Over the past two decades, technological and medical advances have resulted in increasing survival and decreasing morbidity for infants who are termed high risk due to prematurity and associated factors. As professionals began to turn their attention toward optimizing the long-term outcome for these infants, a number of pro̧grams collectively known as “infant stimulation” programs were developed. The design and implementation of these programs initially were based on findings from the basic sciences that indicated that environmental enrichment positively affected the immature nervous system, whereas environmental deprivation had adverse effects. Subsequent clinical research that analyzed the effects of stimulation programs for infants in high-risk nurseries has shown beneficial effects of varying types of stimulation on numerous dependent measures. Recently, however, some practitioners have cautioned against viewing these results as conclusive. This article is a review of multi-disciplinary research relevant to infant stimulation programs and includes a critical analysis of research findings and future needs. This analysis leads to the conclusion that many infant stimulation programs have been designed and implemented based on potentially invalid assumptions. Further research is needed prior to establishing what constitutes an optimal infant stimulation program. 相似文献

Head orientation was investigated in a longitudinal study of 37 infants, who were observed at ages 2, 4, 8, and 12 weeks, during a 60-second period that followed each of four (60 second) midline or lateral holds. When newborn, the infants tended to lie with their heads to the right, but this bias weakened over the first 3 postnatal months. This rightward motor bias was constrained further by such factors as sex and holding position; both factors had their strongest effect at 8 weeks. Finally, evidence was found for behavioral reorganization of postural orientation such that head orientation was less influenced by prior head positioning after than prior to 8 weeks. 相似文献

Stepping movements were investigated for evidence of early motor asymmetry in 24 familial right-handed infants and 14 familial left-handed infants at each of five ages: 2–3 days after birth, 14 days, and 1, 2, and 3 months of age. Results indicated a nonsignificant right leg advantage during the newborn period, with few significant lateral preferences evidenced in either direction at later testing ages. These results fail to indicate that a reliable leg preference persists beyond the newborn period, particularly among familial right-handed infants. Thus, it seems unlikely that an asymmetry in stepping movements during early infancy marks the beginning of a direct developmental path that culminates in a motor asymmetry in later childhood. 相似文献

The relationship between infant state and head orientation after the head is held in a midline or lateral position was investigated longitudinally in infants 2, 4, 8, and 12 weeks of age. Across the four ages, there was a general decrease in the amount of time spent in an active-awake state, whereas the amount of time spent crying remained fairly stable. Overall, infants turned more often to the right than to the left, but this difference was more pronounced when the infants were quietly alert or active-awake than when they were crying. The results thus indicate that state variables influence the expression of headorientation biases in early infancy. 相似文献

Lateral preferences in parents' cradling and holding of their infants were assessed in a longitudinal study commencing 1–3 days after birth and ending at 18 months. Right-handed parents showed a consistent left-side preference, which declined slightly as the infants grew older. Left-handed mothers showed an initial left-side preference and then more variable holding behavior, including right-side preferences, in some conditions. No relationship between the parents' holding behavior and two measures of infant head posture was found. It is suggested that parental side-holding preferences and infant head orientation biases are components of a biobehavioral system designed to enhance the organization of the caregiver-infant relationship. 相似文献
