Humans' choice in a self-control choice situation: sensitivity to reinforcer amount, reinforcer delay, and overall reinforcement density

Article Abstract:

An experiment was conducted to test whether local reinforcement density (LRD) or overall reinforcement density (ORD) could better predict human self-control situations. The analysis of results show that human self-control choices are more consistent with ORD rather that LRD predictions. It was also found that the amount of reinforcement rather than reinforcement delay exerts more influence in human self-control choices.

Relative sensitivity to reinforcer amount and delay in a self-control choice situation

Article Abstract:

Experiments are conducted to determine the sensitivity of rats to reinforcer amount and delay in a self-control choice situation. Using a concurrent-chains schedule in which a single variable-interval schedule arranges entry into one of two terminal-link delay periods or fixed-interval schedules, it is shown that the relative sensitivities to amount and delay differ as a function of delay.

Choice between constant and variable alternatives by rats: effects of different reinforcer amounts and energy budgets

Article Abstract:

The authors discuss experiments on rats which tested the animals' sensitivity to variations in delay to food and amount of food. Constant and variable delay alternatives and food intakes are compared.
