Used Jacoby's experimental design to show evidence that information precessing is distinct for perceptual and conceptually oriented stimuli.
Like in Jacoby, study phase consisted of 3 conditions: (1) No context (COLD); (2) A context (hot-COLD) or (3) generate (hot-?). After the study 5 P took part in test phases which consisted of 1 of 5 tasks:
(1) Free recall
(2) Semantic-cued recall- (cosmos-?)- UNIVERSE
(3) Graphemic-cued recall- (unversed-?) -UNIVERSE
(4) Word-fragment completion
(5) General knowledge test- What was the Big Bang said to have created? UNIVERSE
1-3 are EXPLICIT tests of memory
4-5 are IMPLICIT tests of memory
RATIONALE: If explicit tests behave one ways and implicit another way, results within in category should be consistent. Namely, Explicit tests should be most beneficial for generate condition, then context then no context while implicit tests should be most beneficial for no context, then context and generate conditions. BUT THIS IS NOT WHAT HAPPENED
FINDINGS: Free-Recall, Gen Knowledge and Semantic-Cued recall all benefited from G-C-NC while Fragment Completion & Graphemic-Cued recall all benefited from NC-C-G. **This cuts across the implict/explicit memory distinction, suggesting processing involved isn't based on the nature of the memory (implicit vs. explicit) but on whether the memory is perceptually or conceptually based (AS TAP WOULD SUGGEST)
IMPLICATION: Former group is reliant on ceceptual processing, while latter relies on perceptual processing, so each group benefits from the same type of processing at study: generate= conceptual and NC=perceptual.
Further TAP evidence from a follow-up study (1992) found that the modality change (to auditory) only effected the perceptually-processed tests.
