1 Memory Psychology 3926

2 Introduction Skinner vs. the cognitivists
Cognition won, because it explains more data 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’ve mentioned. Not just in Canada, but there was a huge Canadian component

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

5 Key terms and method Working memory Reference 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 Surprise Chunking RI and PI context
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
CN PJ MJ SJ storing 1 2 3 4 Hp vol Cache Maze Sp DNMTS Colour DNMTS

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
