Retrospective studies indicate 2 major classes of autism spectrum disorder (ASD) onset: early and later, after a period of relatively healthy development. This prospective, longitudinal study examined social, language, and motor trajectories in 235 children with and without a sibling with autism, ages 6-36 months. Children were grouped as: ASD…

This study examined the increase in salivary cortisol from midmorning to midafternoon in 151 children (3.0-4.5 years) in full-time home-based day care. Compared to cortisol levels at home, increases were noted in the majority of children (63%) at day care, with 40% classified as a stress response. Observations at day care revealed that intrusive,…

A depth-of-processing incidental recall task for maternal-referent stimuli was utilized to assess basic memory processes and the affective valence of maternal representations among abused (N = 63), neglected (N = 33), and nonmaltreated (N = 128) school-aged children (ages 8-13.5 years old). Self-reported and observer-rated indices of internalizing…

Children between the ages of six and 11 were asked to recall personal experiences of pity, anger, and guilt and to rate the cause of each emotion on degree of controllability. Results were interpreted as evidence that guilt in young children may be a qualitatively different emotion because of its closer link to outcome than to perceived…

A group of 20 abusive mothers and a group of 20 matched, nonabusive mothers were shown slides depicting infants in seven different emotional states. Abusive mothers were more likely to incorrectly identify specific signals of emotion and to label negative affect as positive. (Author/RH)

Quantifies behavioral periodicities or cycles during face-to-face interaction between three- and five-month-old term and preterm infants and their mothers. Compares the temporal organization of social interaction between term and preterm infants. Spectral and cross-spectral techniques showed the existence of periodicities. Differences were found…

Examines the level and quality of object play and other cognitive and socioemotional aspects of the play situation, both as individual entities and as interrelated aspects of the way the child with Down syndrome approaches and deals with the animate and inanimate world. Relationships among these aspects and the child's level of functioning were…

Compares the responses of 14 child abusers and a matched group of nonabusers to videotapes of crying and smiling infants. Psychophysiological and subjective self-report measures were taken. (SS)

Recorded cognitive event-related potentials from maltreated and nonmaltreated children during presentations of happy, angry, or neutral facial expressions. Found that for nonmaltreated children, the average amplitude of P300 was comparable for responses to happy and neutral expressions. Maltreated children displayed larger P300 amplitude to…

Regardless of birthweight, ventilated infants received the lowest ratings for overall performance on the Infant Behavior Record. Ventilated newborns of very low birthweight were more likely to receive ratings characterizing an overly active infant with a short attention span, and never-ventilated infants of very low birthweight were most likely to…

Compares the expression of affect towards parents of 8- to 11-year-old children raised in one of three environments: kibbutz children raised communally with peers, kibbutz children raised in families, and city children raised in traditional families. (SS)

Observed 193 children at 4.5 years who had been classified at 4 months as high or low reactive to stimulation for signs of inhibited or uninhibited behavior. Children classified as high reactive were less spontaneous and less sociable than low-reactive children, but only a small proportion maintained a consistently inhibited or uninhibited…

Investigated effects of depressed mothers' touching on their infants' behavior during still-face situation. Subjects were 48 mothers and their 3-month-old infants. Findings suggested that by providing touch stimulation for their infants, depressed mothers can increase infants' positive affect and compensate for negative effects often resulting…

Evaluated respiratory sinus arrhythmia (RSA) and heart period in 5-month-olds during interaction challenges. Found that during object-mediated challenge, RSA increases were uniquely related to positive engagement. During person-mediated challenge, subjects showed more complex integration of autonomic and behavioral responses such that only infants…

Mothers' ability to decode their children's nonverbal expressions of four affects (happiness, sadness, fear, and anger) was contrasted with the decoding ability of a matched group of nonmothers. Results indicate that mothers were accurately able to decode expressions of happiness but had relative difficulty with decoding expressions of sadness,…
