Abstract
Three groups of 40 Ss predicted the occurrence of reinforcing lights differing in luminance in an Estes & Straughan (1954) probability-learning situation. Little effect of luminance difference was found. It was concluded that the luminance effect reported by Nazzaro & Todorov (1966) is, at most, a weak effect in this situation.
