Action perception and recognition are core abilities fundamental for human social interaction. A parieto-frontal network (the mirror neuron system) matches visually presented biological motion information onto observers' motor representations. This process of matching the actions of others onto our own sensorimotor repertoire is thought to be important for action recognition, providing a non-mediated “motor perception” based on a bidirectional flow of information along the mirror parieto-frontal circuits. State-of-the-art machine learning strategies for hand action identification have shown better performances when sensorimotor (...) data, as opposed to visual information only, are available during learning. As speech is a particular type of action (with acoustic targets), it is expected to activate a mirror neuron mechanism. Indeed, in speech perception, motor centers have been shown to be causally involved in the discrimination of speech sounds. In this paper, we review recent neurophysiological and machine learning-based studies showing (a) the specific contribution of the motor system to speech perception and (b) that automatic phone recognition is significantly improved when motor data are used during training of classifiers (as opposed to learning from purely auditory data).

The effects of lexical context on phonological processing are pervasive and there have been indications that such effects may be modulated by attention. However, attentional modulation in speech processing is neither well documented nor well understood. Experiment 1 demonstrated attentional modulation of lexical facilitation of speech sound recognition when task and critical stimuli were identical across attention conditions. We propose modulation of lexical activation as a neurophysiologically plausible computational mechanism that can account for this type of modulation. Contrary (...) to the claims of critics, this mechanism can account for attentional modulation without violating the principle of interactive processing. Simulations of the interactive TRACE model extended to include two different ways of modulating lexical activation showed that each can account for attentional modulation of lexical feedback effects. Experiment 2 tested conflicting predictions from the two implementations and provided evidence that is consistent with bias input as the mechanism of attentional control of lexical activation.

Right-ear advantage refers to the observation that when two different speech stimuli are simultaneously presented to both ears, listeners report stimuli more correctly from the right ear than the left. It is assumed to result from prominent projection along the auditory pathways to the contralateral hemisphere and the dominance of the left auditory cortex for the perception of speech elements. Our study aimed to investigate the role of attention in the right-ear advantage. We recorded magnetoencephalography data while participants (...) listened to pairs of Japanese two-syllable words. The amplitudes of the stimuli were modulated at 35 Hz in one ear and 45 Hz in the other. Such frequency-tagging allowed the selective quantification of left and right auditory cortex responses to left and right ear stimuli. Behavioral tests confirmed the right-ear advantage, with higher accuracy for stimuli presented to the right ear than to the left. The amplitude of the auditory steady-state response was larger when attending to the stimuli compared to passive listening. We detected a correlation between the attention-related increase in the amplitude of the auditory steady-state response and the laterality index of behavioral accuracy. The right-ear advantage in the free-response dichotic listening was also found in neural activities in the left auditory cortex, suggesting that it was related to the allocation of attention to both ears.

Inferences made from endocasts of fossil skulls cannot provide information on the function of particular neocortical areas or the subcortical pathways to prefrontal cortex that form part of the neural substrate for speech, syntax, and certain aspects of cognition. The neural bases of syntax cannot be disassociated from “communication.” Manual motor control was probably a preadaptive factor in the evolution of humansyntactic ability, but neurophysiological data on living humans show that speech motor control and syntax are more closely (...) linked. The evolution of fully modern speech occurred fairly recently; thoughHomo habilismay have had some degree of speech and syntactic ability, it was not fully modern. Stone tools are uncertain indices of language or cognition. (shrink)

This review article summarizes various functions of the dorsolateral prefrontal cortex that are related to language processing. To this end, its connectivity with the left-dominant perisylvian language network was considered, as well as its interaction with other functional networks that, directly or indirectly, contribute to language processing. Language-related functions of the DLPFC comprise various aspects of pragmatic processing such as discourse management, integration of prosody, interpretation of nonliteral meanings, inference making, ambiguity resolution, and error repair. Neurophysiologically, the DLPFC seems to (...) be a key region for implementing functional connectivity between the language network and other functional networks, including cortico-cortical as well as subcortical circuits. Considering clinical aspects, damage to the DLPFC causes psychiatric communication deficits rather than typical aphasic language syndromes. Although the number of well-controlled studies on DLPFC language functions is still limited, the DLPFC might be an important target region for the treatment of pragmatic language disorders. (shrink)

