Inner Speech

Inner speech vs. anendophasia: Questions of information, serendipity, and the mental realm’s connection with nature.

Inner speech travels under many aliases: the inner voice, verbal thought, thinking in words, internal verbalization, “talking in your head,” the “little voice in the head,” and so on. It is both a familiar element of first-person experience and a psychological phenomenon whose complex cognitive components and distributed neural bases are increasingly well understood. There is evidence that inner speech plays a variety of cognitive roles, from enabling abstract thought, to supporting metacognition, memory, and executive function. One active area of (...) controversy concerns the relation of inner speech to auditory verbal hallucinations in schizophrenia, with a common proposal being that sufferers of AVH misidentify their own inner speech as being generated by someone else. Recently, researchers have used artificial intelligence to translate the neural and neuromuscular signatures of inner speech into corresponding outer speech signals, laying the groundwork for a variety of new applications and interventions.

Inner speech is commonly understood as the conscious experience of a voice within the mind. One recurrent theme in the scientific literature is that the phenomenon involves a representation of overt speech, for example, a representation of phonetic properties that result from a copy of speech instructions that were ultimately suppressed. I propose a larger picture that involves some embodied objects and their misperception. I call it “the Body Error Theory,” or BET for short. BET is a form of illusionism, (...) but the particular version I favor is a cross-modal illusion. Newly described here, my hypothesis is that the experience of inner speech arises from a mix of interoception and audition. Specifically, there is the detection of slight but well-confirmed activities in the speech musculature that occur during inner speech, which helps to transform representations of normal but quiet nonverbal sounds that inevitably occur during inner speech, from breathing to background noise, into a mistaken perception of inner speech. Simply put, activities in the speech musculature mix with sounds to create the appearance of speech sounds, which thus explains the “voice within the mind.” I also show how BET’s cross-modal system fits with standard information processing accounts for speech monitoring and how it accommodates the central insights of leading theories of inner speech. In addition, I show how BET is supported by data from experience-sampling surveys and how it can be empirically tested against its rivals. (shrink)

Sometimes, thinking a thought and saying something to oneself are the same event. Call this the ‘thinking-as-speaking’ thesis. It stands in opposition to the idea that we think something first, and then say it. One way to argue for the thesis is to show that the content of a token thought cannot be fully represented by a token mental state before the production of the utterance which expresses it. I make an argument for that claim based on speech act theory. (...) Many inner speech utterances are inner speech acts; as such they are individuated by an amalgam of semantic content and illocutionary force, which only come together with the performance of the speech act. Call the performance of a speech act its meaning and call its meaning its content. Since a token thought is individuated by its content it follows that the content of the speech act is not represented by any token mental state before the speech act is performed. Metaphysically, a thought, when it is an inner speech act, is not an object of any kind, but an action – the action of performing the speech act. I illustrate my argument with the action of deciding something. (shrink)

In November 2022, OpenAI released ChatGPT, an incredibly sophisticated chatbot. Its capability is astonishing: as well as conversing with human interlocutors, it can answer questions about history, explain almost anything you might think to ask it, and write poetry. This level of achievement has provoked interest in questions about whether a chatbot might have something similar to human intelligence or even consciousness. Given that the function of a chatbot is to process linguistic input and produce linguistic output, we consider the (...) question whether a sophisticated chatbot might have inner speech. That is: Might it talk to itself, internally? We explored this via a conversation with ‘Playground’, a chatbot which is very similar to ChatGPT but more flexible in certain respects. We asked it questions which, plausibly, can only be answered if one first produces some inner speech. Here, we present our findings and discuss their philosophical significance. (shrink)

Background: Many people with aphasia and people without brain injury talk to themselves in their heads, i.e., have “inner speech.” Inner speech may be more preserved compared with spoken speech for some people with aphasia and may serve a variety of functions (e.g., emotion regulation), which motivates us to provide a high-fidelity characterization of it. Researchers have used multiple methods to measure this internal phenomenon in the past, which we combine here for the first time in a single study. -/- (...) Aims: We compare performance between individuals with and without aphasia on inner speech tasks that assess inner speech “inthe- moment” to general subjective impressions of inner speech to tease apart the relationship of aphasia severity to inner speech. Methods and Procedures: Twenty people with mild-moderate aphasia and twenty neurotypical controls completed several inner speech tasks, including objective silent rhyme judgements (picture, written, and auditory), subjective reports of inner speech during naming, and subjective rating scales about inner speech experience more generally. -/- Outcomes and Results: In-the-moment inner speech during silent rhyming tasks was associated with aphasia severity only for picture and written rhyming but not auditory rhyming. In-the-moment inner speech reports during silent naming were not associated with aphasia severity, nor were the subjective ratings about general inner speech experience. Individuals with and without aphasia demonstrated a variety of subjective general inner speech experiences, demonstrating heterogeneity of this phenomenon more broadly. -/- Conclusions: Methods of measuring inner speech complement each other and speak to different facets of the inner speech phenomenon, and clinicians and researchers must carefully choose the method(s) that will provide the information about inner speech that they desire.

