This book "asserts that the origin and spread of languages must be examined primarily through the time-tested techniques of linguistic analysis, rather than those of evolutionary biology" and "defends traditional practices in historical linguistics while remaining open to new techniques, including computational methods" and "will appeal to readers interested in world history and world geography."
This book explores an understudied area of language development in autism – namely, how children with autism learn the meaning of verbs. The key feature is a profile of verb acquisition in autism derived from qualitative analysis of the conversational language of ten children with autism. Douglas examines whether this profile is typical or atypical compared with verb learning in neurotypical children. Verb use is central to linguistic development, and the ability of children with autism to develop and use verb categories is of interest, because verbs also encode information about the number and type of participants and the temporal location of the activity/event. Moreover, the acquisition of verb meanings is often dependent on other cognitive skills, such as the recognition that human beings have beliefs and desires which motivate their actions. All these are areas which are widely considered problematic for children with autism and continue to generate much discussion among researchers and clinicians. This investigation is among the first studies of its type, offering new insights into the process of language acquisition in autism.
