OUTLINE
Lecture 4: Associative Processes (+ some Memory)
Lecture Outline
FAQ/News
Matters arising from the learning labs
Memory (from Week 3)
Types of memory
Special Focus: Measuring working memory
Associative Processes
Classical conditioning
Operant conditioning
Conditioning as an adaptation
Adaptive specializations
What associations are formed in operant conditioning?
We’ll start this lecture with some topics from Chapter 3 (Memory) that were not covered
in last week’s presentation. Then, on to Associative Processes (Chapter 4)!
MIDTERM:
- multiple choice
- short answer
- choice between two essay questions
1 Types of Memory
Semantic Memory
Words, meanings, facts
Declarative memory
General facts about the world
Non-Declarative Memory
Does not depend on awareness or explicit knowledge
Believed that animals only depend on non-declarative memory
Examples:
Habituation
Perceptual priming
Classical conditioning
Procedural memory
- E.g. how to tie your shoes, play a familiar song on the piano
- Tested in rats using the radial arm maze – rat goes along the
platforms that have food and the rats need to remember which
platforms it has gone down.
4 Special Focus: Measuring Working Memory
Working Memory defined
the process of maintaining information in the short term so that it can be used in
other cognitive processes
holding it information in a short term store and using it at a later time to solve a
cognitive problem
N-Back Task
Delayed Match-to-Sample Task
White light to orient the
pigeon
Peck red light to get reward
Peck at red light to
Get a reward, the
Other light gives
No reward
Document Summary
We"ll start this lecture with some topics from chapter 3 (memory) that were not covered in last week"s presentation. Does not depend on awareness or explicit knowledge. Believed that animals only depend on non-declarative memory. E. g. how to tie your shoes, play a familiar song on the piano. Tested in rats using the radial arm maze rat goes along the platforms that have food and the rats need to remember which platforms it has gone down. Definition: process by which a previously neutral (meaningless) stimulus, through. Association with a motivationally salient stimulus, comes to elicit a response. Definition: process by which a change in behaviour occurs because the behaviour produces some consequence. This table presents the relationship between a response (a behaviour) and its outcome in operant conditioning. When a response produces a positive outcome, it"s positive reinforcement. e. g. giving a treat to a rat when it presses a lever.
