False memories of having said the unsaid: on the importance of a prior intention to speak

Previous research found that adults who participated in a mock debate often later reported having made a point that they had not. In an extension of that study, the present research not only replicated that finding but also investigated the possibility that such errors were the result of the subjects having been induced into intending to make the unmade point. Specifically, the present results show that the occurrence of the inducing stimulus probably did produce such intentions and that the stimulus was also important to the production of subsequent memory errors. Finally, it is argued that the latter errors are most parsimoniously understood as being caused by distorted memories of the intentions demonstrated by the former result.
