Psychology of Learning Flashcards
What is classical conditioning?
It is when we associate two or more things together and anticipate a particular outcome. There are a series of stimuli which allows us to catagorise behaviour and responses.
Describe pavlov’s experiment…
- Classical conditioning was discovered by accident when research was being conducted into the digestive system of dogs.
- During the research, it was noted that when the dog heard the lab assistants approaching to feed them, they started to salivate.
- A series of controlled experiments were set up, with the aim of conditioning
What is the UCS, NS, CS, UCR, CR
Uncontrolled Stimulus
Neutral Stimulus
Conditioned Stimulus
Unconditioned Response
Conditioned Response
What is acquisition in classical condition?
The overall process during which the organism learns to associate two events.
This is the process of the unconditioned stimulus and the neutral stimulus pairing.
What is performance in classical conditioning?
It is when the UCS is no longer required for the the CR to occur, this is known as performance.
With Pavlov’s, this was when the dog salivated as the sound of the bell, without the food being present.
What is contiguity in classical conditioning?
The timing of the stimulus being presented in order for the conditioning to occur.
It is the time between the NS and UCS is crucial to get right, otherwise the conditioning will not occur.
The UCS and NS need to be presented extremely close to each other.
Time needs to be rapid to ensure the pairing occurs.
What is contingency in classical conditioning?
The relationship between the stimulus and expectation that one comes with the other.
Contingency is the expectation that the CS will follow.
This occurs after the conditioning has occurred - think of the dogs waiting for food after the ding.
The expectation is contingency.
What is stimulus generalisation?
The spread of effects of conditioning to stimuli that differ in certain aspects from the stimulus present during original conditioning.
If the response is similar to the presence of the original stimulus, generalisation has occurred.
What is stimulus discrimination?
The ability to distinguish among different stimuli and to respond differently to them.
What is an example of stimulus discrimination
The child only reacts to when a red balloon pops, not all colours of balloons.
What is an example of stimulus generalisation?
A small dog bit a kid, so they are afraid of all dogs.
What is extinction?
A process in which the pairing of the stimulus events is discontinued.
This can occur by either presenting the conditioned stimulus alone or by presenting the conditioned stimulus and the unconditioned stimulus independently of one another.
The decline is gradual and relative to this magnitude of the conditioned response.
What is spontaneous recovery?
The reappearance of a conditioned response, following either operant or classical conditioning AFTER it has been experimentally extinguished.
What does Seligman state?
There is an evolutionary response that allows us to adapt and survive.
Psychologists believe that animals and human alike are biologically predisposed to form associations between stimulus that threaten our survival or expose harm to us.
Are all associations in classical conditioning equal?
No, the role of biological preparedness in the development of taste aversions and phobias.
What is systematic desensitisation?
A form of behaviour therapy in which counterconditioning is used to reduced anxiety associated with a particular stimulus.
What are the stages of systematic desensitisation?
- The client is trained in deep-muscle relaxation.
- Various anxiety-provoking situations related to the particular problem are listed in order from weakest to strongest, this is a hierarchy.
- Each of these situations is presented in imagination or in reality, beginning with the weakest whilst the client practices muscle relaxation.
Muscle relaxation is incompatible with the anxiety, the client gradually response less to the anxiety-provoking situations.
This is a conscious choice, if the person is not calm for a step, thy will not progress.
What is operant conditioning?
The learning process in which the strength of the behaviour is modified by the consequences following the behaviour.
The approach is only concerned with observable stimulus-response behaviours.
All behaviours are learned through interaction with the environment.
If a behaviour is followed by a pleasant consequence is it less or more likely repeated?
more likely
If a behaviour is followed by an unpleasant consequence is it less or more likely repeated?
less likely
What are the two key elements to operant conditioning?
Reinforcers and punishers.
What is a reinforcer in operant conditioning?
Any stimulus (action or event) that strengthens or increases the likelihood of a response (behaviour) occurring again.
What is a punisher in operant conditioning?
Any stimulus (action or event) that weakens or decreases the likelihood of a response (behaviour) occurring again.
What is positive reinforcement in operant conditioning?
The procedure of presenting a positive reinforcer after a response.
What is negative reinforcement?
The removal of an aversive stimulus as a consequence of a response, which will increase the probability of that response.
What is a punishment in operant conditioning?
It is defined as the opposite of reinforcement - is designed to weaken, stop or eliminate a response rather than increase it.
What is an aversive punishment in operant conditioning?
Occurs when aversive or unpleasant stimuli is given or applied after an undesired behaviour takes place/occurs, with the aim of making the behaviour less likely to occur in the future.
What is response cost within operate conditioning?
Occurred when certain responses results in the loss (or cost) of something pleasurable. This is when a pleasant stimulus is removed.
What is an example of an aversive punishment in operant conditioning?
Spraying a dog with water or hitting them.
What is an example of an response cost in operant conditioning?
If a kid is naughty their favourite toy is taken away.
What are the advantages of reinforcement?
- Teaches correct behaviour.
- Makes a child, animal or adult feel loved or appreciated.
- Helps develop self-esteem.
- Increases motivation to do the correct behaviour again in the future.
What are the limitations of using punishment?
- Feelings of resentment, frustration, aggression, helplessness may develop in a person who is punished frequently.
- Punished behaviour is not forgotten, its supressed and may return when the punishment, or threat of punishment is no longer present.
- Can create fear of people in authority, which can be generalized to other situations.
What is contiguity in operant conditioning?
Refers to the timing during the learning phase, or how ideas, memories and experiences are linked closely together in time.
Skinner found that it needed to be within 0.5 seconds.
What is contingency in operant conditioning?
The relationship between a response and a reinforcer, or a response and the punisher (dependent on each other).
What are the two kinds of reinforcement?
Continuous and partial reinforcement.
