identification–production distinction
a hypothesis about priming that amends the distinction commonly made for tests of implicit memory—that is, between perceptual tests that tap perceptual processing of the surface features of a stimulus and conceptual tests that tap conceptual processing of meaning or semantic information. Instead, it proposes a distinction that emphasizes different processing demands between tests that require the production of a response and those that require identification or verification regarding some property of an item. For example, word-stem completion (a perceptual test) and the category production test (a conceptual test) require, respectively, that participants produce a whole word (e.g., strong) from a word stem (e.g., str__) or produce an item (e.g., strawberry) that belongs to a given category (e.g., types of fruit). In contrast, perceptual identification (a perceptual test) and category
verification (a conceptual test) require, respectively, that participants identify a physical property of a stimulus or verify whether items are members of a given category. Also called identification–production hypothesis. See implicit memory test). [proposed by U.S. psychologist John D. E. Gabrieli and colleagues]
