Forms of Memory for Representation of Visual Objects
Abstract
This research examined the relation between implicit and explicit memory for novel visual objects. Implicit memory was assessed with an object decision task in which previously studied and nonstudied objects were flashed briefly and subjects decided whether they were structurally possible or impossible; implicit memory was indicated by more accurate object decision performance for studied than nonstudied objects (a) priming off ect). Explicit memory was assessed with a standard yes/no recognition task. Results of several experiments revealed: a) priming for possible but not impossible objects across a range of conditions and materials; (b) invariance of priming across study/test changes of object size and reflection that impaired recognition; (c) enhancement of recognition but not priming by functional encoding tasks ; and (d) preservation of object priming in amnesic patients with explicit memory deficits. Results suggest that priming is mediated by a presemantic structural description system that is independent of episodic memory. Implicit memory, Priming, Object decision, Structural description.
