What do the relationships observed in the occurrence of various limb, facial, and speech apraxias following left hemisphere damage mean for Corballis's theory? What does the right hemisphere's role in nonpropositional and automatic speech production tell us about the coevolution of right hand preference and speech; how could the possibility that the right hemisphere may be “dominant” for some aspects of speech be accommodated by his theory?

When we hear another person laugh or scream, can we tell the kind of situation they are in – for example, whether they are playing or fighting? Nonverbal expressions are theorised to vary systematically across behavioural contexts. Perceivers might be sensitive to these putative systematic mappings and thereby correctly infer contexts from others’ vocalisations. Here, in two pre-registered experiments, we test the prediction that listeners can accurately deduce production contexts (e.g. being tickled, discovering threat) from spontaneous nonverbal vocalisations, like sighs (...) and grunts. In Experiment 1, listeners (total n = 3120) matched 200 nonverbal vocalisations to one of 10 contexts using yes/no response options. Using signal detection analysis, we show that listeners were accurate at matching vocalisations to nine of the contexts. In Experiment 2, listeners (n = 337) categorised the production contexts by selecting from 10 response options in a forced-choice task. By analysing unbiased hit rates, we show that participants categorised all 10 contexts at better-than-chance levels. Together, these results demonstrate that perceivers can infer contexts from nonverbal vocalisations at rates that exceed that of random selection, suggesting that listeners are sensitive to systematic mappings between acoustic structures in vocalisations and behavioural contexts.

This article has a few goals. The first goal is to discover the development of Semitic pointing systems such as Babylonian Hebrew (both simple and complex), Tiberian Hebrew, Palestinian Hebrew, Samaritan Hebrew, Syriac (both Western [Jacobite] and Eastern [Nestorian]) and Arabic. The second goal is to propose the possible development because of the interaction between those languages in the past. In this article, the comparative method will be used as the methodology. A general observation of these signs and a proposition (...) regarding the possible development amongst those languages will be presented. CONTRIBUTION: This article traces the synchronic and diachronic development of Semitic languages' vocalisation systems and proposes a possible development between them. (shrink)

Sauter raises interesting points about expressive vocalisations, such as laughing, crying, gasping, etcetera. This reply discusses an expanded research agenda incorporating these. Riemer’s commentary is based on his opposition to nonreferentialist approaches to meaning. My reply seeks to clarify the natural semantic metalanguage (NSM) position on the conceptual status of semantic primes, while urging researchers to consider independently the merits of reductive paraphrase as a heuristic and a corrective to terminological Anglocentrism.

Infants can see someone pointing to one of two buckets and infer that the toy they are seeking is hidden inside. Great apes do not succeed in this task, but, surprisingly, domestic dogs do. However, whether children and dogs understand these communicative acts in the same way is not yet known. To test this possibility, an experimenter did not point, look, or extend any part of her body towards either bucket, but instead lifted and shook one via a centrally pulled (...) rope. She did this either intentionally or accidentally, and did or did not address her act to the subject using ostensive cues. Young 2-year-old children but not dogs understood the experimenter’s act in intentional conditions. While ostensive pulling of the rope made no difference to children’s success, it actually hindered dogs’ performance. We conclude that while human children may be capable of inferring communicative intent from a wide variety actions, so long as these actions are performed intentionally, dogs are likely to be less flexible in this respect. Their understanding of communicative intention may be more dependent upon bodily markers of communicative intent, including gaze, orientation, extended limbs, and vocalisations. This may be because humans have come under selective pressure to develop skills for communicating with absent interlocutors – where bodily co-presence is not possible. (shrink)

