There is general consensus that the representation of the human face becomes functionally specialized within the first few months of an infant's life. The literature is divided, however, on the question whether the specialized representation of the remainder of the human body form follows a similarly rapid trajectory or emerges more slowly and in…

It has been suggested that due to functional similarity, sortal object individuation might be a primordial form of psychological essentialism. For example, the relative independence of identity judgment from perceived surface features is a characteristic of essentialist reasoning. Also, infants engaging in sortal object individuation pay more…

Engaging, focusing, and persisting in the completion of tasks are among the skills needed for school success. Tracking whether a child is learning cognitive problem-solving skills is essential in knowing if they are acquiring skills important for development and school readiness; and if not, how they are responding to early intervention. Use of…

Atypical motor development has frequently been reported in infants at elevated likelihood for autism spectrum disorder. However, no previous study has used detailed motion capture technology to compare infant siblings of children with autism spectrum disorder and infant siblings with no familial history of autism spectrum disorder. We investigated…

Substantial evidence endorses the early assessment of cognitive development to promote children's developmental health and well-being. Especially in the Brazilian context, there is a paucity of standardized screening and assessment tools with normative data to evaluate young children. This study provided initial reliability and validity evidence…

Efficient attention control is fundamental for infant cognitive development, but its early precursors are not well understood. This study investigated whether dyadic visual attention during parent-infant interactions at 5 months of age predicts the ability to control attention at 11 months of age (N = 55). Total duration of mutual gaze (MG) was…

The purpose of the study was to evaluate fine- and gross-motor development and basic cognitive skills in 3-18 month-olds in relation to home factors, age and weight. Three hundred and seventy mother-child dyads were recruited. For age, two groups were analyzed: 3-11 months and 12-18 months. Motor and basic cognitive skills were assessed using the…

Four experiments investigated infants' and adults' knowledge of the identity of objects in a causal sequence of events. In Experiments 1 and 2, 18- and 22-month-olds in the visual habituation procedure were shown a 3-step causal chain event in which the relation between an object's part (dynamic or static) and its causal role was either consistent…

Characterizing the nature of linguistic representations and how they emerge during early development is a central goal in the cognitive science of language. One area in which this development plays out is in the acquisition of dependencies--relationships between co-occurring elements in a word, phrase, or sentence. These dependencies often involve…

This study investigated relations among children's Theory-of-Mind (ToM) development, early sibling interactions, and parental discipline strategies during the transition to siblinghood. Using a sample of firstborn children and their parents (N = 208), we assessed children's ToM before the birth of a sibling and 12 months after the birth, and…

The meaning, mechanism, and function of imitation in early infancy have been actively discussed since Meltzoff and Moore's (1977) report of facial and manual imitation by human neonates. Oostenbroek et al. (2016) claim to challenge the existence of early imitation and to counter all interpretations so far offered. Such claims, if true, would have…

Sex is a significant social category, and adults derive information about it from both faces and bodies. Research indicates that young infants process sex category information in faces. However, no prior study has examined whether infants derive sex categories from bodies and match faces and bodies in terms of sex. In the current study,…

This article examines similarities and differences in Chilean teachers' competences, which were organized into profiles, and the associations of these profiles with children's language development. Teacher-child interactions were assessed when the children were 12 (n=99) and 30 months old (n=73), using the Adult Sensitivity Scale, the Evaluation…

This paper uses meta-analytic techniques to estimate the separate effects of the starting age, program duration, and persistence of impacts of early childhood education programs on children's cognitive and achievement outcomes. It concentrates on studies published before the wide scale penetration of state-pre-K programs. Specifically, data are…

Fragmented sleep is common in infancy. Although night awakening is known to decrease with age, in some infants night awakening is more persistent and continues into older ages. However, the influence of fragmented sleep on development is poorly known. In the present study, the longitudinal relationship between fragmented sleep and psychomotor…
