This dissertation investigated the caregiving relationships between infants and nonparental caregivers in early childcare settings through the lens of attachment and language behaviors. This study sought to provide an opportunity to extend our understanding of the socioemotional factors that influence children's development in their daily lives.…

The study aims to account for the distribution of finite versus non-finite verbs during a developmental period when children use both types of verb forms in contexts requiring finiteness. To meet this goal, longitudinal samples from three Hebrew-acquiring children (aged 1;4-2;6) are examined from the onset of verb production and across the…

Observation of five infants' vocalizations during their first 30 weeks showed that hearing impaired infants displayed different language patterns than normally hearing infants. Developmental differences in vocal activity were observed by six weeks, suggesting that hearing impaired infants may differ from unimpaired infants earlier than has been…

Purpose: This study tests the hypothesis that toddlers with autism spectrum disorders (ASD) will show differences from contrast groups in preferences for attending to speech. Method: This study examined auditory preferences in toddlers with ASD and matched groups of (a) typical age-mates, (b) age-mates with nonautistic developmental disabilities,…

An investigation of the nature of one, 2-year-old child's imitative competence in using the modal auxiliary system of English (using "will" and "can") during two periods two months apart. (ED)

This study examined the effects of being born very preterm on children's early language development using prospective longitudinal data from a representative regional cohort of 90 children born very preterm (gestational age less than 33 weeks and/or birth weight less than 1,500 grams) and a comparison sample of 102 children born full term…

Describes the various direct and indirect effects of HIV and AIDS on children's development and the implications for early intervention assessment. HIV and AIDS effects include disorganization during the neonatal period, failure to thrive, motor difficulties, cognitive dysfunction, expressive language behavior, attention problems, and…

This study reports a replication of an earlier study by Kilbourne and Ginsberg (1980) which indicated the occurrence of a transition from predominantly coacting to predominantly alternating infant-mother vocalization patterns. In addition, the present study examined the modulating influences of nursing activity and mother's focus of attention upon…

Video-analysis was used to investigate the transition from coacting to alternating patterns of infant-mother vocalizations in this longitudinal study of one infant. In addition to investigating the transition and its developmental implications, the relationship between the temporal patterning of kinesic and vocal behaviors was studied. The study…

Describes a study done to determine whether the degree of children's familiarity with component words was related to (1) their ability to produce productive patterns as opposed to associative and grouping patterns, and (2) their ability to use broader scope rather than lexically based patterns. (SED)

Examined infants' tendency, from a few days to nine months of age, to prefer infant-directed over adult-directed speech. Results suggest that exaggerated pitch contours that characterize infant-directed speech may become salient communicative signals for infants through language-rich, interactive experiences with caretakers and increased…

The development of the Conversational Unit (CU) was investigated in a semilongitudinal study of three mother/son dyads in nonstructured spontaneous communication. The children were 19 to 23 months old at the start of the investigation. Sound films were recorded monthly during bathing and feeding times. After four months, verbal and nonverbal…
