Memory: Atkinson and Shiffrin - The multi-store model of memory.
Memory consists of a number of separate stores and that memory processes are sequential.

Sensory memory: register sensory information. 1-3 seconds. Modality specific. Only small mount transferred into short-term memory store.

STM: Limited capacity and duration, 6-12 seconds.
If rehearsed goes to LTM, if not it's lost.

LTM: believed to be indefinite duration, unlimited capacity.

Glanzer and Cunitz:
Aim: Investigate recency effect in free recall.
Procedure: Lab, participants heard a list of items, but right after recall it.
Result: Recalled words from beginning, and the end. U-shaped curve.

Amnesia = no new memories, H.M
Support multi-stored memory
Very simple, LTM maybe serveral

Baddeley and Hitch - The working memory model
STM is unitary and passive information processing

The central executive: Controlling system, monitors and coordinates operations of other components. Limited capacity.

the episodic buffer: Limied-capacity, conscious awareness, episodic memory.

The phological loop: Verbal and auditory information. Inner voice and inner ear.

the visuo-spatial sketchpad: Inner eye.

Baddeley and Hitch: Paricipants answer more and more questions about simple letter combinations that were shown the same time. Reaction time increased = more difficult.
Finding: No significant difference in reaction time between the group who were asked to repeat the or two numbers from 1-6. But group with repeat random numbers did worse.
Overload problems for the central executive.
Which part linked to underlying memory problems.
Unclear role of central executive.

Compare: serveral stores STM temporary., sensory, rehersal, short term memory = before long term, limited duration and capacity.
Contrast: Entire memory system vs STM
Simple STM vs. Complex
