DESCRIPTION (provided by applicant): The purpose of the proposed project is to provide an opportunity for postdoctoral training in the areas of fetal neurobehavioral development, maternal stress physiology during pregnancy, and the use of psychophysiological measures in mother-infant dyads. Specifically, the project is designed to examine the gestational roots of mother-infant dyadic synchrony. Synchronous dyadic interactions are an important aspect of the mother-infant relationship and are believed to facilitate perceptual processing, secure attachment, and both physiological and affective homeostatic regulation. Recent research indicates that synchrony has its roots during the prenatal period. DiPietro and colleagues (2004; in press) have observed biobehavioral synchrony in maternal-fetal dyads that consists of temporal associations between fetal movement and maternal heart rate and skin conductance. The degree of linkage between fetal movement and maternal response is consistent across gestation and appears to represent stable individual differences between maternal-fetal pairs. The specific aims of the proposed project are 1) to determine if maternal and fetal behavioral and physiological reactivity to stress during gestation are associated with individual differences in maternal-fetal biobehavioral synchrony; 2) to determine if the degree of maternal-fetal biobehavioral synchrony during gestation is associated with individual differences in maternal physiological reactivity to child distress and maternal sensitivity during early childhood; and 3) to determine if the degree of maternal-fetal biobehavioral synchrony during gestation is related to individual differences in maternal-child behavioral and physiological synchrony during early childhood. A secondary data analysis will be conducted to determine if maternal and fetal reactivity to induced maternal stress are related to maternal-fetal biobehavioral synchrony. A follow-up is also proposed for an ongoing project to examine potential links between maternal-fetal synchrony and maternal-child synchrony during a free-play session. Maternal and child behavioral and physiological reactivity and regulation during three standardized Laboratory Temperament Assessment Battery vignettes will also be examined as potential moderators of this relationship. Research has repeatedly demonstrated the importance of early social interactions for the development of regulatory abilities and stress responsive physiology. Understanding the origins of the mother-infant relationship may have implications for interventions in the early environment that could have repercussions for both physical and mental health well into adulthood.

描述（由申请人提供）：拟议项目的目的是为胎儿神经行为发育，怀孕期间的孕产妇应激生理学以及在母型二元组中使用心理生理测量的领域提供机会。具体而言，该项目旨在检查母二元同步的妊娠根。同步二元相互作用是母亲关系的重要方面，被认为可以促进感知处理，安全的依恋以及生理和情感稳态调节。最近的研究表明，同步在产前时期具有根源。 Dipietro及其同事（2004年；印刷中）观察到在母亲 - 狂欢二元组中的生物行为同步，包括胎儿运动与母体心率和皮肤电导之间的时间关联。胎儿运动和母体反应之间的联系程度在妊娠之间是一致的，似乎代表了母亲对之间的稳定个体差异。拟议项目的具体目的是1）确定妊娠期间母体和胎儿的行为和生理反应性是否与母亲 - 宠物生物行为同步的个体差异有关； 2）确定妊娠期间母亲 - 孕产物生物行为同步的程度是否与儿童幼儿对儿童困扰和孕产妇敏感性的孕产妇生理反应性的个体差异有关； 3）为了确定妊娠期间的母亲狂热生物行为同步的程度是否与幼儿期间母子行为和生理同步的个体差异有关。将进行二次数据分析，以确定母体和胎儿对诱发的母体应激是否与母亲 - 狂热生物行为同步有关。还提出了一个正在进行的项目的后续行动，以检查在自由活动中产妇同步与母子同步之间的潜在联系。在三个标准化实验室气质评估电池电池中，母亲和儿童的行为和生理反应性和调节也将被视为这种关系的潜在主持人。研究反复证明了早期社会互动对制定监管能力和压力响应式生理的重要性。了解母亲关系的起源可能对早期环境中的干预措施有影响，这可能会影响到成年后的身心健康。
