Memory conformity and suggestibility

Abstract

The present study examined whether the degree to which participants engage in memory conformity, which occurs when a person alters their memory report of an event to be consistent with another person, can be predicted by their levels of interrogative suggestibility (IS), which is the degree to which people are susceptible to altering their memory reports during questioning. Memory conformity was introduced by having participant and confederate pairs study words and then complete a social recognition test where they took turns to make judgements to the same items. When the participants responded after the confederate, they tended to conform to confederate's judgements regardless of whether the confederate had made a correct or incorrect response. IS was measured using the Gudjonsson Suggestibility Scale 2. This scale allows separate measures of Yield, which is a measure of how susceptible people are to altering their memory reports of events as a result of leading questions, and Shift, which is a measure of how susceptible people are to changing responses to questions when placed under pressure to do so. Only Yield was a significant predictor of memory conformity.
