Infant cortisol and behavioral responses to receiving one versus two inoculations on one pediatric office visit were observed at two and six months of age. The findings indicate a developmental trend for a decline over age in adrenocortical reactivity to inoculation for infants showing a cortisol release following perturbation. Results were…

This study systematically investigated the influence of direction and frequency of rocking on the activity of two-month-old infants. Of the 84 subjects, 42 were males and 42 females. They were brought to the laboratory at least 2 hours after each feeding and placed supine in a bassinet. Rocking at 60 cycles per minute resulted in a greater…

Reports on a strategy of continuous measurement of the frequency of the same infant behavior over time, which was applied to measuring infant development in the prone position, namely, chin lifting, chest lifting, and a creeping response. (BD/BR)

In this study, an attempt was made to determine whether psychophysiological differences existed between 20 prematurely born and 20 full-term infants in their responsiveness to tactile stimulation and in their ability to discriminate among different intensities of such stimulation. (Author/SB)

Compared the spontaneous leg movements of 10 infants with Down Syndrome to those of nondisabled infants matched for chronological age and motor age. Contrary to expectations, no significant difference was found in the frequency of leg movements between the two groups. However, Down Syndrome subjects demonstrated significantly fewer of the most…

An investigation was made of the behavioral effects of caffeine in a sample of 313 newborns and their mothers. A weighted measure of caffeine based on daily ingestion of coffee, tea, and cola was derived from a maternal interview. The majority of mothers consumed the equivalent of about 1.3 cups of coffee per day. Infant outcome measures included…

Contending that developmental disability is defined by cognitive and affective performance as well as hazardous biological events, the authors consider multiple factors as cumulative in placing an infant at risk for future developmental disability. A risk scoring system based on biological and behavioral factors in an additive manner is presented.…

Reports on a portion of a long-term investigation carried out to determine the prognostic significance of newborn behavioral assessments for later development and behavior, in terms of identifying a subpopulation which would be a high risk group. (Author/SDH)

This study examined behavioral correlates of the rapid central nervous system changes occurring in the first 4 months of life. It was hypothesized that during the early months of infancy, visual preference would occur as a function of quantitative dimensions of the stimuli (size) which could be mediated at a subcortical level. It was further…

An infant's unique style and temperament is thought to develop during a given small time segment as a consequence of the initiatives taken by caretaker or infant; usually an interaction of the two. (WY)

Examines the development of normative sleep-wake state characteristics in full-term infants, and atypical state characteristics as presented in several clinical populations including preterm and autistic children. Reviews and critiques the literature on the usefulness of infant state parameters in predicting developmental outcomes of infants at…

This study tests the proposition that selective behaviors of both mother and infant during feeding are predictors of weight gain during the first month of life. Forty normal mother-neonate pairs were studied, and the target behaviors were examined using an adaptation of the techniques developed by Brown and Bakeman (in which approximately 60…

Reviews different approaches used over the past two decades to study early behavioral development in infants. Reviews research in areas as physical and cognitive development and the role of adult caretakers. (BD)

Examined cardiac activity during the first 13 months of life. Indexes of cardiac activity changed in an orderly way with development. There were intercorrelations among the cardiac measures. Analyses indicated that measures of heart-rate variability were significantly higher in insecure children than in secure children. (BC)

Part One of these hearings before the Select Committee on Nutrition and Human Needs of the United States Senate includes the testimony of scientists and doctors engaged in research regarding the relationship between maternal, fetal, and infant nutrition and optimum mental and physical development of the child. In testimony it was shown that the…
