The influence of culture on cognitive development is well established for school age and older children. But almost nothing is known about how different parenting and socialization practices in different cultures affect infants' and young children's earliest emerging cognitive and social-cognitive skills. In the current monograph, we report a…

We present a domain-general framework called "constrained attentional associative learning" to provide a developmental account for how and when infants form concepts for animates and inanimates that encapsulate not only their surface appearance but also their movement characteristics. Six simulations with the same general-purpose architecture…

Reviews studies on the effects of infant food supplementation on the children's later cognitive development. Suggests that the study by Pollitt et al. reported in this monograph presents evidence that correcting early malnutrition provides large benefits to children when they become adolescents and young adults. (BC)

Notes two faulty aspects of the Reznick et al., twin study (PS 526 688): the expressive language measure at 14 months, which has practically no spread of item difficulty, as well as measures included to assess specific cognitive characteristics; and the notion of infant transition as it affects interpretation of the results. (HTH)

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…

Reviews early theoretical and research literature on handedness and places it within the larger context of the nature-nurture controversy. Discussion focuses on Baldwin's study of the development of hand preference in infants in relation to the recapitulation theory, mental development ("dynamogenesis"), and speech development.…

Examines the meaning of reaction time (RT) and the possibility that it may predict other cognitive and motor skills in the first year of life. Considers two competing models that specify the information-processing components underlying RT performance. Describes the neural data needed to definitively choose between the models and considers…

Examined data from 408 pairs of identical, same-sex fraternal twins at 14, 20, and 24 months to assess cognitive development and to identify genetic and environmental influences on phenotypic similarity. Found various patterns of development for separate constructs, for females versus males on each construct, and for individuals across constructs.…

Used Visual Expectation Paradigm to describe information processing changes and individual differences during first year of life. Found regular age changes in mean reaction time and variability but not in minimum reaction time, suggesting that growth rate of sensory-detection information is constant during first year but age changes occur in level…

Speculates on underlying processes for the reaction time variance and age differences in anticipation latency using the Visual Expectation Paradigm. Discusses the dichotomization of reactive and anticipatory behavior, limitations of longitudinal designs, drawbacks in using standard procedures and materials, and inferences that can be made…

Suggests that children construe the world as they develop relationships with other individuals. Offers considerations regarding developmental changes marking the first year of life and argues that cognition is framed in public social exchanges and private dialogical thinking. (DLH)

Compared the performance of two groups of subjects on psychoeducational tests taken during adolescence and early adulthood. Adolescents who had received a protein supplement when they were infants scored higher on tests of knowledge, numeracy, reading, and vocabulary and showed faster reaction times in information-processing tasks than adolescents…

A comprehensive evaluation of the present state of infant and preschool mental testing in the United States is the concern of this monograph by the Society for Research in Child Development. Literature, technical and professional, covering the concept of intelligence and its measurement, was reviewed, organized, and summarized (chapters II and…

Studied partner and site novelty for mother-infant, stranger-infant, and mother-stranger face-to-face interactions. Found that adult-infant vocal timing measures at age 4 months did predict attachment and cognition at age 12 months. Comparison of mother-infant and stranger-infant interactions suggested the dynamics of infants' early…
