ABSTRACT

Background

In this study we aimed to explore how intelligence and executive functioning are related to decision-making regarding social situations in persons with mild ID.

Method

We studied 80 vocational school students with mild ID; the controls were 80 students of a similar age. We assessed decision-making ability with the Important Life Decisions Task. Intelligence was assessed with the Wechsler Adult Intelligence Scale – Revised (WAIS-R), and executive functioning with the Wisconsin Card Sorting Test (WCST).

Results

The WAIS-R Verbal Comprehension and the Memory/Freedom From Distractibility factors predicted the decision-making score. Executive functioning was not related to decision-making. There was no interaction between the group and other variables.

Conclusions

Verbal intellectual abilities and abilities related to short-term memory and attention play an important role in decision-making regarding social situations. The difference in performance between persons with ID and the control group should be regarded as quantitative and not qualitative.

轻度智力障碍者的决策：与智力的关系和执行功能的测量

摘要

背景

在这项研究中，我们旨在探讨智力和执行功能如何与轻度 ID 患者的社交情境决策相关。

方法

我们研究了80名轻度ID的职业学校学生；对照组是 80 名年龄相近的学生。我们通过重要的生活决策任务评估决策能力。使用韦克斯勒成人智力量表 - 修订版 (WAIS-R) 评估智力，并使用威斯康星卡片分类测试 (WCST) 评估执行功能。

结果

WAIS-R 语言理解和记忆/免于分心因素预测了决策得分。执行功能与决策无关。该组与其他变量之间没有交互作用。

结论

言语智力和与短期记忆和注意力相关的能力在有关社交场合的决策中起着重要作用。ID 患者与对照组之间的表现差异应视为定量而非定性。