This commentary questions the proposed resemblance between the auditory mechanisms of localization and those of the sensory registration of speech sounds. Comparative evidence, which would show that the neurophysiology of localization is adequate to the task of categorizing consonants, does not exist. In addition, Sussman et al. do not offer sensory or perceptual evidence to confirm the presence in humans of processes promoting phoneme categorization that are analogous to the neurophysiology of localization. Furthermore, the computational simulation of (...) the linear model of second formant variation is not a plausible sensory mechanism for perceiving speech sounds. (shrink)

Lip reading is the ability to partially understand speech by looking at the speaker's lips. It improves the intelligibility of speech in noise when audio-visual perception is compared with audio-only perception. A recent set of experiments showed that seeing the speaker's lips also enhances sensitivity to acoustic information, decreasing the auditory detection threshold of speech embedded in noise [J. Acoust. Soc. Am. 109 (2001) 2272; J. Acoust. Soc. Am. 108 (2000) 1197]. However, detection is different from comprehension, (...) and it remains to be seen whether improved sensitivity also results in an intelligibility gain in audio-visual speech perception. In this work, we use an original paradigm to show that seeing the speaker's lips enables the listener to hear better and hence to understand better. The audio-visual stimuli used here could not be differentiated by lip reading per se since they contained exactly the same lip gesture matched with different compatible speech sounds. Nevertheless, the noise-masked stimuli were more intelligible in the audio-visual condition than in the audio-only condition due to the contribution of visual information to the extraction of acoustic cues. Replacing the lip gesture by a non-speech visual input with exactly the same time course, providing the same temporal cues for extraction, removed the intelligibility benefit. This early contribution to audio-visual speech identification is discussed in relationships with recent neurophysiological data on audio-visual perception. (shrink)

During the last decades, the enigmatic field of volition has been the object of quantitative brain mapping studies. In this essay, emphasis will be given to brain mapping observations during overt or imagined willed acts in conscious normal individuals. The findings suggest that such acts are ‘formulated’ in the frontal/prefrontal cortex as neuronal programs for future motor, behavioural, verbal, or cognitive acts. During imagined movements or speech, brain mapping reveals important prefrontal activations which contrast to perirolandic activations during overt (...) willed acts. In psychiatric disorders with symptoms of a ‘sick will', like in schizophrenia, affective disorders, and organic dementia, reductions of the resting prefrontal activity have been recorded. The relationship between will and prefrontal activity is compatible with the view that frontal/prefrontal parts of the cortex are involved in the serial temporal programming of motor behaviour, speech, and cognition. In addition, there are unconscious mechanisms participating in volition. Electrophysiological evidence presented by Libet supports this view. (shrink)

Why does symbolic communication in humans develop primarily in an oral medium, and how do theories of language origin explain this? Non-human primates, despite their ability to learn and use symbolic signs, do not develop symbols as in oral language. This partly owes to the lack of a direct cortico-motoneuron control of vocalizations in these species compared to humans. Yet such modality-related factors that can impinge on the rise of symbolic language are interpreted differently in two types of evolutionary storylines. (...) 1) Some theories posit that symbolic language originated in a gestural modality, as in “sign languages”. However, this overlooks work on emerging sign and spoken language showing that gestures and speech shape signs differently. 2) In modality-dependent theories, some emphasize the role of iconic sounds, though these lack the efficiency of arbitrary symbols. Other theorists suggest that ontogenesis serves to identify human-specific mechanisms underlying an evolutionary shift from pitch varying to orally-modulated vocalizations (babble). This shift creates numerous oral features that can support efficient symbolic associations. We illustrate this principle using a sound-picture association task with 40 learners who hear words in an unfamiliar language (Mandarin) with and without a filtering of oral features. Symbolic associations arise more rapidly and accurately for sounds containing oral features compared to sounds bearing only pitch features, an effect also reported in experiments with infants. The results imply that, beyond a competence to learn and use symbols, the rise of symbolic language rests on the types of signs that a modality of expression affords. (shrink)

