Project Description

Data analyzed for this study were collected as a part of a longitudinal project tracking early normal speech development from the onset of canonical babbling through age 3.5 years. Subjects were located by informal referral from the surrounding community. Normal development was established through parent case history report. In addition, each infant was administered the Battelle Developmental Screening Inventory (Guidubaldi, Newborg, Stock, Svinicki, & Wneck, 1984) and hearing screening using sound field techniques.

Video and audio recordings were gathered in the children’s homes during natural interactions and situations that occurred in their daily lives. The children were interacting with their parent or others present in their home setting. The experimenter sometimes interacted with the child and parent and sometimes observed as seemed natural in the setting.
