This paper aims to provide a systematic review of the literature on the associated factors with infant sleep-wake behaviour during the first 12 months of life, namely (1) the factors positively and negatively associated with sleep-wake behaviour and (2) the factors positively and negatively affected by sleep-wake behaviour. This systematic review…

Background: There is growing interest in research understanding the individual-specific predictors of child callous-unemotional (CU) traits, particularly in early childhood. Objective: This study reviewed evidence from studies that investigated the relationship between early child temperament factors (between 0 and 3 years) and CU traits in…

Joint attention (JA) is the purposeful coordination of an individual's focus of attention with that of another and begins to develop within the first year of life. Delayed, or atypically developing, JA is an early behavioural sign of many developmental disabilities and so assessing JA in infancy can improve our understanding of trajectories of…

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…

The aim of this review is to identify the behavioural soothing interventions (BSIs) used for reducing infant crying and to determine their effect. Studies had to describe an experimental study addressing infant crying and BSIs in the first six months after birth. Searches were performed in Web of Science, Pubmed, Science Direct, EBSCOhost,…

International research, while mostly conducted in high-income countries, repeatedly states that parents of premature infants have increased needs and require additional information and varied support channels after the infant's initial discharge from hospital. However, the perceived self-reported needs of parents concerned with the caregiving of…

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…

Wynn's (1992) seminal research reported that infants looked longer at stimuli representing "incorrect" versus "correct" solutions of basic addition and subtraction problems and concluded that infants have innate arithmetical abilities. Since then, infancy researchers have attempted to replicate this effect, yielding mixed…

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…

This paper offers a review of the literature on the role of imitation in the earliest stages of social interaction between babies and familiar partners. The review focuses on the ways in which reciprocal imitation marks familiar relationships that provide special contexts for babies to engage actively and exuberantly in the construction of a…

Research in the area of infant development has endless facets of investigation. No one facet of research is more important than another, and all of the findings work in a synchronous fashion to facilitate our understanding of child development. Research on child development has proliferated across the centuries. Infant characteristics like…

The underlying theme of this review is that fine motor assessment for skills acquired during the first year of life includes a description of the coordination of reach and grasp behaviors into functional understanding, purposeful retention of an object, and manipulatian. The developmental sequence of these responses is listed in various…

Argues that there are important individual differences in infant responses to frustrating situations. These different patterns of behavior have important implications for subsequent responses to challenge. Also argues that these different coping responses are in part temperamentally based and that individual differences in temperament help us to…

The development of intention to communicate among infants is discussed. In addition, the construct of intention is examined and a model describing the development of intention is proposed. The model is used to describe both the development of intentional behavior and communication as an intentional behavior. (Author/RH)

Reviews research that uses autonomic responses of human infants as dependent measures. Focuses on the history of research on the autonomic nervous system, measurement issues, and autonomic correlates of infant behavior and systems. (RJC)
