The CDI: Words and Gestures Forms are for children ages 8â "18 months. In the form, the first part prompts parents to document the childâ (TM)s understanding of hundreds of early vocabulary items separated into semantic categories such as animal names, household items, and action words. Parents mark the words understood or used, and the forms yield separate indexes of words understood and words produced. The second part of each form asks parents to record the communicative and symbolic gestures the child has tried or completed.
These forms are part of the MacArthur-Bates Communicative Development Inventories (CDIs). The CDIs and their Spanish adaptation, the Inventarios, are standardized, parent-completed report forms that track young children's language and communication skills. Top language researchers developed the report forms, designing them to focus on current behaviors and salient emergent behaviors that parents can recognize and track.

Her most recent work focuses on the identification of precursors of language delay and individual differences in lexical and morphological development in monolingual English and bilingual (Spanish and English) speakers. She is on the editorial board of the Journal of Speech, Language, and Hearing Research and was named Distinguished Scholar at the Callier Center for Communication Disorders. Dr. Marchman has worked on the MacArthur Communicative Development Inventories and the MacArthur Inventarios del Desarrollo de Habilidades Comunicativas for the last 15 years.

With strengths in developmental psychology, linguistics, neurology, and cognitive science, she carried out many creative and influential collaborative studies on the interrelations among language acquisition, brain function, symbolic growth, and other key aspects of development. During her extensive career, she directed cross-linguistic studies on 4 continents and authored or co-authored 10 books and more than 200 scientific publications. Her work was interdisciplinary, influencing diverse fields such as neuroscience, linguistics, biology, psychology, computer science, and medicine.
