Special Issue: Space, Time and Number Origins of spatial, temporal and numerical cognition: Insights from comparative psychology

Abstract

Contemporary comparative cognition has a large repertoire of animal models and methods, with concurrent theoretical advances that are providing initial answers to crucial questions about human cognition. What cognitive traits are uniquely human? What are the speciestypical inherited predispositions of the human mind? What is the human mind capable of without certain types of specific experiences with the surrounding environment? Here, we review recent findings from the domains of space, time and number cognition. These findings are produced using different comparative methodologies relying on different animal species, namely birds and non-human great apes. The study of these species not only reveals the range of cognitive abilities across vertebrates, but also increases our understanding of human cognition in crucial ways. Researching human cognition through the study of other species 'He who understands baboon would do more towards Metaphysics than Locke' (Charles Darwin, 1838, Notebook M84e) In this short note, 21 years before publication of the Origin of Species, Charles Darwin recognised the value of studying animal cognition for human psychology. Implicit here is the idea that cognitive processes are biological adaptations with evolutionary histories and, therefore, cognition is tractable to between-species mapping of similarities and differences in cognitive abilities. The past two decades have seen an increase in the number of species studied and the types of methodological approaches used in the growing field of comparative cognition Are some cognitive capacities in place at birth? Rigorous controlled-rearing experiments with non-human animals enabled scientists to establish what mechanisms are present at birth and the impact of specific experiences on shaping basic perceptual-motor capacities 552 1364-6613/$ -see front matter
