learning | A relatively permanent change in behavior brought about by experience (Module 15)
|
|
|
|
neutral stimulus | A stimulus that, before conditioning, does not naturally bring about the response of interest (Module 15)
|
|
|
|
spontaneous recovery | The re-emergence of an extinguished conditioned response after a period of rest (Module 15)
|
|
|
|
stimulus discrimination | The ability to differentiate between stimuli (Module 15)
|
|
|
|
stimulus generalization | Response to a stimulus that is similar to but different from a conditioned stimulus; the more similar the two stimuli, the more likely generalization is to occur (Module 15)
|
|
|
|
unconditioned response (UCR) | A response that is natural and needs no training (e.g., salivation at the smell of food) (Module 15)
|
|
|
|
unconditioned stimulus (UCS) | A stimulus that brings about a response without having been learned (Module 15)
|
|
|
|
classical conditioning | A type of 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 (Module 15)
|
|
|
|
conditioned response (CR) | A response that, after conditioning, follows a previously neutral stimulus (e.g., salivation at the ringing of a bell) (Module 15)
|
|
|
|
conditioned stimulus (CS) | A once-neutral stimulus that has been paired with an unconditioned stimulus to bringabout a response formerly caused only by the unconditioned stimulus (Module 15)
|
|
|
|
extinction | One of the basic phenomena of learning that occurs when a previously conditioned response decreases in frequency and eventually disappears (Module 15)
|
|
|
|
fixed-interval schedule | A schedule that provides reinforcement for a response only if a fixed time period has elapsed, making overall rates of response relatively low (Module 16)
|
|
|
|
fixed-ratio schedule | A schedule whereby reinforcement is given only after a certain number of responses are made (Module 16)
|
|
|
|
negative reinforcer | An unpleasant stimulus whose removal leads to an increase in the probability that a preceding response will occur again in the future (Module 16)
|
|
|
|
operant conditioning | Learning in which a voluntary response is strengthened or weakened, depending on its favorable or unfavorable consequences (Module 16)
|
|
|
|
partial (or intermittent) reinforcement schedule | Behavior that is reinforced some but not all of the time (Module 16)
|
|
|
|
positive reinforcer | A stimulus added tothe environment that brings about an increase in a preceding response (Module 16)
|
|
|
|
punishment | A stimulus that decreases the probability that a previous behavior will occur again (Module 16)
|
|
|
|
reinforcement | The process by which a stimulus increases the probability that a preceding behavior will be repeated (Module 16)
|
|
|
|
reinforcer | Any stimulus that increases the probability that a preceding behavior will occur again (Module 16)
|
|
|
|
schedules of reinforcement | The frequency and timing of reinforcement following desired behavior (Module 16)
|
|
|
|
shaping | The process of teaching a complex behavior by rewarding closer and closer approximations of the desired behavior (Module 16)
|
|
|
|
variable-interval schedule | A schedule whereby the time between reinforcements varies around some average rather than being fixed (Module 16)
|
|
|
|
variable-ratio schedule | A schedule whereby reinforcement occurs after a varying number of responses rather than after a fixed number (Module 16)
|
|
|
|
behavior modification | A formalized technique for promoting the frequency of desirable behaviors and decreasing the incidence of unwanted ones (Module 16)
|
|
|
|
continuous reinforcement schedule | Behavior that is reinforced every time it occurs (Module 16)
|
|
|
|
latent learning | Learning in which a new behavior is acquired but is not demonstrated until some incentive is provided for displaying it (Module 17)
|
|
|
|
observational learning | Learning through observing the behavior of another person called a mode(Module 17)
|
|
|
|
cognitive-social learning theory | The study of the thought processes that underlie learning (Module 17)
