Acquisition of observing responses with delayed conditioned reinforcement
Six pigeons were trained to key peck for 3-s access to mixed grain on a multiple variable-interval 60-s extinction schedule. The schedule then was changed to a mixed variable-interval 60-s extinction schedule. Simultaneously, a treadle was introduced into the chamber. For 3 pigeons, the stimulus …

Variables controlling the resurgence of previously reinforced behaviour in hens
… and behaviours were selected from door push, key peck, and head bob. In Experiment 1, using 6 naive hens, Behaviour 1 was reinforced on a random-interval (RI) 60-s schedule followed by two sessions of extinction. Each occurrence of Behaviour 2 was then reinforced followed by another period of …

Reflexivity: A first demonstration
<p>Currently, the emergent relation of reflexivity after training a set of baseline relations has not been demonstrated with any animal—human or nonhuman. True reflexivity can only be demonstrated if no identity (i.e., physically matching stimulus) relations are trained. In six experiments, the …

Generalized identity matching in the pigeon: Effects of extended observing- and choice-response requirements.
Four experimentally naïve white Carneau pigeons learned to match three colors to each other in a variant of an Identity matching-to-sample procedure with an FR20 on samples and a response-initiated FI8-s on comparisons. In Experiment 1, the extent to which subjects were matching on the basis of …
