One hundred six infants participated in a longitudinal study of cognition-emotion integration exploring the effects of attentional control on regulation of negative affect across infancy. At both 5 and 10 months, attentional control was measured behaviorally (looking time to neutral stimulus), physiologically (cardiac reactivity), and with temperament-based parental ratings of orienting/regulation. Looking and cardiac measures were examined both before and after a mild stressor. At 5 months, post-distress negative affect was related only to distress-related increases in heart rate. At 10 months, however, behavioral, cardiac, and parent-report aspects of attentional control explained unique variance in post-distress negative affect. Attentional control measures at 5 months did not predict negative affect at 10 months. This pattern of results is discussed with respect to the development of frontally mediated regulatory mechanisms from infancy into early childhood.
一百零六名婴儿参与了一项关于认知-情绪整合的纵向研究，该研究旨在探索注意力控制对婴儿期负面情绪调节的影响。在 5 个月和 10 个月大时，通过行为（注视中性刺激的时间）、生理（心脏反应）和基于气质的父母定向/调节评分来测量注意力控制。在轻度应激前和应激后都检查了注视和心脏测量。在 5 个月时，应激后负性情绪仅与心率与应激相关的增加有关。然而，在 10 个月时，注意力控制的行为、心脏和家长报告方面解释了应激后负性情绪的独特差异。5 个月时的注意力控制测量不能预测 10 个月时的负性情绪。讨论了这一结果模式，涉及从婴儿期到幼儿期额叶介导的调节机制的发展。
