Memory - Cognition
Cards in this deck (7)
- 1Implicit memory= memory without awareness. Can be measured by indirect tests of intentional/incidental learning
- 2Reber (1967)Ppts learned strings of 3-8 letters. Group 1's followed an artificial grammar, group 2's were random.
Group 1 had better recall of strings and could also judge whether new strings fit the grammar, without knowing what the grammar was (implicit) - 3Experimental Dissociation= tests are affected differently by phenomenon
- 4Tulving et al (1982)Ppts learn 96 words. After 1hr they are given a word fragment completion/recognition test on 48 words.
After 1hr performance is similar but after 7 days, recognition performance is much worse - 5Multiple Memory Systems (Tulving & Schacter, 1990)Direct and indirect tests tap into different memory systems; procedural, perceptual representation, primary memory, semantic + episodic.
- 6Unitary Signal Detection Model (Berry et al, 2008)This is a computational model that generates testable predictions + promotes transparency.
A single memory strength leads to priming and recognition and receives different noise from different tasks.
Older items have stronger evidence than newer items.
Each item is associated with a single strength test value (f). This is combined with one randomly sampled noise value for each task.
f + noise = decision to whether the item is old or new - 7Transfer Appropriate Processing (Roediger et al, 1989)A given type of processing will improve performance.
Direct and indirect tests require different retrieval; indirect tests use perceptual processing and direct tests use encoded meaning of concepts.
