Abstract
This investigation examines the association between risk status and the quality of emotional arousal and regulation among preterm infants in the second year of life. The behavior of 55 preterm infants stratified into three risk groups by severity and chronicity of respiratory illness was recorded during the procedures of the Strange Situation. Measures of emotional responsiveness included temporal and intensity features of facial and vocal expressions as well as concurrent activity with toys. Significant relationships between neonatal risk status and these expressive and regulatory features were observed. Infants in the High-Risk group ( N = 16) differed from healthy Low-Risk infants ( N = 23) and from those in the Moderate-Risk group ( N = 16). The High-Risk infants showed a greater sensitivity to distress arousal at low levels of stress and less ability to modulate distress once aroused. High-Risk infants also demonstrated significantly less adaptive play with toys than the other preterm infants. In short, this study suggests that, when placed under stress, High-Risk preterm infants in their second year of life become more distressed and demonstrate less ability to recover from this distress and effectively re-engage their environment than preterm infants born at lower risk.
