This book constitutes a timely contribution to the existing literature by presenting a relatively comprehensive, neurobiological account of certain aspects of second language acquisition. It represents the collaborative efforts of members of the Neurobiology of Language Research Group in the Applied Linguistics and TESL Department at UCLA. Members of the group are trained in neurobiology and then use this knowledge to develop biological accounts of various aspects of applied linguistics.
The volume avoids the corticocentric bias that characterizes many brain-language publications--both cortical and subcortical structures receive their appropriate attention. In addition, it demonstrates that enough is presently known about the brain to inform our conceptualizations of how humans acquire second languages, thus, it provides a refreshingly novel, highly integrative contribution to the (second) language acquisition literature.
The goal of the research program was based on the need to drawmore links between the neurobiological mechanisms and second language acquisition. As such, the book promotes a neurobiology of language that starts with the brain and moves to behavior. The fundamental insights presented should guide second language acquisition researchers for years to come.

The Interactional Instinct explores the evolution of language from the theoretical view that language could have emerged without a biologically instantiated Universal Grammar. In the first part of the book, the authors speculate that a hominid group with a lexicon of about 600 words could combine these items to make larger meanings. Combinations that are successfully produced, comprehended, and learned become part of the language. Any combination that is incompatible with human mental capacities is abandoned. The authors argue for the emergence of language structure through interaction constrained by human psychology and physiology.
In the second part of the book, the authors argue that language acquisition is based on an "interactional instinct" that emotionally entrains the infant on caregivers. This relationship provides children with a motivational and attentional mechanism that ensures their acquisition of language. In adult second language acquisition, the interactional instinct is no longer operating, but in some individuals with sufficient aptitude and motivation, successful second-language acquisition can be achieved.
The Interactional Instinct presents a theory of language based on linguistic, evolutionary, and biological evidence indicating that language is a culturally inherited artifact that requires no a priori hard wiring of linguistic knowledge.
