Term
Learning
Definition
relatively permanent change in behavior due to experience

Definition
learning that associates stimuli to another stimulus
Term
unconditioned response
Definition
an automatic response to a stimulus
Term
unconditioned stimulus
Definition
a stimulus that causes a response without learning or conditioning
Term
conditioned response
Definition
learned response to a stimulus that was once neutral
Term
conditioned stimulus
Definition
an originally neutral stimulus that now has a learned response or condition response
Term
acquisition
Definition
classical condition when the subject just starts to associate UR with a CS to make a CR in operant condition when a reinforced response is strengthened
Term
higher-order conditioning (second-order conditioning)
Definition
where a CS is pair with a new NS which then creates a weaker second CS
Term
extinction
Definition
when the subject no longer pairs a CS with a CR and the CS is again neutral, in operant when a response is no longer enforced
Term
spontaneous recovery
Definition
reappearance of a CS after extinction
Term
generalization
Definition
tendency for similar NS to be mistaken for CS and trigger a CR
Term
discrimination
Definition
distinguishing similar NS from a CS
Term
respondent behavior
Definition
behavior that occurs as an automatic response to a stimulus
Term
operant conditioning
Definition
learning where behavior is strengthened with a reinforcer and diminished with a punisher
Term
operant behavior
Definition
behavior that operates on the enviroment
Term
law of effect
Definition
Thorndike's principle that behaviors followed by positives outcomes more likely than negative
Term
operant chamber
Definition
operant conditioning a chamber with a bar or key the animal can interact with in order to receive food or water
Term
shaping
Definition
in operant conditioning procedure where behavior leading to a larger behavior is reinforced
Term
reinforcer
Definition
any even that strengthens behavior
Term
negative reinforcement
Definition
strengthening behavior by getting rid of negative stimuli
Term
positive reinforcement
Definition
a stimuli that strengthens behavior
Term
primary reinforcer
Definition
a reinforcer that rewards based on common need.. like biological
Term
conditioned reinforcer (secondary reinforcer)
Definition
a stimulus that has reinforcing power through association with a primary enforcer
Term
continuous reinforcement
Definition
giving reinforcement every time desired response happens
Term
partial (intermittent) reinforcement
Definition
reinforcement only part of the time , slower acquisition but greater resistance to extinction
Term
fixed-ratio
Definition
after a certain number of desired behaviors a reinforcement is given
Term
variable-ratio schedule
Definition
reinforcement after a random number of times desired behavior happens
Term
fixed-interval
Definition
reinforcement after a certain amount of time
Term
variable interval
Definition
reinforcement at random times
Term
punishment
Definition
event that diminishes behavior
Term
cognitive map
Definition
mental representation of the layout of enviroment
Term
latent learning
Definition
learning that occurs but is not apparent until incentive to demonstrate
Term
intrinsic motivation
Definition
desire to perform behavior because good internal feelings

extrinsic motivation
Definition
