Affective effects on breadth of attention have been related to aspects of different components of affective states such as the arousal and valence of affective experience and the motivational intensity of action tendency. As none of these explanations fully aligns with existing evidence, we hypothesised that affective effects on breadth of attention may arise from the appraisal component of affective states. Based on this reconceptualisation, we tested the effects of conduciveness and power appraisals on two measures of breadth of attention. (...) In two web-based experiments, we manipulated these appraisals in a 2 × 2 design using a game-like arithmetic task where participants could (1) gain or lose rewards (goal conducive vs. obstructive) based on (2) either their action or the actions of a “robot” (high vs. low power). Breadth of attention was assessed using the flanker task (Experiment 1; n = 236) and the Navon task (Experiment 2; n = 215). We found that appraisals did not directly influence breadth of attention even though high power appraisal significantly improved the overall performance in both experiments indicating successful appraisal manipulation. We discuss ways in which these findings inform future efforts to explain the origins of affective effects on attentional breadth. (shrink)

Research on the asymmetric effect of negative versus positive affective states on scope of attention, both at a perceptual and a conceptual level, is abundant. However,...

Emotions can have both enhancing and impairing effects on various cognitive processes, from lower to higher level processes. The present article discusses emerging brain imaging evidence linking these opposing effects of emotion, which points to overlapping and dissociable neural systems involving both bottom-up and top-down mechanisms. The link between the enhancing and impairing effects is also discussed in a clinical context, with a focus on posttraumatic stress disorder, where these opposing effects tend to co-occur, are exacerbated, and are detrimental. Overall, (...) the present review highlights the need to consider together enhancing and impairing effects of emotion on cognition in studies investigating emotion–cognition interactions. (shrink)

ABSTRACTEmotions influence cognitive processes involved in memory. While some research has suggested that cognitive scope is determined by affective valence, recent models of emotion–cognition interactions suggest that motivational intensity, rather than valence, influences these processes. The present research was designed to clarify how negative affects differing in motivational intensity impact memory for centrally or peripherally presented information. Experiments 1 & 2 found that, relative to a neutral condition, high intensity negative affect enhances memory for centrally presented information. Experiment 3 replicated (...) this effect using another high intensity negative affect. Experiment 4 extended this by finding that, relative to a neutral condition, low intensity negative affect enhanced memory for peripherally presented information. Finally, in Experiment 5, the effects of sadness and threat on scope of memory were directly compared, finding that threat narrowed scope of... (shrink)
