The current study explored the potential influence of infant sleep, measured by parental report and actigraphy, and family functioning on attention development using eye tracking. The use of actigraphy in parallel with parental report, has the advantage of measuring participant's sleep throughout the night without parental observation and the ability to objectively assess sleep quality. An eye-tracking version of the Gap-Overlap task was used to measure visual attention. Questionnaires and behavioural assessment were used to assess family function, and general cognitive development. Fifty infants ( = 13.44 months, = 3.10) participated in the study, 23 of which had full final datasets. Results show that daytime sleep duration, as measured by parental report, and proportion of light sleep at night, as measured by actigraphy, are linked to visual attention. A higher proportion of light sleep, a marker of poorer sleep quality, and less daytime sleep were negatively linked with facilitation and disengagement on the Gap-Overlap task. Family functioning was not associated with attention. The results provide initial evidence that in addition to the amount of daytime sleep; quality of night-time sleep as measured by proportion of light sleep, is a potentially useful sleep variable which requires further focus in the study of attention development.
本研究通过父母报告和活动记录仪测量婴儿睡眠情况，并利用眼动追踪技术探究婴儿睡眠及家庭功能对注意力发展的潜在影响。将活动记录仪与父母报告结合使用，其优势在于可在无父母观察的情况下测量参与者整晚的睡眠情况，并能客观评估睡眠质量。采用眼动追踪版的间隙重叠任务来测量视觉注意力。通过问卷调查和行为评估来评定家庭功能以及一般认知发展情况。五十名婴儿（平均年龄 = 13.44个月，标准差 = 3.10）参与了本研究，其中23名拥有完整的最终数据集。结果显示，通过父母报告测得的白天睡眠时间，以及通过活动记录仪测得的夜间浅睡眠比例，均与视觉注意力相关。较高比例的浅睡眠（睡眠质量较差的一个指标）以及较少的白天睡眠时间，与间隙重叠任务中的促进和脱离呈负相关。家庭功能与注意力无关。研究结果提供了初步证据，表明除了白天睡眠时间外，以浅睡眠比例衡量的夜间睡眠质量，是一个潜在有用的睡眠变量，在注意力发展研究中需要进一步关注。
