Commitment using punishment

Article Abstract:

Hyperbolic time discounting states the choice of a smaller-sooner and a larger-later reward may reverse over time. An experiment was designed to investigate this, with pigeons exposed to a two-link choice procedure after establishing an order of preference of a smaller-sooner reinforcer, a larger-later reinforcer, and a punishment following the smaller-sooner reinforcer. Results showed that the preference for the punished smaller-sooner alternative increased as the delay between the initial and terminal links increased.

Preference reversals with food and water reinforcers in rats

Article Abstract:

Rats given the choice between smaller, sooner reward and the larger, later alternative tended to select the latter as reward delivery increased from 0 to 25 seconds. This supports the view that self-control is better understood as choice behavior and that species differences in this area may reflect differences in degree rather than in kind.

Economic and biological influences on key pecking and treadle pressing in pigeons

Article Abstract:

Research indicates that biological considerations can be integrated into animal learning research without proposing limitations that constrict general laws of learning. Data were obtained from conditional key pecking and treadle pressing experiments with pigeons.
