  1. bias from matching
    A deviation from matching in which one alternative attracts a higher proportion of responses than would be predicted by matching, regardless of whether that alternative contains the richer verssus poorer schedule.
  2. 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.
  3. concurrent schedule of reinforcement
    A complex schedule consisting of the simultaenous presentation of two or more independent schedules, each leading to a reinforcer.
  4. impulsiveness
    With respect to choice between two rewards, selecting a smaller sooner reward over a larger later reward.
  5. matching law
    The principle that the proportion of responses emitted on a particular schedule matches the proportion of reinforcers obtained on that schedule.
  6. 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-terme ffect on overall amount of reinforcement.
  7. 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.
  8. self-control
    With respect to choice between two rewards, selecting a larger later reward over a smaller sooner reward.
  9. small-but-cumulative effects model
    Each individual choice on a self-control task has only a small but cumulative effect on our likelihood of obtaining the desired long-term outcome.
  10. 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.
