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. © 2007 Elsevier Inc. All rights reserved.

Influence of attention manipulation on emotion and autonomic responses.

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.

The present study investigated the abnormalities of cardiovascular responses to contextual or explicit emotional stimuli with respect to the two facets of psychopathy in a Japanese undergraduate population assessed by a Japanese version of the Primary and Secondary Psychopathy Scales. In study 1, recording heart rate and fingertip skin temperature while the participants watched an unpleasant movie, we found that the participants with high tendencies toward antisocial behavior (n = 16) showed smaller reactivity than those with low tendencies toward antisocial behavior (n = 16). By contrast, in study 2, heart rate orienting responses to affective slides were recorded, and the participants with high tendencies toward emotional detachment (n = 15) showed smaller responses to unpleasant slides than those with low tendencies toward emotional detachment (n = 16). Consistent with previous studies which recorded skin conductance and startle eye blink with psychopaths, these findings using a non-institutionalized sample also suggest that affective dysfunction in psychopathy is based on two specific physiological mechanisms.

The integration of multimodal stimuli has been regarded as important for the promotion of adaptive behavior. Although recent work has identified brain areas that respond to multimodal stimuli, the temporal features are not clear yet. Earlier event-related potential studies revealed crossmodal attention effects, but did not focus on mechanisms underlying crossmodal integration. Here, electroencephalography (EEG) activity in the gamma band was considered as a correlate of multimodal integration. Participants localized a tactile stimulus on their fingers while seeing visual stimuli on rubber hands with the same posture as their hands. EEG analyses using wavelet transform suggested that interelectrode phase synchrony in the gamma-band range (40-50 Hz) was related to behavioral indices of the intermodal illusion under consideration. The findings suggest a role of high-frequency oscillations in the integrative processing of stimuli across modalities. Copyright © 2007 Society for Psychophysiological Research.
