About this Lecture

Lecture

In this lecture, we think about the effect of anxiety and stress on memory, focusing in particular on: (i) contrasting findings between forensic and memory research, the former suggesting that stress has a negative impact on memory performance, while the latter suggests that stress at the time of encoding can enhance memory performance; (ii) the Yerkes-Dodson curve as one example of how anxiety and stress might impact memory performance; (iii) Deffenbacher’s research into the negative effects of stress on eye witness memory performance; (iv) Loftus’ research on the weapons focus effect; (v) findings from memory research which suggest that stress during the time of encoding can enhance memory performance for information related to that stressor, while impairing recall of unrelated information; (vi) Yuille and Cutshall’s 1986 study, which found eye witness memory to be robust; (vii) their findings that real world event memories are less susceptible to weakening through stress, leading questions and the weapons focus effect, when compared to lab-based study generated memories; (viii) the proposal that the lack of emotional response to events in a lab-based study are what leave them susceptible to factors which have been shown to impair memory performance.

Course

This course, by Dr Adam Charles Harvey (University of the West of England) explores factors which impact the accuracy of eye witness testimony. In the first lecture, we think about the factors which impact eye witness memory in the criminal justice system. In the second lecture, we think about the impact of leading questions on the reliability and accuracy of eye witness testimony. In the third lecture, we think about the effects of post event discussion on eye witness memory. Next, we think about the reconstructive nature of memory, with a focus on Bartlett’s work and responses to it. In the fifth lecture, we think about context dependant memory. In the sixth and final lecture, we think about the impacts of anxiety and stress on memory performance.