Implantable brain-computer interfaces are being developed to restore speech capacity for those who are unable to speak. Patients with locked-in syndrome or amyotrophic lateral sclerosis could be able to use covert speech – vividly imagining saying something without actual vocalisation – to trigger neural controlled systems capable of synthesising speech. User control has been identified as particularly pressing for this type of BCI. The incorporation of machine learning and statistical language models into the decoding process introduces a contribution to (...) the output that is beyond the user’s control. Whilst this type of ‘shared control’ of BCI action is not unique to speech BCIs, the automated shaping of what a user ‘says’ has a particularly acute ethical dimension, which may differ from parallel concerns surrounding automation in movement BCIs. This paper provides an analysis of the control afforded to the user of a speech BCI of the sort under development, as well as the relationships between accuracy, control, and the user’s ownership of the speech produced. Through comparing speech BCIs with BCIs for movement, we argue that, whilst goal selection is the more significant locus of control for the user of a movement BCI, control over process will be more significant for the user of the speech BCI. The design of the speech BCI may therefore have to trade off some possible efficiency gains afforded by automation in order to preserve sufficient guidance control necessary for users to express themselves in ways they prefer. We consider the implications for the speech BCI user’s responsibility for produced outputs and their ownership of token outputs. We argue that these are distinct assessments. Ownership of synthetic speech concerns whether the content of the output sufficiently represents the user, rather than their morally relevant, causal role in producing that output. (shrink)

The first brief description is given of a project aimed at searching for the neural correlates of consciousness through computer simulation. The underlying model is based on the known circuitry of the mammalian nervous system, the neuronal groups of which are approximated as binary composite units. The simulated nervous system includes just two senses - hearing and touch - and it drives a set of muscles that serve vocalisation, feeding and bladder control. These functions were chosen because of their (...) relevance to the earliest stages of human life, and the simulation has been given the name CyberChild. The system's pain receptors respond to a sufficiently low milk level in the stomach, if there is simultaneously a low level of blood sugar, and also to a full bladder and an unchanged diaper. It is believed that it may be possible to infer the presence of consciousness in the simulation through observations of CyberChild's behaviour, and from the monitoring of its ability to ontogenetically acquire novel reflexes. The author has suggested that this ability is the crucial evolutionary advantage of possessing consciousness. The project is still in its very early stages, and although no suggestion of consciousness has yet emerged, there appears to be no fundamental reason why consciousness could not ultimately develop and be observed.

This commentary supports MacNeilage's dismissal of an evolutionary development from sign language to spoken language but presents evidence of a feature in sign language (echo phonology) that links iconic signs to abstract vocal syllables. These data provide an insight into possible mechanism by which iconic manual gestures accompanied by vocalisation could have provided a route for the evolution of spoken language with its characteristically arbitrary form–meaning relationship.

Music is at the centre of what it means to be human – it is the sounds of human bodies and minds moving in creative, story-making ways. We argue that music comes from the way in which knowing bodies (Merleau-Ponty) prospectively explore the environment using habitual 'patterns of action' which we have identified as our innate ‘communicative musicality’. To support our argument, we present short case studies of infant interactions using micro analyses of video and audio recordings to show the (...) timings and shapes of intersubjective vocalisations and body movements of adult and child while they improvise shared narratives of meaning. Following a survey of the history of discoveries of infant abilities, we propose that the gestural narrative structures of voice and body seen as infants communicate with loving caregivers are the building blocks of what become particular cultural instances of the art of music, and of dance, theatre and other temporal arts. Children enter into a musical culture where their innate communicative musicality can be encouraged and strengthened through sensitive, respectful, playful, culturally informed teaching in companionship. The central importance of our abilities for music as part of what sustains our well-being is supported by evidence that communicative musicality strengthens emotions of social resilience to aid recovery from mental stress and illness. Drawing on the experience of the first author as a counsellor, we argue that the strength of one person’s communicative musicality can support the vitality of another’s through the application of skilful techniques that encourage an intimate, supportive, therapeutic, spirited companionship. Turning to brain science, we focus on hemispheric differences and the affective neuroscience of Jaak Panksepp. We emphasise that the psychobiological purpose of our innate musicality grows from the integrated rhythms of energy in the brain for prospective, sensation-seeking affective guidance of vitality of movement. We conclude with a Coda that recalls the philosophy of the Scottish Enlightenment, which built on the work of Heraclitus and Spinoza. This view places the shared experience of sensations of living – our communicative musicality – as inspiration for rules of logic formulated in symbols of language. (shrink)

For Deleuze, the creation and conveyance of meaning requires not a strict fidelity to an original idea, message or image but rather its deformation. The forces causing such disfigurations operate in gesture, vocalisation and text, with one level sometimes disrupting the others. Among them, gesture plays an especially important role, given Deleuze’s attention to bodily experience. He locates it in theatre, painting and cinema, particularly in the works of Carmelo Bene, Francis Bacon and Jerry Lewis. In these cases, instead (...) of conveying a recognisable message, a deformative gesture sends a shock wave that scrambles normal meaning assignments and codings. Yet, although gesture is a main channel for these communication disruptive forces, their origin may lie elsewhere, namely, in a ‘pick-up’ of influences resulting from an inter-affective encounter between heterogeneous bodies.

