The lack of consensus on how to characterize humans' capacity for belief reasoning has been brought into sharp focus by recent research. Children fail critical tests of belief reasoning before 3 to 4 years of age (H. Wellman, D. Cross, & J. Watson, 2001; H. Wimmer & J. Perner, 1983), yet infants apparently pass false-belief tasks at 13 or 15…

Research examining the development of social cognition has largely been divided into two areas: infant perception of intentional agents, and preschoolers' understanding of others' mental states and beliefs (theory of mind). Many researchers have suggested that there is continuity in social cognitive development such that the abilities observed in…

The authors use the ECLS-B, a nationally-representative study of children born in 2001 to report the child care arrangements and quality characteristics for 2-year olds in the United States and to estimate the effects of differing levels of child care quality on two-year old children's cognitive development. Their goal is to test whether high…

Children who begin kindergarten with stronger skills learn faster than do those who enter with lower skills. Minority children tend to enter kindergarten already at a disadvantage, and the gap widens across time. However, little is known about cognitive development among American Indian young children. In this study, 110 American Indian infants…

This study examined parents' and toddlers' talk and viewing behaviour while co-viewing an educational infant DVD focused on teaching language. Sixty-four 12- to 25-month-old infants viewed a DVD in a laboratory with their parents. A cluster analysis on parent talk revealed three groups: High, Moderate, and Low Teaching Focus parents. The High…

Background: This study examined the association between prenatal cocaine exposure (PCE) and autonomic regulation at 13 months of age. Methods: Measures of respiratory sinus arrhythmia (RSA) were obtained from 156 (79 exposed, and 77 nonexposed) infants during baseline and during tasks designed to elicit positive (PA) and negative affect (NA).…

Like adults, infants use working memory to represent occluded objects and can update these memory representations to reflect changes to a scene that unfold over time. Here we tested the limits of infants' ability to update object representations in working memory. Eleven-month-old infants participated in a modified foraging task in which they saw…

Human infants' tendency to attribute goals to observed actions may help us to understand where people's obsession with goals originates from. While one-year-old infants liberally interpret the behaviour of many kinds of agents as goal-directed, a recent report [Kamewari, K., Kato, M., Kanda, T., Ishiguro, H., & Hiraki, K. (2005).…

For many decades, tool use has been viewed primarily as a cognitive achievement, an ability that separates not only adults and older children from infants, but humans from virtually all other species. According to this standard account, tool use and associated means-ends behaviors are dependent on symbolic or representational thinking. Organisms…

This commentary on J. Kagan (2008) addresses 2 issues. The first concerns the importance of studying developmental sequences and processes of change. The second concerns epistemological differences between contemporary neonativist approaches and classical theories of development. The commentary argues that classical theories of infant cognition…

Aim: The aim of this study was to determine neuropsychological performance (possibly predictive of academic difficulties) and its relationship with cognitive development and maternal education in healthy preterm children of preschool age and age-matched comparison children born at term. Method : A total of 35 infants who were born at less than 33…

Background: Postnatal depression (PND) is associated with poor cognitive functioning in infancy and the early school years; long-term effects on academic outcome are not known. Method: Children of postnatally depressed (N = 50) and non-depressed mothers (N = 39), studied from infancy, were followed up at 16 years. We examined the effects on…

The aims of this study were to investigate whether specific linguistic difficulties in preterm children persist at eight years and to examine the interrelationships between language and literacy in this population, compared with a control group of full-term children. Sixty-eight monolingual Italian preterms and 26 chronologically matched controls…

The authors review a viewpoint on human functional brain development, interactive specialization (IS), and its application to the emerging network of cortical regions referred to as the "social brain." They advance the IS view in 2 new ways. First, they extend IS into a domain to which it has not previously been applied--the emergence of social…

Infant sleep is a major source of concern for many parents. The aims of this longitudinal study were to assess: (a) the development of sleep patterns among infants, (b) the development of maternal cognitions regarding infant sleep, and (c) the relations between these domains during the 1st year of life. Eighty-five mothers were recruited during…
