Emotion regulation and amygdala-precuneus connectivity: Focusing on attentional deployment

Attentional deployment is an emotion regulation strategy that involves shifting attentional focus. Deploying attention to non-arousing, compared to arousing, regions of unpleasant images has been associated with reduced negative affect, reduced amygdala activation, and increased activity in fronto-parietal control networks. The current study examined neural correlates and functional connectivity associated with using attentional deployment to increase negative affect (deploying attention towards arousing unpleasant information) or to decrease negative affect (deploying attention away from arousing unpleasant information), compared to naturally viewing unpleasant images, in 42 individuals while concurrently monitoring eye movements. Directing attention to both arousing and non-arousing regions resulted in enhanced fronto-parietal activation compared to natural viewing, but only directing attention to non-arousing regions was associated with changes in amygdala activation. There were no significant differences in connectivity between naturally viewing unpleasant images and focusing on arousing regions. However, naturally viewing unpleasant images, relative to focusing on non-arousing regions, was associated with increased connectivity between the amygdala and visual cortex, while focusing on non-arousing regions of unpleasant images, compared to natural viewing, was associated with increased connectivity between the amygdala and the precuneus. Amygdala-precuneus connectivity correlated positively with eye-tracking measures of attentional deployment success and with trait reappraisal. Deploying attention away from arousing unpleasant information, then, may depend upon functional relationships between the amygdala and parietal regions implicated in attentional control. Furthermore, these relationships might relate to the ability to successfully implement attentional deployment, and the predisposition to utilize adaptive emotion regulation strategies.     

Positive psychological approaches to therapy

The term positive psychology has become widely used in recent years to refer to the new movement among psychologists who have turned their attention to positive human functioning. In this article we will review what the emerging field of positive psychology tells us about therapeutic practice. The positive psychology movement has led to a questioning of the fundamental assumptions underlying the practice of psychological therapy, and it is our view that the emerging positive psychology research is supportive of those therapeutic approaches which serve to facilitate the client's ability to hear their own inner voice.     

Fantasy,defense, and the representational world

This paper discusses the manipulation of mental representations, particularly in relation to the psychoanalytic concepts of conscious or unconscious fantasy. A distinction is made between the unconscious phenomenal (experiential) aspect of representations and the nonexperiential, quasi-structural aspect. The concept of the representational world is described and elaborated, and its development is seen as a consequence of the infant's interaction with itself and the external world. Processes such as identification and projection can be seen in terms of changes in self and object representations, and the same is true for all the mechanisms of defense. The content of unconscious wishes is transformed, by use of such mechanisms, into representations that are acceptable to consciousness. Major transformations of unconscious representational content occur in the process of creating unconscious (preconscious) fantasy, and further transformations are frequently needed before such (preconscious) fantasies are permitted access to consciousness. The concept of projective identification is considered in the light of the ideas put forward in the paper.     

Hemispheric differences in visual search of simple line arrays

Summary The effects of perceptual organization on hemispheric visual-information processing were assessed with stimulus arrays composed of short lines arranged in columns. A visual-search task was employed in which subjects judged whether all the lines were vertical (same) or whether a single horizontal line was present (different). Stimulus-display organization was manipulated in two experiments by variation of line density, linear organization, and array size. In general, left-visual-field/right-hemisphere presentations demonstrated more rapid and accurate responses when the display was perceived as a whole. Right-visual-field/left-hemisphere superiorities were observed when the display organization coerced assessment of individual array elements because the physical qualities of the stimulus did not effect a gestalt whole. Response times increased somewhat with increases in array size, although these effects interacted with other stimulus variables. Error rates tended to follow the reaction-time patterns. The results suggest that laterality differences in visual search are governed by stimulus properties which contribute to, or inhibit, the perception of a display as a gestalt. The implications of these findings for theoretical interpretations of hemispheric specialization are discussed.
