Journal of Experimental Psychology Animal Behavior Processes
Eight pigeons were trained on a go-no go visual discrimination involving 1 S + and 15 S s. The 16 discriminative stimuli were black-and-white line drawings created by the factorial combination of 4 different geometric shapes (wedge, cylinder, cone, handle) in 4 different spatial locations (right, left, above, below) in relation to a common shape (cube).
