Abstract
Three groups of pigeons were trained to peck at a white vertical line on a yellowish-green surround for variable-interval reinforcement and were then tested for generalization, in extinction, along the wavelength dimension (Group B, N=10), the angularity dimension (Group C, N=10), or along both dimensions presented separately and in alternating sequence (Group A, N = 20). Group A produced both absolute and relative gradients comparable to those obtained from Groups B and C. Several prior studies have similarly failed to find successive contextual effects in generalization testing in pigeons.
