A01 - Short Term Memory

What is the capacity of STM? This is based on Miller's idea that…?

7±2 items

Many things come in groups of 7 like the days of the week

Miller suggested we are _________ to remembering this quantity and that a ‘________’ method can _________

Predisposed

Chunking

Help us recall more

What does ‘chunking’ involve?

Making a connection to remember more at one time

Who carried out the digit span test to also establish the capacity of STM?

Jacobs

The digit span test involved presenting…

A sequence of digits to a person they could recall them aloud in order

What happens to the sequence of digits after each response?

The length increases

What was the mean letter and digit span (amount remembered)?

7.3

9.3

The duration of STM is _________ as demonstrated by ____________

18 to 30 seconds

Peterson and Peterson

What did P + P find in 24 undergraduates?

Recalling consonant syllables while counting down from a 3 digit number decreases accuracy over time

What did counting down from the 3 digit number prevent?

Mental rehearsal of the consonant syllables

How is STM coded/processed?

Acoustically

Who demonstrated the different coding in STM and LTM?

Baddeley

In Baddeley's experiment, he found mistakes were made by participants when…

Recalling acoustically-similar words straight after learning them (STM recall)
