Term
Classical conditioning
Definition
Form of learning based on the repeated association of two different stimuli
Term
Ivan Pavlov
Definition
Theorist behind Classical conditioning, famous for his experiment with the digestion of dogs
Term
Stimulus
Definition
And even that elicits a response from an organism
Term
Response
Definition
A reaction by an organism to a stimulus
Term
Unconditioned stimulus (UCS)
Definition
Any stimulus that consistently produces a particular, naturally occurring, automatic response.
Term
Unconditioned response (UCR)
Definition
The response that occurs automatically when the UCS is presented
Term
Conditioned stimulus (CS)
Definition
Through repeated association with the UCS, triggers a very similiar response to the UCR
Term
Association
Definition
Refers to the linking of pairing of two different stimuli
Term
Conditioned response (CR)
Definition
The learned response that is produced by the CS after the association has been made.
Term
Neutral stimulus (NS)
Definition
The stimulus that will not produce the UCR before learning
Term
Acquisition (CC)
Definition
The overall process during which an organism learns to associate the two events (CS and UCS)
Term
Extinction (CC)
Definition
The gradual decrease in the strength or rate of a CR that occurs when the UCS is no longer presented
Term
Spontaneous recovery (CC)
Definition
The reappearance of a CR when the CS is presented following a rest period
Term
Stimulus generalisation (CC)
Definition
The tendency for another stimulus similiar to the Cs, to produce a response that is similiar to the CR.
Term
Stimulus discrimination (CC)
Definition
Occurs when an organism responds to the CS, but not to any other stimulus that is similiar.
Term
Graduated exposure
Definition
Involves presenting successive approximations of the CS until the CS does not produce the conditioned response
Term
Flooding
Definition
Involves bringing the client into direct contact with the anxiety-producing stimulus till the conditioned response is extinguished
Term
Aversion therapy
Definition
Form of behaviour therapy that involves CC processes to discourage undesirable behaviour by associating it with an unpleasant stimulus
Term
Trial and Error learning
Definition
Learning by trying alternative possibilities until the desired outcome is achieved
Term
Edward Thorndike
Definition
Studying animal intelligence and proposed the learning theory of trial and error
Term
Law of effect
Definition
States that a behaviour that is accompanied by satisfying consequences is more likely to recur
Term
Instrumental learning
Definition
Refers to the process through which an organism learns the association between behaviour and its consequences
Term
Operant conditioning
Definition
Based on law of effect, an organism will tend to repeat a behaviour that has desirable consequences
Term
Operant
Definition
A response that occurs and acts on the environment to produce some kind of effect
Term
Three-phase model
Definition
The stimulus(S) --> Response(R)--> Consequence (C)
Term
Burrhus Skinner
Definition
Inspired by Thorndike, experimented on rats to coin the theory of Operant conditioning
Term
Reinforcer
Definition
Any stimulus that strengthens or increases the desired behaviour
Term
Schedule of reinforcement
Definition
A program for giving reinforcement, specifically the frequency and manner in which a desired response is reinforced
Term
Continuous reinforcement
Definition
When the reinforcer is provided immediately after every correct response
Term
Partial reinforcement
Definition
The process of reinforcing some correct responses but not all of them
Term
Fixed-ratio schedule
Definition
When the reinforcer is given after a set number of desired responses have been made
Term
Variable-ratio schedule
Definition
When the reinforcer is given after an unpredictable number of correct responses
Term
Fixed-interval schedule
Definition
Involves the delivery of reinforcers after a specific period of time after previous reinforcer, provided the correct response has been made
Term
Variable-interval schedule
Definition
When reinforcment is given after irregular periods of time has passed, provided the correct response has been made
Term
Positive reinforcement
Definition
The presentation of a pleasant stimulus following a desired response, thereby strengthening a response
Term
Negative reinforcement
Definition
The removal or avoidance of an unpleasant stimulus to increase or strengthen the desired behaviour
Term
Positive punishment
Definition
