Cognitive flexibility has been measured with inductive reasoning or explicit rule tasks in individuals with autism spectrum disorders (ASD). The Flexible Item Selection Task (FIST) differs from previous cognitive flexibility tasks in ASD research by giving children an abstract, ambiguous rule to switch. The ASD group (N = 22; Mean age = 8.28 years, SD = 1.52) achieved a lower shift percentage than the typically developing verbal mental-age control group (N = 22; Mean age = 6.26 years, SD = 0.82). There was a significant positive correlation between verbal mental age and shift percentage for children with ASD. Group differences on the FIST converge and extend prior evidence documenting an impaired ability to adapt rapidly to changes in task demands for individuals with ASD.
认知灵活性已通过自闭症谱系障碍(ASD)个体的归纳推理或显式规则任务进行测量。与 ASD 研究中的先前认知灵活性任务不同,灵活项目选择任务(FIST)为儿童提供了一个抽象的、模糊的规则来切换。与具有典型语言发育的对照组(N=22;平均年龄=6.26 岁,标准差=0.82)相比,ASD 组(N=22;平均年龄=8.28 岁,标准差=1.52)的转换百分比较低。对于 ASD 儿童,言语心理年龄与转换百分比之间存在显著正相关。FIST 上的组间差异与先前的证据相吻合,这些证据记录了 ASD 个体快速适应任务需求变化的能力受损。
