In the visual alternation task, pigeons learn to alternate between two stimuli (e.g., red and green) that vary randomly in location from trial to trial. The task is inherently difficult because animals tend to return to a stimulus to which they have

Same/different abstract concept learning in pigeons is typically assessed by training subjects with one set of stimuli and demonstrating that they can transfer that learning to new stimuli. Converging evidence suggests that under a variety of conditi

The ephemeral-reward task involves providing subjects a choice between two distinctive stimuli, A and B, each containing an identical reward. If A is chosen, the food associated with A is obtained ...

RATIONALE: Laboratory experiments often model risk through a choice between a large, uncertain (LU) reward against a small, certain (SC) reward as an index of an individual’s risk tolerance. An important factor generally lacking from these procedur

There is evidence that impulsive decision-making is associated with errors in timing. However, there has been little attempt to identify the putative mechanism responsible for impulsive animals' timing errors. One means of manipulating impulsivity in

It is well known that when humans are given a choice between two options, their preference is affected by the presence of a third. Generally, there is an increase in preference for the option closer to the third. We show that a shift in preference in

Slot machines are among the most popular forms of commercial gambling, and the high frequency of losses that come close to winning – near hits – in this game appears to contribute to its popularity. In the present experiment we tested if pigeons,

Stimuli that are more predictive of subsequent reward also function as better conditioned reinforcers. Moreover, stimuli attributed with incentive salience function as more robust conditioned reinforcers. Some theories have suggested that conditioned

Human gambling generally involves suboptimal choice because the expected return is usually less than the investment. We have found that animals, too, choose suboptimally under similar choice conditions. Pigeons, like human gamblers, show an impaired

Pigeons were tested for their ability to report the location they recently pecked, without prior experience having to do so. They were first pretrained to report the location that they had just pecked. They were then trained on a conditional discrimi
