This study addresses a gap in the attachment literature by investigating maternal neural response to cry related to infant attachment classifications and behaviors. Twenty-two primiparous mothers and their 18-month old infants completed the Strange Situation (SS) procedure to elicit attachment behaviors. During a separate functional MRI session, mothers were exposed to their own infant's cry so...

The purpose of this study was to examine the effects of multi-modal stimulation (differing amounts of light and vocal stimulation) on preterm infants’ behavioral and state organization. Specifically, we looked at the effects that supplemental vocal stimulation (taped female voice) had when varied in amount of exposure (three times a day versus once a day) and when provided in different lighting...

Because feed is the major cost to pork production, management practices and breeding strategies are aimed at optimizing feed intake. Knowledge about the shape of feed intake and feeding behavior curves may be of interest for optimization of lean meat production. This study investigated trends based on daily measurements of feeding behavior in 200 Duroc barrows, originating from 5 sires and 200 ...

This study investigated the development of attachment relationships in 38 foster infant-caregiver dyads over the first 2 months of placement. We used the Parent Attachment Diary to measure foster infants' daily attachment behaviors, the Adult Attachment Interview to examine foster parents' attachment states of mind, and Ainsworth's Strange Situation to capture attachment classifications. We exa...

Preterm infants residing in an NICU were randomly assigned to a massage therapy or to a control group. The preterm infants in the massage therapy group received three 15-min massages each day for 5 consecutive days, with the massages consisting of moderate pressure stroking to the head, shoulders, back, arms and legs and kinesthetic exercises consisting of flexion and extension of the limbs. In...

The end of the first year marks an important social-cognitive transition for human infants. Around this time, they start to engage in a new variety of joint attentional behaviors not clearly present in the preceding months. These new social behaviors are thought to index infants' understanding of intentions in others-an understanding that ultimately gives way to an active participation in human...

Oral and manual exploration are part of the foundation of problem solving and cognition in infancy. How these develop in an at-risk population, infants in poverty, is unknown. The current study tested exploratory behaviors longitudinally at 6, 9, and 12 months in infants from high- and low-socioeconomic (SES) families. Oral exploration consisted of passive and active mouthing and looks after ac...

OBJECTIVES To describe the main findings of studies of behavioral and neural correlates regarding the development of facial emotion processing during the first year of life in typically developing infants and infants of depressed and/or anxious mothers. SOURCES Comprehensive, non-systematic review of the literature on studies about individual differences in facial emotion processing by newbor...

The purpose of this study was to examine sleep patterns in a large sample of infants and toddlers (ages birth to 36 months) in Korea, and to compare sleep patterns, sleep problems, sleep ecology, and parental behaviors to global sleep data on young children in both predominantly Asian (P-A) and predominantly Caucasian (P-C) countries/regions. We additionally examined parent and child demographi...
