Over multiple response opportunities, recall may be inconsistent. For example, an eyewitness may report information at trial that was not reported during initial questioning-a phenomenon called reminiscence. Such inconsistencies are often assumed by lawyers to be inaccurate and are sometimes interpreted as evidence of the general unreliability of the rememberer. In two experiments, we examined ...

Involuntary autobiographical memories are spontaneously arising memories of personal events, whereas voluntary memories are retrieved strategically. Voluntary remembering has been studied in numerous experiments while involuntary remembering has been largely ignored. It is generally assumed that voluntary recall is the standard way of remembering, whereas involuntary recall is the exception. Ho...

We performed an event-related fMRI study comparing attempts at suppressing recall of negative versus neutral memories. The hippocampus is crucial for successful explicit recall. Hippocampal activation has been shown to decrease during the suppression of previously learned neutral words. However, different effects may occur in the case of emotional memories. Participants first learned 40 word pa...

The story of our lifetime - our narrative self - is constructed from our autobiographical memories. A central claim of social psychology is that this narrative self is inherently social: When we construct our lives, we do so in a real or imagined interaction. This predicts that self-referential processes which are involved in recall of autobiographical memories overlap with processes involved i...

Rapid and selective erasures of certain types of memories in the brain would be desirable under certain clinical circumstances. By employing an inducible and reversible chemical-genetic technique, we find that transient alphaCaMKII overexpression at the time of recall impairs the retrieval of both newly formed one-hour object recognition memory and fear memories, as well as 1-month-old fear mem...

Body posture reflects emotional states, and this study investigates the effect of posture sitting in a slouched or upright position on recall of either negative (hopeless, helpless, powerless, or defeated) memories or positive (empowered or optimistic) memories. Two hundred and sixteen college students sat in either a slouched or an erect position while recalling negative memories and then in a...

False memory creation was examined in people who reported having recovered memories of traumatic events that are unlikely to have occurred: abduction by space aliens. A variant of the Deese/Roediger-McDermott paradigm (J. Deese. 1959; H. L. Roediger III & K. B. McDermott, 1995) was used to examine false recall and false recognition in 3 groups: people reporting recovered memories of alien abduc...
