emotional stability domains; whereas beta is delineated by extraversion and intellect. It has been argued that a and beta are important constructs because they bridge the gap between psychometric studies of personality and theories of personality development. However, it is unclear if alpha and beta are constructs that can be reliably reproduced across a diverse range of independent samples. In a sample of 1209 MZ and 701 DZ twin pairs from Canada, Germany, and Japan who completed the NEO-PI-R, factorial analyses of the five NEO-PI-R domains extracted two factors resembling alpha and beta. Subsequent multivariate genetic analyses revealed that this factor structure was a clear reflection of the organizing effects of multiple genetic influences, providing evidence for alpha and beta as stable heuristic devices that can be used to integrate personality measurement and developmental theory.

Factor analyses were conducted on matrices of phenotypic, genetic, and environmental correlations estimated in a sample of 1,209 monozygotic and 701 dizygotic twin pairs from Canada, Germany, and Japan. Five genetic and environmental factors were extracted for each sample. High congruence coefficients were observed when phenotypic, genetic, and environmental factors were compared in each sample as well as when each factor was compared across samples. These results suggest that the FFM has a solid biological basis and may represent a common heritage of the human species.

    This study developed Japanese version of Effortful Control (EC) scale for adults, and examined its reliability and validity. In Study 1, a questionnaire survey of 209 college and vocational school students showed sufficient internal consistency and test-retest reliability for the scale. Its correlational validity was also shown in terms of the relationships with novelty seeking, harm avoidance, Five-Factor personality dimensions, depressive mood, and state anxiety. Study 2 was conducted to show that the EC scale measured not only self-concept but also actual executive attention function. Fo...

    Individual temperamental factors that contribute to the development of two perfectionism traits were studied in 428 Japanese undergraduate students using the Multidimensional Perfectionism Scale (MPS) and Temperament and Character Inventory (TCI). The results showed that self-oriented perfectionism is associated with the temperamental characteristics of low novelty seeking, high reward dependence, and high persistence. In contrast, socially prescribed perfectionism is associated with low novelty seeking and high harm avoidance. Hierarchical regression analysis revealed that these temperaments primarily predicted self-oriented perfectionism, controlling for socially prescribed perfectionism. These temperamental characteristics did not predict socially prescribed perfectionism when self-oriented perfectionism was controlled. (C) 2004 Elsevier Ltd. All rights reserved.

    The multivariate genetic and environmental structure of Cloninger's Temperament and Character Inventory (TCI) was investigated in a sample of 617 pairs of adolescent and young adult twins from Japan. Additive genetic factors accounted for 22% to 49% of the variability on all TCI temperament scales. Although the theory predicts lower heritability for the character scales, all character subscales had a substantial genetic contribution, and nonshared environmental influences accounted for the remainder. Multivariate genetic analyses showed that several subscales used to define one dimension shared a common genetic basis with subscales defining others. Using the degree of shared genetic influence as the basis to rearrange the TCI subscales into new dimensions, it was possible to create genetically independent scales. The implications for personality measurement, theory, and molecular genetic research are discussed.

    This study examined how the personality traits of behavioral inhibition and behavioral activation contribute to the development of anxiety and depression. We used two-wave short-term longitudinal data from 319 students. Data collections were two months apart. Personality traits were assessed using Gray's Reinforcement Sensitivity Theory: Behavioral Inhibition and Activation Systems (BIS and BAS). After conirming simple correlations, hierarchical regressions were conducted to test how residual changes or unique variances in psychopathology were predicted by the personality traits. Findings revealed that high BIS sensitivity predicted both anxiety and depression, while low BAS sensitivity predicted only depression. These results suggest that hyperactive BIS functions as a predictor for general distress, and that hypoactive BAS functions as a unique predictor for depression.

    Language:Japanese  

    Factors contributing to individual differences of empathy were examined using behavioral genetics methodology. Data related to individual levels of empathy and parental warmth received during childhood were collected from approximately 450 pairs of twins (ages 14-33). A bivariate model analysis clarified that shared family environmental factors did not contribute to the formation of empathy. No common shared environmental factors were detected between empathy and parental warmth, either. The positive correlation between the two variables was mediated principally by genetics. The result does not support socialization theory, which holds that warm parenting nurtures children's empathy. However, the subsequent gene-environment interaction model analysis revealed that shared family environmental factors significantly affected the formation of empathy for those with high or very low parental warmth. The results imply that individuals with a strong or very weak attachment to their parents were more influenced by the shared family environment.

