An Animal Model of Human Gambling Based on Pigeon Suboptimal Choice
When humans gambling they choose an outcome that has high value but a low probability of occurrence over a more favourable high probability outcome of lower value (not gambling). Similarly, pigeons show a preference for an alternative that occasionally provides a signal for reinforcement over a more optimal alternative that always provides a signal for a lower probability of reinforcement. Two ...
متن کاملSuboptimal choice behavior by pigeons.
Contrary to the law of effect and optimal foraging theory, pigeons show suboptimal choice behavior by choosing an alternative that provides 20% reinforcement over another that provides 50% reinforcement. They choose the 20% reinforcement alternative--in which 20% of the time, that choice results in a stimulus that always predicts reinforcement, and 80% of the time, it results in another stimulu...
متن کاملSuboptimal Choice in Pigeons: Stimulus Value Predicts Choice over Frequencies
Pigeons have shown suboptimal gambling-like behavior when preferring a stimulus that infrequently signals reliable reinforcement over alternatives that provide greater reinforcement overall. As a mechanism for this behavior, recent research proposed that the stimulus value of alternatives with more reliable signals for reinforcement will be preferred relatively independently of their frequencie...
متن کاملImpulsivity affects suboptimal gambling-like choice by pigeons.
Pigeons prefer a low-probability, high-payoff but suboptimal alternative over a reliable low-payoff optimal alternative (i.e., one that results in more food). This finding is analogous to suboptimal human monetary gambling because in both cases there appears to be an overemphasis of the occurrence of the winning event (a jackpot) and an underemphasis of losing events. In the present research we...
متن کاملSuboptimal choice in a percentage-reinforcement procedure: effects of signal condition and terminal-link length.
Pigeons' choice between reliable (100%) and unreliable (50%) reinforcement was studied using a concurrent-chains procedure. Initial links were fixed-ratio 1 schedules, and terminal links were equal fixed-time schedules. The duration of the terminal links was varied across conditions. The terminal link on the reliable side always ended in food; the terminal link on the unreliable side ended with...
