    "title": "The Effect for Category Learning on Recognition Memory:\nA Signal Detection Theory Analysis",
    "subtitle": null,
    "abstract": "Previous studies have shown that category learning affects\nsubsequent recognition memory. However, questions remain\nas to how category learning affects discriminability during\nrecognition. In this three-stage study, we employed sets of\nsimulated flowers with category- and non-category-inclusion\nfeatures appearing with equal probabilities. In the learning\nstage, participants were asked to categorize flowers by\nidentifying the category-inclusion feature. Next, in the\nstudying stage, participants memorized a new set of flowers, a\nthird of which belonged to the learned category. Finally, in the\ntesting stage, participants received a recognition test with old\nand new flowers, some from the learned category, some from\na not-learned category, some from both categories, and some\nfrom neither category. We applied hierarchical Bayesian signal\ndetection theory models to recognition performance and found\nthat prior category learning affected both discriminability as\nwell as criterion bias. That is, people that learned the category\nwell, exhibited improved discriminability and a shifted bias\ntoward flowers from the learned relative to the not learned\ncategory.",
