The Context Repetition Effect: Role of prediction in new memory formation.

3rd Place at Denman Undergraduate Research ForumMany theories posit that the associative process at the core of episodic memory binds the content of an experience to the context in which we experience it. Here, context can be broadly defined as the mental representation capturing our recent experience. We recently discovered the context repetition effect (CRE), which shows that repeating a context once leads to greater memory performance for an item learned within that context even if the item does not occur again. Currently, we have conducted three studies to test the CRE. Experiment 1 was a complete replication of the original experiment that first discovered the CRE, save that there were multiple repetitions of a context instead of just one. We found that the presentation of a context and item, followed by two repetitions of the context with a new item each time, resulted in a near significant boost in memory and confidence in memory of subjects for the original item. Experiment 2 replaced words with scenes and faces. Subjects associated male and female faces with indoor and outdoor scenes. Subjects showed trends towards reduced performance and no demonstration of the CRE. Lack of power for performance results possibly due to difficulty in encoding faces relative to words. Experiment 3 replicated Experiment 2, save that there was an additional repetition. Results trended toward those found in Experiment 2.No embargoAcademic Major: Psycholog
