Parallels between human and non-human animals
1) find food
2) find shelter
3) find mates
4) provide for young
5) protect ourselves
What is learning?
Learning is acquiring new information by:
- making a response
→ doing something
→ an active process
- NOT making a response (withholding)
→ not doing something
→ passive process
Formal definition of learning
An enduring change in the mechanisms of behaviour involving specific stimuli and/or responses that results from prior experience (iterations) with those or similar stimuli/responses
What is not considered learning?
Changes in behaviour can also be due to:
→ development, maturation
→ responding to a demand
→ changes in physiological bodily functions
→ reflexes (which can be modified by learning)
→ fatigue (changes in physiology)
How is learning studied ?
Experimentation
- traditionally in the laboratory (but can also be studied in the wild)
- allows for control of the environmental stimuli
- can compare behaviour between two groups (ie. Experimental group and control group)
→ control group helps rule out alternative explanations
Indications that learning has occurred
1) observing behaviour
2) compare changes between two groups
3) causation
Models of human behaviour
The “big three” of learning
1) single-event learning (habituation)
2) event-event learning (classical, Pavlovian, associative conditioning)
3) behaviour-event learning (instrumental or operant conditioning)
Single-event learning (habituation)
Event-event conditioning (classical, Pavlovian, associative conditioning)
Behaviour-event learning (instrumental or operant conditioning)
Difference between event-event learning and behaviour-event learning
→ event-event learning: organism doesn’t need to do anything in order for the next event to occur
→ behaviour-event learning: organism has to do something, which then affects the outcome it gets
Using animals in research
Three R’s
1) replacement: refers to methods that avoid or replace the use of animals in an area where animals would have otherwise been used (metanalysis, computer models, tissue culture)
2) reduce: refers to any strategy that will result from fewer animals being used (video playback instead of live demonstration)
3) refinement: refers to the modification of husbandry or experimental procedures to minimize pain and distress
Cartesian dualism
Reflexology
The study of mechanisms of reflexive behaviour
Mentalism
Studying the contents of the working mind
Empiricism vs nativism
John Locke
Believed that all ideas were acquired through experience
→ everyone starts off as a “clean slate”
Thomas Hobbes
Believed that we control voluntary behaviours but they are predictable and lawful
→ voluntary behaviours are governed by principles, these principles are regulated by hedonism (pursuit of pleasure and avoidance of pain)
Association
Simple associations combine into complex ideas
→ a connection between two events (two stimuli or a stimulus and response) such that the occurrence of one activates the representation of the other
Primary laws of association
1) contiguity: when things occur close to each other in time and space (ex. Pavlov)
2) similarity: two things shore some feature (ex. Generalization)
3) contrast: things are opposite (no modern evidence)
