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…

The question of the acquisition of the first social phenomena by newborns is a crucial issue both in understanding the mental development and the ontogenesis of social interaction. The review attempts to investigate other researches that observe social behavior in studies with no communication between subjects. This current analysis reviews…

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…

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…

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…

Although previous research with adult humans and nonhumans has suggested a relationship between sleep behavior and brain serotonin levels, no studies have been made of the relationship of normal children's or infants' sleep patterns to serotonin levels, tryptophan metabolism, or diet. This study investigates the relationship between dietary…

To determine whether heart rate increase can be attributed to increased sucking amplitude for sweeter fluids, sucking and heart rate of 20 full-term infants were studied. (MP)

A replication study of directed reaching in children. In response to a visual stimulus the arm and hand movements of infants were videotaped and analyzed to determine whether the position of the ball affected the direction of the infants' extensions. (Author/SS)

Examines the relationship between an infant's sex and its capacity to maintain eye contact. Subjects were 15 male and 15 female newborn infants. (MP)

Examines the relation between aspects of the fundamental frequency (basic pitch) of 16 infant newborn cries and 28 multiparous mothers' perceptions of those cries. Results support the hypothesis that increases in fundamental frequency are related to increases in maternal perceptions of the intensity of the infant's cry. (Author/RWB)

Studied head-orientation response of breast-feeding neonates in paired-choice odor tests. Found that 2-day olds detected amniotic fluid and colostrum, treating them as similar sensorily and/or hedonically. Four-day olds exhibited a preference for breast milk. Three-day olds oriented longer toward the odor of their own amniotic fluid than alien…

In a longitudinal study of 29 middle-class Japanese infants, an attempt was made to identify early temperamental dispositions that predict later attachment classification. Specifically, Ainsworth Strange Situation observations at 12 months of age were preceded by, among others, observation of distress evident in newborns when a nipple was removed;…

This paper reviews a few studies, both in animals and humans, that are relevant in helping us to understand factors affecting infant-mother interaction. (MM)
