Women in the midluteal phase of the menstrual cycle have difficulty suppressing the processing of negative emotional stimuli: An event-related potential study.

Emotion regulation deficits have been implicated in anxiety and depressive disorders, and these internalising disorders are more prevalent in women than men. Few electrophysiological studies have investigated sex differences in emotional reactivity and emotion regulation controlling for menstrual phase. Event-related potentials (ERPs) were recorded from 28 early follicular women, 29 midluteal women, and 27 men who completed an emotion regulation task.

The impact of high trait social anxiety on neural processing of facial emotion expressions in females.

A cognitive model of social anxiety predicts that an early attentional bias leads to greater cognitive processing of social threat signals, whereas the vigilance-avoidance model predicts there will be subsequent reduction in cognitive processing. This study tests these models by examining neural responses to social threat stimuli using Event-related potentials (ERP). 19 women with high trait social anxiety and 19 women with low trait social anxiety viewed emotional expressions (angry, disgusted, happy and neutral) in a passive viewing task whilst ERP responses were recorded.

Early visual processing is enhanced in the midluteal phase of the menstrual cycle.

Event-related potential (ERP) studies have revealed an early attentional bias in processing unpleasant emotional images in women. Recent neuroimaging data suggests there are significant differences in cortical emotional processing according to menstrual phase. This study examined the impact of menstrual phase on visual emotional processing in women compared to men.

Gender differences in salivary alpha-amylase and attentional bias towards negative facial expressions following acute stress induction.

This study investigated gender differences in two key processes involved in anxiety, arousal and attentional bias towards threat. Arousal was assessed using salivary alpha-amylase (sAA), a biomarker of noradrenergic arousal and attention bias using a dot-probe task. Twenty-nine women and 27 men completed the dot-probe task and provided saliva samples before and after a stress induction [cold pressor stress (CPS) test].

Sex differences and emotion regulation: an event-related potential study.

Difficulties in emotion regulation have been implicated as a potential mechanism underlying anxiety and mood disorders. It is possible that sex differences in emotion regulation may contribute towards the heightened female prevalence for these disorders. Previous fMRI studies of sex differences in emotion regulation have shown mixed results, possibly due to difficulties in discriminating the component processes of early emotional reactivity and emotion regulation.