Gestural and pantomimic accounts of language origins propose that language did not develop directly from ape vocalisations, but rather that its emergence was preceded by an intervening stage of bodily-visual communication, during which our ancestors communicated with their hands, arms, and the entire body. Gestural and pantomimic scenarios are again becoming popular in language evolution research, but this line of thought has a long and interesting history that gained special prominence in the Enlightenment, often considered the golden age of glottogony. (...) We highlight several themes key to this line of reflection, such as the idea of innate communication that consists of visual bodily signs and non-linguistic vocalisations; the division of labour between these two semiotic resources ; or the developmental trajectory of this bi-modal system of communication determined by its transmission through generations of users and the intervention of social factors. We confront these ideas with problems discussed in current language evolution research, focusing on polysemioticity, sign function, conventionality and modality transition. (shrink)

The jaw movements of speech are most probably derived from jaw movements associated with vocalisation. Cyclicity does not argue strongly for derivation from a cyclic pattern, because it arises readily in any system with feedback control. The appearance of regular repetition as a part of ritualisation of a display may have been important.

The Qur’an has been transmitted as both a written text and an oral recital. This has led to the development of a reading tradition that permits numerous different vocalisations to be made upon the basic skeletal text of the established ʿUthmānī codex. Ibn al-Jazarī chose ten early readers whom he felt were most representative of this tradition and whose readings are treated as canonical up until this day. One of these, the Kufan linguist al-Kisāʾī has been characterised in the literature (...) as more focused on the grammar of the Qur’an than his reader peers. This article explores al-Kisāʾī’s process of ikhtiyār when deciding between various possible readings. The sample for analysis consists of Kisāʾī’s tafarrudāt, the approximately fifty cases in which his reading differs from the other nine readers. By comparing his reading with the comments of early scholars of Qur’anic linguistics, especially his near-contemporary al-Farrāʾ, it is possible to construct a typology of the suspected principal reasons for al-Kisāʾī’s tafarrudāt. Not only are many of these based on grammatical preferences, but they demonstrate a significant degree of consistency. Furthermore, analysis of a cluster of readings with implications for the interpretation of the sharīʿa provides evidence for a subtle exegetical dimension to al-Kisāʾī’s work as a reader-grammarian.

Human right-handedness does not originate in vocalisation as such but in selection pressures for structuring complex sequences of digital signals internally, as if in a vacuum. Cautious receivers cannot automatically accept signals in this way. Biological displays are subjected to contextual scrutiny on a signal-by-signal basis – a task requiring coordination of both hemispheres. In order to explain left cerebral dominance in human manual and vocal signalling, we must therefore ask why it became adaptive for receivers to abandon caution, (...) processing zero-cost signals rapidly and on trust.

Nicole Loraux guettait toujours avec une joie d'enfant les premiers frémissements du printemps, la lumière qui verdit et se trémousse, les chatons qui pointent leurs nez jaunes, les oiseaux qui préludent à leur vocalise. Elle s'est éclipsée un jour de sa saison préférée, sans déploiements officiels, entourée seulement de tous ceux qui l'avait aimée et ils étaient très nombreux. Mais le 12 avril, au Père Lachaise, le printemps était en retard, la lumière grise, les arbres encore effeuil...

