    Technical Information

    Catherine Lord, Ph.D. 
    Catherine Lord, Ph.D. is a clinical psychologist whose research focuses on the development of children and adults with autistic spectrum disorders; including longitudinal studies of children referred for possible autism as toddlers, and, in collaboration with many colleagues, the development of instruments for the diagnosis of Autistic Spectrum Disorders and the quantification of social, communication and behavioral features associated with Autism and related developmental disabilities. These instruments have been important in providing standardized methods for research on the genetics and neurobiology of autism because they provide psychometrically valid and reliable tools for identification and specification of the behaviors that define autism. In addition, study of the process of diagnosis and of longitudinal change has provided intriguing insights into the nature of the social and behavioral deficits of these children.
