Semantic-to-autobiographical memory priming: the role of cue repetition.

It is now well established that general information processing causes the activation of memories in the autobiographical memory system, and these memories on occasion emerge as involuntary autobiographical memories. This priming phenomenon has been dubbed semantic-to-autobiographical memory priming, and our goal in the current study was to examine the effects of cue/prime repetition on the production of involuntary autobiographical memories that were primed with semantic stimuli. In three experiments, participants were primed with words (e.g., cat), and then they were given an involuntary memory task (the vigilance task), which contained cues related to the primed stimuli. In Experiment 1, the cues were phrases containing the primes (e.g., getting a cat), which were presented one or five times. In Experiment 2, the cues were also phrases containing the primes (e.g., getting a cat), but they changed their context (e.g., feeding a cat), every time they repeated in the five-presentation condition. Experiment 3 also presented the cues one or five times, but the cues were replicas of the primes (e.g., cat). Consistent with predictions, greater priming was found in the five-presentation cue conditions in all three experiments, and Experiment 3 failed to find priming in the one-presentation cue condition, also consistent with predictions. We explain the findings in terms of semantic-to-autobiographical memory priming theory, and also argue that the results help explain the production of involuntary memories in everyday life.
