Melioration theory suggests that performance in choice situations arises from a process in which subjects allocate more time to alternatives that provide the higher local rate of reinforcers. If this process is unconstrained (as in concurrent aperiodic schedules), melioration predicts a strict equality between molar time-allocation (and, as a result, response-allocation) ratios and molar ratios of overall obtained reinforcers on concurrent variable-interval schedules. The available data… CONTINUE READING
