Eight collared lizards were tested on a modified Lashley apparatus for brightness discrimination. The animals reached the criterion level of learning in 335 trials and exhibited behavior on the choice platform comparable to that of the rat presented with a similar problem. The pattern of latency appears to be atypical in the lizard, since there was little decrement throughout the learning period.
