Children raised in chaotic households show affect dysregulation during later childhood. To understand why, we took day-long home recordings using microphones and autonomic monitors from 74 12-month-old infant-caregiver dyads (40% male, 60% white, data collected between 2018 and 2021). Caregivers in low-Confusion Hubbub And Order Scale (chaos)…

Emotions remain something of a mystery for most of us even when we accept their centrality to development in general and to infancy in particular. I make 2 arguments in this paper. One: that the most crucial thing about emotions is that they allow mutuality of engagement with other emotional beings--not only evoking responses, but also provoking…

Maternal singing is considered vital to infant well-being. This study focuses on vocal emotion expressions in infant-directed singing among mothers in war conditions. It examines the questions: (a) how traumatic war events and mental health problems are associated with the content and valence of vocal emotion expressions and (b) how these emotion…

Although there is growing consensus that parental stress is a risk factor in child development, longitudinal studies of its effects are few. This study tested a sample of 231 mother-child dyads in terms of whether the relations between the global experience of stress in mothers (perceived stress scale) and child temperamental characteristics…

The author examines the effect of blindness on a child's acquisition of reaching, grasping, and crawling skills which are said to be necessary for coping effectively with the environment. (GW)

Examined whether young infants produced differentially organized hand and arm actions in relation to affective expressions when the infants were presented with social and nonsocial stimuli. (PCB)

Examined mothers' and infants' affect in play and infant sex as predictors of infants' response to the still-face situation. (PCB)

Studies the communication of affect between depressed mothers and their infants and its relation to infant socioemotional and cognitive development through face-to-face interaction. Findings indicate that there are correspondences between the behavior of depressed mothers and their infants. (Author/BB)

Examines the course of emotion expression development during the first 2 years of 58 full-term and preterm children through videotapes of mother/infant pairs. Mothers' contingency behavior appeared to have an effect on emotional development, as did birth status and gender. Prematurity was associated with differential socioemotional development.…

Mothers whose infants varied in early biological characteristics (born at term, n = 120; born at very low birth weight [VLBW], n = 144) were randomized to a target group (n = 133) or developmental feedback comparison group (n = 131) to determine whether learning responsive behaviors would facilitate infant development. The target condition…

The Mutual Regulatory Model is used to describe the infants' dual task of regulating simultaneously his internal emotional state and his engagement with the external environment. (Author/BB)

Irritability levels and activity reactivity to aversive tactile stimuli were compared for 144 full-term neonates and 191 preterm infants. Irritability ratings increased across the five trials both during and post stimulation for full-term females and males and for preterm females, but not for preterm males. Activity ratings decreased across trials…

This study explored questions concerning the specificity of facial expression of emotions in infants. A sample of 27 infants (nine each at ages 10, 11, and 12 months) were tested in six experimental and six control conditions. Two of the experimental conditions were designed to elicit fear, two happiness, and two surprise. Videotapes of the…

The infant's impressions of his environment are viewed by several philosophers, including Jean Piaget. There has been some past tendency to suppose that, prior to the acquisition of language, the infant has no real impressions about his environment. More recent understandings consider that the infant is capable of conceptualization and can express…

Compared Duchenne and non-Duchenne smiles of 1- to 6-month olds during weekly videotapes of mother/infant interaction for clues regarding emotional significance. Correlated levels of Duchenne and non-Duchenne smiling within sessions; found that they had similar developmental trajectories. Duchenne smiles were typically preceded by non-Duchenne…
