Interocular generalization: a study of mirror-image reversal following monocular discrimination training in the pigeon. 1966

N K Mello

Generalization gradients along a continuum of angular orientation were obtained from four pigeons, following monocular training on a discrimination between a 45 degrees oblique line (S+) and a 135 degrees oblique line (S-). All pigeons were trained on a chain DRO VI 1 schedule of reinforcement. Generalization gradients obtained with the trained and untrained eye were compared. All pigeons responded maximally to the 45 degrees line (S+) when tested with only the trained eye open. During generalization tests of interocular transfer with only the untrained eye open, three pigeons responded maximally to S- (135 degrees ), the mirror-image of the stimulus associated with reinforcement during training (45 degrees ). The other pigeon failed to show interocular transfer of the discrimination. Interocular reversal of left-right mirror-image stimuli has not been reported for any other species.

D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
