ABSTRACT This longitudinal study examined whether the cognitive and academic development of children (Mage = 10.52 years) with Borderline Intellectual Functioning (BIF), is characterized by developmental delay or atypical development. Cognitive tasks, arithmetic tasks, and reading tasks were administrated during three succeeding years to the BIF group and a Chronological Age-Matched Comparison (CAMC) group. The BIF children displayed weaknesses in relation to all tasks, and slower developmental rates on four arithmetic tasks and word reading. The results provide evidence in support of the developmental delay model as the BIF children overall displayed similar developmental growth and trends as the CAMC group.

9 至 10 岁边缘智力功能儿童认知功能和学业技能的发展

摘要 这项纵向研究检查了具有边缘智力功能 (BIF) 的儿童（Mage = 10.52 岁）的认知和学业发展是否以发育迟缓或非典型发育为特征。认知任务、算术任务和阅读任务在 BIF 组和时间顺序年龄匹配比较 (CAMC) 组的连续三年内进行。BIF 儿童在所有任务中都表现出弱点，在四项算术任务和单词阅读方面的发展速度较慢。结果提供了支持发育迟缓模型的证据，因为 BIF 儿童总体上显示出与 CAMC 组相似的发育增长和趋势。
