| Definition | Term |
| events that are inherently reinforcing because the satisfy biological needs | |
| occurs when an organism continues to make a response after delivery of the reinforcer for it has been terminated | |
| the reinforcer is given after a fixed number of nonreinforced responses | |
| events that acquire reinforcing qualities by being associated with primary reinforcers | |
| a form of learning in which voluntary responses come to be controlled by their consequences | |
| any relatively durable change in behavior or knowledge that is due to experience | |
| the reappearance of an extinguished response after a period of nonexposure to the conditioned stimulus | |
| occurs when an event following a response weakens the tendency to make that response | |
| occurs when an organism acquires a response that prevents some aversive stimulation from occurring | |
| a previously neutral stimulus that has, through conditioning, acquired the capacity to evoke a conditioned response | |
| occurs when a response is strengthened because it is followed by the removal of an aversive (unpleasant) stimulus | |
| the reinforcer is given for the first response after a variable time interval has elapsed; the interval length varies around a predetermined avrage | |
| the reinforcer is given for the first response that occurs after a fixed time interval has elapsed | |
| a type of learning in which a stimulus acquires the capacity to evoke a response that was originially evoked by another stimulus | |
| refers to the initial stage of learning something | |
| cues that influence operant behavior by indicating the probable consequences (reinforcement or nonreinforcement) of a response | |
| occurs when an organism that has learned a response to a specific stimulus responds in the same way to new stimuli that are similar to the original stimulus | |
| occurs when an organism that has learned a response to a specific stimulus does not respond in the same way to new stimuli that are similar to the original stimulus | |
