Evaluation Based On Their Episodic Memory - 1745 Words

Introduction Eyewitnesses are required to provide testimony based on their episodic memory to aid the investigation in courtroom. Idealistically, eyewitnesses are able to provide details of crime scene accurately. However, the interference during the process of encoding and retrieval of episodic memory may impair eyewitnesses’ memory. In Megreya and Burton (2008) research, it was found that witnesses were less capable to encode faces in traumatic events. Because of flashbulb effect, some witnesses may hold a belief that they can vividly remember the details of crime scene despite their memory was somehow flawed. It poses an adverse effect on criminal justice system as the subjective judgment of eyewitnesses’ identification contributed to more than 75% occurrence of 239 DNA exoneration cases. (Ask Granhag, 2010). During the retrieval process, Therefore, cognitive psychologists and scientists conducted decades of methodological research to improve the accuracy of eyewitn esses’ memory. This essay would mainly focus on how ‘cognitive interview’, one of the widely studied scientific techniques since 1980s that corrects the errors and deficiencies of memory retrieval during conventional police interview. Discussion Police often relied on eyewitnesses’ testimony to determine the solution of cases (ref). Before the development of cognitive interview, techniques like asking closed-ended questions and leading questions were frequently adopted in interview process (Loftus Zanni,Show MoreRelatedSummary : General Psychology.

The idea of bilingualism and its effect on memory is relatively new, but it is also considered as a rising topic in the field of psychology, linguistics, cognitive science, and second language studies. In 1993, Javier, Barroso, and Muà ±oz conducted a research with a group of Spanish-English bilingual speakers. They emphasized that language is a powerful retrieval tool and a cue toRead MoreDifferences Between Male And Female Brain1536 Words   |  7 PagesAre there physical differences in the male and female brain?

However, as a result of this research, it became apparent that there were a number of problems with their ideas concerning the characteristics of short-term memory. Building on this research, Baddeley and Hitch (1974) developed an alternative model of short-term memory which they called working memory.

However, the storage of information in humans involves three major processes i.e. encoding, storage, and retrieval. The encoding process basically involves transforming data into meaningful form like association with an existing image, memory, or sound. This is followed by holding on to the information through a physiological
