- The Multi-store model of memory
- Sensory memory
- Several stores called sensory registers. Echoic- sound, iconic- visual, olfactory- smell, haptic- touch, gustatory - taste
- Capacity - quite large. Sperling gave participants a grid of 12 letters. They remembered 4.5/12 letters
- Duration: depends on the register. Information in the iconic register lasts for 0.5 seconds.
- Encoding: stored in its raw, unprocessed form.
- Short-term memory
- Capacity of short-term memory: Jacobs. used a digit span technique, increased numbers in a sequence by 1 every time. Participants recalled between 5 and 9 items.
- Capacity of STM: Miller. Suggested that the STM does have a limited capacity and it is between 7+/-2 chunks.
- Duration of STM: up to 30 seconds. Peterson and Peterson gave participants trigrams, then they had to count back in 3's.When the delay time was short participants recalled 80% of information, After an 18 second interval recall was 10%
- Encoding in the STM: information is encoded and retained via an acoustic code, we repeat information verbally to ourselves. Conrad found that similar words were recalled less well than dissimilar sounding words
- Long-term memory
- Capacity of the LTM: seen as being unlimited
- Duration of LTM: indefinite. Bahrick et al- yearbook photos of classmates
- Encoding in the LTM: semantic
- Sensory memory
