Dissociation between explicit and implicit memory revealed by using the two types of testing. Implicit Memory - System or Process Initial evidence of implicit memory revealed in work on brain damaged patients. Recollective memory centered on the areas of the brain involving the temporal lobes, frontal lobes and hippocampus and diencephalon. Implicit memory also studied in normal subjects and cognitive psychologists working in this field have advocated a process approach. Squire argues that different neural structures differentiate the performance on tests tapping the two kinds of memory - explaining the dissociation found.
Explicit memory is part of declarative memory and is centered on structures in the limbic system.
Implicit memory on the procedural side is tied to the cerebellum. Damage to one area affects only one system. Implicit memory -a series of Systems which operate with common properties and rules and develop non conscious expressions of memory. Jacoby's procedure separated out the implicit or automatic learning component from the recollective. In other tests not always possible to be sure that there was no cross over between differing processes on different tests i.e. recollective memory contributing to implicit performance and vice versa.
