Spatiotemporal Dynamics of Affective and Semantic Valence Among Women.

As an important dimension of emotional assessment, valence can refer to affective valence reflecting an emotional response, or semantic valence reflecting knowledge about the nature of a stimulus. A previous study has used repeated exposure to separate these two similar cognitive processes. Here, for the first time, we compared the spatiotemporal dynamics of the affective and semantic modes of valence by combining event-related potentials with repeated exposure.

Trait anxiety modulates the temporal dynamics of Stroop task switching: An ERP study.

The current study aimed to find neural evidence that trait anxiety interferes with one's shifting function processing efficiency. Twenty-five high trait-anxiety (HTA) and twenty-five low trait-anxiety (LTA) participants were instructed to complete a cue-based Stroop task-switching assessment of shifting function. No group difference in behavioral performance was shown, though event-related potential (ERP) results in the cue-locked period showed that only the LTA group had a general switch benefit in contingent negative variation (CNV) amplitude, indicating the LTA group exerted less task preparation effort.

Regulation of negative emotions through positive reappraisal and distancing in high-trait-anxious women.

Background: Positive reappraisal and distancing are two distinct cognitive reappraisal strategies for emotion regulation. Critically however, research examining the impact of elevated trait anxiety on cognitive reappraisal has often conflated these strategies. Thus, the present study investigated whether high-trait-anxious (HTA) women can effectively utilize positive reappraisal and distancing to regulate emotional responses to negative stimuli.
