PSYC 260 Lecture Notes - Lecture 13: Explicit Memory, Encoding Specificity Principle, Frontal Lobe
Document Summary
Participants were briefly presented with an array of letters and asked how many letters they could recall. Partial report: recalled 3-4 items, multiply by 3 rows, total recall would be 9-12 items. Full report: most people only recall 4 items. Decay rate: decayed from 11 to 4 letters in 1 second. We do seem to see or register more items in our sensory memory, but we simply cannot get the information out fast enough before we forget: short-term memory vs. Patient hm: shows normal short-term memory, but cannot form new long-term memories: evidence for the distinctiveness of short-term memory and long- term memory. Patient jb: shows impaired short-term memory, but have no problem forming new long-term memories. If we have to rehearse the information in the short-term memory in order to transfer it to long-term memory, how can the patient form long-term memories without having short-term memory: primacy effect. Recall advantage of first items (due to storage in long-term memory)
