Investigates how the noun and verb classes develop in the free speech of a French child between the ages of 1 year, 2 months to 2 years and 6 months from the perspective of semantic and grammatical development. Analyses indicate that in French acquisition, nouns clearly predominate over verbs until 20 months of age at least, but that verbs are…

Explored the contexts in which preschool children use private speech or self-talk in the naturalistic setting of the preschool classroom, and age-related changes in the contexts in which preschoolers talk to themselves. (Author/VWL)

Discusses the potential of emerging communication and information technologies in terms of human development. Topics include distinctions between training and education, instrumental and developmental purposes, and differentiation and integration; developmental stages theory; a leadership seminar based on developmental stages; and uses of…

Prior research demonstrates that understanding theory of mind (ToM) is seriously and similarly delayed in late-signing deaf children and children with autism. Are these children simply delayed in timing relative to typical children, or do they demonstrate different patterns of development? The current research addressed this question by testing…

A review of the relevant literature about teaching group work and meeting core training standards is provided. The authors suggest a process by…

This review begins with a brief history from Piagetian perspective-taking development, through metacognitive development, and into the past and present field of theory-of-mind development. This field has included research on what infants and children know about a variety of mental states, on possible causes and consequences of mentalistic…

References to developmental stages and continua seem to be part and parcel of investigations into the acquisition of new grammars. Nonetheless, there seems to be an equivocation in the literature about which is actually the most helpful way of explaining how learner grammars evolve through time. Some see development essentially as gradual growth…

This study examined the efficacy of using hands-on sets of materials to teach two high school students with mental retardation the four situations for subtraction. This is a mixed methods study using a simple…

More than 40% of college drinkers are classified as high risk, and of these about 20% will continue this behavior into adulthood. This exploratory study compared the characteristics of high risk college drinkers who matured out with those who remained adult persistent. Respondents (4,428 alumni) completed a survey about college and current…
