ABSTRACT
Explanatory style affects a person’s mental and physical health in important ways (see Peterson & Seligman, 1984a). Although these effects are well documented, we know little about the origins of individual differences in explanatory style. What makes one person optimistic and another person pessimistic? In this chapter, I explore answers to this question. I first review previous work examining the determinants of explanatory style. Next, I propose that trust of intimate others also affects the development of individual differences in explanatory style. Finally, I report a study that tests the impact of trust on explanatory style.
