Abstract

Commitment is an important determinant of relationship stability. Previous studies demonstrated that relationship stability is influenced by several personality variables, one of which is conscientiousness. To account for the influence of conscientiousness on relationship stability, we propose a neurological model of commitment. The model assumes that conscientiousness and commitment are influenced by individual differences in anterior and mid-dorsolateral prefrontal (amDLPFC) functioning, and that conscientiousness is a partial mediator of the association between amDLPFC functioning and commitment. Results from two studies with dating couples are consistent with this model. Study 2 suggests that, relative to other conscientiousness facets, self-efficacy is a more likely mediator of the effect of amDLPFC functioning on commitment.
