title: Chronic self-perceived stress and set-shifting performance in undergraduate students.
abstract: Given recent findings on the potential for detrimental effects of chronic stress on the prefrontal cortex, additional research on the relationship between chronic stress and performance on executive functioning tasks (dependent on prefrontal functioning) is needed. Eighty-one undergraduate students completed a self-report measure of stress over the previous month (perceived stress scale--PSS) and the comprehensive trail-making test (CTMT, Trials 3 and 5). Results revealed a statistically significant positive correlation between PSS score and time needed to complete Trial 5 of the CTMT, which places demands on the set-shifting component of executive functioning. This finding adds to a growing body of work that suggests a relationship between chronic stress and executive functioning, and extends these findings to include set-shifting performance.
