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.…

Onomatopoeia are frequently identified amongst infants' earliest words (Menn & Vihman, 2011), yet few authors have considered why this might be, and even fewer have explored this phenomenon empirically. Here we analyze mothers' production of onomatopoeia in infant-directed speech (IDS) to provide an input-based perspective on these forms.…

The present dissertation extracted 17,291 questions from Aki, Ryo, and Tai and their mother's spontaneously produced speech data available in the CHILDES database (MacWhinney, 2000; Oshima-Takane & MacWhinney, 1998). The children's age ranged from 1;3 to 3;0. Their questions were coded for (1) yes/no questions that include a sentence-final…

Infant-parent play with toys is an early form of social communication, and the toy features (i.e., affordances), as well as the child's language competence, contribute to the developmental level of the play and the types of play actions that occur. This research, conducted in cooperation with a toy manufacturer, investigated how the affordances of…

The phonetic characteristics of canonical babbling produced by Korean- and English-learning infants were compared with consonant and vowel frequencies observed in infant-directed speech produced by Korean- and English-speaking mothers. For infant output, babbling samples from six Korean-learning infants were compared with an existing English…

The study sought to isolate and identify patterns occurring in language interactions between mothers and their nonhandicapped and Down Syndrome children. Data were collected as part of a 3-year study of language interaction. Twenty nonhandicapped (NH) and 20 Down Syndrome (DS) children and their mothers were evaluated via a demographic inventory,…

Investigation of French mothers' (N=6) use of pronouns to refer to their infants during free play showed that third- and first-person pronouns occurred more often in the context of affect-oriented activities than in goal-directed activities. Second-person pronoun usage occurred more frequently in goal-directed activities. (Author/CB)

Measures fathers' and mothers' linguistic involvement in the development of communication between young siblings--infants and toddlers. In a laboratory setting, 39 families, each with a mother, a father and two children, were videotaped in semistructured activities. Results suggest that fathers very actively direct sibling interactions, especially…

A longitudinal study of twenty-four (24) Hebrew-speaking mother-infant dyads during discussions of recent events indicated that mothers commented on a small set of events and tended to mark events with exclamations or formulaic expressions that gradually progressed to a true description of events as the children got older. (Author/CB)

Microanalyses of unstructured videotaped interactions of three mother-infant dyads revealed dramatic shifts in dyadic vocalization patterns from primarily overlapping to primarily alternating. These results suggest that the emergent patterns reflect increased potential for coordination within the dyad, which may be capitalized on by mother and…

Discusses the modifications in the direction of simplified and more linear language (American Sign Language) used by deaf mothers with their deaf children. (EKN)

Examines whether vocal exchanges between preverbal infants and their mothers show characteristics similar to those found to be typical of conversational exchanges between competent adult speakers. (HOD)

Examination of the speech of eight mothers and eight fathers to their one- to two-year-olds (N=8) indicated that, while paternal speech was not more diverse than maternal speech, paternal speech did show greater use of rare vocabulary and lower use of common vocabulary. (Author/CB)

Examines naturalistic adult-to-child speech of Italian middle class mothers to determine which patterns characterize linguistic input to infants. Because Italian is a pro-drop language, adult-to-child speech revealed bias toward more salient semantic and morphological significance of verbs relative to nouns, and verbs will likely occupy…

Reports results of a longitudinal study of the acquisition of first words by 18 infants. Strategies used in word acquisition and environmental variables related to language development were investigated. Results were analyzed in terms of an interaction model of the language-learning process. (DP)
