This study analyzed the relation between mental time travel (MTT) and the ability to produce a storytelling focusing on global coherence, which is one of the most notable characteristics of narrative discourse. As global coherence is strictly tied to the temporal sequence of the events narrated in a story, we hypothesized that the construction of coherent narratives would rely on the ability to mentally navigate in time. To test such a hypothesis, we investigated the relation between one component of MTT-namely, episodic future thinking (EFT)-and narrative production skills by comparing the narratives uttered by 66 children with high-functioning autism spectrum disorder (ASD) with those produced by 66 children with typical development. EFT was assessed by administering a task with minimal narrative demands, whereas storytelling production skills were assessed by administering two narrative production tasks that required children to generate future or past episodes with respect to the target stimuli. The results showed that EFT skills were impaired only in a subgroup of children with ASD and that such subgroup performed significantly worse on the narrative production task than ASD participants with high EFT skills and participants with typical development. The practical and theoretical implications of these findings are discussed.
本研究分析了心理时间旅行(MTT)与生成注重全局连贯性的故事讲述能力之间的关系,全局连贯性是叙事话语最显著的特征之一。由于全局连贯性与故事中所叙述事件的时间顺序紧密相关,我们假设连贯叙事的构建将依赖于在时间中进行心理导航的能力。为了验证这一假设,我们通过比较66名高功能自闭症谱系障碍(ASD)儿童与66名发育正常儿童所讲述的故事,研究了MTT的一个组成部分——即情景未来思维(EFT)——与叙事生成技能之间的关系。EFT通过执行一项叙事要求极低的任务来评估,而故事讲述生成技能则通过执行两项叙事生成任务来评估,这两项任务要求儿童根据目标刺激生成未来或过去的情节。结果表明,EFT技能仅在一部分ASD儿童中受损,且该亚组在叙事生成任务上的表现明显比具有高EFT技能的ASD参与者和发育正常的参与者更差。本文讨论了这些发现的实际意义和理论意义。
