Describes as advances of the Hauser-Cram et al. study increasing basic information about children with disabilities and their families, showing a combined organismic-contextual developmental perspective, and operationalizing tenets of developmental psychopathology. Considers as limitations: the role of etiology, the need to reconceptualize…

Examined 2-year-olds' language acquisition with an emphasis on the agency and intentionality of the child. Concluded that development depends on the child's expression of intentionality by actions (performance), the essential tension between the child's engagement and effort, and the integration of linguistic, cognitive, and social aspects of the…

Finds Bloom and Tinker's description and measurement of active, integrated, and situated children to be a credible scientifically rigorous paradigm for language acquisition research. Highlights their use of the naturalistic, observational method to understand the changing patterns of integration and use of multifaceted abilities in child language…

This document consists of the three 1999 issues of a newsletter disseminating information on the Society for Research in Child Development and providing a forum for important news, research, and information concerning advancements in child growth and development research. Each issue of the newsletter includes announcements and notices of…

Discusses questions answered and raised by the Cooper et al. study. Summarizes study's methodological contributions and emphasizes the more important lessons that meta-analysts may take from the study. Situates the study within literatures on summer learning and on education for poor/minority children. Discusses the potential for summer school to…

Analyzed 1.5- and 2.5-year-olds' problem solving and learning. Found that changes in toddlers' strategies could be assessed reliably on a trial-by-trial basis, that changes followed the basic form predicted by the overlapping waves model, and that analyses could reveal information about the qualitative and quantitative aspects of their learning.…

Discusses the importance of modeling, hints, and other information contexts for providing a link to establishing new problem-solving strategies for toddlers and older children. Discusses the use of the microgenetic approach for yielding valuable information about strategic development despite the lack of availability of verbal reports. Suggests…

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…

Examined recall by 14- to 32-month-olds for multistep event sequences experienced at 13 to 20 months. Found that within step-length groups, there were no age differences in the length of time over which memory was evidenced. With prompts by event-related props, age-related differences in memory appeared. Age-related effects were particularly…

Considers the relative lack of research attention to retention in developmental psychology and recent findings on age differences in retention. Highlights unresolved issues and how Bauer and colleagues' work may help set the research agenda and contribute to a shift in how early childhood retention is studied. Discusses memory strength,…

Used meta-analytic and narrative procedures to integrate results of 93 evaluations of summer school. Found that summer programs focusing on remedial or accelerated learning or other goals impacted positively on participants' knowledge and skills. Middle class students showed larger positive effects than disadvantaged students. Remedial programs…

This document consists of the three 1998 issues of a newsletter disseminating information on the Society for Research in Child Development and providing a forum for important news, research, and information concerning advancements in child growth and development research. Each issue of the newsletter provides announcements and notices of…

Assessed continuity and change in diagnosis, intelligence, and language skills in children with autism, Down Syndrome, and other developmental delays, identifying precursors of gains in language skills and peer engagement in mid-school years. Found that early nonverbal communication and play skills predicted initiations of peer play for Down…

Discusses methodological problems of Sigman and Ruskin's longitudinal study. Questions whether determination of specificity, universality, and uniqueness is appropriately addressed by between-syndrome comparisons. Describes problems with group matching, offers a method of partially correcting them, and argues that group designs have limited…
