Token reinforcement, choice, and self-control in pigeons

Article Abstract:

Four experiments show that self control in pigeons depends more on the delay to the period of exchange between light-emitting diodes and food than on delay to token presentation. Self control under different token reinforcer situations may differ with the discriminative properties of tokens. Use of token versus food reinforcers with humans versus pigeons, respectively, may be responsible for the differences in their self control choices.

IRT-stimulus contingencies in chained schedules: implications for the concept of conditioned reinforcement

Article Abstract:

Effects of contingencies between interresponse times and the transition between components of chained schedules were investigated with pigeons. Results showed that reinforcing effect of stimulus change varied in strength as an inverse function to delay of the unconditioned reinforcer at the end of the chain.

Discriminated timeout avoidance in pigeons: the roles of added stimuli

Article Abstract:

Two methods of postponement of responses by pigeons are shown and the ratio of response time out (R-TO) and time out (TO) is manipulated across phases and in presence of time-correlated stimuli. The results show that added stimuli serve discriminative functions.