This volume represents a comprehensive overview of the neuropsychology of emotion and the neural mechanisms underlying emotional processing. It draws on recent studies utilizing behavioral paradigms with normal subjects, the brain lesion approach, clinical evaluations of patients with neurological and psychiatric disorders, and neuroimaging techniques. The book opens with an introduction summarizing each chapter and pointing to directions for future research. The first section is on history, the neuroanatomy and neurophysiology of emotion, and techniques that have been widely used (...) to examine emotional processing- neuropsychological assessment and neuroimaging. Theoretical perspectives on emotion are offered next, including psychological, social-cognitive, neurobiological, and neuropsychological models. A set of chapters on the neural substrates of emotion deals with a spectrum of emotional conditions: elation and mania, sadness and depression, anxiety and stress, anger and impulsivity, and apathy and flat affect. The book concludes with clinical implications, including a description of emotional deficits in neurological and psychiatric disorders. Highlighted in this section is an overview of rehabilitative treatments and brain interventions for emotional processing deficits. This authoritative volume will be an important resource and text for neuropsychologists, clinical psychologists, speech-language pathologists, neuroscientists, psychiatrists, neurologists, rehabilitation specialists, and their students and trainees.

This paper offers a systematic classification and characterization of speech acts and their norms. Recently, the normative approach has been applied to various speech acts, most notably to constatives. I start by showing how the work on the norms of assertion has influenced various approaches to the norms of other speech acts. I focus on the fact that various norms of assertion have different extensions, i.e., they denote different clusters of illocutions as belonging to an assertion. I (...) argue that this has consequences for theorising about norms of other speech acts and generates certain arbitrary divisions. In the central part, I analyse two groups of speech acts. Firstly, ordinary speech acts, like predictions or retractions. Secondly, I indicate how the normative view can be extended to so-called ancillary speech acts, like presuppositions or implicatures. I end with a discussion of possible extensions of the normative approach, focusing on the debate on lying. (shrink)

Predictions during language comprehension are currently discussed from many points of view. One area where predictive processing may play a particular role concerns poetic language that is regularized by meter and rhyme, thus allowing strong predictions regarding the timing and stress of individual syllables. While there is growing evidence that these prosodic regularities influence language processing, less is known about the potential influence of prosodic preferences on neurophysiological processes. To this end, the present electroencephalogram study examined whether the predictability of (...) strong and weak syllables within metered speech would differ as a function of meter. Strong, i.e., accented positions within a foot should be more predictable than weak, i.e., unaccented positions. Our focus was on disyllabic pseudowords that solely differed between trochaic and iambic structure, with trochees providing the preferred foot in German. Methodologically, we focused on the omission Mismatch Negativity that is elicited when an anticipated auditory stimulus is omitted. The resulting electrophysiological brain response is particularly interesting because its elicitation does not depend on a physical stimulus. Omissions in deviant position of a passive oddball paradigm occurred at either first- or second-syllable position of the aforementioned pseudowords, resulting in a 2-by-2 design with the factors foot type and omission position. Analyses focused on the mean oMMN amplitude and latency differences across the four conditions. The result pattern was characterized by an interaction of the effects of foot type and omission position for both amplitudes and latencies. In first position, omissions resulted in larger and earlier oMMNs for trochees than for iambs. In second position, omissions resulted in larger oMMNs for iambs than for trochees, but the oMMN latency did not differ. The results suggest that omissions, particularly in initial position, are modulated by a trochaic preference in German. The preferred strong-weak pattern may have strengthened the prosodic prediction, especially for matching, trochaic stimuli, such that the violation of this prediction led to an earlier and stronger prediction error. Altogether, predictive processing seems to play a particular role in metered speech, especially if the meter is based on the preferred foot type. (shrink)

Philosophy & Social Criticism, Volume 48, Issue 4, Page 515-529, May 2022. Much of the recent literature on freedom of speech has focused on the arguments for and against the regulation of certain kinds of speech.