    © Springer Science+Business Media, LLC 2009. All rights reserved. Gordon Allport (1937) has penned some of the most influential lines in the history of personality research. He defined personality as the dynamic organization within the individual of those psychophysical systems that determine his unique [sic] adjustments to this environment (p. 48) and that personality is something and personality does something (p. 48). Together, these lines neatly summarize the primary mission of personality research: (1) the characterization of enduring qualities that give rise to regularities and consistencies in behaviour and the organization of these qualities and (2) how they achieve coherent functioning to actively adapt to the social environment (Livesley & Jang, 2005). As a result, much of mainstream personality research has been directed towards determining the number of basic traits, their organization, how they can be measured reliably, and the relationship between normal personality function and personality disorder.

     More details

    With the use of behavioral genetics methodology, in which variance of an observed trait can be decomposed into the effect of three latent variables, that is, genetic, shared environmental, and nonshared environmental, factors contributing to the formation of authoritarian conservatism were examined. 4111 participants (1279 male twins and 1899 female twins between the ages of 12-26, as well as 83 fathers and 860 mothers of the twins) responded to the Authoritarian Conservatism Scale. The twin model analysis employing 912 pairs of identical and 630 pairs of fraternal twins accounted for 33% of the variance of authoritarian conservatism by genetics, and 67% by nonshared environment. The subsequent twin parentoffspring model analysis also produced a very similar result. Thus, it was revealed that what mediated the familial transmission of authoritarian conservatism was genetics, not cultural transmission. Theories explaining the formation of authoritarianism by parenting or social background of the family are not supported. Transmission models can be further elaborated by including genetics as a predictable variable.

     More details

    There is empirical evidence that underlying the Big Five personality factors are two higher-order factors which have come to be known as "alpha" (α) and "beta" (β). The α factor is defined by the agreeableness, conscientiousness, and emotional stability domains; whereas β is delineated by extraversion and intellect. It has been argued that α and β are important constructs because they bridge the gap between psychometric studies of personality and theories of personality development. However, it is unclear if α and β are constructs that can be reliably reproduced across a diverse range of independent samples. In a sample of 1209 MZ and 701 DZ twin pairs from Canada, Germany, and Japan who completed the NEO-PI-R, factorial analyses of the five NEO-PI-R domains extracted two factors resembling α and β. Subsequent multivariate genetic analyses revealed that this factor structure was a clear reflection of the organizing effects of multiple genetic influences, providing evidence for α and β as stable heuristic devices that can be used to integrate personality measurement and developmental theory. © 2006 Elsevier Ltd.

    The multivariate genetic and environmental structure of Cloninger's Temperament and Character Inventory (TCI) was investigated in a sample of 617 pairs of adolescent and young adult twins from Japan. Additive genetic factors accounted for 22% to 49% of the variability on all TCI temperament scales. Although the theory predicts lower heritability for the character scales, all character subscales had a substantial genetic contribution, and nonshared environmental influences accounted for the remainder. Multivariate genetic analyses showed that several subscales used to define one dimension shared a common genetic basis with subscales defining others. Using the degree of shared genetic influence as the basis to rearrange the TCI subscales into new dimensions, it was possible to create genetically independent scales. The implications for personality measurement, theory, and molecular genetic research are discussed.

