6 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

20 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

22

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

28

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
