Stimulus
Event that happens to you
Response
Something you do voluntarily
What is learning?
Process of acquiring new knowledge or persistent change in behaviour as a result of experience
Not all behaviour is learned
Some = innate/evolved; adaptive for dealing with fixed environment features
Example of innate behaviour
Stickleback fish responds to stimulus least close to a fish
Hard wired S-R links
Sign stimulus elicits response; mental link through evolution
Supernormal stimuli
More effective than naturally occurring sign stimuli
Mental representations
Mental state accompanying stimulus experience, e.g., round object triggers egg rolling response
Unlearned behaviour
Preprogrammed responses to constant environmental aspects increase survival
Learning throughout life
Persistent behaviour change due to experience, necessary to adapt to environment
Habituation
Reduction in stimulus response due to repeated exposure
Types of habituation
ST habituation = response doesn't recover after delay; LT habituation = response does recover
Classical conditioning
Predicting; learned CR = involuntary
Instrumental conditioning
Controlling events; response only predicts stimulus if animal responds
Omission training
Keylight CS predicts food but conditioned peck cancels it
Control of experience
Can control response production but not make animal do it
Override of conditioned response
Bird can override classically conditioned response with voluntary instrumental one to get food
Fixed action pattern
Stereotyped response due to sign stimulus
Preexisting link
Between stimulus and response becomes less effective with habituation
Adaptive behaviour
Behaviour that helps in dealing with fixed environment features
Experience adaptation
Most environments are not constant, so adaptation occurs throughout lifetimes
