Acute Stress Impacts Executive-Social Function: Evidence From Prefrontal Activation and fNIRS-Based Hyperscanning.

ABSTRACT:

Background

Acute stress has complex effects on executive function and social behavior; however, the direction of these effects is inconsistent across studies, and the underlying neural mechanisms remain poorly understood. This study investigated the behavioral and neural effects of acute stress on executive function and dyadic cooperation and their relationships.

Methods

Eighty-six healthy male undergraduates (18-25 years) were randomly assigned to stress (n = 44; Trier Social Stress Test for Groups [TSST-G]) or control groups (n = 42; placebo TSST-G). The participants completed executive function tasks (3-back, Go/Nogo, Stroop, and task-switching) and cooperative button-pressing tasks pre- and postintervention, with a counterbalanced order.
