What are memory researchers interested in?

  1. The types of things our memory can hold (ie. how is info coded/held and stored)

  2. The limiting factors of memory (capacity and duration)

  3. The process that allows information to enter and exit memory (ie. how we encode, store and retrieve info)

2
New cards

Define encode. 

The process of putting things into our memory. 

3
New cards

Define code.

CHECK VIDEO.

New cards

Like attention, is memory a unitary system? Why?

No. 

Because we have short-term storage memory and long-term memory storage, indicating the separate components of memory.

Explain the Atkinson-Shiffrin Multi-Store (modal) Model

  1. Sensory Input

  • you receive sensory input

  1. Sensory Memory

  • memory store number 1 where memory is held for the shortest amount of time

  • unattended information is lost

  1. Short-term Memory

  • memory store number 2 where memory is held for medium time because attention is required for information to get to this stage

  • unrehearsed information is lost

  1. Long-term Memory

  • memory store number 3 holds memory for the longest time because encoding has occurred in order for information to get to this stage

  • some information may be lost over time

Define sensory memory.

A limited capacity store that holds basic sensory information for a very limited amount of time.

What are the different stores for each of our senses?
