'At last here is a volume that provides a compelling answer to the question of what is 'social' about social cognition. The editors have assembled a stellar cast of social psychology researchers to address this question head-on and the result is eye-opening and mind-expanding. From intraindividual to interpersonal to group processes, the consistent message throughout the chapters of the volume is that of the inextricable connections between human cognition and social behavior. Empirically and conceptually the contributors to this project make a convincing case that, for human beings, mental life is social life.' Marilynn B. Brewer, Ohio State University
