Abstract

Eyewitness memory for events has been shown to be malleable and susceptible to intrusions of misinformation (Loftus & Palmer, 1974). It has been demonstrated that practicing retrieval of studied material can lead to improved recall, known as the testing effect (Karpicke & Roediger, 2008; Roediger & Karpicke, 2006). However, practiced recall may also lead to the increased incorporation of misinformation into memory, known as the reversed testing effect (Chan, Thomas, & Bulevich, 2009). While Karpicke and Roediger (2008) used Swahili-English word pairs to demonstrate the testing effect, Chan et al. used video materials. In two out of three of the Chan et al. experiments, the reversed testing effect, but not the testing effect, was found. The current study was designed to determine if testing increases susceptibility to retroactive interference using materials similar to those used in the original testing effect (Swahili-English pairs). Results indicated that the misinformation effect is increased by practicing recall. Although the testing effect was not replicated, participants who practiced recalling test stimuli showed increased susceptibility to retroactive interference.
