The behavioral task used to study movie performance. The subject performed a delayed match-to-sample task and had to indicate (by releasing a lever) whether sample and test stimuli were identical matches. If the sample and test were not identical, the subject had to wait until a 3rd stimulus was presented, which was always an identical match to the sample (and required a lever release). Sample and test stimuli were both high-contrast, random-dot movies on a gray background. The location of the receptive field (RF) of a neuron is indicated by the dotted yellow circle.
