PSYC 108 Lecture Notes - Lecture 9: Frontal Lobe, Short-Term Memory
Document Summary
Working memory: baddeley"s theory of wm, phonological system. Left lateral frontal lobe: deals with sounds, use a rehearsal system to keep it in mind, based on sub-vocal articulation. Shows this by using articulatory suppression procedure: people"s memory was worse, phonological similarity effect, phonemes that don"t sound similar are easier to remember. Short term memory depends on an acoustic code: visual system, right lateral lobe, corsi block task. Sketch pad: touch blocks in same order (haptic code, rehearsal here may depend on eyes, cowan"s theory, wm is activated ltm. Lateral prefrontal cortex: ventrolateral pfc (vlpfc, dorsolateral pfc (dlpfc) Important for working memory: experiment, a not b test, with dlpfc lesioned in monkeys, they make the error.
