Final Syllable Lengthening (FSL) has been extensively examined in infant vocalizations in order to determine whether its basis is biological or learned. Findings suggest there may be a U-shaped developmental trajectory for FSL. The present study sought to verify this pattern and to determine whether vocal maturity and deafness influence FSL. Eight normally hearing infants, aged 0 ; 3 to 1 ; 0, and eight deaf infants, aged 0 ; 8 to 4 ; 0, were examined at three levels of prelinguistic vocal development: precanonical, canonical, and postcanonical. FSL was found at all three levels suggesting a biological basis for this phenomenon. Individual variability was, however, considerable. Reduction in the magnitude of FSL across the three sessions provided some support for a downward trend for FSL in infancy. Findings further indicated that auditory deprivation can significantly affect temporal aspects of infant speech production.

This study focuses on the impact of a clinic-based intervention program on the immunization status of limited-income urban children. The intervention program consisted of an information session for clinic health care providers and the placement of individualized immunization information labels on clinic notes at the time of each visit. The degree of impact of the intervention on immunization administration was ascertained through a comparison of two similar groups of infants born in the same months of the year immediately before (N = 201) and after (N = 203) the information session and initiation of the labeling system. The timeliness of administration of each diphtheria, pertussis, tetanus and trivalent oral polio vaccine (DPT/TOPV) in the first year series of three was compared pre- to postintervention. Significantly more third immunizations were given the postintervention subjects within ten days of the recommended time of application ( p = .0361). Life table analysis indicated that the probability of an infant's passing one year of age without the administration of the third immunization decreased for postintervention infants (p = .0515). The intervention was most successful in assuring administration of the series of immunizations in those infants who were seen by the health care provider for at least 50% of their first year visits. Results indicate that minor changes in the format of information given a relatively continuous provider can increase completion of immunization series in infants. ^
