Visual abilities to discriminate between spatial and color stimuli was studied, which is ecologically significant for reptiles. Namely: the behavior of slow-warm lizards in a Tshaped maze was investigated in visual discrimination between red and green color tones and sizes of geometric figures of a round shape. The main behavioral characteristics of decisionmaking were analyzed when choosing between possible options: a percentage of erroneous choices, time of choice and a number of lizards’ turns towards alternative ways in the maze, leading to comparable stimuli, before choosing one of them. In case of color discrimination, all the three named behavior characteristics were minimal, while in case of the figures sizes discrimination these values were higher. Thus, discrimination of red and green colors was more successful and less difficult than discrimination of round-shaped geometric figures sizes in the lizards.
