Axelrod, S., Leiber, L. & Noonan, M.  Classification of random forms and distortions presented to the left or right visual field.  Perceptual & Motor Skills, 1978, 47, 615-621.

Summary.—Twenty right-handed undergraduate men were taught in free vision to categorize distortions of prototypic random forms and were then tested in a Go/No Go task with lateralized tachistoscopic presentations of previously sorted (old) distortions, new distortions, the prototypes, and unrelated forms.  Accuracy of performance on positive items increased in the order New < Old < Prototype.  More false alarms occurred to unrelated items in the right than in the left visual field, suggesting that the trace systems generated during training had different characteristics in the two hemispheres.
