Perspective Effects on Recall in a Testimony Paradigm.

The two present studies examined the influence of perspective instructions given during encoding and retrieval on the recall of a visual event. Participants viewed slides or a film depicting a day in the life of a man. Before viewing the to-be-remembered event, they were instructed to adopt the perspective of an alcoholic vs. an unemployed man vs. no perspective (Experiment 1), or of an unemployed man vs. no perspective (Experiment 2). Participants in the first study were interviewed twice, with the second recall being preceded by either a change perspective instruction or without any specific instruction. In the second study, participants were interviewed using either a cognitive interview (CI) or a CI without the change perspective instruction. Results showed that adopting a perspective during encoding impaired recall performance and failed to demonstrate a significant benefit of the change perspective instruction. The theoretical and practical implications of these results are discussed.

Enhancing Older Drivers' Safety: On Effects Induced by Stereotype Threat to Older Adults' Driving Performance, Working Memory and Self-Regulation.

In a study concerned with driving behaviors of older drivers (mean age 70 years) in a driving simulator, our findings indicate that telling older drivers that they are more at risk of accidents because of their age and their driving performance-related decline (i.e., exposing them to a stereotype threat concerning older drivers) severely impairs their self-regulatory skills. Moreover, our results show that this is at least partly due to exhaustion of the executive resources (older drivers under stereotype threat tended to contradict the stereotype of being slow by driving faster), appearing also through working memory overload (older drivers under stereotype threat performed markedly less well in a modular arithmetic task than drivers in the control condition). We thus complete the existing evidence that older drivers' performance may be affected by socially-grounded factors, suggesting that simply being investigated may be enough to tax many capabilities in older people. We also propose that stereotype threat might be at least a partial explanation for why older drivers sometimes have poorer self-regulation performances after attending rehabilitation programs designed to make older drivers safer ones.

The cognitive interview: is its benefit affected by the level of witness emotion?

This research investigated whether a witness's emotion could influence the accuracy of statements obtained by the use of a cognitive interview. A total of 70 first-year university students viewed a video depicting a road accident. Electrodes were attached to their arms in order to send fictitious electric shocks during the video (high-arousal condition) or to measure physiological signs (low-arousal condition). One week later, they were interviewed using either a cognitive interview (CI) or a structured interview (SI). It was hypothesised that the beneficial effect of the cognitive interview would be amplified by a high level of arousal, particularly concerning central aspects of the video. Results indicated that a CI elicited more correct central and peripheral details recalled, whatever the level of arousal inducted during the encoding of the to-be remembered event. Furthermore, high-arousal participants produced more accurate testimonies concerning peripheral details than participants exposed to a low level of arousal. No interaction between interview and emotion was found. The theoretical and practical implications for interviewing witnesses are described.
