learning
a relatively permanent change in an organisms behavior due to experience
habituation
decreasing responsiveness with repeated stimulation
associative learning
learning that certain events go together
classical conditioning
a type of learning in which one learns to link two or more stimuli and anticipate events
behaviorism
the view that psychology 1) should be an objective science that 2) studies behavior without reference to mental processes.
unconditioned response
the unlearned, naturally occurring response to the unconditioned stimulus
unconditioned stimulus
a stimulus that unconditionally--naturally and automatically--triggers a response.
conditioned response
the learned response to a previously neutral (but now conditioned) stimulus
conditioned stimulus
an originally irrelevant stimulus, that, after association with an unconditioned stimulus, comes to trigger a conditioned response.
acquisition
the initial stage when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response.
higher-order conditioning
a procedure in which the conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second (often weaker) conditioned stimulus
extinction
the diminishing of a conditioned response
spontaneous recovery
the reappearance, after a pause, of an extinguished conditioned response
generalization
the tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similar responses.
discrimination
the learned ability to distinguish between a conditioned stimulus and stimuli that do not signal a conditioned response
learned helplessness
the hopelessness and passive resignation an animal or human learns when unable to avoid repeated aversive events
operant conditioning
a type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher
law of effect
Thorndike's principle that behaviors followed by favorable consequences become more likely, and that behaviors followed by unfavorable consequences become more unlikely
shaping
an operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior.
discriminative stimulus
a stimulus that elicits a response after association with reinforcement
reinforcer
any event that strengthens the behavior if it follows
positive reinforcement
increasing behaviors by presenting positive stimuli
negative reinforcement
increasing behaviors by stopping or reducing negative stimuli
continuous reinforcement
reinforcing the desired response every time it occurs
partial reinforcement
reinforcing a response only part of a time
fixed-ratio schedule
a reinforcement schedule that reinforces a response only after a specified number of responses
variable ratio schedule
reinforcement schedule that reinforces a response after an unpredictable number of responses
fixed-interval schedule
a reinforcement schedule that reinforces a response only after a specified time has elapsed
variable-interval schedule
reinforcement schedule that reinforces a response after an unpredictable amount of time has elapsed
punishment
an event that decreases the behavior that it follows
latent learning
learning that occurs but is not apparent until there is an incentive to demonstrate it.
insight learning
a sudden and often novel realization of the solution to a problem
intrinsic motivation
a desire to perform a behavior effectively for its own sake
extrinsic motivation
a desire to perform a behavior to receive promised rewards or avoid threatened punishment
observational learning
learning by observing others
modeling
the process of observing and imitating a specific behavior.
