摘要

Gambling disorder is characterized by a maladaptive behavioral pattern that persists despite significant negative consequences. Neuropsychological paradigms such as the Iowa Gambling Task (IGT) and its adaptation to animal models, have provided critical insights into the mechanisms underlying this type of decision-making. In the present report, we introduce an adaptation of the IGT for pigeons, to determine whether the pigeons’ suboptimality that has been found in other choice tasks extends to this paradigm, a result that would point toward a generalized suboptimal-choice profile in this species. The IGT’s results were compared to those obtained with rats and with human participants, observing that pigeons exhibit a predominantly optimal pattern, with inter-individual variability consistent with other species. These results validate the implementation of the IGT for pigeons as a robust model. Finally, based on the analysis of individual-performance differences in the IGT, we suggest future research directions for understanding them, and propose the use of the present findings as a baseline to explore the relationship between maladaptive behavior and key variables involved in gambling-like behavior in pigeons and in other species.
