Abstract
The goal of this research was to examine whether memories for actions can be affected by information reported by another person. In two studies, pairs of participants performed 48 of a set of 96 actions. In Study 1, both members of the pairs performed the same actions, and in Study 2, they performed different actions. One week later, the members of the pairs were questioned together about whether they had or had not done all 96 actions. What one person reported greatly influenced what the other person reported for both correct and incorrect responses. This influence was maintained when the participants were later tested individually, and the participants described having pictorial memories for doing many of the actions that they had not done but had merely been suggested.
