Data from 396 real estate salespeople offer structural model evidence of the antecedence of salesperson cognitive style (Jung, 1971) to adaptive selling behavior, and to sales orientation-customer orientation and self-perceived selling performance. Four hypotheses were supported: Salespeople who prefer information intake by intuiting (rather than sensing) and information processing/decision-making by thinking (rather than feeling) were found to be more likely to practice adaptive selling; the more adaptive selling was practiced, the greater customer orientation became; and the greater the customer orientation, the better the self-perceived selling performance. Implications exist for salesperson training, management, and motivation research.
