BEHAVIORAL LEARNING
TWO SCHOOLS OF THOUGHT
Cognitive
- "learning is knowledge"
- focuses on internal characteristics
- emphasizes the role of memory and thinking
Behavioral
- "learning as behavior"
- focuses on changes in behavior that occur as a result of experience
- emphasizes stimuli and response behaviors
SUMMARY OF LEARNING THEORIES
Reasoning
individuals use thinking to restructure and recombine existing
information and new information to form new associations and concepts
Iconic rote learning
two or more concepts become associated without conditioning
and without reasoning
Vicarious learning (modeling)
behaviors are learned by watching the outcomes of others'
behaviors or by imagining the outcome of potential behavior
Operant (instrumental) conditioning
a response that is given reinforcement is more likely to be
repeated when the same situation arises in the future
Classical conditioning
a response elicited by one object will be elicited by the second
object if both objects frequently occur together
BEHAVIORAL LEARNING
a process in which experience with the environment leads to a
relatively permanent change in behavior or the potential for a
change in behavior
Three major approaches:
- classical conditioning
- operant conditioning
- vicarious learning
CLASSICAL CONDITIONING
- stimulus =======> response
- behavior is 'elicited'
OPERANT CONDITIONING
- behavior =======> reward (or punishment) [or positive/negative
reinforcement]
- behavioral response is 'emitted'
- behavior is caused by altering the consequences that follow
the behavior
CLASSICAL CONDITIONING
unconditioned stimulus (UCS)
any stimulus capable of eliciting autonomically an unconditioned
response (note that it can be possible for an unconditioned or
'unconditional' stimulus to have previously been conditioned)
unconditioned response (UCR)
the reflexive, involuntary response elicited by an unconditioned
stimulus
conditioned stimulus (CS)
a previously neutral stimulus that, when paired with an unconditioned
stimulus, may elicit a conditioned response
conditioned response (CR)
the response elicited by the conditioned stimulus when classical
conditioning occurs
OPERANT CONDITIONING
operant
naturally occurring actions of an organism in the environment
reinforcements
stimuli that occur after the behavior, affecting the likelihood
that the behavior will be emitted again by an organism
extinction
the disappearance of a response due to lack of reinforcement
shaping
a process through which a new operant behavior is created by
reinforcing successive approximations of the desired behavior
