Development of Nonverbal Behavior in the First Three Years of Life.
Iitaka, Kyoke; Yamada, Toshiko
This longitudinal study of the development of nonverbal behavior in the first 3 years of a child's life focuses on four factors: the relation between physical and vocal interaction between the child and his mother, observed cuses which can be used to interpret the child's communicative intent at different age levels, frequency of occurrence and possible communicative purpose of pointing behavior, and the developmental pattern in imitative behavior. The subject, an 11-month-old boy, was observed with his mother in a free play situation in weekly 30-minute sessions over 10 consecutive weeks at approximately 1, 2 and 3 years of age. Videotape recordings and checklists of six behavior categories (requesting, reporting, responding, imitative, manipulative, and explorative behaviors) were subsequently analyzed for two of the ten sessions at each age level. Results indicated that (1) in mother-child interaction, physical interaction predominated over vocal interaction at age 1, while verbal communication predominated at ages 2 and 3; (2) observers relied on auditory information in interpreting the communicative intent associated with physical actions at ages 2 and 3; (3) pointing behavior occurred most frequently at age 2, and was interpreted to mean "request" at age 1, and "report" at ages 2 and 3; and (4) imitative behavior exhibited qualitative change over the 3 years, gradually shifting from immediate imitation to deferred imitation.
