memory Flashcards
process of forgetting
memories disappear? or are they still there we just cant retrieve them?
evidence of “still there” (Nelson)
paired associate list
- word and number associations (67-house; 43-dog)
- subjects recalled 75% of items on the list
- out of the 25% that was forgot, if participants relearned the same association, versus one change, they were 78% more likely to remember
EX: 38-dress, 77-scissors relearned versus 38-apple, 77-kettle
what contributes to forgetting
serial position effect
- we remember first/last items better (primacy and recency)
decay theory
- memory is weakened with disuse
- hard to test ; preventing participants from rehearsal is hard
intrusions and distortions examples
car crash - asking participants how fast the car was going when they hit the other car vs when they smashed the other car
- participants recorded lower speeds when they were asked with less graphic words
false memories
2 examples:
- associated words
- narratives
Loftus
1. when presented with a list of associated words, but missing one target word (ex: tired, bed, night, dream but not sleep), participants tend to recall the non-presented item
- when asked if they remember or know the word, they report an actual memory for the item
- gave participants 4 narratives, all were true except 1 (lost in the mall); 25% reported remembering the false event
Recovered and Repressed memories
recovered memories must first be repressed, or else they are just false memories
are repressed memories valid?
flashbulb memories
events that are particularly surprising or arousing
ex: 9/11
- typically good memory for where we were, what we were doing
evidence:
- Neisser tested immediate, and 3 year later memory for Shuttle explosion
- participants were confident in their memories, but there was little agreement with the two
emotion and memory
- there is a strong relationship between the emotionality and vividness of memory
- emotional events are elss resistent to forgetting over time, but this does not mean we remember them better
