-
a relatively permanent change in behavior brought about by experience
learning
-
a type oof learning in which a neutral stimulus comes to bring about a response after it is paired with a stimulus that naturally brings about that response
classical conditioning
-
a stimulus that, before conditioning, does not naturally bring about the response of interest
neutral stimulus
-
a stimulus taht naturally brings about a particular response without having been learned
unconditioned stimulus
-
a response that is natural and needs no training (salivation at the smell of food)
unconditioned response
-
a once neutral stimulus taht has been paired with an unconditioned stimulus to bring about a response formerly caused only by the unconditioned stimulus
conditioned stimulus
-
a response that, after conditioning, follows a previously neutral stimulus (salivation at the ringing of a bell)
conditioned response
-
a basic phenomenon of learning that occurs when a previously conditioned response decreases in frequency and eventually disappears
extinction
-
the reemergence of an extinguished conditioned response after a period of rest and with no further conditioning
spontaneous recovery
-
a process in which, after a stimulus has been conditioned to prodice a particular response, stimuli that are similar to the original stimulus produce the same response
stimlus generalization
-
the process that occurs if two stimuli are sufficiently distinct from one another that one evokes a conditioned response but the other does not; the ability to differentiate between stimuli
stimulus discrimination
-
learning in which a voluntary response is strengthened or weakened, depending on its favorable or unfavorable consequences
operant conditioning
-
the process by which a stimulus increases the probability that a preceding behavior will be repeated
reinforcement
-
any stimulus that increases the probability that a preceding behavior will occur again
reinforcer
-
a stimulus that decreases the probability that a previous behavior will occur again
punishment
-
a stimulus added to the environment that brings about an increase in a proceding response
positive reinforcer
-
an unpleasant stimulus whose removal leads to an increase in the probability that a preceding response will be repeated in the future
negative reinforcer
-
different patterns of frequency and timing of reinforcement following desired behavior
schedules of reinforcement
-
reinforcing of a bahavior every time it occurs
continuous reinforcement schedule
-
reinforcing of a behavior some but not all of the time
partial / intermittent reinforcement schedule
-
a schedule by which reinforcement is given only after a specific number of responses are made
fixed-ratio schedule
-
a schedule by which reinforcement occurs after a varying number of responses rather than after a fixed number
variable- ratio schedule
-
a schedule that provides reinforcement for a response only if a fixed time period had elapsed, making overall rates of response relatively low
fixed-interval schedule
-
a schedule by which the time between reinforcement varies around some average rather than being fixed
variable-interval schedule
-
the process of teaching a complex behavior by rewarding closer and closer approximations of the desired behavior
shaping
-
s formalized technique for promoting the frequency of desirable behaviors and decreasing the incidence of unwanted ones
behavior modification
-
an approach to the study of learning that focuses on the thought processes that underlie learning
cognitive learning theory
-
learning in which a new behavior is acquired but is not demonstrated until some incentive is provided for displaying it
latent learning
-
learning by observing the behavior of another person, or model
observational learning