In this paper we argue, first, that none of these justifications meet all four intuitive desiderata for an adequate theory of free speech. We go on to sketch an original relational view of free speech, one which grounds its value in the recognition that speakers grant each other when engaging in speech practices, and its limits in the republican ideal of non-dominated co-exercisable liberty. We briefly illustrate the relational approach’s implications for the debate on hate speech regulation and for the response to fake news. (shrink)

Semantics traditionally focuses on linguistic meaning. In recent years, the Super Linguistics movement has tried to broaden the scope of inquiry in various directions, including an extension of semantics to talk about the meaning of pictures. There are close similarities between the interpretation of language and of pictures. Most fundamentally, pictures, like utterances, can be either true or false of a given state of affairs, and hence both express propositions (Zimmermann, 2016; Greenberg, 2013; Abusch, 2015). Moreover, sequences of pictures, like (...) sequences of utterances, can be used to tell stories. Wordless picture books, comics, and film are cases in point. In this paper I pick up the project of providing a dynamic semantic account of pictorial story-telling, started by Abusch (2012) and continued by Abusch & Rooth (2017); Maier & Bimpikou (2019); Fernando (2020). More specifically, I propose here a semantics of speech and thought bubbles by adding event reference to PicDRT. To get there I first review the projection-based semantics for pictures (section 1), noting the fundamental distinction between symbolic and iconic meaning that makes speech bubbles especially interesting (section 2). I then review the dynamic PicDRT framework for pictorial narratives (section 3), add events (section 4), and propose an account of speech bubbles as quotational event modification (section 5). I end with a brief look at other conventional, symbolic enrichments in comics (section 6). (shrink)

Foundations of Speech Act Theoryoffers a timely, thorough and, above all, compelling examination of the complexities of illocutionary acts, performatives, and their phenomenological basis. Savas Tsohatzidis has collected an impressive range of international scholars on the subject. Clearly demonstrating the relevance of speech act theory to semantic theory, the collection further interrogates the inability of pragmatic theories of illocution to properly locate such speech acts within the logic of phenomenology and intersubjectivity.

In authoritarian states, the discourse on freedom of speech, conducted by those opposed to non-democratic governments, focuses on the core aspects of this freedom: on a right to criticize the government, a right to advocate theories arid ideologies contrary to government-imposed orthodoxy, a right to demand institutional reforms, changes in politics, resignation of the incompetent and the corrupt from positions of authority. The claims for freedom of speech focus on those exercises of freedom that are most fundamental and (...) most beneficial to citizens - and which are denied to them by the government. But in a by-and large democratic polity, where these fundamental benefits of freedom of speech are generally enjoyed by the citizens, the public and scholarly discourse on freedom of speech hovers about the peripheries of that freedom; the focus is on its outer boundaries rather than at the central territory of freedom of speech. Those borderline cases, in which people who are otherwise genuinely committed to the core aspects of freedom of speech may sincerely disagree, include pornography, racist hate speech and religious bigoted expressions, defamation of politicians and of private persons, contempt of court, incitement to violence, disclosure of military or commercial secrets, advertising of merchandise such as alcohol or cigarettes or of services and entertainment such as gambling and prostitution.

With increasing influence of illiberalism, freedom should not be considered or interpreted lightly. Post-truth contexts provide grounds for alt-right movements to capture and pervert notions of freedom of speech, making universities battlefields of politicised emotions and expressions. In societies facing these pressures around the world, academic freedom has never been challenged as much as it is today. As Peters and colleagues note, conceptualisations of ‘facts’ and ‘evidences’ are politically, socially, and epistemically reconstructed in post-truth contexts. At the same time, (...) with intelligence commodified, reified or marginalised, freedom of speech and of mobility can entail fights for entitlements, or escapes from local responsibilities. The decline and corruptions of democratic free speech and academic freedom, or the absence of forces to defend them, are thus serious challenges. These challenges grow as the competition of ideas, sometimes under the rubric of academic freedom, often implies the power struggle and questioning of statuses in the so-called ‘marketplace of ideas’. Competition as a value invoked in some conceptualisations of freedom, becomes more important than human dignity, which was originally supposed to expand and strengthen under democratic conceptions of freedom in higher education. What had been happening to freedoms, of speech, teaching, and learning, across different subject positions and cultures of higher education, remains largely underexplored, as alt-right movements, neoliberalism and illiberalism, and post-truthism values and orientations expand.

