Literature Review

Social scientists have long been interested in the accuracy of eyewitness testimony. Several studies over the past few decades have demonstrated that eyewitnesses are not always accurate (e.g., Buckhout, 1974; Bornstein & Zickafoose, 1999). More recently, many individuals have filed appeals based on deoxyribonucleic acid (DNA) evidence. Of those acquitted on this basis, 78 percent had originally been convicted based on strong eyewitness testimony (Stambor, 2006). One reason witnesses may err when recalling information about a criminal is the misinformation effect, which involves "incorporating 'misinformation' into one's memory of the event after receiving misleading information about it" (Myers, 2008). Elizabeth Loftus (1978, 1979a, 1979b, 2001) and her associates have repeatedly demonstrated this effect, finding that memory can be "constructed" based on suggestive questions and information given after the fact. Other factors that play a role in our ability to recall information are decay and stress. Shapiro & Penrod (1986) presented evidence that suggests memory may decay over time, while other researchers have found that as stress increases, the accuracy of recall decreases (Deffenbacher, Bornstein, Penrod, & McGorty, 2004; Payne, Nadel, Allen, Thomas, & Jacobs, 2002).

Hypotheses

Given what we have learned through the literature review, our hypotheses are:

--There will be a relationship between the type of information conveyed (a misinformation effect) and the accuracy of recall about the color of the vehicle.

--Memory may decay over time.

--The level of stress will affect recall.

--There will be a relationship between the level of stress and confidence, such that confidence declines as stress rises.

Discussion

You will complete this as a part of your final project. The discussion should be written in Week 10, after all results are in. Be sure to discuss your results in relation to the information you learned in the literature review (introduction) and in relation to your hypotheses. This is the discussion section in which you will summarize the project and discuss your results in relation to the literature review and the hypotheses given
