| Abstrakt: |
Several developing behaviors of a single infant are tracked via direct and continuous measurement through the period of acquisition and decay of these behaviors. Changes in frequency and duration are reported for four motor behaviors, and frequency changes for speech and nonspeech sounds. The relationship of changes in vocal behavior as motor skills are emerging is also explored. |
