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.

Growing evidence suggests that theory of mind (ToM) and episodic future thinking (EFT) are closely related at both brain and functional level. This study explored the relationship between ToM and EFT in 96 Italian-speaking children with typical development aged between 8 and 10.11 using a behavioral design. ToM was assessed through an emotional facial expression recognition task. EFT was assessed with a task where participants were required to project themselves forward in time by anticipating future states of the self; this resulted in two scores: a nonverbal measure and a verbal explanation measure. Results showed that the participants’ performance on the task assessing ToM correlated with and predicted the nonverbal measure of the EFT task. These findings are discussed in the light of theories suggesting that each of these abilities is governed by a common system devoted to self-projection.

The present study analyzed the comprehension of visual narrative in a group of twelve children with autism spectrum disorders (ASD). Their performances were compared to a control group of fifteen children with typical development (TD) matched for age, level of formal education, and IQ. Visual narrative comprehension was assessed by administering a task that required children to understand narrative's global coherence by arranging in the correct order the constituent parts of stories presented in pictures. Specifically, the task evaluated children's ability to grasp how single events connected (causally and temporally) each other and how these connections led to the ending of the story. Results showed that children with ASD obtained significantly lower scores than children with TD. These results open to alternative interpretations of narrative impairments often reported in individuals with ASD, which might not be restricted to the linguistic code but stem from a deeper deficit in narrative processing that is independent from the expressive modality.

Several disciplines contribute to the discussion on the origin of language: computer simulation, cognitive psychology, genetics, paleoanthropology, and comparative studies, as some examples. Some disciplines employ sophisticated analysis techniques resulting in empirical evidence inconceivable until a few years ago. However, the huge volume of data available and the heterogeneity of disciplines have had problematic effects on research: each discipline contributing to the study of language is different from another, so the first difficulty is identification of a point of convergence among extremely heterogeneous empirical results. This paper tries to delineate a new theorethical framework for the study of language orings able to synthesize currentempirical results. This new paradigm is based on the embodied tehories of language and mind.

However, this cooperative character is what makes it evolutionarily suspect: under normal circumstances sharing honest information with biologically unrelated individuals and without any obvious costs is not an ESS (evolutionarily stable strategy) and is not expected to evolve. Here we approach this problem in the context of prototypical language use (also evolutionarily), that is face-to-face conversation, a multimodal interaction unfolding in real time that involves a complex interplay between embodied agents in spatial proximity. We focus our review on low-level coordinative processes – examples being proxemic alignment or postural mirroring – to a large degree continuous with what is found in non-human primates. We aim at categorisation and terminological clarification of these processes, which in turn helps us evaluate their role in initiating and maintaining cooperatively oriented communicative interaction. We conclude with suggesting ways in which such low-level coordinative processes might have formed an evolutionary basis for cooperation, with focus on the possible role of TFT (tit-for-tat) and TFT-like strategies.

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.

Impairments of motor representation of actions have been reported as a core component of autism spectrum disorders (ASD). Individuals with ASD have difficulties in a number of functions such as assuming anticipatory postures, imitating body movements, producing and understanding gestures, and recognizing motor intentions. Such cognitive-motor abilities are all involved in pantomime. However, the available evidence on the production and comprehension of pantomime in individuals with ASD is still inconclusive. The current investigation assessed pantomime comprehension in 40 children with high-functioning ASD and 40 children with typical development balanced for age, IQ, level of formal education, and cognitive profile. The participants were asked to watch video recordings of pantomimes representing simple transitive events enacted by actors and match them to the corresponding pictorial representations. Such pantomimes were delivered in two conditions with different levels of information content (i.e., lean or rich). The two groups of children performed similarly on these tasks. Nonetheless, children with ASD who were administered the pantomimes in the lean condition performed worse than participants who were administered the informatively richer pantomimes. The methodological implications for interpretation of previous findings and future studies are discussed.

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.

This brief report is a partial replication of the study by Jackson and Atance (J Dev Disabil 14:40-45, 2008) assessing nonverbal Self-based and Mechanical-based future thinking (FT) in children with Autism Spectrum Disorder (ASD). In a first step, these tasks were administered to 30 children with ASD. The two Self-based tasks were then modified as a verbal component could not be completely ruled out. Consequently, 77 children with ASD and 77 children with typical development received the modified Self-based FT tasks and the Mechanical-based FT tasks. We partially replicated the previous findings. Participants with ASD had impaired FT in both kinds of tasks and both groups performed better on tasks assessing Mechanical-based FT than Self-based FT. These results suggest that impairments of FT in ASD are not limited to Self-Projection.
