Test 3: Chapters 6 + 7 Flashcards
What is learning?
A relatively permanent change in behaviour, knowledge, capability, or attitude that is acquired through experience and cannot be attributed to illness, injury, or maturation.
What are the 3 forms of learning?
- Classical conditioning
- Operant conditioning
- Social cognitive theory
What is classical conditioning?
A form of learning in which an association is formed between one stimulus and another.
What is pairing?
Putting two things together so that an association can be formed (bell+food=salivating)
What is an unconditioned stimulus (US)?
Automatically produces a response.
- Food
- Loud noise
What is an unconditioned response (UR)?
Is made to the US.
- Salivating
- Fear
What is a neutral stimulus (NS)?
Does not produce a response.
- Bell/researcher
- Balloon
What is a conditioned stimulus (CS)?
Was previously NS but now is conditioned to produce a response.
- Bell/researcher
- Balloon
What is a conditioned response (CR)?
Is the response made to the CS.
- Salivating
- Fear
What is extinction (CC)?
The CS is repeatedly presented without the US (CS becomes NS again).
What is spontaneous recovery (CC)?
Sometimes occurs when, after extinction, the CS is again presented with the US causing the CR to reappear.
(Can take 20 times originally, pause for while - extinction - but then next time they’re paired it only takes once to get the reaction)
What is generalization (CC)?
A stimulus, similar to the CS, elicits the CR.
(Dogs can generalize all bells with similar sounds, Albert is afraid of all things with white fur, fear of doctor generalized to fear of hospital)
What is discrimination (CC)?
CR is made only to the CS and not to any other similar stimuli.
(Afraid of apples but not of apple sliced, only salivate when hearing the right bell tone)
What are the factors affecting classical conditioning?
- Number of pairings of CS and US
- Intensity of US
- How reliable CS predicts US (false fire alarm)
- Time between the CS and US
- Survival of species
What are examples of classical conditioning in our life?
- Songs, scents (pleasant/not)
- Taste aversion
- Fears and phobias
- Drug use, tolerance and environment
- Advertising and commercials
- Fetish and sexual arousal
- The dog whisperer
- Removal of fears
What is operant conditioning?
A form of learning in which the consequences of behaviour are manipulated in order to increase or decrease the frequency of a response or to shape an entirely new response.
(Shaping behaviour with consequences)
What is shaping?
Reinforcing or rewarding successive approximations of the desired response.
Encouragement for attempting the behaviour.
(Give rat a treat so he keeps trying to push on the lever, say god job to axel when he tries to answer a question so he keeps trying)
What are the types of consequences?
- Reinforcement: a happy consequence :)
- Punishment: a sad consequence :(
What is a reinforcer?
Anything that follows a behaviour that increases the likelihood that the behaviour will occur again.
What is extinction (OC)?
Occurs when reinforcement is withheld.
What is generalization (OC)?
Occurs when we do respond to similar stimuli/situations as the conditioned ones.
What is discrimination (OC)?
Occurs when we do not respond to similar stimuli/situations as the conditioned ones (because they are not rewarded).
What are the types of reinforcement?
- Positive
- Negative
What is positive reinforcement?
A behaviour that is likely to occur again because it was followed by a pleasant or desirable consequence.
- Giving something happy/good
What is negative reinforcement?
A behaviour is likely to occur again because it was followed by the termination of an aversive condition.
- Taking away something sad/bad
What are the types of reinforcers?
- Primary
- Secondary
What is a primary reinforcer?
Fulfill a basic physical need for survival and do not depend on learning (food, water, sleep, no pain, sex).
What is a secondary reinforcer?
Are acquired or learned by association with other reinforcers (money, praise, awards, bonuses, grades, smiles).
What are the schedules of reinforcement?
- Continuous
- Partial
- Ratio?
- Interval?
What is a continuous schedule of reinforcement?
Occurs when each correct response is reinforced.
What is a partial reinforcement schedule?
Occurs when correct responses are reinforced randomly or intermittently.
(Trip to dollar store after week of continuous good homework)
What is a ratio schedule?
Number of times you have to behave.
What is a fixed ratio schedule?
Reinforcement given after a fixed number of correct responses.
Pause after reinforcement then high response rate.
What is a variable ratio schedule?
Reinforcement given after a varying number of correct responses.
Highest response rate with no pause.
Most resistant to extinction.