    青年期のうつ症状の発現のあり方は,前後の発達段階と様相が異なる。その背景として,認知的能力の複雑な発達,衝動制御困難,社会的刺激による被影響性の不均衡に由来する,青年期独自の感情制御の脆弱性が挙げられる。しかし青年期のうつ症状における感情制御と社会的環境の相互作用的影響は,未だ検討が少ない。
    そこで本研究では,青年期における,第二次性徴,認知能力,社会的関係と,感情制御の発達の関連およびうつ症状へ及ぼす影響について検討する。本研究では特別研究員奨励費助成の対象である三コホートを追跡,計五時点の縦断的研究を行い,後期児童期から青年期を通した,早期成人期への繋がりの網羅的な検討を行う。
    青年期のうつ症状の発現のあり方は,前後の発達段階と様相が異なるため,青年期はその後の適応において重要な時期とされている。青年期における精神病理への脆弱性は,認知的能力の複雑な発達,衝動制御困難,社会的刺激による被影響性の不均衡に由来する,青年期独自の感情制御の脆弱性に起因すると考えられている。しかし青年期のうつ症状における感情制御と社会的環境の縦断的影響は,未だ検討が少ない。
    そこで本研究では,青年期における,第二次性徴,認知能力,社会的関係と,感情制御の発達の関連およびうつ症状へ及ぼす相互作用的影響について,縦断研究により検討する。本研究では特別研究員奨励費助成の対象であった三コホートを追跡,計五時点の縦断的研究を行い,後期児童期から青年期を通した,早期成人期への繋がりの網羅的な検討を行う。(なお本研究費では,特別研究員奨励費助成で郵送できなかった者を対象とすること,および特別研究員奨励費助成の終了後の追跡を行うことから,研究費の競合は起こらないことを申し添える)
    令和2年度は,以下について実施した。1. 質問紙本調査 (2回目; 特別研究員奨励費助成から換算して4回目) を郵送にて実施し,132家庭からの回答を得,データクリーニングを終了した。2. 青年期の親からの感情の社会化尺度日本語版の信頼性および妥当性に関する英語論文を執筆し,査読中である。3. 環境感受性と第二次性徴がうつ症状へ及ぼす影響に関する英語論文を執筆し,査読中である。
    4. 感情制御の発達と適応に関する一連の成果について,令和2年9-11月に日本心理学会にてポスター発表を行った。
    5. 青年期の友人からの感情の社会化尺度日本語版の因子構造と予測的妥当性について,令和3年3月に日本発達心理学会にてポスター発表を行った。またこれについて,英語論文を執筆し,投稿準備中である。
    本年度計画していた質問紙郵送調査を実施することができた。尺度の精度を検討するための調査結果について学会発表および英語論文の執筆,縦断データの成果についての学会発表および英語論文の執筆もできた点で,おおむね順調に進展していると考える。引き続き,これまでに得られたデータについて,研究業績としてまとめることができるよう努めている。

    There is a social demand for critical thinking education in the modern information society, but there are problems such as a lack of teaching materials, inconsistencies in evaluation standards, and a lack of instructors. In this study, we developed a prototype application "C-training," an active learning-type teaching material that allows learners to train themselves in critical thinking without an instructor, and verified its educational effects.
    We conducted comparative experiments on the following points: (1) whether an educational method using active learning methods can work effectively, (2) whether the interface of the web application is effective as a teaching material, and (3) whether the learning effect can be enhanced by incorporating gamification elements.

    論証の論理構成を評価する能力は、現代社会にあふれる様々な言説を良き市民として適切に考慮し、自他の主張の根拠・前提を客観的に把握し、生産的なコミュニケーションを可能にするための必須のスキル(知的インフラ)であり、特に高等教育が涵養すべき能力として極めて重要である。本研究は、論証を扱う能力の個人差(=論証リテラシー)について定量的に測定し、その教育手法について検討を行ったものである。
    文献レビュー、研究協力者とのディスカッションに基づき、反論の要素を含めた双方向的論証に関するリテラシーを測定するテスト項目の開発を行った。調査データに基づき、反論の要素を含めた論証リテラシーの測定に関する課題を明らかにするとともに、議論への開かれた態度・指向性を測定することの重要性を明らかにした。
    また、初年次における議論教育の効果について、無作為配置を伴うフィールド実験による検討を行った。とりわけ「構造的討論」と呼ばれる手法について、その論証リテラシーおよび議論への指向性に与える教育効果を検討した。
    最終年度は、ウェブ調査の実施により論証リテラシーを測定するテストの改善を計画していたが、年度初頭に生じた研究代表者の健康上の理由により研究の実施が困難となったため、やむなく研究課題を廃止とし、年度初頭に購入した少額物品以外研究費の支出を行わなかった。今後、最終年度以前に得られたデータを基にした研究発表により、研究成果を学界・社会に還元していく予定である。

    Two longitudinal twin studies, for childhood and adulthood, were conducted.
    In the children cohort, about 200 pairs of fifth graders(11yrs) answered the questionnaire asking academic abilities, social adaptability and educational environments. 120 pairs were given individual develpmental survey for executive functions and so on. Genetic and environmental stability and changes were found in those traits and rythmic tempo showed an interesting GxE interaction.
    In the adulthood cohort, about 200 pairs of twins answerd the questionnaire asking social attainment, mental health and so on. Resting state of brain for IQ discrepant monozygotic twin paris (8 pairs) were investigated by fMRI and relationship between brain network in left Inferior Temporal Gyrus and IQ was found. It was also suggested that genetic contribution of prosocial behavior differed according to social situation.

