Summary

Chelonia (turtles, terrapins and tortoises) have traditionally been considered to be “sluggish and unintelligent creatures” (Yerkes 1901, p. 520) and have largely been ignored in the study of animal cognition. However, more recent research has revealed an impressive suite of cognitive abilities in this group. But how do you ask a tortoise what it knows? We will describe the approaches we have thus far taken in the study of cognition in our model species, the red-footed tortoise (Chelonoidis carbonaria) – including work on visual cognition, spatial cognition, social learning and memory –, examining pros and cons. This chapter will subsequently discuss general issues related to working with chelonia, such as temperature and motivation: testing a tropical tortoise in a cold room, for instance, fundamentally impacts the ability of the tortoise to demonstrate its cognitive abilities. Chelonia are not necessarily motivated by the same things as mammals and different species may be motivated by different rewards, necessitating a thorough understanding of the species before embarking on experiments. We finish with an overview of techniques that we have used for investigating cognition in this species.
