Computer-aided spatiotemporal imaging techniques, like those that are proving to be important in many other scientific fields, are being used to represent and study movement patterns of animals exposed to basic reinforcement contingencies. Data from a video-tracking system that provides real-time tracking of the position of an experimental animal as it moves about in a threedimensional space can be plotted in up to three dimensions. When the data are plotted in two spatial dimensions and the time dimension, behavior is captured as continuous patterns or structures in space-time. Spatiotemporal imaging of movement patterns permits regularities to be observed that are not seen as readily in other ways such as watching videotapes of the experimental sessions or simply examining rate of responding. By providing a concise spatiotemporal representation of the movement patterns that occurred in a givet~ experimental preparation, the imaging techniques described here represent an advancement in the scientific study of continuously flowing behavior. Although we concentrate here on movement patterns produced by basic reinforcement contingencies, the spatiotemporal imaging technology is applicable to any research topic in which movement patterns are of interest, such as foraging, place learning, sign language, and limb movement.
