BACKGROUND Whether development of autism impacts the interactive process between an infant and his/her parents remains an unexplored issue. METHODOLOGY AND PRINCIPAL FINDINGS Using computational analysis taking into account synchronic behaviors and emotional prosody (parentese), we assessed the course of infants' responses to parents' type of speech in home movies from typically developing (T...

The early postpartum period lays important groundwork for later self-regulation as infants' dispositional traits interact with caregivers' co-regulatory behaviors to produce the earliest forms of self-regulation. Although emerging literature suggests that fetal exposure to maternal stress may be integral in determining child self-regulatory capacity, the complex pathways that characterize these...

Background: The newborn’s first bath, performed in Neonatal Intensive Care Units (NICU), is believed to be a stressful situation, especially for the premature infants. As a developmental care approach, swaddle bathing is a low-stress bathing method for vulnerable preterm neonates. Given the limited number of the studies examining this bathing method, the present study was conducted with the aim...

We examined continuity, stability, and change in behaviors reflecting infant reactivity and regulation. Healthy infants were observed in laboratory situations designed to elicit frustration when they were 5 (N = 87) and 10 months of age (N = 82). Behaviors indicative of reactivity included objective ratings of average intensity cry, peak intensity cry, and latency to cry. In addition, durations...

terms of an underlying causal or dispositional trait. Some infants are said to be strongly attached to an adult; others to be less strongly or not at all attached (e.g., Feldman & Ingham 1975) . Attachment is often operationalized in terms of a small number of "attachment behaviors." These include behaviors which promote proximity to presumed attachment figures and behaviors which are perhaps d...

BACKGROUND Neonatal brain injuries are the main cause of visual deficit produced by damage to posterior visual pathways. While there are several studies of visual function in low-risk preterm infants or older children with brain injuries, research in children of early age is lacking. AIM To assess several aspects of visual function in preterm infants with brain injuries and to compare them wi...

Infants actively explore their world in order to determine the different ways in which they can interact with various objects. Although research on infant perception has focused on how infants understand the differences between 2- and 3-dimensional objects, today's infants increasingly encounter 2D images with interactive qualities on smart-phone screens, tablets, and laptops. The purpose of th...

BACKGROUND Sleep disturbance has been reported in both pre-school and older children with atopic dermatitis (AD). There have been no studies examining whether sleep disturbance occurs at the onset of the AD, or develops later. OBJECTIVE To evaluate sleep characteristics in infants with AD. METHODS A cross-sectional survey based on interviews with parents of infants aged 1 year. AD was diagn...

What makes people help each other? To explore the origin of human altruism, we tested whether 16-month-old infants have an expectation of helping behavior when they observe an interaction between others. Infants watched videos in which one (capable) agent had achieved a goal while the other (incapable) one could not. In a subsequent situation, the capable agent either helped the incapable agent...

To understand the development of infant comprehension of visual obstructions and perspective-taking, this study tested the ability of N = 28 infants at 14, 16, and 18 months to adapt attention-sharing to visual constraints. An experimental task investigated how infants modify gaze following behaviors when an adult’s line of sight is obstructed by a barrier. From 14 to 18 months, infants gradual...
