PSYCH CHAP 7 Flashcards
(34 cards)
behavioral contrast
A response pattern in which an organism evaluates a reward relative to other available rewards or those that have been available recently.
blocking effect
A result showing that an animal learns nothing about a stimulus if the stimulus provides no new information.
classical conditioning
A form of learning in which one stimulus is paired with another so that the organism learns a relationship between the stimuli.
compensatory response
A response that offsets the effects of the upcoming unconditioned stimulus.
conditioned response (CR)
A response elicited by an initially neutral stimulus?the conditioned stimulus (CS)?after it has been paired repeatedly with an unconditioned stimulus (US). See also conditioned stimulus (CS), unconditioned response (UR), unconditioned stimulus (US).
conditioned stimulus (CS)
An initially neutral stimulus that comes to elicit a new response due to pairings with the unconditioned stimulus. See also conditioned response (CR), unconditioned response (UR), unconditioned stimulus (US).
discrimination
An aspect of learning in which the organism learns to respond differently to stimuli that have been associated with a US (or reinforcement), and stimuli that have not.
dishabituation
An increase in responsiveness when something novel is presented, following a series of presentations of something familiar.
extinction
The weakening of a learned response that is produced if a conditioned stimulus is now repeatedly presented without the unconditioned stimulus, or if a previously reinforced operant behavior is no longer reinforced.
habituation
A decline in the response to a stimulus once the stimulus has become familiar.
inhibitor
A stimulus signaling that an event is not coming, which elicits a response opposite to the one that the event usually elicits.
instrumental conditioning
A form of learning in which the participant receives a reinforcer only after performing the desired response, and thereby learns a relationship between the response and the reinforcer. Also called operant conditioning.
interval schedule
A pattern of delivering reinforcements only after a certain amount of time has passed.
latent learning
Learning that occurs without a corresponding change in behavior.
law of effect
Thorndike’s theory that a response followed by a reward will be strengthened, whereas a response followed by no reward (or by punishment) will be weakened.
learned helplessness
A condition of passivity apparently created by exposure to inescapable aversive events. This condition inhibits or prevents learning in later situations in which escape or avoidance is possible.
long-term potentiation (LTP)
A long-lasting increase in a neuron’s response to specific inputs, caused by repeated stimulation. See also activity dependence.
mirror neurons
Neurons that fire whenever an animal performs an action, such as stretching out its arm or reaching toward a target, and also whenever the animal watches another performing the same action.
observational learning
The process of watching how others behave and learning from their example.
operant
In Skinner’s system, an instrumental response that is defined by its effect (the way it operates) on the environment. See instrumental conditioning.
partial reinforcement
A learning condition in which only some of the organism’s responses are reinforced.
prepared learning
Learning that occurs without extensive training because of an evolved predisposition to the behavior.
presynaptic facilitation
A process, documented in studies of Aplysia, that underlies many kinds of learning. It occurs when learning results in an increased release of neurotransmitter into the synapse.
ratio schedule
A pattern of delivering reinforcements only after a certain number of responses.
