Tactile/kinesthetic stimulation effects on preterm neonates.
Tactile/kinesthetic stimulation was given to 20 preterm neonates (mean gestational age, 31 weeks; mean birth weight, 1,280 g; mean time in neonatal intensive care unit, 20 days) during transitional ("grower") nursery care, and their growth, sleep-wake behavior, and Brazelton scale performance was compared with a group of 20 control neonates. The tactile/kinesthetic stimulation consisted of body stroking and passive movements of the limbs for three, 15-minute periods per day for a 10 days. The stimulated neonates averaged a 47% greater weight gain per day (mean 25 g v 17 g), were more active and alert during sleep/wake behavior observations, and showed more mature habituation, orientation, motor, and range of state behavior on the Brazelton scale than control infants. Finally, their hospital stay was 6 days shorter, yielding a cost savings of approximately $3,000 per infant. These data suggest that tactile/kinesthetic stimulation may be a cost effective way of facilitating growth and behavioral organization even in very small preterm neonates.

Type A behavior in preschool children.
Type A behaviors were observed in a group of 48 preschool children in different free-play and competitive situations. Interrater reliability was assessed on the Matthews Youth Test for Health (MYTH), and the children's and their parents' type A scores were compared. Scores on the MYTH were used to classify children as either type A or type B. Comparisons were made between type A and type B children's play in classroom and in laboratory situations. For the laboratory situations, 24 same-sex type A-type B dyads were formed, and the dyads were observed in free play, followed by car racing, by a tower-building contest, and by an interview. Type A children more frequently showed annoyed facial expressions, gross motor activity, interruptions during classroom free play, and gross motor activity and aggressive play with an inflatable Bobo doll during the laboratory free-play situation. Type A children more often won the car race and the tower-building contest, and they answered a greater number of questions and more frequently answered first during the interviews. These data are consistent with other findings on type A behavior in preschool children and suggest that the behavioral dimensions of type A (competitiveness and impatience-aggression) may emerge as early as the preschool years, particularly in competitive situations.

Discrimination and imitation of facial expression by neonates.
Human neonates (average age, 36 hours) discriminated three facial expressions (happy, sad, and surprised) posed by a live model as evidenced by diminished visual fixation on each face over trials and renewed fixations to the presentation of a different face. The expressions posed by the model, unseeen by the observer, were guessed at greater than chance accuracy simply by observing the face of the neonate, whose facial movements in the brow, eyes, and mouth regions provided evidence for imitation of the facial expressions.

Production and discrimination of facial expressions by preschool children.
Production and discrimination of the 8 basic facial expressions were investigated among 34 3-5-year-old preschool children. The children's productions were elicited and videotaped under 4 different prompt conditions (imitation of photographs of children's facial expressions, imitation of those in front of a mirror, imitation of those when given labels for the expressions, and when given only labels). Adults' "guesses" of the children's productions as well as the children's guesses of their own expressions on videotape were more accurate for the happy than afraid or angry expressions and for those expressions elicited during the imitation conditions. Greater accuracy of guessing by the adult than the child suggests that the children's productions were superior to their discriminations, although these skills appeared to be related. Children's production skills were also related to sociometric ratings by their peers and expressivity ratings by their teachers. These were not related to the child's age and only weakly related to the child's expressivity during classroom free-play observations.

Discrimination of facial expressions by preschool children.
This study investigated preschool children's ability to discriminate and categorize facial expressions. Children were shown drawings of persons with expressions of joy, sadness, surprise, and anger and asked to choose from an array of drawings the face that felt "the same" as the standard. The choice array varied on 1 or more features of the standard's expression or had identical key facial elements. In some cases the match had identical facial features and in others the match was a generalized version with no identical features. Children were given various prompts to select the accurate match for the standard. Both with and without prompts children made fewer errors matching happy expressions and matched generalized happy expressions as accurately as identical expressions. Surprised and angry faces were less accurately matched. Providing verbal labels for the faces facilitated matching, particularly for happy and generalized expressions, suggesting that labeling or explicitly providing a conceptual category may aid comparison and/or memory of the expressions. A levels-of-processing effect is suggested to be operating in young children's discrimination and categorization of facial expressions.

Respiratory distress syndrome: perinatal prediction of one year development outcome.
A number of perinatal variables were entered into multivariate regression analyses to determine which variables predicted the one-year Bayley Mental and Motor scores of 46 infants surviving the respiratory distress syndrome. Significant predictors were gestational age, 5 minute Apgar scores, obstetric complications, duration of IPPV and intensive care. Although gestational age was the strongest single predictor of developmental outcome, its predictive power was enhanced by the addition of the other significant perinatal variables. A greater number of the RDS infants received low motor scores as opposed to low mental scores, suggesting that intervention efforts with this group might focus on the development of early sensorimotor skills.

