  1. Memory Psychology 3906

  2. Introduction • Skinner vs. the cognitivists • Cognition FTW • However, we still use the methods of course • The study of animal cognition and memory started in the mid 70s

  3. The Dalhousie conferences • Conferences in the 70s, as I mentioned the other day • Not just in Canada, but there was a huge Canadian component

  4. Cheng Sherry Revusky Staddon Spetch Shettleworth Honig Baker Grant Wilkie Hogan Lolordo Wiesman Roberts We rule

  5. Key terms and method • Working memory • What you need to complete a sinlge trial of some task • Reference memory • The rules of the game, the requirements for any trial of a task

  6. Matching to sample

  7. Matching to sample • MTS can be DMTS • Or you can have delayed non matching to sample • Or symbolic matching to sample • Stimuli can be colours, or shapes or spatial locations

  8. The Radial Maze • Olton and Samuelson (1976) • Working and reference memory errors • Also used with many different species • Might relate to foraging in some species • Food is information, not reinforcement

  9. Conditions • Salience • ITI and duration play a role here • Surprise • Chunking • RI and PI • context

  10. Species differences • First off, the lowly pigeon has one hell of a memory for individual slides • Al Kamil and Russ Balda have found amazing long term memory in corvids • Anders Brodin has found long lasting cache memory in parids • Are differences specific or general?

  11. Food storers on different tasks

  12. Contents of memory • Retrospective vs. prospective encoding • Roitblat 1980 • Symbolic matching • 1) Red sample -> Horizontal line • 2) Orange Sample -> Vertical line • 3) Blue Sample -> Almost vertical line • If they make mistakes when the choices are 1 and 2, they are encoding retrospectively • If they do when the choices are 2 and 3, they are encoding prospectively

  13. contents • Directed forgetting • Metamemory • Implicit vs explicit memory

  14. In sum • We are scratching the surface • Don’t try to get inside an animal’s head • New cool stuff all the time
