Chapter 12 Flashcards
Avoidance Contingency
A contingency in which a response prevents or postpones the presentation of a stimulus.
Conditioned Negative Reinforcer
A previously neutral stimulus change that functions as a negative reinforcer because of prior pairing with one or more negative reinforcers.
Discriminated Avoidance
A contingency in which responding in the presence of a signal prevents the onset of a stimulus from which escape is a reinforcer.
Escape Contingency
A contingency in which a response terminates (produces escape from) an ongoing stimulus.
Free-Operant Avoidance
Any operant behavior that results in minimal displacement of the participant in time and space. A free operant can be emitted at nearly any time; it is discrete, it requires minimal time for completion, and it can produce a wide range of response rates.
Negative Reinforcement
A stimulus whose termination (or reduction in intensity) functions as reinforcement.
Unconditioned Negative Reinforcer
A stimulus that functions as a negative reinforcer as a result of the evolutionary development of the species (phylogeny); no prior learning is involved (e.g., shock, loud noise, intense light, extreme temperatures, strong pressure against the body).
