This article focuses on early intervention implementation concerns and recommendations for addressing the needs of the wide range of infants and toddlers with disabilities and families to be served. It describes providing services in natural environments, as well as the issues of personnel preparation and models of service delivery. (Contains…

Relationships between pretend play and word production were investigated in 10 hearing toddlers and 10 toddlers with hearing loss who attended an auditory/oral early intervention program. Results showed significantly higher levels of pretend play for the hearing children and an association between level of pretend play and word production for the…

This case study traces responses of one child to a program of music experiences implemented in the toddler playroom of a day care center for 10 months. The program used three types of music experience: free music play, sociable music experiences, and music incorporated into caregiving routines. Findings highlight how music activities can enhance a…

Two experiments investigated the Aspect First Hypothesis, which claims children initially use verbal morphology to mark aspect and not tense. The first tested 46 2- and 3-year-old children's comprehension of tense as it is marked in the auxiliary system using a sentence-to-scene matching task. The second changed the information available in the…

The internal reliability and concurrent validity of the Play Assessment Questionnaire (PAQ) was compared to that of the Minnesota Child Development Inventory with 170 deaf or hard of hearing infants and toddlers. The PAQ was found to be a useful nonverbal tool that assesses symbolic play behaviors and demonstrates a parallel development with…

Notes that scientists understand in greater detail the various anatomical and neurological changes that allow children to develop motor and sensory abilities. Explores how the research findings are calling into question the notion of prescribed developmental milestones. (HTH)

Compared the proportions of nouns and verbs in early vocabularies of English- and Mandarin-speaking toddlers and their mothers. Found that Mandarin-speaking children had relatively fewer nouns and more verbs than English-speaking children. When reading books, children's vocabularies were dominated by nouns but not when playing with toys. Mothers…

Compared the impact of a small box emitting sounds in response to nearby motion introduced into an infant/toddler and a preschool classroom to illustrate qualitative differences in how children of different ages recognize the same objects as mediating devices for activity. Found that the box became a social object for infants/toddlers and part of…

Compared food texture preferences during infancy and toddlerhood. Found that infants displayed more negative expressions and head and body movements in response to complex textures than to simple textures. Toddlers displayed more positive head and body movements and more eagerness in response to complex than to simple textures. Experience with…

Prelinguistic children (N=58) with developmental delay received one of two staff-implemented treatments designed to increase intentional communication ability. Results confirmed the prediction that treatment effects on children's receptive and expressive language 6 and 12 months after intervention would vary as a function of pretreatment maternal…

Presents emergentist coalition theory of language development characterizing lexical acquisition as the emergent product of cognitive constraints, social-pragmatic factors, and global attentional mechanisms. Details 12 experiments with 12- to 25-month-olds using the development of reference as test case of the theory. Presents evidence that…

Describes the richness of Hollich et al.'s model of language acquisition. Presents concerns about focus on object words in word learning research, the phantom child in the model, and the missing affect in theories and research on word learning. Suggests that experimental work inspired by principles and constraints theory and observational work…

Investigated in 3 studies whether 2- to 4-year-olds make accurate causal inferences on the basis of patterns of variation and covariation. Found that all three age groups considered information from various patterns of variation and covariation in judgments regarding two objects and activation of a machine. Three- and 4-year-olds used the…

Discusses how one Early Head Start program has benefited from collaborating with researchers. Notes that the program has clarified its theory of change, reflected on effective strategies, and trained staff on practices during home visits. Asserts that by using information about the quality of home visits, the program now provides better services…

Examined in 2 studies the ability of 2- and 3-year-olds to learn to use tools via imitation. Found that when shown a correct solution to a tool-using task, all children managed at least a partial solution. When shown an incorrect followed by a correct solution, 2-year-olds produced a partial solution and most 3-year-olds produced a full solution.…
