Abstract

Episodic memory theories have converged on the idea that recognition memory decisions are based on global similarity computation, in which the similarity between the probe item and each memory item is computed and aggregated. Mewhort and Johns (2000) directly tested this retrieval mechanism by manipulating the feature composition of studied items and test probes -- rejection of novel items was facilitated when probes contained features not on the list even when other features strongly matched, an advantage dubbed the extralist feature effect, which greatly challenges global matching models. In this work, we conducted similar experiments using continuously-valued separable- and integral-dimen..
