Dynamic versus static indicators of threat: N2 and LPC modulation index attack intent and biological relevance during an affective Flanker task.

Biological relevance may influence the neural response towards images which depict attack intent. In the present study, images featuring reptiles and firearms were employed as target and flanking stimuli in a modified version of the affective Flanker task. Forty-two participants (21 male) completed the modified Flanker task as EEG was recorded.

Habitual exercise affects inhibitory processing in young and middle age men and women.

Inhibitory processing is an aspect of cognitive control susceptible to cognitive decline due to aging. Engaging in habitual exercise could attenuate these declines in middle age. In the present study, the event-related potential (ERP) activity of 40 middle age adults (21 females) and 42 young adults (24 females) was recorded with electroencephalography (EEG) as participants completed two cognitive tasks that elicit inhibitory processing, one indexing interference control (i.

Deconstructing threat: Rethinking the interplay between biological and social relevance in the emotional salience of unpleasant images.

The type of threat shown in an image influences the emotional salience of unpleasant images. Seventy-four participants (21 male) rated high threat, moderate threat, and neutral images featuring reptiles, firearms, or humans as electroencephalographic activity was recorded. The magnitude of P3b amplitudes coincided with the threat level of firearm and human images, whereas scenes of attacking snakes and aimed handguns evoked more positive late positive component (LPC) activity than non-attacking or neutral versions of these same stimuli.

An event-related potential investigation of age and sex in face categorization: Participant sex matters.

Whether a face is categorized as male or female is influenced by the age of the face. In the present study, Event-Related Potential (ERP) measures were employed to offer insight into the neural correlates indexing the interaction between the age and sex of a face during sex categorization. Thirty-eight young adults (18 male) categorized the sex of young (18-29 years) and older (70-94 years) adult faces as ERP activity was recorded.
