Developmental psychology focuses on how psychological constructs change with age. In cognitive development research, however, the specifics of this emergence is often underspecified. Researchers often provisionally assume linear growth by including chronological age as a predictor in regression models. In this work, we aim to evaluate this…

Purpose: Developmental functional modules (DFMs) are biological modules that are defined by their structural (morphological), functional, or developmental elements, and, in some cases, all three of these. This review article considers the hypothesis that vocal development in the first year of life can be understood in large part with respect to…

Infants start learning words, the building blocks of language, at least by 6 months. To do so, they must be able to extract the phonological form of words from running speech. A rich literature has investigated this process, termed word segmentation. We addressed the fundamental question of how infants of different ages segment words from their…

In this article, the author synthesizes research from several disciplines to shed light on play's central role in healthy development. Gordon builds on research in attachment theory that correlates secure attachment in infancy with adult well-being to demonstrate how playfulness might be a lifelong outcome of secure attachment and a primary…

Evaluates the degree to which the social-referencing perspective provides a valid explanation of some features of infant behavior. (MP)

The second of a four-part series on the development of infants and toddlers, this article reviews current research on social and emotional development during the first two years and provides a selected list of activities designed to promote infants' optimal development. Attachment behavior and affective behavior are two major topics explored. (EV)

Reviews the construct of attachment, its role as a motivational system in infancy, and its development in the first three years. Emphasizes that attachment must be assessed in the context of particular infant-parent relationships, and reviews specific infant and caregiver behaviors salient to the assessment of attachment.

Explores current theories of emotional development in order to identify the assumptions that could explain the strong antagonism toward early nonbasic emotions. Draws on the contrasting and polarity of viewpoints to examine the logical implications of these viewpoints for the very possibility of early nonbasic emotions and their reciprocal…

Observation indicates that affect is experienced prior to organized thought. After five months emotional responses are increasingly differentiated and independent of physical state. All childhood learning is propelled by affect. Adults who work with children must recognize their emotions to facilitate their acquisition of skills and knowledge.…

Parent/infant bonding is discussed in this study review. Bonding is defined prior to a discussion of research that places the concept in historical perspective. The discussion of research since 1950 focuses on Bowlby, Klaus and Kennell, Helfer, Mahler and Rheingold, and Brazelton. Attention is given to the capacities of the newborn, child abuse,…

Suggests that play begins with infant-adult interaction soon after birth rather than with much later peer interactions. Proposes a developmental sequence of infant play that reverses the sequences of the Howes peer play scale, and cites pertinent literature to support that proposal. (BC)

A newborn child can identify impressions by means of the sense organs with the help of "non-visible" sensory impressions such as tactile and kinesthetic. A communication arises early between different modalities and muscle activities, which make possible an early synchronization, and identity between the infant and its surroundings.…

Reviews research on, and offers definitions for, play and learning in infancy. Discusses the developmental sequence in early exploratory play and learning, individual differences in exploratory play, and the relationship between rearing environments and quality of exploratory play. Discusses implications for planning and implementing infant care…

The infant's impressions of his environment are viewed by several philosophers, including Jean Piaget. There has been some past tendency to suppose that, prior to the acquisition of language, the infant has no real impressions about his environment. More recent understandings consider that the infant is capable of conceptualization and can express…

This article suggests that disruption of social gaze interaction in the first months of life may be responsible for the core social, communicative, and imaginative/cognitive deficits of autism. Eye contact and face processing in individuals with autism, implications of a missed critical period for face processing, and implications for intervention…
