自闭症谱系障碍（ASD）儿童表现出日常认知灵活性缺陷，但实验室数据并不令人信服。目前的研究旨在弥合这一差距。31名ASD儿童（8-12岁）和31名年龄和智商匹配的典型发育儿童进行了性别情感转换任务。突然的开关和复杂的刺激（情绪化的面孔）改善了生态有效性;最小的工作记忆负荷防止了研究结果中的偏见。两组的总体表现没有差异，但在ASD组的一部分表现缓慢且不准确。此外，在ASD组中，从情感到性别的转换比反之亦然要慢。ASD儿童在生态有效转换任务上没有表现出困难，但在情感任务集上却难以脱离。
Children with autism spectrum disorders (ASDs) show daily cognitive flexibility deficits, but laboratory data are unconvincing. The current study aimed to bridge this gap. Thirty-one children with ASD (8-12 years) and 31 age- and IQ-matched typically developing children performed a gender emotion switch task. Unannounced switches and complex stimuli (emotional faces) improved ecological validity; minimal working memory-load prevented bias in the findings. Overall performance did not differ between groups, but in a part of the ASD group performance was slow and inaccurate. Moreover, within the ASD group switching from emotion to gender trials was slower than vice versa. Children with ASD do not show difficulties on an ecological valid switch task, but have difficulty disengaging from an emotional task set.
