Post-Evaluative Biases Toward Somatic Stimuli and Cardiovascular Responses in Social Anxiety

Cognitive models of social anxiety emphasize the role of an attentional shift toward cues related to somatic state in social anxiety. We examined attentional biases to somatic cues and cardiovascular reactivity in response to a social evaluative task. Participants performed an impromptu speech during which they received standardized negative evaluative comments. Participants then completed a dot-probe task with social evaluative, somatic, and anger-related words. Blood pressure (BP) and heart rate (HR) were assessed in 1-minute intervals during baseline, the speech task, and the dot-probe task. Despite the fact that a high social anxiety group reported higher levels of anxiety, high and low social anxiety groups did not differ in their speech task-evoked BP or HR responses. Furthermore, the high social anxiety group, compared to the low social anxiety group, exhibited greater attentional biases to somatic words, suggesting greater attention directed toward information pertinent to somatic arousal.     

Avoidant attachment and hemispheric lateralisation of the processing of attachment‐ and emotion‐related words

Studies of adult attachment indicate that intimacy avoidance is associated with general negative emotionality and withdrawal from potentially positive aspects of social relations. Such emotional negativity and withdrawal motivation have been connected in psychophysiological studies with the right frontal lobe of the brain, whereas the left frontal lobe specialises in emotional positivity and approach behaviour. In the present study we used a divided visual field task to investigate hemispheric asymmetries in making decisions about the positivity or negativity of attachment‐ and emotion‐related words, as well as various kinds of control words. We found that more avoidant individuals made more errors when judging positive attachment‐related words presented to the right hemisphere. The findings are discussed in terms of possible effects of attachment history on the way attachment‐related information is processed in the brain.     

Suicide in the Medically Ill

“The undiscover'd country, from whose bourn No traveler returns puzzles the will, And makes us rather bear those ills we have Than fly to others that we know not of?” (Hamlet III, i)     

Complex movement patterns: Learning retention and sources of error in recall

In this study of kinaesthesis, the learning, retention, and recall of complex patterns was examined. Subjects were blindfolded, held a stylus in the right hand, and moved around stencil patterns, either actively or passively. The patterns were recalled with a free active movement of the right hand, after various amounts of practice, immediately or after a 60-s interval, once or twice in succession, with and without visual guidance. The shape and size of the drawings was compared with the criterion patterns. The effect of practice varied depending on whether the criterion movement was active or passive, and on the measure of recall performance. Even when the criterion patterns were freely practised, the recall traces showed large errors in shape and systematic shrinkage in size, and there were large individual differences. Regardless of these errors, recall performance was reliable. The effect of an unfilled retention interval varied as a function of practice. When the patterns were recalled under visual guidance, there was no shrinkage in the size of the drawings.
