Although there has been steady progress elucidating the influence of emotion on cognition, it remains unclear precisely when and why emotion impairs or facilitates cognition. The present study investigated the mechanisms involved in the influence of emotion on perception and working memory, using modified 0-back and 2-back tasks, respectively. First, results showed that attentional focus modulated the impact of emotion on perception. Specifically, emotion facilitated perceptual task performance when it was relevant to the task, but it impaired performance when it (...) was irrelevant to the task. The differential behavioural effect of emotion on perception as a function of attentional focus diminished under high WM load. Second, attentional focus did not directly modulate the impact of emotion on WM, but rather its influence depended on the dynamic relationship between internal representations. Specifically, WM performance was worse when the material already being held online and the new input were of matching emotions, compared to when they were not. We propose that the competition between “bottom-up” and “top-down” processing for limited cognitive resources explains the nature of the influence of emotion on both perception and WM. (shrink)

Individuals with social anxiety disorder engage in post-event processing, a form of perseverative thinking. Given that deficits in working memory might underlie perseverative thinking, we examined working memory in SAD with a particular focus on the effects of stimulus valence. SAD and healthy control participants either maintained or reversed in working memory the order of four emotional or four neutral pictures, and we examined sorting costs, which reflect the extent to which performance deteriorated on the backward trials compared to the (...) forward trials. Emotionality of stimuli affected performance of the two groups differently. Whereas control participants exhibited higher sorting costs for emotional stimuli compared to neutral stimuli, SAD participants exhibited the opposite pattern. Greater attention to emotional stimuli in SAD might facilitate the processing of emotional stimuli in working memory. (shrink)

In my original review (Kensinger, 2009), I proposed that to understand the effects of emotion on memory accuracy, we must look beyond effects of arousal and consider the contribution of valence. In discussing this proposal, the commentators raise a number of excellent points that hone in on the question of when valence does (and does not) account for emotion's effects on memory accuracy. Though future research will be required to resolve this issue more fully, in this brief response, I address (...) some of the concerns outlined by the commentators and suggest a few steps that may help to elucidate the dimensions that should be incorporated in models of emotional memory.
