- your memory for immediate events
- SHORT-TERM MEMORY
- CODING
- STM is largely encoded acoustically
- Baddeley used lists to test semantic and acoustic similarity in LTM and STM
- participants had difficulty remembering acoustically similar works in STM but not LTM
- semantically similar words posed little problem for STM but got muddled in LTM
- CAPACITY
- measure of how much can be held in the memory
- represented in terms of bits of information, such as number of digits
- digit span
- joseph jacobs found that the average span of digits is 9.3 items and 7.3 for letters
- could be easier to recall digits as there are only a possible 9 digits whereas there are 26 possible letters
- the magic number: 7 +/- 2
- span of immediate memory is about 7, but sometimes a bit more and sometimes a bit less
- measure of how much can be held in the memory
- DURATION
- peterson and peterson
- participant given consonant syllable and three-digit number
- had to recall consonant syllable after different retention interval: 3,6,9,12,15,18
- had to count down form three-digit number during the retention interval
- 90% correct after 3 seconds
- 20% correct after 9 seconds
- 2% correct after 18 seconds
- 20% correct after 9 seconds
- 90% correct after 3 seconds
- had to count down form three-digit number during the retention interval
- had to recall consonant syllable after different retention interval: 3,6,9,12,15,18
- participant given consonant syllable and three-digit number
- STM duration is less than 18 seconds (when rehearsal is prevented)
- peterson and peterson
- CODING
- measured in seconds and minutes (short duration)
- they disappear unless they are rehearsed
- has a limited capacity of a few items or chunks and tends to be coded acoustically
- sometimes referred to as working memory
- has a limited capacity of a few items or chunks and tends to be coded acoustically
- they disappear unless they are rehearsed
- SHORT-TERM MEMORY
- the way information is changed so that it can be stored in memory
- CODING
- STM is largely encoded acoustically
- Baddeley used lists to test semantic and acoustic similarity in LTM and STM
- participants had difficulty remembering acoustically similar works in STM but not LTM
- semantically similar words posed little problem for STM but got muddled in LTM
- enters the brain via the senses and is then sorted into its various forms
- visual codes, acoustic codes (sound), semantic codes (meaning)
- CODING
