1
Q

describe the method of the research into the duration of sensory memory

A

Sperling (1960):

  • showed p’s 3x4 grid for 50 milliseconds
  • had to immediately recall whole grid or a specific row
2
Q

describe the results into the research into the duration of sensory memory

A
  • when p’s recalled whole grid they recalled 4 -5 letters

- when recalling a row they recalled on average 3

3
Q

what was the conclusion of the research into the duration of the sensory register?

A
  • most able to recall 3 items from any row
  • therefore whole grid was held in sensory
  • couldn’t report whole grid cause the trace faded before they could finish recall
4
Q

evaluate the research into the duration of the sensory memory

A
  • lab, reliable, high internal validity

- lack ecological validity, artificial

5
Q

what is the capacity of sensory memory?

A

unlimited

6
Q

what is the duration of sensory memory?

A

less than half a second

7
Q

what is the coding of sensory memory?

A
  • modality specific (original form)
  • there is a register for each sense
  • iconic - visual
  • haptic - touch
  • echoic - sound
  • olfactory - smell
  • gustatory - taste
8
Q

describe the research into coding for sensory memory

A

Chowder (1993):

  • found echoic and iconic stores have different duration’s
  • suggests info is coded into different sensory stores
9
Q

describe the research into the capacity of sensory memory

A

Sperling (1960)

- found p’s could recall letters from a 3x4 grid when it flashed up for one 20th of a second
