In this experiment, it was examined whether it is possible to detect what was presented subliminally when feedback (correct or incorrect) was given. Sixteen healthy right-handed undergraduate and graduate students were participated as subjects. Three (facial emotions: angry, happy, neutral) x three (feedback: available, no, random) factors were located within a subject. After a mask stimulus (neutral face) was presented, subjects were required to answer what was presented as a prime face by pressing one of three buttons. After subject's response, feedback was given as "correct" or "wrong" in feedback-available condition and "00000" in no feedback condition. In random feedback condition, the probability of presenting "correct" and "incorrect" was fixed as 3:7. ANOVA was performed on result of RT, hit rate, and d'. As for RT, the main effect of feedback was significant. As for hit rate, the interaction between facial expressions and feedback conditions was significant. Multiple comparison corrected by LSD on angry face revealed marginal significance between feedback-available and no-feedback, and significant difference between random-feedback and no-feedback. On neutral face, significant difference was found between feedback-available and no-feedback, and feedback-available and random feedback. In angry face condition, hit rate was lower than other conditions, and in neutral face condition, feedback-available condition showed lower hit rate than other conditions. About d', significant difference was not found among conditions. From above, it could be said that in no-feedback condition primed stimuli tend to be judged as neutral, but as long as feedback was given, subject's judgments shifted to answer that the prime was angry face.

Innate immune cells such as natural killer increase and acquired immune cells such as T cells decrease accompanying acute stress (redistribution of lymphocytes). This study examined effects of controllability of an acute stressor on the redistribution of lymphocytes. It was clarified that redistribution is suppressed in an uncontrollable situation. We further clarified mediating mechanisms of the phenomena and discussed significance of the phenomena in adaptation.

Although the neural basis of the unconscious priming effect has previously been investigated, the results of these studies have possibly been contaminated by a conscious priming effect. The aim of the present study was to dissociate the effects of conscious and unconscious priming on event-related potential (ERP) by using the process-dissociation procedure. A prime word was presented briefly, followed by a word-stem, in each trial. Under the inclusion condition, subjects were instructed to complete the word-stem using the prime word, while under the exclusion condition subjects were asked to complete the word-stem with a word not seen as prime. The behavioral priming effect was obtained under both conditions, indicating that the prime words were processed unconsciously and influenced the word-stem completion task. We found that two ERP components were affected by repetition priming. First, the N400 amplitude was decreased by word repetition under the inclusion condition, but not under the exclusion condition. This result suggests that N400 would reflect conscious lexical processing, but not unconscious lexical activation. Second, the negativity at left front lateral region was enhanced by word repetition under the exclusion condition. We discuss this finding herein in relation to the activity of the left inferior prefrontal cortex with regard to word semantic processing. (c) 2004 Elsevier Ltd. All rights reserved.

Acute experimental Stressors transiently increase volume of secretory immunoglobulin A (s-IgA) in saliva. The present study examined buffering effects of social support on response of s-IgA to a brief psychological stress (giving a public speech), 24 women were divided at random into three groups, an emotional support group, an informational support group and a no-support group (control). For each group, s-IgA measures were obtained from each person under baseline conditions, during preparation of a speech when social support or no support was given, immediately after the speech and during a 'recovery' period. Level of s-IgA in the control group significantly elevated during preparation for the speech and just after the speech compared to baseline, suggesting that the speech task stimulated secretory immune function. On the other hand, the subjects in the emotional support group showed increased s-IgA during the preparation period but secretion of s-IgA rapidly returned to the baseline after the speech task. Secretion of s-IgA in the informational social support group was unchanged at any measurement point. These results suggest that social support attenuates the affect of a Stressor on somatic state.

Previous studies have indicated that expression of negative emotions facilitates mental and physical health and inhibition of negative emotions increases susceptibility to illness. This study was conducted to examine whether those findings can be expanded to populations with non-Western cultural backgrounds. Specifically, we explored effects of expression and inhibition of negative emotions on health, mood states, and mucosal immune function in mildly depressed Japanese individuals. 16 depressed and 16 nondepressed female undergraduates were required either to write about their unpleasant experiences and superficial topics or to suppress any emotional responses and thoughts about them. Secretory immunoglobulin A (s-IgA) in saliva and psychological indices were measured at an experimental session and at a follow-up 1 wk. later. Beneficial effects of expression of emotions on subjective health were indicated in the nondepressed group, whereas harmful effects of inhibition on subjective health were shown in the depressed group. Emotional expression by writing improved mood states both in the depressed and nondepressed groups but induced elevation of salivary s-IgA only in the depressed group.
