Piaget's theory of space perception is presented in the format of a hypothetico-deductive system. Eleven hypotheses regarding infants' space perception are defined, and Piaget's evidence for each is summarized. Presuppositions underlying the arguments are explicated. Critical notes are inserted and general conclusions are briefly discussed.…

Calls for a process-oriented approach to study of categorization in infancy. Maintains that further understanding of infant categorization and its changes with development requires a more direct assessment of infants' category formation. Argues that two research directions will enhance understanding of categorization: (1) contextual variations on…

There have been few investigations of the effects of very immature preterm birth on specific linguistic competencies and phonological working memory at preschool age. Study 1 aimed to investigate early grammatical abilities in very immature healthy preterms, taking into account their cognitive development and biological and social factors. The…

Twelve- and 14-month-old infants' ability to represent another person's visual perspective (Level-1 visual perspective taking) was studied in a looking-time paradigm. Fourteen-month-olds looked longer at a person reaching for and grasping a new object when the old goal-object was visible than when it was invisible to the person (but visible to the…

Young infants tend to look longer at physical events that have unexpected outcomes than those that have expected outcomes, suggesting that they have knowledge of physical principles such as numerosity and occlusion (Baillargeon & Graber, 1987; Wynn, 1992). Although infants are typically tested in the presence of a caregiver, the social component…

Recent deferred imitation experiments are shedding new light onto the development of declarative memory during early infancy and revealing interesting new facets, for example, that infants process novel information on more than one level. In the current study with 13-month-old infants we examined relational information processing of novel,…

Do infants use past linguistic information to interpret an ambiguous request for an object? When infants in this research were shown 2 objects, and asked for 1 with an indefinite request (e.g., "Can you get it for me?"), both 15- and 18-month-olds used the speaker's previous reference to an absent object to interpret the request. The 18-month-olds…

This annual report discusses several topics related to the work of the Clinical Center for Child Development at Hokkaido University in Sapporo, Japan. The articles are: (1) "Other's Voice/Own Voice: (Re)production of Other's Voice and Its Apprenticeship in Japanese Young Children" (Shing-Jen Chen); (2) "Intersubjectivity during…

Reviews literature suggesting that a sociocultural model of infant social development is needed to examine variable influencing infants' interactions with caregivers. Significant variables include familial influences and cultural expectations. Positive development requires that these variables lead to adults who respond appropriately to infant…

This paper is based on a presentation given at National Council of Teachers of Mathematics (NCTM) in 2005 in Anaheim, California. It explicates the developmental stages of the child as posited by Piaget. The author then ties each of the stages to developmentally appropriate mathematics instruction. The implications in terms of not imposing…

Relations of maternal and child characteristics to child cortisol reactivity to and recovery from emotional arousal were examined prospectively at approximately 7 months of age (infancy) and then again at approximately 15 months of age (toddlerhood). The sample was diverse and population based (N = 1,292 mother-infant dyads) and included families…

Reviews recent product-oriented outcome studies from the perspective of whether VLBW (very low birthweight) infants born since 1975 (when intensive care methods became relatively stabilized in effectiveness) show behavioral problems, intellectual impairment, linguistic or social deficits. (RWB)

Compared cognitive functioning of infants--at 8 and 18 months--with varying levels of prenatal cocaine exposure. Found that, with risk and polydrug exposure controlled, exposure groups did not differ at 8 months on Bayley Scales or recovery to a novel stimulus. Infants with heavy exposure or high environmental risk declined in mental development…
