The Reorganization of Communicative Behaviors around the Onset of the Vocabulary Spurt: A Dynamic Systems Approach.
Master's Thesis, University of Pittsburgh.
(Unpublished)
Abstract
This study investigated the reorganization of communicative behaviors during the window of time surrounding the vocabulary spurt by considering the relationship between language, gesture, and affect as the communicative system undergoes a period of instability. Eighteen typically developing infants were videotaped with a primary caregiver at home one month before, at, and one month after the onset of the vocabulary spurt. There were significant differences between the vocabulary spurt session and surrounding sessions in terms of the production and temporal patterning of expressive behaviors. Specifically, the coordination of communicative behaviors occurred less frequently; speech was particularly unlikely to appear in coordination with other behaviors; and the use of earlier well-practiced configurations (e.g., affect combined with meaningless vocalizations) increased specifically at the spurt session. In addition, infants who experienced a more dramatic transition in vocabulary development showed evidence of greater system-wide instability at the vocabulary spurt onset. Findings underscore the importance of examining the communicative system as a whole and using a milestone-based dynamic systems approach to studying developmental change.
