Difficulties with narrative have been reported in individuals diagnosed with autism spectrum disorder (ASD), but the role of executive function on narrative ability has not been examined in ASD. In this study, we aimed to (1) examine whether narrative abilities of ASD children differed from neurotypical (NT) children who did not differ in age, sex, and IQ; and (2) investigate relations between executive function and narrative ability in ASD children.
Narratives were elicited from 64 ASD children and 26 NT children using a wordless picture book and coded to derive several aspects of narrative ability such as propositions, evaluative devices, and self-repairs. Executive functions (specifically, inhibition and working memory) were measured using both experimenter-administered assessment and parent-report measures.
Compared to NT children, ASD children produced fewer propositions but did not differ in their use of evaluative devices and self-repairs during narrative production. Greater inhibitory challenges related to more self-repairs involving repetition of story elements, whereas working memory did not relate to any of the measures of narrative ability among ASD children.
This study revealed that narratives by verbally fluent ASD children were shorter and less complex than those by NT children but did not differ in the specific features of narratives. Furthermore, although ASD children did not make more self-repairs than NT children, difficulty with inhibition was related to more self-repairs, indicating more dysfluent narrative production in ASD children, which has implications for intervention.
据报道,被诊断患有自闭症谱系障碍(ASD)的个体在叙述方面存在困难,但执行功能对ASD患者叙述能力的作用尚未得到研究。在本研究中,我们旨在:(1)研究ASD儿童的叙述能力是否与年龄、性别和智商无差异的神经典型(NT)儿童不同;(2)调查ASD儿童执行功能与叙述能力之间的关系。
使用一本无字图画书从64名ASD儿童和26名NT儿童中引出叙述内容,并进行编码以得出叙述能力的几个方面,如命题、评价手段和自我修正。执行功能(具体而言,抑制和工作记忆)通过实验者实施的评估和家长报告的测量方法进行测量。
与NT儿童相比,ASD儿童在叙述过程中提出的命题较少,但在评价手段和自我修正的使用上没有差异。更大的抑制挑战与更多涉及故事元素重复的自我修正相关,而工作记忆与ASD儿童的任何叙述能力指标均无关联。
本研究表明,语言流畅的ASD儿童的叙述比NT儿童的叙述更短且更简单,但在叙述的具体特征上没有差异。此外,尽管ASD儿童的自我修正并不比NT儿童多,但抑制困难与更多的自我修正相关,这表明ASD儿童的叙述流畅性较差,这对干预具有启示意义。
