Recalling A Witnessed Event Increases Eyewitness Suggestibility The Reversed Testing Effect, Jason C.K. Chan, Ayanna K. Thomas, John B. Bulevich

People's later memory of an event can be altered by exposure to misinformation about that event. The typical misinformation paradigm, however, does not include a recall test prior to the introduction of misinformation, contrary to what real-life eyewitnesses encounter when they report to a 911 operator or crime-scene officer. Because retrieval is a powerful memory enhancer (the testing effect), recalling a witnessed event prior to receiving misinformation about it should reduce eyewitness suggestibility. We show, however, that immediate cued recall actually exacerbates the later misinformation effect for both younger and older adults. The reversed testing effect we observed was ...

Conduct of a line-up involves police or line-up administrators in a number of important decisions, such as who to put in the line-up, the method of presentation of the line-up, and what to say to witnesses before and after the line-up. The identification test can be conceptualized as a variant on an interview between the police and the witness, involving important interactions between police (or other line-up administrators) and witnesses. These interactions can profoundly influence witness decisions and impact on ...


Expert Testimony Regarding Eyewitness Identification, Brian L. Cutler, Gary L. Wells Jan 2009

Expert Testimony Regarding Eyewitness Identification, Brian L. Cutler, Gary L. Wells

Psychology Publications

Increasingly, psychologists are giving expert testimony in court on the accu­ racy of eyewitness identification (Kassin, Tubb, Hosch, & Memon, 2001). Eyewitness experts typically are cognitive or social psychologists who have published research articles on the topic of eyewitness memory. Expert testi­ mony in eyewitness identification is most commonly offered by the defense in criminal cases but is occasionally countered by opposing expert testimony offered by the prosecution. The increasing use of such expert testimony owes largely to the growing recognition that mistaken eyewitness identification is the single most common precursor to the conviction of innocent people (Doyle, 2005). In addition ...
