Imitation has long intrigued students of human nature, because it is both pervasive in human life and a channel connecting the individual mind to the social and cultural context in which it lives. There is a recent resurgence of interest in imitation among investigators of cognition and perception, cognitive neuroscience, human development and comparative cognition [1]. A number of groundbreaking discoveries across these domains have led to the converging conclusion that imitation and the processes by which it occurs offer a unique window to the mind. Building on this synergy, Meltzoff and Prinz have assembled a volume that both illustrates the growing breadth of interest in imitation and distills the core questions that surface across disciplines. These questions concern the level at which action is represented and the system that relates self-produced actions to the observed actions of others. A critical insight emerging throughout the book is that behavior can be imitated at various levels, from specific motor patterns to the more abstract goals that guide action. This insight informs debates about whether, when and why reproducing the specific motor details of an action are crucial (see Refs [2, 3], as well as the chapters by Byrne, Gattis and colleagues, Meltzoff, and Whiten). This insight also shows that imitation can be used to investigate action representations. Many chapters of the book illustrate this method, converging on the conclusion that actions are represented beyond the level of motor patterns: the various authors demonstrate that adults and children (Bekkering, Gattis and colleagues, Prinz, Vogt), infants (Meltzoff), and non-human primates (Byrne, Whiten) represent action in terms of its goal structure. As Tversky and colleagues elucidate, goal-directed action is richly structured. Some aspects of this structure are represented at different points in ontogeny, in different species, or in different situations. The book provides initial insights into these more specific aspects of action representation, including the ability to interpret the same motor pattern flexibly based on an analysis of the actor’s goals (Decety, Gattis and colleagues, Prinz), sensitivity to the hierarchical and sequential structure of action (Byrne, Whiten), and the ability to anticipate the outcome of an incomplete action (Jellema and colleagues, Meltzoff). Imitation rests on the ability to relate one’s own actions to the actions of others. Throughout the book there is converging evidence for an important insight into this process–that observed and self-produced behaviors are united by common neurocognitive representations. Elegant behavioral research has shown that producing a particular action and perceiving that action draw on some of the same representational resources (Bekkering, Prinz, Vogt). Moreover, recent findings have revealed neural substrates (so-called ‘mirror neurons’) that respond to both observed actions and self-produced actions (Decety, Rizzolatti and colleagues). These findings yield important insights into perception–action relations, the production of voluntary behavior, and neural architecture. Crucially, they also indicate that imitation can result directly from the activation of these common representations, requiring no translation to account for the match between actions perceived and actions performed. This activation would be maladaptive if it were expressed for all actions. Several authors propose mechanisms for the modulation of imitative behavior (Bekkering, Decety, Kinsbourne, Rizzolatti and colleagues), and several consider instances in which this modulation fails to occur–in infancy (Decety, Kinsbourne, Heimann), in autism (Nadel, Whiten), and in certain cases of …
