The Emergence of Symmetry in a Conditional Discrimination Task Using Different Responses as Propioceptive Samples in Pigeons
Peer reviewed Peer reviewed
Direct linkDirect link
Garcia, Andres; Benjumea, Santiago – Journal of the Experimental Analysis of Behavior, 2006
In Experiment 1, 10 pigeons were exposed to a successive symbolic matching-to-sample procedure in which the sample was generated by the pigeons' own behavior. Each trial began with both response keys illuminated white, one being the "correct" key and the other the "incorrect" key. The pigeons had no way of discriminating which key was correct and…

On the Effects of Signaling Reinforcer Probability and Magnitude in Delayed Matching to Sample
Peer reviewed Peer reviewed
Direct linkDirect link
Brown, Glenn S.; White, K. Geoffrey – Journal of the Experimental Analysis of Behavior, 2005
Two experiments examined whether postsample signals of reinforcer probability or magnitude affected the accuracy of delayed matching to sample in pigeons. On each trial, red or green choice responses that matched red or green stimuli seen shortly before a variable retention interval were reinforced with wheat access. In Experiment 1, the…
