  1. Experimental PsychologyPSY 433 Chapter 10 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.

  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.
