Latency to soothe by a pacifier in the neonatal period was assessed for 107 full-term infants. When the infants were 9 and 12 months old, their mothers rated their temperament on standardized questionnaires. Correlations were computed between the neonatal latencies to soothe and the temperament ratings. When compared with neonates who soothed more quickly,(More)
The predictive relationship between neonatal behavior and temperament at 6 months was assessed in 62 pairs of twins. The neonatal assessment evaluated irritability, resistance to soothing, reactivity, and activity level across various activities. Temperament at 6 months was appraised by a laboratory assessment, ratings on the Infant Behavior Record, and a(More)

Neonatal sleep behaviors and behavioral state cycling were observed for 20 pairs of same-sex, fullterm twins in which one twin of the pair was appropriate-for-gestational-age (AGA) and the other twin was small-for-gestational-age (SGA). Time-sampling recordings were made in active sleep of number and vigor of limb movements, body and head movements, and(More)

Sex differences in neonatal temperament were examined in 30 pairs of full-term, opposite-sex twins. Behavior was assessed during feeding, during sleep, while awake for orienting responses, in response to a stressor, and for measures of spontaneous irritability and soothability. Composite and summary scales described irritability, resistance to soothing,(More)
Monozygotic (MZ) twins with a known chorion type were assessed in the neonatal period to determine if placentation was related to twin similarity in early temperament development. The sample included 48 pairs with monochorionic placentas and 29 pairs with dichorionic placentas. The assessment focused on irritability, resistance to soothing, activity while(More)
Cardiac and behavioral responses to a tactual stimulus were evaluated during the first sleep cycle for 3 groups of infants: 30 full terms, 30 nonintervened preterms, and 30 intervened preterms. Prior to testing, the latter group had received a regimen of multimodal sensory stimulation, which emphasized the tactual and vestibular modalities. The results(More)

Temperament differences between cotwins at least 15% discordant for birth-weight were compared for a group of 66 preterm twin pairs and a group of 70 fullterm twin pairs, assessed in the neonatal period. The assessment focused on irritability, resistance to soothing, activity, reactivity, and reinforcement value. For the most part, significant differences(More)

A pair of preterm, opposite-sex twins were examined during the lying-in period for behavioral and morphological effects of maternal alcohol and pentazocine abuse during pregnancy. A few morphological features typical of fetal alcohol syndrome were observed in each infant, and the male infant only was above the standardized mean in minor physical anomalies.(More)

Temperament stability over successive ages in the first 2 years of life was evaluated for 109 full-term and 81 preterm infants who were assessed at 6, 9, 12, 18, and 24 months. At each age, the infant was engaged in a series of age-appropriate vignettes in the laboratory, using a structured sequence of activities. Ratings were made of emotional tone,(More)
