IM & Amnesia

IM & Amnesia

1. Graf (1984)

   • Asked p's to judge how much they liked each word in a list. 3 EM tests: free recall, cued recall, recognition test. 1 IM test: word-stem completion
     • Amnesiacs showed poor performance on E tests but not on I tests

2. Vaidya (1995)

   • No difference between amnesiacs and controls in either perceptual IM memory performance or conceptual IM performance
   • Poor performance observed with E perceptual and conceptual tests

3. Findings conflict with TAP. According to TAP, amnesiacs able to perform IM tests because they retain perceptual processing ability

4. Cermak (1995)

   • Explained findings in terms of dual-memory processes (Mandler)
     • Amnesiacs will exhibit normal memory performance when memory task can be accomplished on the basis of item-familiarity processing fluency
     • Implicit/perceptual tasks can be accomplished on this basis. Explicit/conceptual tasks require more context-based discriminations
