Coding, Capacity, Duration Flashcards
What are the 2 types of memory ?
Short term = picks up information from surroundings but doesn’t acknowledge it unless its rehursed
Long term = permanent store holding unlimited amounts of info for long periods of time
What is capacity
The amount of information that can be held in memory
What is coding
format in which information is stored in the various memory stores
^ process of converting information from one format to another
What is duration
Length of time info can be held in memory
What is the study on coding
Baddeley
Split participants into 4 groups of acoustically similar/dissimilar words and the same for semantic
^ LTM is semantically coded and STM is acoustically coded
What is the study on capacity
Jacobs
Developed digit span - string of numbers
STM has limited capactiy of 5-9 items LTM is unlimited
What is the study on duration
Peterson and Peterson
undergrad students took part in 8 trials in a lab. On each trial student was given a constanant syllable.
Interference task - also given a 3 digit number to count down from. Told to stop at different times on the trial
Shows when rehersal is limited very little stays in the STM for longer than 18 seconds. Overall between 18-30 seconds
