Target similarity effects: support for the parallel distributed processing assumptions

Humphreys, Michael S. and Tehan, Gerald and O'Shea, Annissa and Bolland, Scott W. (2000) Target similarity effects: support for the parallel distributed processing assumptions. Memory and Cognition, 28 (5). pp. 798-811. ISSN 0090-502X


Recent research has begun to provide support for the assumptions that memories are stored as a composite and are accessed in parallel (Tehan & Humphreys, 1998). New predictions derived from these assumptions and from the Chappell and Humphreys (1994)implementation of these assumptions were tested. In three experiments, subjects studied relatively short lists of words. Some of the lists
contained two similar targets (thief and theft) or two dissimilar targets (thief and steal) associated with the same cue (ROBBERY). As predicted, target similarity affected performance in cued recall but not free association. Contrary to predictions, two spaced presentations of a target did not improve performance
in free association. Two additional experiments confirmed and extended this finding. Several alternative explanations for the target similarity effect, which incorporate assumptions about separate representations and sequential search, are rejected. The importance of the finding that, in at least one implicit memory paradigm, repetition does not improve performance is also discussed.
