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)

In this paper we propose a pragmatic approach to the evolution of language based on analysis of a particular element of human communication: discourse coherence. We show that coherence is essential for effective communication. Through analysis of a collection of neuropsychological and neurolinguistic studies, we maintain that the proper functioning of executive processes responsible for planning and executing actions plays a key role in the construction of coherent discourses. Studies that tested the discursive and conversational abilities of bonobos have showed (...) that apes are unable to construct a flow of discourse governed by coherence, and therefore, apes’ conversational interactions are quite different from those of humans. We then propose that the emergence of coherence in communication occurred after the split between great apes’ and humans’ lines of descendants and that this emergence might have been the result of a specific gradual development in the course of hominin evolution of the executive functions.

Models of discourse and narration elaborated within the classical compositional framework have been characterized as bottom-up models, according to which discourse analysis proceeds incrementally, from phrase and sentence local meaning to discourse global meaning. In this paper we will argue against these models. Assuming as a case study the issue of discourse coherence, we suggest that the assessment of coherence is a top-down process, in which the construction of a situational interpretation at the global meaning level guides local meaning analysis. (...) In support of our hypothesis, we explore the role of executive functions (brain functions involved in planning and organization of goal-oriented behaviors) in coherence’s establishment, discussing the results of several studies on narrative abilities of patients with brain injuries. We suggest that, compared to other models of discourse processing focused on comprehension, our model is a viable candidate for an integrated account of discourse comprehension and production.

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)

The main intent of this paper is to give an account of the relationship between bio-cognition and culture in terms of coevolution, analysing religious beliefs and language evolution as case studies. The established view in cognitive studies is that bio-cognitive systems constitute a constraint for the shaping and the transmission of religious beliefs and linguistic structures. From this point of view, religion and language are by-products or exaptations of processing systems originally selected for other cognitive functions. We criticize such a (...) point of view, showing that it paves the way for the idea that cultural evolution follows a path entirely autonomous and independent from that of biological evolution. Against the by-product and exaptation approaches, our idea is that it is possible to interpret religion and language in terms of coevolution. The concept of coevolution involves a dual path of constitution: one for which biology (cognition) has adaptive effects on culture, the other for which, in turn, forms of culture have adaptive effects on biology (cognition). This dual path of constitution implies that religion and language are (at least in some aspects) forms of biological adaptations. (shrink)

This paper aims to show how clinical pragmatics can fruitfully inform the classical theoretical models proposed by philosophical pragmatics. In the first part of the paper I argue that theories proposed in the domain of philosophical pragmatics, as those elaborated by Austin and Grice, are not plausible from a cognitive point of view and that for this reason they cannot be useful to understand pragmatic deficits. In the second part, I show that Relevance Theory overcomes this limitation, but I also (...) argue that it offers a restricted view of human communication which has to be integrated with a model of language use that takes into account a central pragmatic property: coherence of discourse.

In this paper, we show how the embodied revolution within cognitive sciences has relevant consequences for the topic of language origins. The empirical findings of the embodied approaches, indeed, allow to elaborate a motor theory of language origins according to which human language originated from the gestural communication of our ancestors. Theories that propose that human language emerged from gesture suggest that an important stage in the evolution of human communication was that of pantomime, i.e. a spontaneous bodily mode of (...) expression in which meaning is conveyed through resemblance. Adhering to this idea, we suggest that pantomime can be considered a platform for the emergence of human communication as it is a primordial mode of expression to tell stories without language. Based on that, we maintain that the possibility to explain the advent of language with reference to pantomime represents a way to support a narrative model of language origins. (shrink)

Riassunto: Al centro di questo lavoro è l’analisi di due disturbi acquisiti del linguaggio: l’afasia di Broca e l’afasia di Wernicke. Tradizionalmente, tali disturbi sono stati interpretati come deficit che colpiscono le funzioni legate, rispettivamente, alla produzione articolatoria e alla comprensione del parlato in seguito a lesioni in due specifiche regioni cerebrali: nel caso dell’afasia di Broca, la terza circonvoluzione frontale sinistra; nel caso dell’afasia di Wernicke, la porzione posteriore del giro temporale superiore sinistro. Per tale ragione, queste due regioni (...) cerebrali, a cui ci si riferisce anche nei termini di area di Broca e area di Wernicke, sono state considerate le sedi neuroanatomiche della produzione e comprensione del linguaggio. Questo articolo mostra che, alla luce delle ricerche condotte negli ultimi decenni: non è più possibile sul piano dei deficit linguistici continuare a considerare l’afasia di Broca e l’afasia di Wernicke come disturbi unitari; non è più possibile continuare a sostenere l’esclusiva localizzazione delle funzioni di produzione e comprensione del linguaggio nelle due regioni cerebrali ad esse classicamente associate. Parole chiave: Afasia di Broca; Afasia di Wernicke; Area di Broca; Area di Wernicke; Disturbi del linguaggio; Localizzazione cerebrale; Neuroscienze Broca’s and Wernicke’s Aphasias in the Light of Contemporary Neuroscience: This paper analyzes two acquired language disorders: Broca’s aphasia and Wernicke’s aphasia. It has been commonly suggested that these disorders respectively affect functions related to speech production and language comprehension and they have been understood to result from two specific types of brain lesions: Broca’s aphasia from lesions in the third left frontal convolution; Wernicke’s aphasia from lesions in the posterior section of the left superior temporal gyrus. For this reason, these cerebral regions, also known as Broca’s area and Wernicke’s area, have long been viewed as the neuroanatomical correlates of language production and comprehension. This paper shows that in light of current research: with regard to language disorders, it is no longer possible to conceive of Broca’s and Wernicke's aphasias as unitary disorders; with regard to the cerebral localization of linguistic functions, it no longer possible to suggest that Broca’s and Wernicke’s areas are the only regions involved in speech production and comprehension.

