This study was a prospective, randomized controlled trial. The study sample consisted of 105 healthy neonates who conformed to the case selection criteria. Neonates were randomly assigned to the following groups: swaddling (S), maternal holding (MH), and controls (C). The study data were obtained using an information form and the Neonatal Infant…

Kangaroo care (KC) or kangaroo mother care (KMC), sometimes called skin-to-skin contact, is a technique of newborn care where babies are kept chest-to-chest and skin-to-skin with a parent. The research was carried out experimentally to investigate the effect of the early kangaroo care by using Neonatal Comfort Behavior Scale in invasive…

What are the origins of object permanence? Despite widespread interest in this question, methodological barriers have prevented detailed analysis of how experience shapes the development of object permanence in newborn organisms. Here, we introduce an automated controlled-rearing method for studying the emergence of object permanence in strictly…

The behavior of newborns is ambiguous. Cultural models--representations shared by members of a community--provide new parents and others with a cognitive and motivational structure to understand them. This study asks members of several cultural groups (total n = 100) to judge the "similarity" of behavioral items in the Neonatal…

Self-propelled motion is a powerful cue that conveys information that an object is animate. In this case, animate refers to an entity's capacity to initiate motion without an applied external force. Sensitivity to this motion cue is present in infants that are a few months old, but whether this sensitivity is experience-dependent or is already…

Although a large body of evidence has accumulated on the young human infant's ability to imitate, the phenomenon has failed to gain unanimous acceptance. Imitation of tongue protrusion, the most tested gesture to date, was examined in a sample of 115 newborns in the first 5 days of life in 3 seating positions. An ethologically based…

In human newborns, spontaneous visual preference for biological motion is reported to occur at birth, but the factors underpinning this preference are still in debate. Using a standard visual preferential looking paradigm, 4 experiments were carried out in 3-day-old human newborns to assess the influence of translational displacement on perception…

Objective: To assess impact of tactile stimulation on neurobehavioral development of premature infants in Assiut City. Design: Quasi-experimental research design. Setting: The study was conducted in the Neonatal Intensive Care Unit at Assiut University Children Hospital, Assiut General Hospital, Health Insurance Hospital (ElMabarah Hospital) and…

Newborn infants preferentially orient to familiar over unfamiliar speech sounds. They are also better at remembering unfamiliar speech sounds for short periods of time if learning and retention occur after a feed than before. It is unknown whether short-term memory for speech is enhanced when the sound is familiar (versus unfamiliar) and, if so,…

Limited literature exists which examines how parents of infants hospitalized in the Neonatal Intensive Care Unit (NICU) transition from their infant's NICU hospital stay to home. This study examines the question, "What are the experiences of parents during their infant's transition from the NICU to home?" Grounded theory methods served as the…

Objectives: Infant crying is particularly frustrating to caregivers in the first few months of life and the most common trigger for shaking and abuse. The effectiveness of the "Period of PURPLE Crying" prevention materials (DVD and booklet) designed to increase knowledge and change behaviors related to crying and the dangers of shaking…

No evidence had been provided so far of newborns' capacity to give a matching response to 2D stimuli. We report evidence from 18 newborns who were presented with three types of stimuli on a 2D screen. The stimuli were video-recorded displays of tongue protrusion shown by: (a) a human face, (b) a human tongue from a disembodied mouth, and (c) an…

This longitudinal investigation of 84 infants examined whether the effect of 12-month attachment on 18- and 24-month exploration and sociability with unfamiliar adults varied as a function of newborn irritability. As expected, results revealed an interaction between attachment (secure vs. insecure) and irritability (highly irritable vs. moderately…

Five experiments examined 79 newborns' ability to discriminate and categorize a spatial relation, defined by the left-right spatial position of a blinking object-target with respect to a vertical landmark-bar. Three-day-old infants discriminated the up versus low position of an object located on the same side of the landmark-bar (Experiment 1) and…

Past research has shown that top-heaviness is a perceptual property that plays a crucial role in triggering newborns' preference toward faces. The present study examined the contribution of a second configural property, "congruency," to newborns' face preference. Experiments 1 and 2 demonstrated that when embedded in nonfacelike stimuli,…
