The effects of preexperimental diet upon reward magnitude effects

Reward magnitude effects as a function of within-day trial-by-trial analysis

“…For example, such factors as satiation (Campbell et aI., 1972), single-vs. multiplepellet rewards (Daly, 1972;McCain, 1969), rate of approach to asymptote (McHose & Moore, 1976), preexperimental diet (prytula, Davis, & Voorhees, 1978), and the particular segment of the instrumental response chain that is measured or reported (Davis et aI., 1976) have been shown to be related to the development and/or collapse of reward magnitude effects. In reviewing these apparently divergent results, as well as 11 large-vs. small-reward comparisons from their own laboratory, McHose and Moore (1976) note one consistent point of agreement: The rate of approach to asymptote appears to be positively related to reward magnitude.…”
