Describes evolutionary developmental psychology as the study of the genetic and ecological mechanisms that govern the development of social and cognitive competencies common to all human beings and the epigenetic (gene-environment interactions) processes that adapt these competencies to local conditions. Outlines basic assumptions and domains of…

Maintains that one future direction for cognitive development research involves a closer integration with knowledge about the developing brain. Presents a framework for analyzing and interpreting postnatal functional brain development. Discusses three contributing hypotheses, within which a variety of phenomena associated with the neural basis of…

This study used a well-normed task of face recognition with 102 young children with autism, pervasive developmental disorder (PDD) not otherwise specified, and non-PDD disorders (mental retardation and language disorders) matched for chronological age and either verbal or nonverbal mental age. Autistic subjects exhibited pronounced deficits in…

Presented neonates with lexical and grammatical words prepared from natural maternal speech. Found that neonates could categorically discriminate the sets based on a constellation of perceptual cues that distinguished them. Suggested that this ability to discriminate words on basis of multiple acoustic/phonological cues provides a perceptual base…

Three habituation experiments examined the necessary conditions under which infants invoked the principle of rational action, interpreting behavior as goal-directed action. Found that the rational action principle operated at 9 months but not at 6 months. Perceptual cues indicating agency were not necessary prerequisites for a goal-directed…

Examined whether preschoolers could recognize numerical equivalence for comparisons involving sequentially presented sets. Found that children recognized numerical equivalence for static sets earlier than for sequential sets. Memory of the number of sequentially presented objects emerged earlier than memory for the number of sequential events.…

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…

Notes how students learn to examine multiple elements of a text with critical perspective making analogies between others' writing and their own. Concludes that students may only have one opportunity to workshop their writing, but that intense learning experience, coupled with critical responses to another 20 or so drafts, coaxes writers into…

Explored in 2 studies 3- and 4-year-olds' understanding that the 5 senses can each lead to different types of knowledge. Found that 3-year-olds performed significantly poorer than 4-year-olds on all tasks, suggesting a marked transition in children's ability to recognize the origin of their modality-specific knowledge between 3 and 4 years.…

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…

Suggests that the findings of Legerstee, Barna, and DiAdamo (2000) are most parsimoniously explained by associative learning and may not constitute a precursor to later understanding of intentionality. Argues for the importance of differentiating between associative and inferential processes and reviews evidence that the understanding of…

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…

Explains the relationship between memory and learning and focuses on the psychological basis of learning, student motivation, and behavioral traits. Describes how learning experiences can be implemented in engineering education. (Contains 25 references.) (YDS)

Child's play may be at risk in today's technologically-oriented society. The limited interactive capacities of high-tech toys constrain the possibilities for cognitive development, interpersonal learning, and the quality of relationships that can be formed. Current high-tech toys change the nature of play, so that the object, rather than the…
