Technique for measuring speed and visual motion sensitivity in lizards

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