Psychology can be based on plans, internally held images of achievement that organize the stimulus-response links of traditional psychology. The hierarchical structure of plans must be produced, held, assigned priorities, and monitored. Consciousness is the operation of the plan-executing mechanism, enabling behavior to be driven by plans rather than immediate environmental contingencies. The mechanism unpacks a single internally held idea into a series of actions. New in this paper is the proposal that language uses this mechanism for communication, unpacking an (...) idea into a series of articulatory acts. Language comprehension uses the plan-monitoring mechanism to pack a series of linguistic events into an idea. Recursive processing results from monitoring one's own speech. Neurophysiologically, the planning mechanism is identified with higher-order motor control. (shrink)

Are there moral facts? According to moral nihilism, the answer is no. Some moral nihilists are moral error theorists, who think that moral judgements purport to refer to moral facts, but since there are no moral facts, moral judgements are uniformly false or untrue. Terence Cuneo has recently raised an original and potentially very serious objection to moral error theory. According to Cuneo’s ‘normative theory of speech’, normative facts, some of which are moral facts, are crucially involved in explanations (...) of how it is that we are able to perform illocutionary speech acts, such as asserting, promising, and commanding. Many versions of moral error theory reject not only moral facts, but also normative facts of the kind Cuneo takes to be among the prerequisites of our abilities to perform illocutionary speech acts. If Cuneo’s argument is successful, then, moral error theory has the unsettling implication that we do not speak, and possibly that we cannot speak. I shall argue, however, that the argument ultimately fails, chiefly because its core premise fails to establish that illocutionary speech acts are normative in the first place. (shrink)

This paper adopts Deleuze’s reading of Spinoza’s expressionism and pure semiotics to argue that Spinoza’s Ethics offers an alternative notion of freedom of speech that is based on the potentia of the individual. Its aim is to show how freedom of thought is connected to the problem of individuation that connects our mode of being with our power to speak and think. Rather than treating freedom of speech as an enlightened idea that is in opposition to, for example, (...) religious authority, or the suppression of human rights, this paper argues that freedom of speech should be understood by what Spinoza calls ‘an adequate idea’: an idea that explains the cause of its own production. What is to be considered is: who wants this freedom, in what situation, why, what is at stake? No freedom in itself is ever given. This paper argues for speech as an assembled body that is always in connection with other bodies. It is argued that to understand the power and value of the freedom of speech, we should study the praxis of the utterance as an assembled body, its causal dimensions, and its affective immanent relations with other bodies, and other modes of speaking.

Historical research has recently made it clear that, prior to Austin and Searle, the phenomenologist Adolf Reinach (1884-1917) developed a full-fledged theory of speech acts under the heading of what he called "social acts". He we consider a second instance of a speech act theory avant la lettre, which is to be found in the common sense philosophy of Thomas Reid (1710-1796). Reid’s s work, in contrast to that of Reinach, lacks both a unified approach and the detailed (...) analyses of pertinent examples. But his writings leave no doubt that he is acutely aware of the very problems concerning language structure and use out of which contemporary speech act theory has evolved and that he goes a good way towards solving these problems in the spirit of the modern theory.

"This book on freedom of speech and expression starts with an inter-cultural history of this valued right through the ages and then recalls the benefits for which we rightly value it. But what about speech that frustrates these benefits? Supporters of the benefits of free speech have reason to exercise voluntary self-restraint on speech which frustrates the benefits. They should also cultivate a second remedy: the art, illustrated in chapter 1, and called by Gandhi the art (...) of 'opening ears', by other kinds of speech and conduct. Such voluntary methods are to be preferred to legal constraints. But legal constraint is sometimes necessary. In the 21st century, social media funding based on manipulation of personal speech data requires skilful legislation and enforcement in favour of social media that protect our freedoms"--. (shrink)

That uses of language not only can, but even normally do, have the character of actions was a fact largely unrealised by those engaged in the study of language before the present century, at least in the sense that there was lacking any attempt to come to terms systematically with the action-theoretic peculiarities of language use. Where the action-character of linguistic phenomena was acknowledged, it was normally regarded as a peripheral matter, relating to derivative or nonstandard aspects of language which (...) could afford to be ignored.

