Contributions of infant vagal regulation at 1 month to subsequent joint attention abilities
Abstract
Since birth, humans develop an ability to regulate their inner states and behaviors, when facing demanding situations, in order to restore calmness and engage with other persons and the surrounding environment. The present study analyzed whether 1‐month infant vagal regulation to auditory stimuli was associated with later joint attention abilities—responding to and initiating joint attention—in interaction with their mothers. Twenty‐three infants were assessed and measures of respiratory sinus arrhythmia—RSA (baseline and vagal tone change during auditory stimulation) were used as index of vagal regulati...

Salivary uric acid and C ‐reactive protein associations with hypertension in Midwestern Latino preadolescents and their parents
This study examined the associations between salivary uric (sUA) acid, salivary C‐reactive protein (sCRP), and hypertension among 151 participants (57 children, 57 mothers, 37 fathers) from 57 Midwestern Latino families. Participants self‐administered the salivary samples, and blood pressure was measured by researchers. Results showed sUA was associated across family members, and child hypertension was related to parents′ hypertension. sCRP was only related to sUA in fathers. Findings highlight the family‐level health connections, along with the importance for further investigations using salivary biomarkers with L...

Trajectories of resting frontal brain activity and psychopathology in female adolescents exposed to child maltreatment
Abstract
Resting frontal electroencephalogram (EEG) alpha asymmetry patterns reflecting different affective and motivational tendencies have been proposed as a putative mechanism underlying resilience among maltreated youth. This 2‐year prospective study examined whether developmental stability of resting frontal alpha asymmetry moderated the relation between child maltreatment severity and psychopathology in female adolescents (n = 43; ages 12–16) recruited from child protection agencies. Results identified two trajectories of resting frontal asymmetry: 60.5% displayed stable right and 39.5% displayed stable left ...

Correlation between maternal anxiety, reactivity of fetal cerebral circulation to auditory stimulation, and birth outcome in normotensive and gestational hypertensive women
This study investigated the correlation between maternal anxiety and blood flow changes through the fetal middle cerebral artery (MCA) after defined acoustic stimulation in 43 normotensive (C) and 40 gestational hypertensive (GH) subjects. Neonatal outcomes (gestational age at birth, Apgar score, birth weight) in the C and GH groups were analyzed. State (STAI‐S) and trait (STAI‐T) anxiety was assessed using Spielberger's questionnaire. The MCA blood flow was assessed once between 28 and 41 weeks of gestation using color Doppler ultrasound before and after application of defined acoustic stimulus. Relative size of the P...

Developmental social isolation affects adult behavior, social interaction, and dopamine metabolite levels in zebrafish
Abstract
The zebrafish is a social vertebrate and an excellent translational model for a variety of human disorders. Abnormal social behavior is a hallmark of several human brain disorders. Social behavioral problems can arise as a result of adverse early social environment. Little is known about the effects of early social isolation in adult zebrafish. We compared zebrafish that were isolated for either short (7 days) or long duration (180 days) to socially housed zebrafish, testing their behavior across ontogenesis (ages 10, 30, 60, 90, 120, 180 days), and shoal cohesion and whole‐brain monoamines and their metabolites...

All bonds are not alike: A psychoendocrine evaluation of infant attachment
Abstract
Characteristics of attachment were assessed in peer‐ and object‐reared lambs, and compared to mothered subjects by taking into consideration distress, proximity seeking, and exploration during two separation‐reunion tests in both the familiar and a novel environment. Plasma cortisol and oxytocin were assayed as physiological indicators of stress and being comforted during the separation‐reunion test. Rewarding properties of the familiar figures were also determined in a conditioned place preference‐like paradigm. Between‐group analysis revealed the existence of secure attachment with the mother, altera...

Prematurity and perinatal adversity effects hypothalamic ‐pituitary‐adrenal axis reactivity to social evaluative threat in adulthood
This study examined the long‐term effects of prematurity and perinatal adversity on individual differences in stress‐related reactivity and regulation of the HPA axis. A prospective sample of 155 infants born preterm and healthy (n = 20), medical illness (n = 48), neurological illness (n = 26), and small for gestational age (n = 24) and full‐term (n = 37) were recruited between 1985 and 1989. At age 23 years, multiple saliva samples were collected before and after participation in the Trier Social Stress Test and later assayed for cortisol. Results reveal that at age 23 years, infants born prematu...

Rapid facial reactions in response to happy and angry expressions in 7 ‐month‐old infants
Abstract
Humans rapidly and spontaneously activate muscles in the face when viewing emotional facial expressions in others. These rapid facial reactions (RFRs) are thought to reflect low‐level, bottom‐up processes, and are theorized to assist an observer to experience and share the affect of another individual. It has been assumed that RFRs are present from birth; however to date, no study has investigated this response in children younger than 3 years of age. In the present study, we used facial electromyography (EMG) to measure corrugator supercilii (brow) and zygomaticus major (cheek) muscle activity in 7‐month‐...

The influence of grasping habits and object orientation on motor planning in children and adults
Abstract
We investigated the influence of habitual grasp strategies and object orientation on motor planning in 3‐year‐olds and 4‐ to 5‐year‐old children and adults. Participants were required to rotate different vertically oriented objects around 180°. Usually, adults perform this task by grasping objects with an awkward grip (thumb and index finger pointing downward) at the beginning of the movement, in order to finish it with a comfortable hand position. This pattern corresponds to the well‐known end‐state comfort effect (ESC) in grasp planning. The presented objects were associated with different habitua...

Vigilance for threat accounts for inter ‐individual variation in physiological responses to adversity in rhesus macaques: A cognition × environment approach
Abstract
Early life adversity (ELA) can lead to poor health later in life. However, there is significant variation in outcomes, with some individuals displaying resilience even in the face of adversity. Using longitudinal data collected from free‐ranging rhesus macaques between birth and 3 years, we examined whether individual variation in vigilance for threat, an early emerging attentional bias, can account for variation in long‐term outcomes between individuals reared in similar environments. We found that ELA and vigilance during infancy interact to predict physiological dysregulation in Sympathetic Nervous System (...

Sensitivity to facial expressions among extremely low birth weight survivors in their 30s
The current study investigated the impact of birth weight on the ability to recognize facial expressions in adulthood among the longest known prospectively followed cohort of extremely low birth weight survivors (ELBW; <1,000 g). We measured perceptual threshold to detect subtle facial expressions and confusion among different emotion categories in order to disentangle visual perceptual ability from emotional processing. ELBW adults (N = 64, Mage = 31.9 years) were more likely than normal birth weight (NBW) controls (N = 82, Mage = 32.5 years) to see fear in angry faces. This finding was not a result o...

Behavioral flexibility in learning to sit
Abstract
What do infants learn when they learn to sit upright? We tested behavioral flexibility in learning to sit—the ability to adapt posture to changes in the environment—in 6‐ to 9‐month‐old infants sitting on forward and backward slopes. Infants began with slant at 0°; then slant increased in 2° increments until infants lost balance. Infants kept balance on impressively steep slopes, especially in the forward direction, despite the unexpected movements of the apparatus. Between slant adjustments while the slope was stationary, infants adapted posture to the direction and degree of slant by leaning backward...
