About this Lecture

Lecture

In this lecture, we think about the impact of leading questions on eye witness testimony, focusing in particular on: (i) the active nature of memory making it vulnerable to misleading information; (ii) Loftus and Palmer’s 1974 study, which demonstrates that eye witness memory is flexible and that this flexibility is susceptible to the language used during post-event questioning; (iii) the ability for post-event questioning to create a response bias, but also to change the eye witnesses memory itself; (iv) the results from Loftus and Palmer’s 1974 study, which showed that differing verb usage to describe a car crash altered the estimated speeds of the collision given by participants; (v) the competing hypotheses, one which proposing that the differing answers were due to response bias, and the other proposing that they were due to false memories; (vi) Loftus and Palmer’s second study, which demonstrated the presence of false memories under certain questioning conditions; (vii) the take home message from this study, that questioning can have a profound impact on eye witness reporting and memory.

Course

In this course, 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.
