Niche construction is the modification of components of the environment through an organism's activities. Humans modify their environments mainly through ontogenetic and cultural processes, and it is this reliance on learning, plasticity and culture that lends human niche construction a special potency. In this paper we aim to facilitate…

The aim of the present study was to explore and compare systematically the developmental patterns of certain aspects of imitation, longitudinally from 2 to 10 months, in interactions of infants with grandfathers and grandmothers. Sixteen infants were video-recorded at home in the course of spontaneous dyadic interactions with maternal grandfathers…

There is evidence for developmental hierarchies in the type of information to which infants attend when reasoning about objects. Investigators have questioned the origin of these hierarchies and how infants come to identify new sources of information when reasoning about objects. The goal of the present experiments was to shed light on this debate…

Three experiments investigated 14-, 18-, and 24- month-old infants' understanding of visual perception. Infants viewed films in which a protagonist was either able to view the location of a hidden object (Visual Access condition) or was blindfolded when the object location was revealed (No Visual Access condition). When requested to find the…

Argues that in analyzing effects of early experience on development of cognitive competence, theoretical analyses as well as empirical investigations should be based on a transactional model of development. Shows optimal stimulation hypothesis, particularly the enhancement prediction, seems to represent a transactional approach to the study of…

Maintains that Madole and Oakes' hypotheses are incorrect. Shows that conceptual development frequently goes from the abstract to the concrete and that extensive literature shows that there is more than one kind of categorization. Discusses ways in which perceptual and conceptual categorization differ. (Author/KB)

Explores giftedness from infancy to adolescence within a psychodynamic developmental framework. Gifted development is discussed in terms of drive, ego functions, object relations, and self-experience. Also discussed are the history of giftedness, gifted infants and preschoolers, gifted school-age children, and giftedness in male and female…

Claims that Matthews sees independence as moving freely and being able to function apart from the adult, leading to competence and cognitive development for life. Reiterates the importance of emotion, relationships, and the mother as the central part of the child's prepared environment. (MOK)

Designed for use in in the home and in professional child-care settings, this program presents developmentally appropriate activities to support development of infants from 1 to 2 years of age. Each of the six 2-month long units contains 24 sets of activities call Activity Plans, with the suggestion to use three activity plans per week. Each unit…

Investigates whether temperamental differences mediated infants' responses to the early environment and explores the nature of the relationship between temperament and cognitive-intellectual development. Subjects, 100 six-month-old infants, were observed in their homes three times over a three-week period. Data suggest a greater reactivity to the…

Investigated genetic change and continuity within the domains of temperament, emotion, and cognition and language for 200 pairs of twins assessed at 14 and 20 months of age. Correlations of measures at the two ages indicated that individual differences in the second year of life showed greater change than continuity on most measures. (MDM)

Used path analysis in two experiments to examine possibility that age difference in infants' long-term retention were artifacts of correlated differences in learning rates or learning opportunities. Found that developmental declines in forgetting rates between 12 and 18 months were independent of developmental differences in learning. Age…

Responds to Mandler's critique of authors' view of infant categorization. Maintains that their view of infant categorization is not characterized by a shift from one type of category to another but by gradual changes in the kinds of information infants can use in forming categories. Clarifies position regarding a single categorical process using…

Designed for use in the home and in professional child-care settings, this program presents developmentally appropriate activities to support growth and development of infants from birth to 1 year. Each of the six 2-month long units contains 24 sets of activities called Activity Plans, with the suggestion to use three activity plans per week. Each…

Imitation by infants functions in two ways: (1) to help the individual understand a puzzling event, and (2) to indicate mutuality with another person. Although changes in cognitive understanding influence the course of imitation, the occurrence of imitation in specific situations may be governed by the interplay of the two functions that imitation…
