Key Terms:
Capacity - Measure of how much can be _____ in memory.
.
held
Coding
How information is changed so it can be stored in memory. Info enters the brain via senses (eyes,ears) then stored in forms such as visual, acoustic or semantic codes.
Duration
Measure of how long memory lasts before it is no longer available
______________ & ________________ found that the duration of STM was _ to __ seconds long.
How did Petersons’ test this?
Peterson and Peterson
3 - 18 seconds long.
Tested 24 students over 8 trials, gave them a consonant syllable and a 3-digit number, and asked them to recall after 3 second intervals.
Bahrick et al. tested 400 people of ages __ to __, on their memory of classmates by using a photo recognition test.
15 years after graduation, __% accurate. 48 years after graduation, __%.
17 to 74
90, 70
STM Duration Evaluation:
- Testing wasn’t ___________ because trying to memorise consonant syllables doesnt reflect ____________ memory activities.
-However we do memorise fairly useless things such as ________ numbers and-_____________, so it does have relevance to everyday life.
- Petersons’ experiment was due to _____________ instead of decay because counting numbers may “overwrite” the syllables that were ?
natural
everyday
phone
postcodes
displacement
displacement
Baddeley used lists that were acoustically and semantically the same for the test. He found that they had difficulty remembering the acoustically similar in STM but not LTM. and semantically similar words were good for STM but not for LTM
Test shows that acoustically similar words could be recalled in STM but only the meaning of the semantic list could be recalled
Coding Evaluation:
-Brandimote et al. found that people can use _________ coding in short-term memory (STM) when they’re given a _________ task, like looking at pictures, and can’t use _________ rehearsal (they were told to say ‘la la la’) before trying to remember the visuals.

Case Study - “HM”

STM to LTM
MSM is too simplified because:
