The purpose of this study was to compare learning and memory skills among three species of primates. Each of the studied species represented different branches of evolution: black-and-white ruffed lemur Varecia variegate –  the lemuriform primates; golden-bellied capuchin Sapajus xanthosternos – the New World monkey; Diana monkey Cercopithecus diana – the Old World monkey. The series of experiments which employed interactive platforms were the combination of behavioral training and observational study. The intent of the experiment was to measure the time it takes the object of the experiment to get the food (motivational factor) out of the interactive platform. Diana monkeys seem to possess the most evolved learning and memory skills of the three species studied in the experiment.