The two main theories of food-associated calls in animals propose functions either in cooperative recruitment or competitive spacing. However, not all social animals produce food calls and it is largely unclear under what circumstances this call type evolves. Sooty mangabeys do not have food calls, but they frequently produce grunts during foraging, their most common vocalisation. We found that grunt rates were significantly higher when subjects were foraging in the group’s periphery and with small audiences, in line with the (...) cooperative recruitment hypothesis. In a subsequent field experiment we presented highly desired food items and found that discovering individuals called, unless harassed by competitors, but that the calls never attracted others, confirming that the grunts do not convey any information referential to food. Our data thus suggest that the evolution of cooperative food calling is a two-step process, starting with increased motivation to vocalise in the feeding context, followed by the evolution of acoustic variants derived from context-general contact calls. This evolutionary transition may only occur in species that feed on clumped, high-quality resources where social feeding is competitive, a condition not met in sooty mangabeys. (shrink)

La traduction arabo-latine attribuee a Guillaume de Luna du commentaire moyen d'Averroes sur la Logica vetus a fait l'objet en 1996 d'un premier volume: curieusement peut-etre, il proposait l'edition du texte de la troisieme uvre concernee, le Peri Hermeneias ou De interpretatione. Le present volume poursuit l'edition dudit commentaire dans la meme traduction arabo-latine et porte, non sur la premiere uvre de la trilogie: l'Isagoge, mais sur la deuxieme: les Categories ou Predicaments. A peine impliquee dans des citations d'auteurs, l'oeuvre (...) n'est plus connue que par six manuscrits; s' y ajoutent douze editions des XVe et XVIe siecles. La presente edition ressemble a la precedente du commentaire du Peri Hermeneias au moins sous quatre rapports: 1. une comparaison systematique de la version latine medievale du commentaire d'Averroes avec la version hebraique correspondante a ete exclue, ces deux versions ne pouvant etre qu'independantes l'une de l'autre; 2. dans l'apparat comparatif de la version latine avec l'original arabe, les mots arabes sont imprimes en arabe, puis retraduits en latin dans la langue meme du traducteur, sur base d'une etude systematique de la terminologie utilisee dans la traduction; 3. les lexiques sur lesquels s'appuie cette etude de la terminologie, rendent compte d'a peu pres toutes les equivalences arabo-latines etablies par le traducteur, et non, parmi celles-ci, d'une categorie particuliere ne reprenant, par exemple, que les concepts philosophiques; 4. dans les lexiques, les mots arabes sont transcrits en caracteres latins: certaines verifications sont ainsi accessibles aux lecteurs non arabisants; quant aux arabisants, la vocalisation qu'implique la transcription leur signale comment, en fonction de l'interpretation supposee avoir ete celle du traducteur medieval, le referent arabe a de nouveau ete relu et compris.

Interactions of fathers and their children with autism1 The aim of the present study was to compare the activity of fathers and their children with autism with those of children with Down syndrome, and normally developing children during the father-child interaction. Participants were 14 children with autism and their fathers, 15 children with Down syndrome and their fathers, and 16 normally developing children and their fathers. The age of subjects was between 3.0 and 6.0 years old. The study consisted of (...) one 15-minute free-play session in the father-child diad, taking place in the experiment room. Differences between the groups of fathers were found in terms of three variables under analysis: frequency of looking at the child, physical contact with the child and suggesting play. Children with autism brought objects to their fathers or pointed out objects and directed their fathers' attention by vocalising less frequently than children with Down syndrome and normally developing children. Moreover, children with autism exhibited the fewest vocalisations combined with looking at the father and exhibited many more behaviours involving running and moving about the room than normally developing children. Self-stimulating behaviours were the most frequent in children with autism, with no differences in that respect found between children with Down syndrome and normally developing children. The analysis of fathers' behaviour demonstrates that fathers of children with developmental disorders focus on observing their children and attempt to keep close contact with them to a larger extent than fathers of normally developing children. The pattern of differences in the activity of fathers of children with autism and children with Down syndrome does not paint a clear picture. In general, fathers from both groups actively sought to maintain contact with their children. Differences in the activity during play between children with autism and the other subjects in the study are consistent with the clinical features of autism. (shrink)

The work defines the sigh as a type of breath expressing or communicating specific physical or mental internal states. To investigate the meanings of the sigh, the paper presents analyses of written and oral corpora, finding out that it may express different emotions like boredom or frustration, but also positive meanings like self-encouragement; then it focuses on the use of sighs in political debates. Finally a perception study shows participants’ agreement on the meanings of sighs in terms of valence and (...) arousal. These results lay the bases for future studies to set a clearer distinction between sighs and other vocalisations as well as other effects on its meaning caused by the combination with other body signals like rolling eyes or shaking head.

