Abstract

Removing information from working memory is thought to free up capacity and improve the retention of other information. However, whether this benefit arises from reducing interference from the to-be-forgotten information or from freeing up cognitive resources remains unclear. We examined this by comparing removal immediately following encoding an item (immediate removal), or delayed until after other items have been encoded (delayed removal). Interference theories predict that both types of removal should reduce interference and improve memory performance. In contrast, if removal frees up cognitive resources, the beneficial effect on memory should be greater the earlier it occurs, as the resources can then be allocated to subsequently encoded items. Experiment 1 showed that both immediate and delayed removal failed to reduce interference from the to-be-forgotten items but improved memory for item-location bindings of other items still maintained in working memory. In Experiment 2, removal only facilitated item-location bindings for items encoded afterward. These results suggest that removal frees up working memory capacity by increasing available resources rather than by reducing interference.

期刊介绍： Cognition is an international journal that publishes theoretical and experimental papers on the study of the mind. It covers a wide variety of subjects concerning all the different aspects of cognition, ranging from biological and experimental studies to formal analysis. Contributions from the fields of psychology, neuroscience, linguistics, computer science, mathematics, ethology and philosophy are welcome in this journal provided that they have some bearing on the functioning of the mind. In addition, the journal serves as a forum for discussion of social and political aspects of cognitive science.
