Abstract
Interfering with the perceptual processing of a stimulus can improve memory. The perceptual-interference effect was investigated from the perspective of the item-specific/relational encoding distinction. This perspective suggests that perceptual interference enhances item-specific encoding but disrupts the encoding of relational and order information. The results of 6 experiments were largely consistent with this view. In Experiments 1 and 2, perceptual interference (a hypothesized item-specific manipulation) and list organization (a relational manipulation) both enhanced free recall but had opposite effects on a measure of relational processing (category clustering). Increasing list organization increased clustering, whereas perceptual interference decreased clustering. In addition, perceptual interference typically decreased memory for order. Finally, when order information was an important determinant of free recall, the perceptual-interference effect was eliminated or reversed. When reliance on order information was lessened, the perceptual-interference effect reemerged.Keywords
