Chapter 15 - Skinner Flashcards
What is the law of effect?
Learning takes place mostly because of the effects that follow a response
- satisfiers “stamp in” behaviour
- annoyers inhibit behaviour
What two theorists were most influential to Skinner’s theory, and how?
Thorndike - law of effect
Watson - goal of psychology is prediction and control of behaviour, which can be studied objectively
Scientific Behaviourism
- human behaviour should
be studied scientifically - hypothetical internal mental functions are unnecessary and unobservable
- internal states exist but are outside domain of science
- aim is to predict and control behaviour, not explain its causation
What is cosmology?
The realm of philosophy concerned with the nature of causation (which Skinner had no interest in)
What is classical conditioning?
Pairing a neutral (conditioned) stimulus with an unconditioned stimulus (usually biologically potent) repeatedly until the conditioned stimulus elicits a conditioned response resembling the original unconditioned response even in the absence of the unconditioned stimulus
What is operant conditioning?
Reacting to behaviour with reinforcement or punishment
What is shaping?
Gradually molding a complex set of behaviours through progressive reinforcement of successive approximations
What is operant discrimination?
Organisms learn to respond to some elements in the environment and not others as a consequence of their reinforcement history
What are the types of reinforcement?
Positive - presenting desirable stimulus
Negative - removing aversive stimulus
What are the types of punishment?
- removing desirable stimulus
- presenting aversive stimulus
What is a conditioned reinforcer?
Something which is indirectly reinforcing due to its association with primary reinforcers
- also called secondary reinforcers
What is a generalized reinforcer?
A reinforcer associated with more than one primary reinforcer
What are the schedules of reinforcement?
- fixed-ratio
- fixed-interval
- variable-ratio
- variable-interval
What is the difference between extinction & operant extinction?
Extinction = tendency of previously acquired response to progressively weaken upon non-reinforcement
Operant extinction = experimenter systematically withholding reinforcement to extinguish a behaviour
What three forces shape behaviour and personality, according to Skinner?
- natural selection
- cultural evolution
- individual history of reinforcement
