本研究的目的是调查是否缓慢的认知克里思（SCT）症状与神经认知任务的表现和现实世界的执行功能（EF）在学龄前儿童的注意力缺陷/多动障碍（ADHD）的风险评级。父母和老师评定的SCT症状和神经心理任务的性能和EF在61个4岁的学龄前儿童（51个男孩，10个女孩）与自我调节困难的评级之间的关联进行了检查，与回归分析控制ADHD注意力不集中症状的影响。在研究样本中，较高的教师评定的SCT症状与视觉感知能力，听觉和视觉注意力，持续和选择性注意力，抑制控制，前数字/数字概念和较慢的处理速度任务的表现较差显着相关，但SCT症状与工作记忆，注意力转移或认知灵活性控制ADHD注意力不集中时没有显着相关。较高的父母评分SCT症状与视觉感知能力显著相关。ADHD注意力不集中症状与日常生活EF评分的相关性比SCT更强;在控制ADHD注意力不集中后，父母或教师评定的SCT症状与抑制、工作记忆或计划/组织的日常生活评分均无显著相关性。这项研究表明，SCT症状有助于EF赤字至少在神经认知任务评估视觉感知/空间能力，注意细节和处理速度，在这个样本中观察到的幼儿多动症的风险，并可能是一个重要的干预目标。
The aim of this study is to investigate whether sluggish cognitive tempo (SCT) symptoms are associated with neurocognitive task performance and ratings of real-world executive functioning (EF) in preschoolers at risk for attention-deficit/hyperactivity disorder (ADHD). The associations between parent- and teacher-rated SCT symptoms and neuropsychological task performance and ratings of EF in 61 4-year-old preschool children (51 boys, 10 girls) with self-regulation difficulties were examined, with regression analyses controlling for the effects of ADHD inattention symptoms. In the study sample, higher teacher-rated SCT symptoms are significantly associated with poorer performance on tasks of visual-perceptual abilities, auditory and visual attention, sustained and selective attention, inhibitory control, pre-numerical/numerical concepts, and slower processing speed, but SCT symptoms are not significantly associated with working memory, attention shifting or cognitive flexibility when controlling for ADHD inattention. Higher parent-rated SCT symptoms are significantly associated with visual-perceptual abilities. ADHD inattention symptoms are more strongly associated than SCT with daily life EF ratings; neither parent- nor teacher-rated SCT symptoms are significantly associated with daily life ratings of inhibition, working memory, or planning/organization after controlling for ADHD inattention. This study suggests that SCT symptoms contribute to EF deficits at least on neurocognitive tasks assessing visual-perceptual/spatial abilities, attention to detail and processing speed, as observed in this sample of young children at risk for ADHD, and may be an important intervention target.
