Abstract
In two experiments recognition of actions of a robbery presented in a video was examined in older and younger adults. In both experiments older adults had more false alarms and showed less accurate recognition than younger adults. In addition, when participants were asked in Experiment 1 to indicate Remember/Know/Guess judgments for actions they considered true, older adults accepted more false actions with Remember judgments. And when participants were asked in Experiment 2 to attribute the source (i.e., perpetrator), the older adults were less able to attribute actions that occurred during the robbery to their correct sources. Furthermore, we found a robust positive correlation between source attribution ability and recognition accuracy. Thus, source-memory deficits may contribute to older adults' false memories in real-life eyewitness situations.
