Trait positive affect and students' prefrontal EEG alpha asymmetry responses during a simulated exam situation

Affective dispositions may shape students' typical ways of coping when faced with demanding performance situations in their educational lives. We recorded frontal EEG alpha asymmetry responses in psychology students (n = 62) during the course of a scenario designed to simulate a real examination, which required oral explanation of statistical concepts. While students with lower levels of trait positive affect (PANAS) showed relative right hemispheric activation, sustained relative left hemispheric activation was observed in students with higher levels of trait positive affect. In line with relevant models of frontal brain asymmetry, the findings suggest that students' coping behaviors in the context of academic performance situations are in part instantaneously initiated, which is reflected in spontaneous activation of relative approach versus avoidance motivation. Independently of negative affect and momentary affective states, trait positive affectivity seems to be linked to recruitment of brain processes supporting a more adaptive response in that matter.
