Dissociative experience and mood-dependent memory Reviewed

Amnesia is the main phenomenon in dissociative experiences. The present study investigated whether amnesia in participants with frequent dissociative experiences depended on state-dependent memory. Undergraduates scoring high (n = 32) or low (n = 32) on the Dissociative Experiences Scale Version-II (DES-II) participated in this experiment. Mood induction and a remember/know task were used in a typical mood-independent memory design. In the inconsistent mood state condition, participants in the high DES group showed decreased memory performance compared to the low DES group. These results were attributed to the recollection components of recognition and not to the familiarity component. Therefore we concluded that the normal population with highly frequent dissociative experiences showed strong state-dependent memory and had a memory bias in the recollection component of memory.

Several studies reported that redistribution of lymphocyte subsets, especially CD3-CD16+CD56+ natural killer (NK) cells, was elicited by acute psychological stress tasks. It is known that lymphocyte redistribution was regulated based on active or passive emotional coping strategies, which can be elicited dependent on controllability of a stressor. Controllability can be evaluated gradually by learning of a contingency between actions and outcomes. Therefore, lymphocyte redistribution can be determined by learning of the contingency. To examine this issue, we used a stochastic learning task as an acute stress task and divided twenty healthy participants into reinforcement or yoked groups. Between the two groups, only whether they could learn the contingency was manipulated. As a result, patterns of changes in the NK cell numbers differed between the groups; NK cells remarkably increased at first and then gradually decreased to the baseline in the reinforcement group while the yoked group showed a moderate but sustained increase of NK cells. These patterns of changes in the NK cells were completely parallel with changes of the cardiovascular parameters but not with secretion of catecholamines. The present results suggest that cardiovascular and immune reactivity can be modulated along with progresses of adaptation for an acute stressor. (C) 2007 Elsevier Inc. All rights reserved.

Influence of attention manipulation on emotion and autonomic responses.

Murakami H, Ohira H

Perceptual and motor skills Vol. 105 ( 1 ) page： 299 - 308 2007.8

Language：English Publishing type：Research paper (scientific journal) Publisher：Perceptual and Motor Skills

Psychopathologies such as depression and anxiety have been associated with self-consciousness, a trait focusing on the self in terms of emotions and social images. A technique designed to shift attention away from the self tends to reduce anxiety, so the present purpose was to assess the effect of self body-state information on an individual's emotional and autonomic activity. 24 undergraduate and graduate students (10 men and 14 women), ages 19 to 27 years (M = 22.1, 5D = 2.5), were recruited as subjects. Focusing on body-state during an anxiety-inducing situation led to an increase of low to high frequency ratio of heart-rate variability which reflected cardiac sympathovagal balance. That is, attending to one's own bodily states enhanced relative sympathetic activity compared to parasympathetic activity, which can be interpreted as one of the physiological emotional responses elicited by anxiety. © Perceptual and Motor Skills 2007.