Illusionists about consciousness boldly argue that phenomenal consciousness does not fundamentally exist — it only seems to exist. For them, the impression of having a private inner life of conscious qualia is nothing more than a cognitive error, a conjuring trick put on by a purely physical brain. Some phenomenal realists have accused illusionism of being a byproduct of modern Western scientism and overzealous naturalism. However, Jay Garfield has endorsed illusionism by explicitly drawing support from the classical Yogācāra Buddhist philosopher (...) Vasubandhu. In this paper, I assess the degree to which Garfield’s illusionist interpretation accurately captures the views of Vasubandhu and his commentator Sthiramati in their extant Sanskrit works. As it turns out, Vasubandhu and Sthiramati converge with contemporary illusionists in taking an unconscious causal basis of cognitive/linguistic processes to be responsible for generating the illusion of representational states with apparently phenomenal contents. Within their constitutive understanding of the mind as the “imagination of what is non-existent” (abhūtaparikalpa), I raise possible candidates for what might seem to be real instances of phenomenality — mental appearances (pratibhāsa), affective sensory experience (vedanā), and “intrinsic luminosity” (prakṛtiprabhāsvara) — and consider possible responses on behalf of an illusionist interpreter. I conclude that Vasubandhu and Sthiramati really do appear to be strong illusionists about phenomenal consciousness, particularly if phenomenal states are assumed to be essentially representational.

The notion of a mental interior has been derided as a Cartesian relic, the 'ghost in the machine' (Ryle, 1963). Yet there is a mental interior — indeed, there are two — only not where we tend to look. When a toddler talks to herself before sleep, she often plays the part of a parent toward herself, mitigating the dread of separation. She thus creates a pretend space between herself-as-parent and herself-as-child. Growing up, she plays others toward herself as well. (...) She and her simulated interlocutors are experienced by her as an expanded self with an inside, namely the place of inner speech. This pretend space is the first non-bodily interior. The second develops as a consequence. The simulated others diminish the dependence on actual others, who therefore cease to appear in their former importance. One yearns for them as they were, but the yearning is blocked — and banished from awareness — by dread of reverting to the earlier dependence. This second interior is the space between the unconscious self and the full kind of other for whom it yearns. The yearning enters conscious life indirectly and unthreateningly, for example in the fictive frame of art and in the relational frame of conversation. (shrink)

The sensory constraint on conscious thought says that if a thought is phenomenally conscious, its phenomenal properties must be reducible to some sensory phenomenal character. I argue that the burgeoning psychological literature on aphantasia, an impoverishment in the ability to generate mental imagery, provides a counterexample to the sensory constraint. The best explanation of aphantasics’ introspective reports, neuroimaging, and task performance is that some aphantasics have conscious thoughts without sensory mental imagery. This argument against the sensory constraint supports the existence (...) of a non-sensory phenomenology of thought. Moreover, this argument can be extended to show that this non-sensory phenomenology determines a thought content. Finally, it can potentially diagnose the disagreement over cognitive phenomenology in the philosophy of mind, as such disagreement may turn on interpersonal variation in mental imagery. (shrink)

Here I will develop a naturalistic account of epistemic reflection and its significance for epistemology. I will first argue that thought, as opposed to mere information processing, requires a capacity for cognitive self-regulation. After discussing the basic capacities necessary for cognitive self-regulation of any kind, I will consider qualitatively different kinds of thought that can emerge when the basic capacities enable the creature to interiorize a form of social cooperation. First, I will discuss second-personal cooperation and the kind of thought (...) that emerges from its interiorization. Then, I will discuss third-personal cooperation and the kind of thought that emerges from its interiorization. We will see that epistemic reflection is the interiorized version of interpersonal argumentation, which is the epistemic component of third-personal cooperation. In developing this account, I will draw heavily on the work of Michael Tomasello and other cognitive scientists advocating the “social intentionality hypothesis”. However, I will show how work done in the defeasible reasoning tradition can provide us with a deeper explanation of some claims made by advocates of the social intentionality hypothesis. Additionally, we will see that work done on social intentionality can help us better understand the significance of knowledge and justification as understood by the defeasible reasoning tradition. We will see that the social intentionality hypothesis and the defeasible reasoning tradition are mutually illuminating. By drawing equally on both, I will provide a novel account of the foundations of knowledge. (shrink)

Many theorists assume that a request is sincere if the speaker wants the addressee to perform the act requested. I argue that this assumption predicts an implausible mismatch between sincere assertions and sincere directives and needs to be revised. I present an alternative view, according to which directive utterances can only be sincere if they are self-directed. Other-directed directives, however, can be genuine or fake, depending on whether the speaker wants the addressee to perform the act in question. Finally, I (...) argue that this new perspective opens the door to a satisfying theory of authentic expression, for both assertive and directive utterances. Authenticity consists in the combination of genuine and sincere speech, for example, in the case of assertion, when speakers assert something which they both believe (sincerity) and want the addressee to believe (genuineness).

