Research over the past four decades has built a convincing case that co-speech hand gestures play a powerful role in human cognition . However, this recent focus on the cognitive function of gesture has, to a large extent, overlooked its emotional role-a role that was once central to research on bodily expression. In the present review, we first give a brief summary of the wealth of research demonstrating the cognitive function of co-speech gestures in language acquisition, learning, and thinking. Building on this foundation, we revisit the emotional function of gesture across a wide range of communicative contexts, from clinical to artistic to educational, and spanning diverse fields, from cognitive neuroscience to linguistics to affective science. Bridging the cognitive and emotional functions of gesture highlights promising avenues of research that have varied practical and theoretical implications for human-machine interactions, therapeutic interventions, language evolution, embodied cognition, and more.
