A comparative study of the behavior of Greek neonates
Insights
Adopted neonates from an orphanage and lower-class infants showed poorer behavioral development. Maternal medication temporarily affected middle-class infants, highlighting perinatal influences on neonatal behavior.
Area of Science:
- Neonatal development
- Perinatal psychology
- Child psychology
Background:
- Early neonatal behavior is crucial for development.
- Socioeconomic and environmental factors can impact infant behavior.
- Perinatal variables like maternal medication may influence neonatal outcomes.
Purpose of the Study:
- To compare neonatal behavior across different socioeconomic and environmental groups.
- To examine behavioral recovery curves in the first ten days of life.
- To identify factors affecting early neonatal behavior.
Main Methods:
- Evaluated 90 Greek neonates (30 per group: adoptive, lower-class, middle-class) at 1, 5, and 10 days postpartum.
- Utilized a 21-item behavioral scale and a 16-item neurologic evaluation.
- Analyzed group differences and recovery curves for interactive, motor, and state behaviors.
Main Results:
- Significant behavioral differences observed between groups.
- Adoptive infants from Metera orphanage exhibited the poorest performance.
- Middle-class infants showed initial deficits in physiologic, interactive, motor, and state behaviors, likely due to maternal medication, with subsequent improvement.
Conclusions:
- Intrauterine factors (e.g., nutrition) and environmental responses influence neonatal behavior.
- Maternal medication represents a significant perinatal variable affecting early infant behavior.
- Recovery curves demonstrate the dynamic nature of neonatal behavior and its sensitivity to perinatal influences.
Abstract:
Three groups of 30 Greek neonates each (an adoptive group from the Metera orphanage, a lower-class group, and a middle-class group) were evaluated at days 1, 5, and 10 after birth using a behavioral scale of 21 items and a neurologic evaluation of 16 items. Behaviors were examined for group differences and group-by-age recovery curves were determined during the first ten days. Significant differences were found in the separate items and items grouped to reflect interactive, motor, and state behavioral dimensions. The adoptive babies at the Metera orphanage generally performed the most poorly. This difference seems not only to reflect intrauterine differences, especially in regard to nutrition, but to point to the likelihood of eliciting less than optimal responses from future environments. The middle-class group had the worst scores on physiologic items and were similar to the Metera babies in having initially depressed interactive, motor, and state behavior. Improvement in these areas over ten days suggested that temporary effects of maternal medication caused the poor scores. The recovery curves of the infants pointed to the important effects of such perinatal variables as maternal medication on early neonatal behavior.
