- Short term memory- capacity.
- Factors affecting capacity
- Reading aloud increases digit span (digits also stored in echoic store strengthens memory)
- Pronounciation (digit span less for Arabic speakers as their digits take longer to pronounce)
- Hitch: people can recall items that can be articulated in 1.5 seconds
- Miller
- Magic number= 7+/- 2
- Believed digit span is number of chunks of information (eg, chunks of three in mobile number)
- Atkinson and Shiffrin
- STM has limited capacity (forgetting is called displacement)
- Jacobs
- Digit span technique- Can recall 7 numbers
- Read aloud list of numbers/ letters, increaded lengt of lists until P's were getting it wrong. Suggested this was their digit span capacity. 5-9 digits. Age made a difference 8 years= 7 digits. 18 years= 9 digits.
