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. (shrink)

Individuals with Autism spectrum disorders (ASD) have difficulties in the recollection of past experiences (Episodic Memory). Accumulating evidence suggests that they might have also difficulties in the ability to imagine potential future scenarios (Episodic Future Thinking, EFT) and in narrative generation skills. This investigation aimed to determine 1) whether impairments of EFT can be identified in a large cohort of children with high functioning ASD using a task with minimal narrative demands; and 2) if such impairments are related to the (...) ability to generate a narrative's scenario. 77 children with high-functioning ASD and 77 children with typical development were recruited for the study. The two groups were balanced for age, level of formal education, and IQ. EFT was assessed by administering a task with minimal narrative demands, whereas narrative generation skills were assessed with three tasks requiring children to generate past, middle or future episodes in a narrative discourse. With respect to control participants, a subgroup of children with ASD had impaired EFT skills and also showed significant impairments in the ability to generate adequate narratives. On the contrary, participants with spared EFT had normal performance on the narrative generation task. Interestingly, EFT skills predicted narrative generation abilities in both groups. The results of this study support the hypothesis that EFT may be impaired in some but not all children with ASD and of a relation between difficulties with EFT and impairments in the process of narrative generation. The assessment of EFT should employ tasks that do not require narrative production, as children with impaired EFT may also have reduced narrative skills. (shrink)

In this paper we propose a narrative account for the origin of language. Such a proposal is based on two assumptions. The first is conceptual and concerns the idea that the distinctive feature of human language (what sets it apart from other forms of animal communication) has to be traced to its inherently narrative character. The second assumption is methodological and connected to the idea that the study of language origin is closely related to the analysis of the cognitive systems (...) at the base of narrative. Research on narrative abilities of subjects with Autism Spectrum Disorder has shown that storytelling requires the capability to link events causally connected to one another, and especially events which are remote from one another on the temporal axis of a story. Based on this research, we hypothesize that an important cognitive device involved in narrative is Mental Time Travel (MTT), that is, the system that allows humans to project themselves into the past and future. We show that such a system is present (to a greater or lesser extent) even in non-human animals. By virtue of this, we argue that MTT is independent of language and that it may be considered a cognitive precursor for the origin of language. Specifically, we propose that MTT allowed our ancestors to develop a form of pantomimic communication that might be considered as the foundation of the narrative origin of language. (shrink)

The current investigation assessed linguistic and narrative abilities in a cohort of children with Autism Spectrum Disorder (ASD). The linguistic assessment was performed with both traditional tests and a multilevel procedure for discourse analysis. The results showed difficulties at different stages of message planning, organization, and microlinguistic processing (i.e., lexical selection and grammatical processing). Their macrolinguistic impairments were likely related to more general difficulties in the prelinguistic conceptual phase of message planning and mental model generation. Such weaknesses included a difficulty (...) in the non-verbal conceptualization of the story and the generation of an internal representation of the addressee’s mental model. (shrink)
