Discounting of Probabilistic Reinforcers by Pigeons
… an innovative procedure, one that combined the concurrent-chains and the adjusting-amount procedures, to study probability discounting in pigeons. The concurrent-chains procedure included a non-independent VI 30-second schedule in the initial link, during which pigeons revealed their preference …

Effects of reinforcement delays on procrastination in pigeons
… work requirement in the terminal links of a concurrent-chains schedule. The early-onset work requirement was preferred. This preference held in Phase 2, when a delay to reinforcement was added, following completion of the early-onset work requirement. These results suggest that when work …

Quantity versus quality : the opportunity to choose back-up reinforcers in a token economy
… varied token reinforcers was presented in a concurrent -chains arrangement. The dependent variables were the number of letters traced per min and the number of tokens earned per min during 3-min sessions, and the percentage of selections for single versus varied conditions. Results showed …

Shaping Brain and Behaviour: Investigating the Properties and Electrophysiological Correlates of Reinforcement
… by examining conditional reinforcement in a concurrent-chains procedure. Both the choice and the ERP results verified these joint predictions, demonstrating the superiority of the signalling account. Taken together, these results show that the signalling theory is a more accurate and useful …

Conditional Reinforcement: A Comprehensive Review and Investigation of Terminal Link Stimulus Functions
Three experiments arranged a concurrent chained schedule that probabilistically arranged reinforcement or extinction. In Experiments 1 and 2, the probability of obtaining food in the terminal link period, following a given left or right lever choice, was the complement of the probability that the …