Effects of Brazelton demonstrations for mothers on the development of preterm infants.
Thirty healthy preterm infants were randomly assigned either to a control group or to one of two experimental groups. The mothers of the first experimental group were present during an administration of the Brazelton Neonatal Behavioral Assessment Scale and were asked to complete the Mother's Assessment of the Behavior of Her Infant Scale (MABI) at birth and weekly for four weeks after the discharge of their infants. The mothers of the second experimental group were not present during the administration of the Brazelton scale, but were asked to complete the MABI scale at birth and weekly for the first month after discharge. The mothers of the control infants did not observe administration of the Brazelton scale or complete the MABI scale, but were asked to complete a questionnaire on the developmental milestones of their infants. At 1, 4, and 12 months of age these infants were visited in their homes by teams of researchers blind to the hypothesis of the study and to the group assignment of the infants. The results at 1 month demonstrated that the experimental groups performed more optimally on the Brazelton scale interactive process items. These infants also received superior ratings on the video-taped feeding and face-to-face play sequences. At 4 months the experimental group infants showed better fine motor-adaptive abilities on the Denver Developmental Screening Test than did the control group. In addition, the face-to-face interaction ratings of the two experimental groups were significantly better that were those of the control group. The Bayley Scales of Infant Development were administered when the infants were 12 months corrected age. The infants of the experimental groups received significantly higher scores on the Mental Development Scale. This study suggests that teaching mothers the amazing skills of their newborns on the Brazelton and MABI scales may facilitate early interactions which, in turn, may contribute to early cognitive development.

Teenage, lower-class, black mothers and their preterm infants: an intervention and developmental follow-up.
To assess the combined risks of being born preterm and to a teenage mother, and to evaluate the effects of an early intervention, preterm infants born to lower-class, black, teenage mothers were provided a home-based, parent-training intervention, and their development was then compared with that of nonintervention controls, of term infants of teenage mothers, and of term and preterm infants of adult mothers. Despite equivalence on prenatal care, factors which placed the preterm infant of the teenage mother at greater risk at birth were the small-for-date size of the infant and the less realistic developmental milestones and child rearing attitudes expressed by the mother. The preterm infants of teenage mothers who received intervention showed more optimal growth, Denver scores, and face-to-face interactions at 4 months. Their mothers rated their infants' temperaments more optimally, expressed more realistic developmental milestones and child-rearing attitudes, and received higher ratings on face-to-face interactions. At 8 months, the intervention group received superior Bayley mental, Caldwell, and infant temperament scores.

Visual and cardiac responses to animate and inanimate faces by young term and preterm infants.
Infants' looking and looking-away behaviors, as well as cardiac responses to mothers' spontaneous and imitative and to dolls' animated and still faces, were recorded for 18 term and 18 preterm infants when they were 3 months old. Infants spent less time looking at their mothers' than at the doll's faces, and their heart-rate levels were elevated while looking at mothers' faces. These effects were most pronounced for the preterm infants whose inferior scores on the animate visual item of the Brazelton neonatal scale suggested a continuity of visual inattentiveness to animate stimuli. Both groups also looked at the inanimate more than the animate doll's face and evidenced lower heart-rate levels during that situation. An information-processing/arousal-modulation interpretation was made for infant looking-away behavior and elevated heart rate during the more arousing mother's-face situations.

Mother's assessments of term and pre-term infants with respiratory distress syndrome: reliability and predictive validity.
Assessments of term and preterm RDS infants were made by mothers on an adaptation of the Brazelton scale. The mother's assessments were not significantly different from those assessments made by trained clinicians, and both mothers and clinicians assigned less optimal ratings to the preterm infants. These ratings were correlated with Bayley motor scores at eight months. Mothers' assessments of infant temperament were made at four and eight months. These temperament ratings were significantly correlated with each other and with clinicians' ratings on the Brazelton neonatal and eight-month-Bayley Scales. These findings suggest that mothers' assessments are reliable and have some predictive validity during early infancy.

Developmental effects of prolonged pregnancy and the postmaturity syndrome.
The development of 40 postterm, postmature infants was compared to that of 40 normal control infants during the first year of life. The postterm, postmature infants had more prenatal complications and received lower Brazelton interaction and motor scores at birth. At four months they scored lower on the Denver developmental scale and were rated "difficult" babies by their mothers. At eight months their Bayley motor scores were equivalent to those of the control infants, but their mental scores were lower. At this time their mothers reported a higher incidence of illnesses and of feeding and sleep disturbances.
