Children (2;10 to 4;7 years) taught passive sentences with forms employing animate patients could produce and comprehend passives better than children taught with forms employing inanimate patients. This indicates that "perspective" is the cognitive counterpart to the formal category of subject and that language acquisition is connected…

Introduces the time window, a construct that characterizes when and how the integration of knowledge occurs, which is fundamental to the development of cognition. Describes the characteristics of time windows, evidence supporting them, factors that affect them, research illustrating their generality, and theoretical and applied implications. (ET)

Two experiments examined children's semantic representations and semantic naming errors. Results suggested that functional and physical properties are core aspects of object representations in the semantic lexicon and that the degree of semantic knowledge makes words more or less vulnerable to retrieval failure. Discussion focuses on the dynamic…

This case study reports on the progress of Navon, a 13-year-old boy with prelingual deafness, over a 3-month period following exposure to Logo, a computer programming language that visualizes specific programming commands by means of a virtual drawing tool called the Turtle. Despite an almost complete lack of skills in spoken and sign language,…

The study examined the longitudinal association of parental involvement in Head Start parent-focused programs, parenting behaviors, and the cognitive development of children by specifying two longitudinal growth models. Model 1 examined the longitudinal effects of the parental involvement in three Head Start parenting programs (parenting classes,…

Most educators are familiar with Lev Vygotsky's concept of the "zone of proximal development," yet the bulk of Vygotsky's pioneering theory of cognitive development largely remains unknown. This volume provides a systematic, authoritative overview of Vygotsky's work and its implications for educational research and practice. Major topics include…

The emergence of shared symbol systems is considered to be a pivotal moment in human evolution and human development. These changes are normally explained by reference to changes in people's internal cognitive processes. We present 2 experiments which provide evidence that changes in the external, collaborative processes that people use to…

Research Findings: The purpose of this study was to investigate how neighborhoods and neighborhood socioeconomic disadvantage impact school readiness over time. School readiness was measured using the Early Development Instrument (EDI) for 3 populations of kindergartners in 2001, 2003, and 2005 in Saskatoon, Saskatchewan, Canada. EDI results…

This report presents findings from the Massachusetts Family Child Care study, a two-year evaluation designed to examine the impacts on providers and children of an early childhood education program aimed at improving the development and learning opportunities in the care settings and, as a consequence, the outcomes for children in care. The early…

The nature of predictive relations between early language and later cognitive function is a fundamental question in research on human cognition. In a longitudinal study assessing speed of language processing in infancy, Fernald, Perfors and Marchman (2006 ) found that reaction time at 25 months was strongly related to lexical and grammatical…

Two studies tested the observation that infants learn to use a "whole object assumption" between the ages of 8 and 15 months, meaning that they expect a word to apply to the whole object to which it refers. The first study investigated the possibility that infants of 8 to 10 months may attend differently, and more selectively, to events…

A discussion of dramatic play and its implementation. (CH)

A study to investigate the development of children's ability to relate concepts and thus understand metaphors by examining their performance on three concept-relating tasks is reported. Abstract-metaphoric, concrete-metaphoric, and literal taxonomic relationships were embedded in an analogy-like binary choice task. In this type of task, the…

Preschool children were tested for their understanding of the use of definite and indefinite articles in 2 kinds of story-telling tasks. (ST)

The study investigated whether training in object permanence and/or means-end followed by a language training program will result in the learning of more language (as measured by number of words and syntactic complexity) than the language training program alone with 32 profoundly retarded children (3 to 10 years old). Secondary goals included…
