DOI: 10.1002/jeab.239
Abstract: In a frequently used suboptimal-choice procedure pigeons choose between an alternative that delivers three food pellets with p = 1.0 and an alternative that delivers ten pellets with p = 0.2. Because pigeons reliably choose… read more here.

DOI: 10.1002/jeab.553
Abstract: Pigeons (n = 14) were trained in a concurrent-chains suboptimal choice procedure that tested the effect of an increased ratio requirement in the initial links. Fixed-ratio 1 and 25 conditions were manipulated within subjects in… read more here.

Abstract: Highlights45 rats were classified in terms of their capacity of incentive salience attribution as sign‐trackers or goal‐trackers.Sign‐trackers and goal‐trackers were evaluated in the “suboptimal choice procedure”.Both groups were found to behave optimally.We found no evidence… read more here.

Abstract: Previous research has identified clear differences between pigeons and rats in the suboptimal choice procedure. Pigeons behave suboptimally, preferring an alternative with discriminative stimuli and a smaller probability of reinforcement, over another with a higher… read more here.

Abstract: As first reported several decades ago, pigeons (Columba livia) sometimes choose options that provide less food over options that provide more food. This behavior has been variously referred to as suboptimal, maladaptive, or paradoxical because… read more here.
