Attention System interrupt attracted by alternative stimuli (dog in street) Conscious reallocation device Attention as limited resource Attention as bottleneck Cocktail party effect : Colin Cherry Filter theory: Donald Broadbent Attenuation theory: Anne Triesman Late selection theory: Donald MacKay (pennies) Spotlight model: Michael Posner

Memory: Central to the Self
Early work of Ebbinghaus Methodology (recall, recognition, savings) Time course of loss Overlearning Serial position effect and its implications: a multi-store model of memory
10
Conclusion: a multi-store model of memory
The serial position results suggest a separation of a short term and a long term store or component of memory But there may be more!
11
Sperling: Sensory Storage (iconic memory)
Whole vs partial report Rapid decay Backward masking

Sperling exper. Whole vs Partial Report

Delay of tone--fast decay

Summary: Iconic Memory
Capacity: Very large Duration: Very short Transfer: Readout to STM Loss: Phenomenon of backward masking (and its necessity!)
21
A Multi-store model of memory
Benefits and limitations First memory: sensory store Next: Short term memory
23
Short term memory Current contents of memory
Fundamental bottleneck in processing Multiple interpretations Capacity Duration Transfer Loss
24
Basic Operations of STM
How things enter it How things stay in it. How we search for things within it. How things leave it
25
Peterson & Peterson: Decay
26
Waugh & Norman: Interference
27
Sternberg: Memory scanning
29
STM-WM (an alternative view)
Another way of looking at it (STM vs Working Memory) (Baddeley) The "bottleneck" issue and an example or two. Beating the limits--the work of Chase and Ericcsson: chunks & retrieval structures. Finally, how do things move on--elaborative rehearsal
30
Baddeley: Model of Working Memory
34
Chase, Ericcsson & Staszewski: Retrieval Structures
