Primate Behavior and Ecology

Primate social psychology examines how species like chimpanzees, bonobos, and macaques form relationships, solve problems, make decisions, and navigate complex group life — drawing on both field observation and controlled experiments to understand the psychological mechanisms underlying these behaviors. Because humans are primates, studying our closest relatives offers a window into which cognitive and social capacities are ancient and shared versus which emerged more recently in our own lineage. Researchers have made significant progress linking brain size to social complexity, and documenting genuine altruism, empathy, and tool use across multiple species. Active debates center on how deeply primate cognition resembles human reasoning — whether, for instance, other apes hold genuine mental models of what others know and want — and how ecological pressures and social structure jointly shape the evolution of intelligence.
