Memory and forgetting
Multi-store model of memory

Proposed by Atkinson and Shiffrin ­ 1968

Incoming sensory information, Sensory memory (d=up to 4s), if attended to, STM (c=7+/-2 chunks,
d=up to 30s, encoded acoustically), if rehearsed, LTM (c=infinite, d=indefinite, encoded pictorially
and semantically)

Information flows in a linear…

Central executive: controls and monitors the other components (slave systems). Has limited storage
capacity but can process incoming auditory and visual information, enabling CE to allocate tasks to

Supporting evidence: Peterson and Peterson (1959) ­ Investigated how the passage of time affects
STM recall. Participants hear one trigram.…

Proactive interference ­ Earlier learning interferes with later learning and prevents you from
memorising that later learning.

Supporting evidence: McGeoch and MacDonald (1931) investigated retroactive interference.
Participants were divided into 4 groups. Each participant was given a list of words. After a delay
period they were given a second list…
