Abstract
The main aim of the present study was to study memory interference using a more ecological approach, where competing events can be separated by the environmental context. In order to increase the ecological validity of the study, context was manipulated through the presentation of video clips instead of commonly used static pictures. The second aim of the study was to assess if the contextual cues could be used to resolve memory competition. Twenty-five participants partook in a memory task (AB/AC vs. DE), where competition between AB and AC items was established by associating some word cues (A) with two associates (B/C) compared to control condition, where each word cue (D) was associated with only one associate (E). Additionally, videos... (More)

Additionally, videos were presented along with the word pairs and participants were asked to associate each context video with the word-pair. In a later memory test, participants were asked to retrieve the word pair in the presence and absence of contextual cues. Critically, the behavioral and ERP results revealed an interference effect, even if the competing events were presented in different environmental contexts. The interference effect was similar in the presence and absence of the contextual cues, which
indicates that our context manipulation was not helpful in resolving interference. This was evident both behaviorally and in the ERP analysis. The contextual cues may have been too non-specific for resolving the interference sufficiently. (Less)
