Abstract

This study investigated the association of sluggish cognitive tempo (SCT), processing speed, and executive function (EF) in children with specific learning disabilities (SLD), and the typically developing children (TD) (60 female students aged between 8 and 10). Child and Adolescent Behavior Inventory-Parent Version (CABI), the Barkley Deficits in Executive Functioning Scale-Children and Adolescents (BDEFS-CA), and Wechsler Intelligence Scale for Children-IV (the Processing Speed Index (PSI) were used to assess SCT, processing speed, and EF. The results showed that SCT problems were higher in children with SLD (p < 0.001). In addition, results showed that children with SLD had poorer performance on processing speed (p < 0.001) compared to the TD group. Executive dysfunctioning in self-management to time, self-organization, problem-solving, self-restraint, self-motivation, and self-regulation of emotions were poorer in children with SLD than TD group (p < 0.05). This study provides initial evidence that SCT symptoms are poor in female children with SLD, and associated with executive dysfunction and poor processing speed.

摘要

本研究调查了特定学习障碍 (SLD) 儿童和典型发育儿童 (TD)（60 名 8 至 10 岁的女学生）迟缓认知节奏 (SCT)、处理速度和执行功能 (EF) 之间的关系. 儿童和青少年行为量表-父母版 (CABI)、巴克利执行功能缺陷量表-儿童和青少年 (BDEFS-CA) 和韦氏儿童智力量表-IV（处理速度指数 (PSI)）用于评估 SCT , 处理速度, 和 EF。结果显示 SLD 儿童的 SCT 问题更高 ( p  < 0.001)。此外，结果显示 SLD 儿童在处理速度上表现较差 ( p < 0.001) 与 TD 组相比。与 TD 组相比，SLD 儿童在时间自我管理、自我组织、解决问题、自我约束、自我激励和情绪自我调节方面的执行功能障碍更差（p  < 0.05）。这项研究提供了初步证据，表明患有 SLD 的女童的 SCT 症状较差，并且与执行功能障碍和处理速度较差有关。
