Chapter 5 - Learning Flashcards
What is the definition of learning?
A relatively permanent change in behaviour, knowledge, capability, or attitude that is acquired through experience. Can’t be attributed to illness, injury or maturation
What do behaviorist’s focus on in learning?
The study of observable behaviour
What do cognitive psychologists suggest about learning?
People choose whether or not to imitate observed behaviours
What are the two types of learning?
1) Classical conditioning
2) Operant conditioning
What is classical conditioning?
Learning by association (associate one event with another)
What was Ivan Pavlov’s contribution to the study of learning?
- Discovered classical conditioning with his experiments with dogs
- awarded Nobel Peace prize
- he happened upon principles of conditioning while studying salivation in dogs
What are the principles of classical conditioning?
1) stimulus
2) neutral stimulus
3) unconditioned stimulus
4) conditioned stimulus
5) unconditioned response
6) conditioned response
What is a stimulus?
Any event or object in the environment to which an organism responds
What is a neutral stimulus?
Any stimulus that fails to get a natural response
What is the orienting reflex?
An unlearned response in which an organism attends to a stimulus
What is an unconditioned stimulus?
Any stimulus that gets a response from an organism naturally
E.g. dog salivating in response to food
What is an unconditioned response?
An unlearned response to an unconditioned stimulus
E.g. smells or sees food and salivates
What is a conditioned stimulus?
Previously neutral stimulus that elicits a conditioned response because it has been paired repeatedly with the stimulus the naturally elicits that response
What is extinction?
Occurs when the conditioned stimulus is repeatedly presented without the unconditioned stimulus
E.g. dog stops doing trick when you stop rewarding
What is spontaneous recovery?
Sometimes occurs when, after extinction, the conditioned stimulus is presented and the conditioned response reappears (Generally weaker and shorter in duration)
What is generalization?
Occurs when the stimulus, similar to the conditioned stimulus, elicits the conditioned response
E.g. similar noise, colours
What is discrimination?
Occurs when the conditioned response is made only to the conditioned stimulus and not to any other similar stimuli
E.g. not a b-note, not a d-note.. only a c-note
What was John B. Watson’s contribution to classical conditioning?
Said humans are shaped solely by environment
Leader of revolutionary movement in psychology called Behaviorism
Who is known as the father of behaviorism?
John B. Watson
What did John B. Watson discover to be the phases of conditioning fear with Little Albert?
1) no fear of white rat initially
2) fear of loud noise
3) white rat and noise together
4) association of loud noise, which caused fear of white rat
5) fear of white rat alone
Who carried on John B. Watsons work?
Mary Cover Jones
What are the factors influencing classical conditioning?
1) # of pairing of the conditioned stimulus and the unconditioned stimulus
2) intensity of the unconditioned stimulus
3) how reliably the conditioned stimulus predicts the unconditioned stimulus (all the time or just sometimes)
4) temporal relationship between the conditioned stimulus and the unconditioned stimulus (how frequently/quickly you present reward)
What are examples of classical conditioning in everyday life?
1) taste aversion
2) fears and phobias
3) superstitions
4) drug use and tolerance
Who is seen as a great authority on operant conditioning?
B. F. Skinner
What did B.F. Skinner discover about operant conditioning?
Useful in conditioning complex behaviours.
It’s a form of learning in which the consequences of behaviour are manipulated, this either increases or decreases the frequency of a response, or can shape an entirely new set of responses
What is reinforcement?
Occurs when a behaviour is repeated because of the consequence that followed it
What is positive reinforcement?
Involves adding a pleasant consequence to an action to increase the probability of the action being continued
(Praise, prize)
What is negative reinforcement?
Involves the removal of something unpleasant and results in the increase of the probability of the action occurring again (taking excedrin and Pepsi for a headache)
What is a reinforcer?
Anything that follows a response that increases the likelihood that the responsible occur again in the future
What is higher order conditioning?
This occurs when a previously neutral stimulus becomes a conditioned stimulus
What was the operant chamber called designed by Skinner?
The “Skinner Box”
