Abstract
Testing sensory characteristics on herpetological species has been difficult due to a range of properties related to physiology, responsiveness, performance ability, and the type of reinforcer used. Using the Jacky lizard as a model, we outline a successfully established procedure in which to test the visual sensitivity to motion characteristics. We incorporated modifications to traditional operant paradigms by using three video playback systems to deliver random-dot kinematogram motion stimuli coupled with salient computer-animated secondary reinforcers representative of biologically important appetitive stimuli. This procedure has the capacity to test other visual aspects in lizards as well as other nonhuman species using video playback and computer-animation techniques as experimental tools.
