Validation of infant behavior identified by neonatal nurses.

Nurses observe that the behavior of an occasional full-term healthy newborn is "unusual," "different," "funny," or "not like the others." This study was designed to determine whether infants identified by nurses as suspect behaved differently from those identified as normal. Suspect infants scored significantly lower on the Brazelton Neonatal Behavior Assessment Scale than their matched controls. No dysfunction was common across the entire suspect group. Although nurses accurately predicted suspect infant behavior, they did not identify the specific Brazelton dimensions on which infants demonstrated worrisome behavior. The results indicated that nurses are reliable sources of information about infant behavior and can be valuable aids in screening infants in need of further assessment. In addition, the data provided tentative insight into the methods nurses use to make clinical judgments. Finally, the results pointed to the possible limitations of the medical model of infant assessment and demonstrated that nurses' empirical knowledge is amenable to measurement and testing. Additional research is necessary to determine if and under what circumstances infants who behave suspiciously are at risk.

The relationship of obstetric ultrasound to parent and infant behavior.

There is inconsistency in the obstetric literature regarding the relationship between the mother's knowledge of fetal health gained by ultrasound and maternal psychological attachment to the fetus. To evaluate the relationship more precisely, this study assessed variables of physician-patient interaction, parental mental health in pregnancy and infancy, and 3-month infant and parent behavior. The results show that maternal mental health scores increased as a function of the stress associated with an "at risk" pregnancy necessitating ultrasound assessment. As the parent received more definitive information, scores on measures of anxiety, depression, and hostility decreased. There was no significant relationship, however, between definitive information gained through ultrasound and later parent and infant behavior in play interaction. Shifts in fetal and neonatal health status and the positive interaction between physician and parent suggest the need for further analysis.

Cocaine and infant behavior.

Prenatal and early postnatal cocaine exposure may have lasting effects on brain development. Whereas adverse behavioral outcomes in exposed infants are plausible, they have not yet been well defined, due to methodological limitations of published studies. Improved research and clinical programs are needed to serve drug-exposed infants and their families.

The effects of varying environmental demands on maternal and infant behavior.

3 groups of macaque mother-infant dyads were observed while each lived in ecological settings that differed in their level of foraging demand and, hence, the amount of work each mother was required to perform to obtain her daily rations. 2 groups (LFD and HFD) lived in stable low- and high-demand environments, respectively. The third group (VFD) lived in a variable-demand environment in which 2-week periods of HFD and LFD conditions were alternated, without external cues. Observations suggested that VFD subjects were unable to predict or rapidly adapt to the biweekly changes in food availability. Whereas LFD adults scored lowest in dominance-related behaviors and highest in affiliative behavior (social grooming), VFD adults showed the highest levels of dominance patterns and the lowest levels of grooming. VFD infants showed the most sustained clinging to mother, the lowest levels of social play and exploration, the highest levels of affective disturbance, and repeated evidence of depression as the study progressed. These findings suggest that in monkeys, as in humans, when, because of competing demands, mothers are psychologically unavailable to their infants, attachments are less secure, normal development is disrupted, and psychopathological patterns are more likely to emerge.

Sex differences in parent and infant behavior in the home.

Observations were made in the homes of 32 families, each with a child aged around 12 or 24 months. 16 of the children were boys and 16 girls. Boys showed more active play, play with transportation toys, and play generally forbidden by parents. Girls played more with soft toys and dolls. On questionnaire responses many parents rated these and other behaviors as sex appropriate. However, actual sex differences in immediate parental response to children were few or undetected. Sex differences in children's behavior did not appreciably increase from 12 to 24 months. Also, there was no correlation with how stereotyped parents' questionnaire responses were and the degree to which their children exhibited sex-typed behavior.

B. F. Skinner's legacy to human infant behavior and development.

B. F. Skinner's legacy to human behavioral research for the study of environment-infant interactions, and indeed for the conception of development itself, is described and exemplified. The legacy is largely the practicality, the efficiency, and the comparative advantage--relative to diverse other behavioral and nonbehavioral approaches--of using the operant-learning paradigm to organize and explain many of the sequential changes in behavior patterns conventionally thought to constitute infant development.

Nutrition and infant behavior: a replication study in the Katmandu Valley, Nepal.

As a cross cultural comparison with an earlier study done in West Bengal, behavioral observations were made in the Katmandu Valley of 36 well-nourished and 38 undernourished children, 7 to 18 months of age, and their mothers. Undernourished children showed lowered levels of exploratory activity and attachment behavior, especially distance interaction, and a heightened need for physical closeness to the mother. Moreover, among the undernourished children the level of intellectual performance and the overall time spent in play were decreased, while time spent sucking at the breast was increased. In contrast to the West Bengali study, maternal behavior showed no differences between the two nutritional groups, and the intercorrelations between maternal and child scores showed similar or parallel patterns of reciprocity for the well-nourished and the undernourished children. No sex or age differences were found. The findings were interpreted to support Levitsky and Barnes' hypothesis of "functional isolation" as a mechanism between undernutrition and environmental stimulation to produce long-term behavioral changes. In addition, hunger as a motivational state, expressed as increased sucking, may interfere with other motivational determinants that might lead to exploration and/or increased social contacts.

The relationship between physical growth and infant behavioral development in rural Guatemala.

The present study investigated the relationship between a number of anthropometric indices and behavioral development during the first 2 years of life in rural Guatemala. Length and weight were the indices most strongly correlated with behavioral development. If the effect of the infant's length and weight was statistically controlled for, none of the other anthropometric variables explained a significant proportion of the variance in behavioral development. Controlling the length (or weight) assessed at the same age as the behavioral assessment, length (or weight) for younger ages was not significantly correlated with behavioral development. Changes in length or weight over time correlated with changes in behavioral performance. We were unable to explain the association between physical growth and behavioral development by a number of variables including gestational age, nutrient intake, prevalence of disease, and familial characteristics.

Infant behavior and maternal adaptations in the first six months of life.

This study explored the relationship among infant temperament, maternal concern, and adjustment during early infancy, and the stability of these variables over time. Infants identified as difficult were found to change considerably across three time points (between five weeks and six months), suggesting the need for caution in prognostication with respect to temperament difficulties in infancy. Further implications for the care of young infants and their families are discussed.