Involves the presentation of a stimulus and thereby decreasing the likelihood of a response occuring again
Term
Negative punishment
Definition
Involves the removal of a pleasant stimulus and thereby decreasing the undesired behaviour
Term
Response cost
Definition
Involving any valued stimulus, whether or not it caused the behaviour, being removed as an act of punishment
Term
Acquisition (OC)
Definition
The establishment of a response through reinforcement
Term
Extinction (OC)
Definition
The gradual decrease in the strength of a learned response following consistent non-reinforcement of the response
Term
Spontaneous recovery (OC)
Definition
The organism will once again show the response in the absence of any reinforcement after a rest period
Term
Stimulus generalisation (OC)
Definition
Occurs when the correct response is made to another stimulus that is similiar to the conditioned response that was reinforced
Term
Stimulus discrimination (OC)
Definition
Occurs when an organism performs the correct response to the stimulus and is reinforced, and not to any other similiar stimuli
Term
Shaping
Definition
A procedure in which a reinforcer is given for any response that successively approximates and leads to the desired response
Term
Token economies
Definition
Settings in which an individual receives tokens(reinforcers) for desired behaviour and these tokens can be exchanged for 'real' rewards
Term
One-trial learning
Definition
Type of learning involving a relatively permanent change in behaviour that occurs as a result of one experience only
Term
John Garcia
Definition
Experimented on rats with saccharine flavoured water to test his theory of one-trial learning
Term
Taste aversion
Definition
A conditioned response that results from a person or animal establishing an association between a particular food and feeling ill
Term
Observational learning
Definition
Occurs when someone uses observation of another person's actions and their consequences to guide their future actions
Term
Modelling
Definition
Another name for observational learning
Term
Albert Bandura
Definition
Famous for his experiment with Bobo dolls and proposing the learning theory of Observational learning
Term
Vicarious conditioning
Definition
The individual watches another person displaying the behaviour that is reinforced or punished and then behaves in the same or a modified way
Term
Vicarious reinforcement
Definition
Increases the likelihood of the observer behaving in a similiar way to the model whose behaviour is reinforced
Term
Vicarious punishment
Definition
Occurs when the likelihoodof an observer performing a particular behaviour decreases after having seen a model's behaviour being punished
Term
Attention
Definition
In order to learn through observation, we must closely watch the model's behaviour
Term
Retention
Definition
Having observed the model ,we must be able to remember the model's behaviour
Term
Reproduction
Definition
We must have the ability to put into practice what was observed to be able to imitate it
Term
Motivation-Reinforcement
Definition
Learner must want to perform the behaviour through reinforcement
Term
External reinforcement
Definition
If an individual receives a reinforcer, her motivation will be influenced in a positive way
Term
Self reinforcement
Definition
When we are reinforced by meeting certain standards of performance we set for ourselves
Term
Insight learning
Definition
Type of learning involving a period of mental manipulation of information associated with a problem, prior to the realisation of a solution to the problem
Term
Wolfgang Kohler
Definition
Famous for his experiment with chimpanzees and proposing the theory of insight learning
Term
Preparation
Definition
First stage of insight learning, the person will gather as much information as possible about what needs to be done
Term
Incubation
Definition
Second stage of insight learning, period of 'mental time out' during which the information is put aside
Term
Insightful experience
Definition
The 'ah-ha!' moment, a mental event that unexpectedly bridges the gap between the problem and its solution in a 'flash'
Term
Verification
Definition
The final stage of insight learning, the visual solution that flashed into mind is acted upon and tested
Term
Latent learning
Definition
Learning that occurs without any direct reinforcement but remains unexpressed or hidden until needed
Term
Edward Tolman
Definition
Conducted the experiment's with the rat maze and goal box, famous for latent learning
Term
Learning cognitive map
Definition
A mental representation of the relationship between locations
