My research explores the evolutionary origins of the
human
mind by comparing the cognitive abilities of human and non-human
primates. It provides an interface between evolutionary biology,
developmental psychology and cognitive neuroscience. My experiments
focus on non-human primates (in captivity and in the field)
incorporating methodologies from cognitive development, animal learning
psychology, and cognitive neuroscience. My research examines the
following broad questions: what domains of knowledge are unique to the
human mind? Given that human infants and non-human primates both lack
language, what similarities and differences do we see in the expression
of non-linguistic domains of knowledge?
