| Term | Definition |
|---|---|
| concurrent schedule of reinforcement | A complex schedule consisting of the simultaneous presentation of two or more independent schedules, each leading to a reinforcer. |
| matching law | The principle that the proportion of responses emitted on a particular schedule matches the proportion of reinforcers obtained on that schedule. |
| undermatching | A deviation from matching in which the proportion of responses on the richer schedule versus poorer schedule is less different than would be predicted by matching. |
| impulsiveness | With respect to choice between two rewards, selecting a smaller sooner reward over a larger later reward. |
| bias from matching | A deviation from matching in which one response alternative attracts a higher proportion of responses than would be predicted by matching, regardless of whether that alternative contains the richer versus poorer schedule. |
| overmatching | A deviation from matching in which the proportion of responses on the richer schedule versus poorer schedule is more different than would be predicted by matching. |
| melioration theory | A theory of matching that holds that the distribution of behavior in a choice situation shifts toward those alternatives that have higher value regardless of the long-term effect on overall amount of reinforcement. |
| self-control | With respect to choice between two rewards, selecting a larger later reward over a smaller sooner reward. |
| commitment response | An action carried out at an early point in time that serves to either eliminate or reduce the value of an upcoming temptation. Also called a precommitment response. |
| small-but-cumulative effects model | A model of self-control in which each individual choice between a smaller sooner and larger later reward has only a small but cumulative effect on our likelihood of obtaining the desired outcome. |
| overmatching (picture) | more sensitivity to the relative rate of reinforcement than predicted by the comparable rate |
| undermatching (picture) | less sensitivity to the relative rate of reinforcement than predicted by the comparable rate |
| bias from matching (picture) | deviation where one response alternative attracts a higher proportion of responses than would be predicted |
