    "title": "Costly Exceptions: Deviant Exemplars Reduce Category Compression",
    "subtitle": null,
    "abstract": "We investigated whether the presence of exception items can\nimpede effects of category compression (within-category items\nappearing more similar) in classification learning. We\nhypothesized that the distinct representations afforded to\nexceptions may cause the target category to appear less\ncohesive, thereby reducing the likelihood of compression\noccurring. Across two experiments, participants engaged in\nclassification learning without exceptions, with an easy\nexception, or with a difficult exception. Pairwise similarity\nratings for all items were collected before and after learning to\nindex compression. Results from Experiment 1 suggest that\ndifficult exceptions can impede compression for the contrast\ncategory when situated within its cluster, while results from\nExperiment 2 suggest that both kinds of exceptions can impair\ncompression of standard items in a target category relative to\nthe No Exception control. We also observed surprising\nevidence of a novel between-category compression effect that\nwas observed with the category structure developed for these\nexperiments.",
