  • Output Interference in Recognition Memory

    Psychological Science and Review.

    Theories of why humans forget have been challenged by the newly discovered list-length/output-interference paradox, in which—under certain testing conditions—learning is not harmed by the amount of verbal material studied, whereas retrieval of that material becomes more difficult with increases in the number of items tested. The latter finding is known as output interference, and the results of the experiment reported here indicate that a release from output interference is obtained when the…

    Theories of why humans forget have been challenged by the newly discovered list-length/output-interference paradox, in which—under certain testing conditions—learning is not harmed by the amount of verbal material studied, whereas retrieval of that material becomes more difficult with increases in the number of items tested. The latter finding is known as output interference, and the results of the experiment reported here indicate that a release from output interference is obtained when the nature of the items is changed during testing. Specifically, when participants are asked to recognize items from two categories, output interference is minimized when items from each category are tested separately in large blocks. This finding supports models of forgetting that assume interference arises from information about the to-be-learned material that is stored in memory; in contrast, this finding is difficult to explain using models that assume forgetting is the result only of changing context.

  • Simultaneous Cross-Situational Learning of Category and Object Names

    Proceedings of the 31st Conference of the Cognitive Science Society

    Previous research shows that people can acquire an impressive number of word-referent pairs after viewing a series of ambiguous trials by accumulating co-occurrence statistics (e.g., Yu & Smith, 2007). The present study extends the cross-situational word learning paradigm, which has primarily been used to investigate the acquisition of 1-to-1 word-referent mappings, and shows that humans can concurrently acquire both 1-to-1 and 1-to-many mappings (i.e., a category relation), even when the many…

    Previous research shows that people can acquire an impressive number of word-referent pairs after viewing a series of ambiguous trials by accumulating co-occurrence statistics (e.g., Yu & Smith, 2007). The present study extends the cross-situational word learning paradigm, which has primarily been used to investigate the acquisition of 1-to-1 word-referent mappings, and shows that humans can concurrently acquire both 1-to-1 and 1-to-many mappings (i.e., a category relation), even when the many referents of a single word have no unifying perceptual features. Thus, humans demonstrate an impressive ability to simultaneously apprehend hierarchical regularities in their environment.
