Michael Tomasello

This Monograph reports a series of ten studies on the social-cognitive abilities of three young chimpanzees, ages to four years. Compares outcomes to similar studies conducted on human infacts for a comparative understanding. Looks at chimpanzees' abilities to understand and imitate goal-directed actions. Results suggest that the ontogeny of human social cognition comprises two relatively distinct trajectories: one for understanding intentional action and perception, common to all apes, and another for sharing psychological states with others in collaborative acts involving joint intentions and attentions, unique to the human species.

During the second year of his daughter's life, Michael Tomasello kept a detailed diary of her language, creating a rich database. He made a careful study of how she acquired her first verbs and analysed the role that verbs played in her early grammatical development. Using a Cognitive Linguistics framework, the author argues persuasively that the child's earliest grammatical organization is verb-specific (the Verb Island hypothesis). He argues further that early language is acquired by means of very general cognitive and social-cognitive processes, especially event structures and cultural learning. The richness of the database and the analytical tools used make First Verbs a particularly useful and important book for developmental psychologists, linguists, language development researchers and speech pathologists.

In this groundbreaking book, Michael Tomasello presents a comprehensive usage-based theory of language acquisition. Drawing together a vast body of empirical research in cognitive science, linguistics, and developmental psychology, Tomasello demonstrates that we don’t need a self-contained “language instinct” to explain how children learn language. Their linguistic ability is interwoven with other cognitive abilities. Tomasello argues that the essence of language is its symbolic dimension, which rests on the uniquely human ability to comprehend intention. Grammar emerges as the speakers of a language create linguistic constructions out of recurring sequences of symbols; children pick up these patterns in the buzz of words they hear around them. All theories of language acquisition assume these fundamental skills of intention-reading and pattern-finding. Some formal linguistic theories posit a second set of acquisition processes to connect somehow with an innate universal grammar. But these extra processes, Tomasello argues, are completely unnecessary—important to save a theory but not to explain the phenomenon. For all its empirical weaknesses, Chomskian generative grammar has ruled the linguistic world for forty years. Constructing a Language offers a compellingly argued, psychologically sound new vision for the study of language acquisition.

Ambitious and elegant, this book builds a bridge between evolutionary theory and cultural psychology. Michael Tomasello is one of the very few people to have done systematic research on the cognitive capacities of both nonhuman primates and human children. The Cultural Origins of Human Cognition identifies what the differences are, and suggests where they might have come from. Tomasello argues that the roots of the human capacity for symbol-based culture, and the kind of psychological development that takes place within it, are based in a cluster of uniquely human cognitive capacities that emerge early in human ontogeny. These include capacities for sharing attention with other persons; for understanding that others have intentions of their own; and for imitating, not just what someone else does, but what someone else has intended to do. In his discussions of language, symbolic representation, and cognitive development, Tomasello describes with authority and ingenuity the "ratchet effect" of these capacities working over evolutionary and historical time to create the kind of cultural artifacts and settings within which each new generation of children develops. He also proposes a novel hypothesis, based on processes of social cognition and cultural evolution, about what makes the cognitive representations of humans different from those of other primates. Lucid, erudite, and passionate, The Cultural Origins of Human Cognition will be essential reading for developmental psychology, animal behavior, and cultural psychology.
