Memory

2. Amnesics
Amnesia affects explicit long-term memory, not working memory or implicit memory.
Explicit – conscious recall of episodic information
Implicit – unconscious and automatic processing
Impaired – memory for details of one’s past, ability to form new memories.
Spared – recognition, semantic knowledge (facts), procedural memory (skills), priming.

3. 2 x 2 Designs Revisited Warrington and Weiskrantz example
Two IVs: 2 (implicit vs explicit) x 2 (amnesic vs norm)
Explicit task was to memorize 24 words & then free recall
Implicit task was to look at 24 words & then try to identify a degraded version of each of the 24 words.

These are the actual results Warrington and Weiskrantz obtained

8. Adding a Third IV 2 (test) x 2 (subj) x 2 (LOP task):
Memory test (explicit = free recall / implicit = word fragment completion)
Subject (amnesic / normal)
L.O.P. Task (graphemic = count vowels / semantic = use word in a sentence)
3 potential main effects
3 potential 2-way interactions
1 potential 3-way (higher-order) interaction.
