PSYC 105 Lecture Notes - Lecture 3: Change Blindness, Change Detection, Fluid And Crystallized Intelligence
Document Summary
Memory, patient hm, had both hippocampi removed, had only working memory - no long term memory, could not encode new long term memory. Shows that people actually remember all 12, but they forget over time: must play tone within . 2 seconds, fades quickly, experiment says this must be its own type of memory - sensory memory, also called iconic memory. Takes effort: different type of short-term memory for different types of memories, not hard to remember digits while doing a color changing ask because they are different types of memory. Showed a double dissociation between visual and spatial memory: miller, 7 plus or minus 2, doesn"t matter how complex the items are. Remember all the words: n-back task, remember what came before, these working memory tasks correlate with intelligence, they predict a huge range of things. Study says yes, fluid intelligence improved from training on working memory: high capacity working memory people have more efficient memory.
