Implicit memory

Implicit memory

1. Perceptual and conceptual

2. Tulving showed evidence for implicit memory existence

3. TAP account: Roediger et al

   • Important distinction is not between I&E retrieval from different stores, but the match between P or C processing engaged during testing
     • C/P tests benefit most from encoding that engaged similar processes
   • Contradictions
     • Hunt: orthographic distinctiveness (perceptual factor) affected both perceptual IM performance and free recall (explicit conceptual task)
     • McDermott and Roediger: presenting words conceptually related to targets enhanced free recall (explicit conceptual) of targets but not category exemplar tests (implicit conceptual)
     • To deal with problems, modified TAP account: components of processing
       • Performance involves sets of processes
         • Criticised for being too circular

4. Memory systems accounts

   • Both Tulving and Squire's have been applied to account for differences observed between E&I memory performance
     • Regarded as being due to the tests taxing different memory systems
       • Squire
         • E: uses declarative memory I: uses procedural memory
       • Tulving
         • IP: use 'perceptual representation system
         • IC: conceptual representation systems (Gabrielli)
