Q

what is the duration and capacity of the sensory memory?

how does it encode information?

A
  • duration = 1/2 a second up to several seconds at maximum
  • capacity = between 12 and 16 items (large)
  • encoding = using all 5 senses (also known as modalities)

Q

what is the:
- iconic
- haptic
- echoic
memory?

A
  • iconic = visual information from eyes / light
    things you see
    stores as images
  • haptic = tactile information from touch
    stores as feelings
  • echoic = auditory input from the ears
    things you hear
    stored as sounds
  • stored in the same form as the senses
