towards speech. The author emphasizes that a child's trouble can stem from different causes: there are neurological problems similar to those of aphasia; there are cognitive impairments; and, of course, there are psychological disorders. Professor Danon-Boileau argues that language disorderstoday are too often considered from one particular point of view-sometimes psychological, sometimes neurological. In order to understand the possible causes of, and solutions to, these disorders, it is necessary to take into account the interaction of these two elements. Those who have effectivelyworked with speechless children know all too well that their pathology and behaviour do not necessarily fit into general nosographic descriptive categories.The originality of this book is that it gives a concrete and precise narrative of six individual case studies and tries to draw general conclusions from both a linguistic and a psychoanalytic point of view, thus reflecting the wide-ranging expertise of the author. It will be essential reading forprofessionals within the field of psychoanalysis and speech therapy; academics and students in language acquisition, speech therapy, and developmental psychology; as well as parents who are concerned with their children's language development.
