About

William D. Hopkins is a leading figure in comparative psychology and primatology, whose work has fundamentally shaped our understanding of primate cognition, brain lateralization, and social behavior. His research primarily explores the evolutionary origins of human cognitive abilities, with a particular focus on chimpanzees and other great apes. Hopkins’s major contributions include pioneering studies on handedness and its relationship to brain asymmetry, demonstrating that non-human primates exhibit population-level handedness for skilled tasks, a trait once thought uniquely human. He has also extensively investigated mirror self-recognition, tool use, and gestural communication, revealing complex social and cognitive capacities in apes. Among his notable works, his 2013 study on chimpanzee responses to a humanoid robot—showing that apes can initiate social interactions and request responses from an artificial agent—garnered significant attention (26 citations) for its implications for animal-machine interaction and social cognition. With over 300 publications and thousands of citations, Hopkins has profoundly influenced debates on the evolution of language, social learning, and the neural underpinnings of behavior, making his research essential reading for students and scholars in evolutionary psychology, neuroscience, and animal behavior.
