Retrieval of event files can be conceptually mediated

Abstract

Distractor-based retrieval of event files was assessed with a sequential priming experiment using a four-choice identification task. Pictures or sounds of four different animals (frog, chicken, lamb, singing bird) had to be categorized by pressing one of four keys. On each trial, a target and a distractor stimulus were presented simultaneously in different modalities. The relevant modality switched randomly between trials. Distractor repetition effects were modulated by the response relation between the prime and probe: Repeating the prime distractor in the probe produced facilitation if the response repeated, but not if a different response had to be given in the prime and probe. Repeating the prime distractor in the probe led to an automatic retrieval of the prime response. Importantly, this distractor-based response retrieval effect also emerged for those sequences in which the modality of the repeated distractor was switched between the prime and probe. This cross-modal priming effect indicates that distractors were integrated into event files on a conceptual level and that response retrieval processes were mediated by conceptual codes of the distractor stimuli.
