Do differences in general trust explain cultural differences in dispositionism?

It has been suggested that Westerners are more inclined than Easterners to endorse dispositionism. To help explain what produces this cultural difference, I examined the responses of Japanese and American students to determine whether levels of general trust, which is the expectation of benign or cooperative behavior based on the goodwill of another person (Yamagishi & Yamagishi, 1994), would matter. As predicted, in accounting for either a prosocial or deviant behavior, high trusters were more likely than low trusters to show dispositionism on all three measures (dispositional attribution, trait inference, and behavioral consistency), whereas cultural differences in dispositionism almost vanished. This tendency was found regardless of the desirability of behaviors.