This article presents the first comprehensive study of Syriac rhetoric in late antiquity. It builds on existing scholarship on the Syrians’ engagement with Graeco-Roman paideia and Christian rhetoric, but it also goes further in that it draws attention to the Syrians’ participation in Near Eastern rhetorical traditions (mainly transmitted through Aramaic) and in the rhetoric of the Hebrew Bible, which was translated into Syriac without Greek intermediaries. At the same time, this article demonstrates that Syriac rhetoric flourished in distinctive and (...) original ways: It developed its own literary genres (with a strong predilection for poetry and a sensibility for gendered voices), performative settings (including the liturgy and the school), and thematic domains (notably Scriptural exegesis and religious controversy). It is especially remarkable that an elaborate “meta-rhetorical” reflection flourished in Syriac, as it first emerged in the work by Antony of Tagrit in the ninth century and in the broader context of late antique and Byzantine Aristotelianism. This comprehensive survey and its conceptual systematisation are designed to facilitate further research on Syriac rhetoric both during late antiquity and in later centuries, when the Syrians’ interaction with Arabic rhetoric came to play an increasingly influential role.Syriac words are given in a simplified transcription. For consonants, the standard system in use for Semitic languages is followed; spirantisation of b g k p t is marked by v gh kh f th respectively. East Syrian vocalisation is generally adopted unless the words are quoted from a West Syrian author; vowel length is not marked, with the exception of a/ā and e/ē in Eastern Syriac. (shrink)

In the present paper we address the old question of respiratory planning in speech production. We recast the problem in terms of speakers’ communicative goals and propose that speakers try to minimise respiratory effort in line with H&H theory. We analyze respiratory cycles coinciding with no speech (i.e. silence), short verbal feedback expressions (SFE’s) as well as longer vocalisations in terms of parameters of the respiratory cycle and find little evidence for respiratory planning in feedback production. We also investigate timing (...) of speech and SFEs in the exhalation and contrast it with nods. We find that while speech is strongly tied to the exhalation onset, SFEs are distributed much more uniformly throughout the exhalation and are often produced on residual air. Given that nods, which do not have any respiratory constraints, tend to be more frequent towards the end of an exhalation, we propose a mechanism whereby respiratory patterns are determined by the trade-off between speakers’ communicative goals and respiratory constraints.

In 2018 and 2019 Cancer Research UK launched a controversial advertising campaign to inform the British public of obesity being a preventable cause of cancer. On each occasion the advertisements used were emotive and provoked frustration among the British public which was widely vocalised on social media. As well serving to educate the public of this association, the advertisements also had the secondary effect of acting as health promotion through social marketing, a form of advertising designed to influence behavioural changes. (...) As CRUK delivered a public health message through its campaign, the advertisements should be held according to the ethical principles which underpin healthcare in the UK. This article evaluates whether the advertisements used by CRUK in 2018 and 2019 fulfilled the ethical principles of beneficence, autonomy, non-maleficence and justice. It is found that while providing an important message, the oversimplification of obesity as being the result of personal decisions ignored the complex aetiology and served to stigmatise the target demographic, potentially disengaging them from the message. Additionally, posting cancer as the consequence of obesity invokes feelings of fear due to its connotations of suffering and premature death. Based on available evidence, the use of fear in social marketing does not create sustained behavioural change. This essay recommends that CRUK discontinue its use of such strategies in its future social marketing endeavours. (shrink)

Language’s intentional nature has been highlighted as a crucial feature distinguishing it from other communication systems. Specifically, language is often thought to depend on highly structured intentional action and mutual mindreading by a communicator and recipient. Whilst similar abilities in animals can shed light on the evolution of intentionality, they remain challenging to detect unambiguously. We revisit animal intentional communication and suggest that progress in identifying analogous capacities has been complicated by (i) the assumption that intentional (that is, voluntary) production (...) of communicative acts requires mental-state attribution, and (ii) variation in approaches investigating communication across sensory modalities. To move forward, we argue that a framework fusing research across modalities and species is required. We structure intentional communication into a series of requirements, each of which can be operationalised, investigated empirically, and must be met for purposive, intentionally communicative acts to be demonstrated. Our unified approach helps elucidate the distribution of animal intentional communication and subsequently serves to clarify what is meant by attributions of intentional communication in animals and humans.
