Learning
| Question | Answer |
|---|---|
| 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. |
| Neutral Stimulus | A stimulus that, before conditioning, does not naturally bring about the response without having been learned. |
| Unconditioned Stimulus (UCS) | A stimulus that naturally brings about a particular response without having been learned. |
| Unconditioned Response (UCR) | A response that is natural and needs no training. |
| Conditioned Stimulus (CS) | A once neutral stimulus that has been paired with an unconditioned stimulus to bring about a response formerly caused only by the unconditioned stimulus. |
| Conditioned Response (CR) | A response that, after conditioning, follows a previously neutral stimulus. |
| Extinction | A basic phenomenon of learning that occurs when a previously conditioned response decreases in frequency and eventually disappears. |
| Spontaneous Recovery | The reemergence of an extinguished conditioned response after a period of rest and with no further conditioning. |
| Stimulus Generalization | A process on which, after a stimulus has been conditioned to produce a particular response, stimuli that are similar to the original stimulus produce the same response. |
| Stimulus Discrimination | 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. |
| Operant Conditioning | Learning in which a voluntary response is strengthened or weakened, depending on its favorable or unfavorable consequences. |
| Reinforcement | The process by which a stimulus increases the probability that a preceding behavior will be repeated. |
| Reinforcer | Any stimulus that increases the probability that a preceding behavior will occur again. |
| Positive Reinforcer | A stimulus added to the environment that brings about an increase in a preceding response. |
| Negative Reinforcer | An unpleasant stimulus whose removal leads to an increase in the probability that a preceding response will be repeated in the future. |
| Punishment | A stimulus that decreases the probability that a previous behavior will occur again. |
| Schedules of Reinforcement | Different patterns of frequency and timing of reinforcement following desired behavior. |
| Continuous Reinforcement Schedule | Reinforcing of a behavior every time it occurs. |
| Partial (or intermittent) Reinforcement Schedule | Reinforcing of a behavior some but not all of the time. |
| Fixed-Ratio Schedule | A schedule by which reinforcement is given only after a specific number of responses are made. |
| Variable-Ratio Schedule | A schedule by which reinforcement occurs after a varying number of responses rather than after a fixed number. |
| 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. |
| Variable-Interval Schedule | A schedule by which the time between reinforcements varies around average rather than being fixed. |
| Shaping | The process of teaching a complex behavior by rewarding closer and closer approximations of the desired behavior. |
| Behavior Modification | A formalized technique for promoting the frequency of desirable behaviors and decreasing the incidence of unwanted ones. |
| Cognitive Learning Theory | An approach to the study of learning that focuses of the thought processes that underlie learning. |
| Latent Learning | Learning in which a new behavior is acquired but it is not demonstrated until some incentive is provided for displaying it. |
| Observational Learning | Learning by observing the behavior of another person, or model. |
