 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 response in which a response terminates (escapes from) an ongoing stimulus |
| Free-operant avoidance | A contingency in which responses at any time during an interval prior to the scheduled onset of an aversive stimulus delays the presentation of the aversive stimulus. |
| Negative reinforcement | The termination, reductions, or postponement of a stimulus contingent on the occurrence of a response, which leads to an increase in the in the future occurrence of that response. |
| 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). |