Two computer simulations are investigated that model interaction of cultural evolution of language and biological evolution of adaptations to language. Both are agent‐based models in which a population of agents imitates each other using realistic vowels. The agents evolve under selective pressure for good imitation. In one model, the evolution of the vocal tract is modeled; in the other, a cognitive mechanism for perceiving speech accurately is modeled. In both cases, biological adaptations to using and learning speech evolve, (...) even though the system of speech sounds itself changes at a more rapid time scale than biological evolution. However, the fact that the available acoustic space is used maximally (a self‐organized result of cultural evolution) is constant, and therefore biological evolution does have a stable target. This work shows that when cultural and biological traits are continuous, their co‐evolution may lead to cognitive adaptations that are strong enough to detect empirically. (shrink)

I take it that liberal justice recognises special protections against the restriction of speech and expression; this is what I call the Free Speech Principle. I ask if this Principle includes speech acts which might broadly be termed ‘hate speech’, where ‘includes’ is sensitive to the distinction between coverage and protection , and between speech that is regulable and speech that should be regulated . I suggest that ‘hate speech’ is too broad a (...) designation to be usefully analysed as a single category, since it includes many different kinds of speech acts, each of which involves very different kinds of free speech interests, and may cause very different kinds of harm. I therefore propose to disaggregate hate speech into various categories which are analysed in turn. I distinguish four main categories of hate speech, namely (1) targeted vilification, (2) diffuse vilification, (3) organised political advocacy for exclusionary and/or eliminationist policies, and (4) other assertions of fact or value which constitute an adverse judgment on an identifiable racial or religious group. Reviewing these categories in the light of the justifications for the Free Speech Principle, I will argue that category (1) is uncovered by the Principle, categories (2) and (3) are covered but unprotected , and that category (4) is protected speech.

How certain neural mechanisms momentarily endow with the subjective awareness percepts and affects represented elsewhere is more likely to be clarified when structures essential to Mc are identified. The loss of C with bilateral thalmic lesions involving the intralaminar nuclei contrasts with retention of C after large cortical ablations depriving C of specific contents. A role of ILN in the perception of primitive sensations is suggested by their afference of directly ascending pathways. A role for ILN in awareness of cortical (...) activity is suggested by their widespread afference from cortex, a property shared with striatum. A role for ILN in volition is suggested by their heavy projection to striatum. Unlike striatum, ILN also project widely to almost all neocortex, enabling an effect on ideation; this last property is in common with other structures but none of them has the same direct cortical afference. And passage through the reticular nucleus of ILN efferents to cortex could impact the attention-selective action of nRt. It is suggested that the quickest route to a better understanding of C involves more intensive study of ILN. No other structure seems, in the light of our current knowledge, a more likely site for Mc. (shrink)

In the philosophy of liberalism, freedom of speech is one of the fundamental rights of the individual, one that is guaranteed by the constitution of a liberal democratic state. Contemporary Western democracies are based on the political culture in which human rights, including the right to free speech, play an important role. This right, however, can be violated by demagogic propaganda both in totalitarian regimes and in democracies. The propaganda mechanism, reaching into the sphere of community values and (...) concepts, presently operates also through the Internet, in which expressions of anger and hatred are disseminated and can lead to the destruction of democracy. I will argue that, in today’s world, restrictions on the freedom of speech through legal norms are necessary, because the threat comes not only in the form of censorship, but also the manipulation techniques used by politicians in democratic regimes. Advances in modern technology can be of service to dictatorship when the media and the Internet are used for propaganda or surveillance purposes, but they also provide a support to freedom and democracy when they serve as the means of the transmission of reliable information, initiating public discussions. As such, they establish a framework for rational debates and peaceful activities that contribute to the maintenance of the democratic political culture. The basic elements of this culture, i.e. legal rules, pluralist media, and education systems are all necessary for the defence of its core value, namely the freedom of speech. (shrink)
