Multi Store Model of Memory

How do you transfer information from the short term memory to the long term memory?

• Maintenance rehearsal

• Elaborative rehearsal

• Retrieval

• Displacement

What is the capacity of the short term memory?

How is short term memory encoded?

What is the duration of the sensory memory?

What is the duration of the short term memory?

Found that the iconic sensory store has an average duration of 500 milliseconds which decreases with age. Who’s study is this?

What was Sperling’s study?

• Nonsense trigrams and counting backwards

• Recalling word lists (similar sounding words)

• Recalling word lists (semantically similar words)

• Grid of symbols

Read nonsense trigrams to participants and got them to count backwards in 3s from a large random 3 digit number for varying periods of time. Who’s study was this?

• Baddeley

• Sperling

• Peterson and Peterson

• Jacobs

Asked participants to recall 4 sets of words. The sets were similar sounds and meanings and different sounds and meanings. Whose study was this?

What did Baddeley’s STM study show?

• STM has a duration of 18-30 seconds

• STM is encoded semantically

• STM has a capacity of 7 +/-2 items

• STM is encoded acoustically
