Two experiments were conducted to test competing accounts of the distraction-persuasion relationship, thought disruption and effort justification, and also to show that the relationship is not limited to counterattitudinal communication.

The effort notion implied no interaction with message counterarguability. Exp II, with 54 undergraduates, again varied distraction but the 2 messages took a nondiscrepant position. One message elicited primarily favorable thoughts, and the effect of distraction was to reduce the number of favorable thoughts generated; the other, less …
