-
learning
a process based on experience that results in a relatively permanent change in behavior or behavioral potential
-
learning-performance distinction
the difference between what has been learned and what is expressed in overt behavior
-
habituation
a decrease in behavioral response when a stimulus is being presented repeatedly
-
sensitization
an increase in behavioral response when a stimulus is presented repeatedly
-
behavior analysis
the area of psychology that focuses on the environmental determinants of learning and behavior
-
classical conditioning
a type of learning in which a behavior (conditioned response) comes to be elicited by a stimulus (conditioned stimulus) that has acquired its power through an association with a biologically significant stimulus (unconditional stimulus)
-
reflex
an unlearned response elicited by specific stimuli that have biological relevance for an organism
-
unconditional stimulus (UCS)
In classical conditioning, the stimulus that elicits an unconditioned response
-
unconditioned response (UCR)
In classical conditioning, , the response elicited by an unconditioned stimulus without prior training or learning
-
conditioned stimulus (CS)
In classical conditioning, a previously neutral stimulus that comes to elicit a conditioned response
-
conditioned response (CR)
In classical conditioning, a response elicited by some previously neutral stimulus that occurs as a result of pairing neutral stimulus with an unconditional stimulus
-
acquisition
the stage in classical conditioning experiment during which the conditioned response is first elicited by the conditioned stimulus
-
extinction
`in conditioning, the weakening of a conditioned association in the absence of a reinforcer or unconditioned stimulus
-
spontaneous recovery`
the reappearance of an extinguished conditioned response after a rest period
-
stimulus generalization
the automatic extension of conditioned responding to similar stimuli that have never been paired with the unconditioned stimulus
-
stimulus discrimination
a conditioning process in which an organism learns to respond differently to stimuli that differ from the conditioned stimulus on some dimension
-
law of effect
a basic law of learning that states that the power of a stimulus to evoke a response is strengthened when the response is followed by a reward and weakened when it is not followed by a reward
-
operant conditioning
learning in which the probability of a response is changed by a change in its consequences`
-
operant
behavior emitted by an organism that can be characterized to terms of the observable effects it has on the environment
-
reinforcement contigency
a consistent relationship between a response and the changes in the environment it produces
-
reinforces
any stimulus that, when made contingent on a response, increases the probability of that response
-
positive reinforcement
a behavior is followed by the presentation of an appetitive stimulus, increasing the probability of behavior
-
negative reinforcement
a behavior is followed by the removal of an aversive stimulus, increasing the probability of that behavior
-
escape conditioning
a form of learning in which animals acquire a response that will allow them to escape from an aversive stimulus
-
avoidance conditioning
`a form of learning in which animals require responses that allow them to avoid aversive stimuli before they begin
-
operant extinction
when a behavior no longer produces predictable consequences, its return to the level of occurrence it had before operant conditioning
-
punisher
any stimulus that, when made contingent on a response, decreases the probability of that response
-
positive punishment
a behavior is followed by the presentation of an aversive stimulus, decreasing the probability of that behavior
-
negative punishment
a behavior is followed by the removal of an appetitive stimulus, decreasing the probability of that behavior
-
discriminative stimulus
stimulus that acts as a predictor of reinforcement, signalling when particular behavior will result in positive reinforcement
-
three-term contigency
the means by which an organism learns that, in the presence of some stimuli but not others, their behavior is likely to have a particular effect on the environment
-
primary reinforcer
biologically determined reinforcer, such as food and water
-
conditioned reinforcer
in classical conditioning, a formerly neutral stimulus that has become a reinforcer
-
schedule of reinforcement
in operant conditioning, a pattern of delivering and withholding reinforcement
-
partial reinforcement effect
the behavioral principle that states the responses acquired under intermittent reinforcement are more difficult to extinguish than those acquired with continuous reinforcement
-
fixed-ratio (FR) schedule
a schedule of reinforcement in which a reinforcer is delivered for the first response made after a fixed number of responses
-
variable-ratio (VR) schedule
A schedule of reinforcement in which a reinforcer is delivered for the first response made after a variable number of response whose average is predetermined
-
fixed interval (FI) schedule
a schedule of reinforcement in which a reinforcer is delivered for the first response made after a fixed period of time
-
variable-interval (VI) schedule
a schedule of reinforcement in which the reinforcer is delivered for the first response made after a variable period of time whose average is predetermined
-
shaping by successive approximations
a behavioral method that reinforces responses that successfully approximate and ultimately matched the desired response
-
biological constraint on learning
any limitation on an organisms capacity to learn that is caused by the inherited sensory, response, or cognitive capabilities of members of a given species
-
instinctual drift
the tendency for learned behavior to drift toward instinctual behavior over time
-
taste-aversion learning
a biological constraint on learning in which an organism learns in one trial to avoid food whose ingestion is followed by illness
-
comparative cognition
the study of development of cognitive abilities across species and the continuity of abilities from nonhuman to human animals
-
cognitive map
a mental representation of physical space
-
observational learning
the process of learning new responses by watching the behavior of another