Il volume, in un'ottica cognitiva, affronta il tema delle patologie del linguaggio coniugando la riflessione teorica con le più recenti evidenze empiriche provenienti dalle neuroscienze, dalla neuropsicologia e dalla psicopatologia. Tra i casi presi in esame, ampio spazio è dedicato alla discussione dei deficit comunicativi che caratterizzano patologie quali la sindrome dello spettro autistico, il trauma cranico, la schizofrenia e la demenza di Alzheimer. In casi del genere, i disturbi linguistici e comunicativi chiamano in causa la dimensione pragmatica del linguaggio (...) e dipendono da deficit che coinvolgono in primo luogo la sfera cognitiva e solo in seconda istanza la dimensione specificatamente linguistica. Lo studio dei disturbi pragmatici diventa, così, un modo particolarmente proficuo per indagare una questione più generale di estremo interesse da un punto di vista teorico: i rapporti tra linguaggio e cognizione.

Riassunto: Al centro di questo articolo è l’analisi dei fondamenti neurocognitivi dei deficit macrolinguistici, discorsivo-narrativi nello specifico, osservabili nei pazienti affetti da schizofrenia. Tale analisi è condotta in riferimento alle ricerche svolte negli ultimi decenni nell’ambito della psicolinguistica e delle neuroscienze. I risultati di queste ricerche hanno mostrato che alcuni aspetti dei disturbi macroelaborativi che caratterizzano il profilo linguistico dei pazienti schizofrenici possono essere spiegati chiamando in causa i deficit di tre sistemi cognitivi: teoria della mente, funzioni esecutive, memoria semantica. (...) In questo articolo si sostiene che un tale quadro esplicativo vada integrato attraverso il riferimento a un ulteriore processo cognitivo cruciale per l’elaborazione macrolinguistica: la costruzione di scenari. Tale processo è fondamentale per la comprensione e produzione discorsiva in quanto responsabile della costruzione della rappresentazione globale degli eventi del discorso narrativo. Alla luce di queste considerazioni, in questo lavoro si propone che un ruolo cruciale nella spiegazione di alcuni aspetti dei disturbi macrolinguistici nella schizofrenia sia svolto da una compromissione nel processo di costruzione di scenari mentali e si avanza l’ipotesi che tale compromissione sia determinata, a sua volta, da problematiche che agiscono sul piano del funzionamento delle aree cerebrali preposte alla percezione e all’assemblaggio multimodale delle rappresentazioni sensomotorie. Parole chiave: Abilità macrolinguistiche; Costruzione di scenari; Elaborazione discorsiva: Embodied Cognition; Narrazione; Schizofrenia; Percezione; Modelli mentali The role scenario building in the explanation of macrolinguistic disorders in schizophrenia: This article analyzes the neurocognitive foundations of macrolinguistic deficits, specifically narrative, observable in patients with schizophrenia. This analysis is conducted with reference to the investigations carried out in recent decades in the field of psycholinguistics and neuroscience. The results of these investigations showed that some aspects of macrolinguistic deficits of schizophrenics can be explained in terms of impairments of three cognitive systems: theory of mind, executive functions, and semantic memory. In this article, it is suggested that this explanatory framework has to be integrated with the reference to a further cognitive process: scenarios construction. Such process turns out to be critical for discourse comprehension and production as it is responsible for the building of the global representation of events of a narrative. In the light of these considerations, it is claimed that a crucial role in the explanation of some aspects of macrolinguistic disorders in schizophrenia is played by an impairment in the process of constructing mental scenarios. The hypothesis is that this impairment is, in turn, determined by problems affecting the brain areas responsible for the perception and multimodal assembly of sensorimotor representations.

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)