    Toulmin's Model of Argument has been frequently used in argument education and informal logic. This study investigated the educational effects of this model and argument chart often used in critical thinking education, by measuring the critical and logical thinking abilities before and after the courses with each of these models.
    This study also showed that (1) Toulmin's Model of Argument is better understood as a normative model rather than a descriptive model which covers all types of arguments, and (2) some modification is needed for the model in order to grasp the dynamic flows of arguments.

    The participants of this large-scale longitudinal study were children (childhood through adulthood) and their parents, and they were followed up by yearly questionnaire for three years. First of all, we cross-sectionally studied change in Quality of Life (QOL) status by age. Next, through the analysis of longitudinal data obtained, we showed that decreased QOL may lead to poorer mental health.
    Additionally, longitudinal analysis of school-aged children’s QOL suggested that low-household income leads to poor parental child care quality and less educational investment which in turn affect children’s academic performance, QOL, school adjustment, and mental health status.

    平成21年度は,前年度から継続して48ヵ月齢までの双生児対象の調査を行った。また,特に学校の教育環境の影響に焦点を当てた,高校生双生児世帯を対象とする調査を行った。解析については,サンプルサイズが累積した最終月齢である48ヵ月齢までの縦断データ,および前年度までに得られた幼児期から青年期に至る横断データに対して行った。
    まず,出生以後の環境について,幼児期の親の養育行動と子の問題行動の間の因果関係を明らかにすることを試みた。具体的には,42ヵ月から48カ月にかけての縦断データセットを用いて,遺伝的影響,共有環境の影響を統制したうえで,より「純粋な」環境の効果を反映する非共有環境の影響についてパス解析を行った。この結果,表現型の相関関係から「よい」とされる親の養育行動は必ずしも子の問題行動を減らさず,むしろ増やす場合があること,また親の養育行動は子の問題行動の種類に応じて異なった影響を与えることが示された。また,出生前胎内環境の効果について検討するため,幼児期以降青年期までの双生児データを解析し,出生時の身体的特徴が,遺伝と共有環境の効果を統制したうえでなお気質および問題行動に対し環境を通じた影響を与えることを明らかにした。
    この他,前年度の調査において得られた中高生双生児世帯のデータを用いた分析を行い,子の道徳意識の低さが親の厳格なしつけを引き出す一方で(遺伝的相関関係),親の厳格なしつけは子の道徳意識を高めるように作用する(共有環境的相関関係)ことを明らかにした。また,国際双生児比較データを用いたパーソナリティ測定の信頼性・妥当性に関する方法論的検討を行い,異なる種類の信頼性指標を遺伝率が峻別することを明らかにした。また,知能や学力,性役割パーソナリティや性同一性障害など様々な変数について行動遺伝学的解析を行った。これらの成果は論文として採択済みまたは投稿中である。

    エフォートフル・コントロール(EC)は,実行注意の効率を表す気質で,非顕在的な反応を行うために顕現している反応を抑制する能力をさす.申請者は,前年度までにEC尺度の信頼性・妥当性,遺伝的斉一性を明らかにするとともに,ECの低さが外在化問題行動(衝動性が極端に高い場合に生じる不適応;ADHD,行為障害,物質乱用などの総称),抑うつ・不安などの内在化問題行動の両方の遺伝的素因である可能性を明らかにしてきた。
    本年度は,まず(1)「因果の方向性モデル」という手法を用いて昨年度までに得られたデータの再解析を行い,ECと問題行動との関連が年齢とともに変化することを明らかにした(博士論文の一部,学会発表)。また,(2)ECの成人期における発達的結果と考えられている勤勉性・協調性について,アメリカの双生児サンプルの二次データ(National Survey of Midlife Development in the United States ; MIDUS)を用いて,宗教性の個人差が勤勉性,協調性への遺伝的・環境的影響の強さを調節することを明らかにした(投稿中)。
    この他,(3)衝動性についての気質モデルの行動遺伝学的な妥当性および発達的変化について検討し(パーソナリティ研究,Personality and Individual Differences,ともに印刷中),また(4)アメリカ・ドイツの研究者との共同研究を行い,他者評定によって得られた双生児のパーソナリティのデータを用いて,パーソナリティの5次元構造の高次因子が認知的バイアスによるartifactである可能性を示唆した(投稿中)。
    最後に,(5)パーソナリティ研究における行動遺伝学的知見と今後の展望をまとめ,Handbook of Behavior Geneticsの一章にまとめた(印刷中)。
