week 6 Flashcards
sensory memory (SM)
to create coherent perception
- very brief
persistence of vision
the continued perception of a visual stimulus after it is no longer present
sperling’s experiment
- whole report method: report as many letter that were shown (4,5/12)
- partial report method: letter in a single 4 letter row and high, medium and low pitched noise after the letters were shown (3,3/4)
- delayed partial report method: same as before, but with a delayed tone (1/4)
–> conclusion: SM registers almost of the information but decays
ionic memory/visual icon
brief sensory memory for visual stimuli
echoic memory
the persistence of sound
short term memory (STM)
stores small amount for a brief period (4-7 items)
digit span
the number of digits a person can remember
change detection
determine what has changed between 2 pictures
chunking
small units –> larger meaningful units
–> increases our ability to hold information in the STM
semantic code
based on one word in chunking
long term memory (LTM)
- a network that links concepts in memory
- retrieving one thing –> triggers other
- some connections are stronger than others
- incomplete retrieval –> if you can not access a concept but retrieve others (tip-of-the-tongue)
declaritive (explicit)
memories that can be consciously accessed and be declared
- episodic
- semantic
non-declaritive (implicit)
memories that cannot be consciously accessed
- procedural: skills
- perceptual representation system: perceptual priming
- classical conditioning
- non-associative learning: habituation sensitization
amnesia
memory loss
anterograde amnesia
inability to form new memories
