INTRODUCTION
This study examined whether IQ predicts neuropsychological performance among children with varying ability levels.
METHOD
177 children/adolescents were subdivided as Below Average (BA; N = 71; IQ = 60-85), Average (A; N = 72; IQ = 90-110), or Above Average (AA; N = 34; IQ = 115-140) in IQ. Assessments included intelligence, achievement, memory, and executive functioning measures.
RESULTS
Group differences were found on all tests (p < .001). Planned comparisons revealed differences between BA and A on seven variables, and between A and AA on five variables with small-to-medium effect sizes. Correlations were found between IQ and neuropsychological functioning and varied by group membership.
DISCUSSION
In children, IQ predicts neuropsychological performance differentially based upon ability level, with stronger relationships shown in lower IQ ranges.
简介
本研究考察了智商是否可以预测不同能力水平儿童的神经心理学表现。
方法
177 名儿童/青少年根据智商分为以下三组：低于平均水平（BA；N = 71；智商= 60-85）、平均水平（A；N = 72；智商= 90-110）或高于平均水平（AA；N = 34；智商= 115-140）。评估包括智力、成就、记忆和执行功能测试。
结果
所有测试均发现组间存在差异（p <.001）。计划比较显示，BA 组与 A 组在七个变量上存在差异，A 组与 AA 组在五个变量上存在差异，差异具有小到中等的效应量。智商与神经心理学功能之间存在相关性，相关性因群体成员而异。
讨论
在儿童中，智商根据能力水平对神经心理学表现的预测存在差异，在较低的智商范围内表现出更强的关系。
