Determinants of choice for pigeons and humans on concurrent-chains schedules of reinforcement. Journal of the Experimental Analysis of Behavior, 52, 97-109.https://hdl.handle.net/20.500.14078/1855Demonstrated that the determinants of choice and preference are different for pigeons and humans exposed to the same concurrent schedules of reinforcement. Four male pigeons and 4 male undergraduates replicated E. Fantino's (see record 1970-03386-001 ) experiment that manipulated initial-link duration to test the divergent predictions of the delay-reproduction and reinforcement-density equations. Condition 1 exposed Ss to VI 90-sec and 30-sec initial links. Conditions 2 and 3 arranged equal initial-link schedules of 40 sec or 120 sec. Pigeons strongly preferred the alternative with the shorter terminal-link time to reinforcement, while delay-reduction equations did not predict the performance of humans in the unequal initial-link.enAll Rights Reservedchoice behaviorconcurrent reinforcement schedulespreferencestask complexitypigeonsspecies differencesanimalschoice behaviorColumbidaehumansmalemodels, psychologicalreinforcement (psychology)reinforcement scheduletime factorsArticlehttps://doi.org/10.1901/jeab.1989.52-97
