1) The study tested whether three species of monitor lizards (Varanus spp.) showed evidence of association learning by recording how long it took them to locate food over repeated trials. 2) Results showed that the time to locate food decreased with the number of trials for two of the three species, providing evidence of association learning. 3) The study suggests that an active foraging lifestyle may place greater cognitive demands on monitor lizards and help explain their ability to learn associations through experience.
