title: The relationship between stress, hemispheric preference and decision making among managers.
abstract: Previous studies have shown important effects of stress on decision making (DM). In addition, individuals differ in their relative activation of the left and right hemispheres (hemispheric preference; HP), with possible implications for DM. This study tested the relationship between stress, HP and their interaction, with DM in managers. We included a sample of 114 managers from Israel, Italy and France. Stress was inversely and significantly related to DM thoroughness (r=-.333), left-HP (r=-.24) and was positively correlated with instinctiveness DM (r=.25; all p<.05). Importantly, a stress×HP interaction accounted for an additional and significant 9% of the variance in thoroughness, beyond their main effects, nationality and gender. In this interaction, only in right HP managers, but not in left HP managers, stress was inversely correlated with thoroughness. A stress×HP interaction was not found for instinctiveness. Theoretically, our results advise investigating both situational (stress) and personal or biological (HP) factors in the job stress field. Practically, it can guide stress specialists to whom to provide scarce counseling resources of stress management, to improve workers' DM and well-being.
