PROJECT SUMMARY The development of effective self-regulation skills is one of the most important achievements of early childhood. During infancy, key interconnected domains of self-regulation include emotion (i.e., distress regulation) and feeding (i.e., caloric intake regulation). An important foundation for infants’ developing capacities for self-regulation is caregivers’ sensitive responsiveness to infant behavioral cues, especially during feeding. However, given the ubiquity of portable technologies (e.g., smartphones), it is likely that many caregivers are distracted by technology while feeding their infants, which may lower sensitive responsiveness to infant cues. Surprisingly few studies have examined possible effects of technological distractors on the quality and outcome of early feeding interactions. The primary aim of the proposed research is to examine impacts of maternal technology use on early feeding interactions and change in these impacts across early infancy. We also aim to test the hypothesis that greater habitual maternal technology use will predict poorer infant emotion and intake regulation when infants are 6 and 12 months of age, greater socioemotional and behavioral problems at 12 months, and greater infant weight gain between birth and 12 months. In addition, we aim to describe levels of and changes in habitual maternal technology use from the prenatal and early postpartum periods and examine predictors of habitual technology use patterns. We propose a 15-month longitudinal study with nested within-subject experimental studies and bursts of daily passive sensing of device use and time diaries. Pregnant women will be recruited and assessed during their 3rd trimester of pregnancy, then mother-infant dyads will be assessed when infants are 2wk, 4mo, 6mo, 9mo, and 12mo of age. At 2wk and 4mo, mothers and infants will be observed feeding under 3 counterbalanced within-subject experimental feeding conditions: 1) Control, 2) TV Use, 3) Mobile Device Use. Videos of these feeding interactions will be coded to obtain a comprehensive understanding of potential impacts of maternal technology use on maternal attention, sensitivity to infant cues, and engagement of the infant, and on infant clarity of cues, attentional responsiveness to the mother, and intake. Infant emotion and intake regulation, and related socioemotional and behavioral problems, will be assessed via a combination of established behavioral protocols and validated questionnaires. To describe patterns of habitual maternal technology use, we will integrate passive sensing (via an app) of maternal technology use with time diaries; hypothesized predictors include maternal depressive symptoms, stress, emotion regulation, feeding styles, and reflective functioning, and infant eating behaviors and temperament. In sum, the proposed research is an innovative, multi-level examination of potential impacts of maternal technology use on the quality and outcome of dyadic interactions during feeding. Findings from this study will provide a foundation for further research aimed at understanding how to balance potential benefits vs. drawbacks of technology use within family contexts.

项目摘要 有效的自我调节技能的发展是早期最重要的成就之一 童年。在婴儿期，关键的自我调节领域包括情绪（即困扰 调节）和进食（即热量摄入调节）。婴儿发展的重要基础 自我调节的能力是看护人对婴儿行为提示的敏感响应能力，尤其是在 进食。但是，鉴于便携式技术的无处不在（例如智能手机），很可能有许多 护理人员在喂养婴儿时会因技术分心，这可能会降低敏感的反应能力 给婴儿提示。令人惊讶的是，很少有研究检查技术干扰因素对 早期喂养相互作用的质量和结果。拟议研究的主要目的是检查 孕产妇技术使用对早期喂养相互作用的影响以及早期的这些影响的变化 婴儿期。我们还旨在检验以下假设，即更大的习惯​​性孕产妇使用将预测较差 婴儿的情绪和摄入调节，当婴儿6个月和12个月大，社会情感更大，并且 在12个月时的行为问题，出生到12个月之间的婴儿体重增加。另外，我们 旨在描述产前和早期使用惯常母校技术使用的水平和变化 产后时期并检查习惯技术使用模式的预测指标。我们提出了15个月的 纵向研究，嵌套受试者内实验研究和设备的每日被动灵敏度爆发 使用和时间日记。孕妇将在怀孕三个月期间招募和评估 然后，当婴儿为2WK，4MO，6MO，9MO和12MO年龄时，将评估母亲的二元组。 和4MO，将观察到母亲和婴儿在3个平衡下喂养的受试者内实验性喂养 进食条件：1）控制，2）电视使用，3）移动设备使用。这些喂养互动的视频将是 编码是为了获得对母体技术使用对孕产妇的潜在影响的全面理解 注意，对婴儿提示的敏感性以及婴儿的参与以及提示的婴儿清晰度，注意力 对母亲的反应和进气。婴儿情绪和摄入调节以及相关的社会情感 和行为问题，将通过既定的行为方案的结合进行评估并经过验证 问卷。为了描述习惯性孕产妇技术使用的模式，我们将整合被动感官 （通过应用程序）材料技术与时间日记一起使用；假设的预测因子包括材料抑郁 症状，压力，情绪调节，喂养方式和反射功能以及婴儿饮食行为 和温度。总而言之，拟议的研究是对潜在影响的创新，多层次的检查 在喂养过程中，孕产妇技术在二元相互作用的质量和结果上使用。从中的发现 研究将为进一步的研究提供一个基础，旨在了解如何平衡潜在利益 在家庭环境中使用技术使用的缺点。