I argue that introspection recruits the same mental mechanism as that which is required for the production of ordinary speech acts. In introspection, in effect, we intentionally tell ourselves that we are in some mental state, aiming thereby to produce belief about that state in ourselves. On one popular view of speech acts, however, this is precisely what speakers do when speaking to others. On this basis, I argue that every bias discovered by social epistemology applies to introspection and other (...) forms of self-directed representation. If so, it becomes unclear in what sense social epistemology is social. (shrink)

Is inner speech an intentional action, something we do, or a reaction, something that happens to us? This paper will argue that it can be both, (although not at the same time). Some inner speech utterances are reactive: they are spontaneous, they require no effort, and we are not in control of their occurring. These inner speech utterances fail to meet the traditional criteria for qualifying as intentional actions. But some inner speech ut- terances are intentional actions, performed deliberately, effortfully (...) and with as much control as any other intentional action. When we deliberate, for example, inner speech utterances are the basic actions by which we bring about the non-basic action of deliberating. (shrink)

Two connected questions that arise for anyone interested in inner speech are whether we tell ourselves something that we have already thought; and, if so, why we would tell ourselves something that we have already thought. In this contribution I focus on the first question, which is about the nature and the production of inner speech. While it is usually assumed that the content of what we tell ourselves is exactly the content of a non-linguistic thought, I argue that there (...) can be a lot of transformation in the process of converting a thought into words. Thus, the content of what we tell ourselves, being intrinsically linguistic, is different from the content of the thought our speech transmits. Fleshing out this kind of approach implies dealing with complicated questions which we lack enough knowledge about: the nature of non-linguistic thinking, and how speech (inner and overt) is produced; i.e. how the speaker goes from format a (format of thought) to format b (language). I show that these are pressing issues for any other position, but also suggest ways in which we could tackle such complicated issues. (shrink)

Several theories propose that one of the core functions of inner speech (IS) is to support subjects in the completion of cognitively effortful tasks, especially those involving executive functions (EF). In this paper we focus on two populations who notoriously encounter difficulties in performing EF tasks, namely, people diagnosed with schizophrenia who experience auditory verbal hallucinations (Sz-AVH) and people within the Autism Spectrum Conditions (ASC). We focus on these two populations because they represent two different ways in which IS can (...) fail to help in EF tasks, which can be illustrative for other mental conditions. First, we review the main components of EF (Section 1). Then we explain the functions that IS is taken to perform in the domain of EF (Section 2) and review the evidence concerning problems about EF in the two populations of our study: Sz-AVH (Section 3) and ASC (Section 4). After this we further detail our account about what a properly functioning IS can do for both populations and how different IS profiles may impact EF performance: in the case of Sz-AVH, the uncontrolled and intrusive character of IS negatively affects EF performance, whereas in ASC, EF is not sufficiently supported by IS, given the tendency in this population to present a diminished use of IS (Section 5). We finally briefly discuss Attention Deficit/Hyperactivity Disorder (ADHD) and Developmental Language Disorders (DLD). (shrink)

A widespread view in philosophy claims that inner speech is closely tied to human metacognitive capacities. This so-called format view of inner speech considers that talking to oneself allows humans to gain access to their own mental states by forming metarepresentation states through the rehearsal of inner utterances (section 2). The aim of this paper is to present two problems to this view (section 3) and offer an alternative view to the connection between inner speech and metacognition (section 4). According (...) to this alternative, inner speech (meta)cognitive functions derivate from the set of commitments we mobilize in our communicative exchanges. After presenting this commitment-based approach, I address two possible objections (section 5). (shrink)

To some it is a shallow platitude that inner speech always has an auditory-phonological component. To others, it is an empirical hypothesis with accumulating support. To yet others it is a false dogma. In this chapter, I defend the claim that inner speech always has an auditory-phonological component, confining the claim to adults with ordinary speech and hearing. It is one thing, I emphasize, to assert that inner speech often, or even typically, has an auditory-phonological component—quite another to propose that (...) it always does. When forced to argue for the stronger point, we stand to make a number of interesting discoveries about inner speech itself, and about our means for discriminating it from other psycholinguistic phenomena. Establishing the stronger conclusion also provides new leverage on debates concerning how we should conceive of, diagnose, and explain auditory verbal hallucinations and “inserted thoughts” in schizophrenia.

This is the introductory chapter to the anthology: Inner Speech: New Voices, to be published in fall 2018 by OUP. It gives an overview of current debates in philosophy, psychology, and neuroscience concerning inner speech, and situates the chapters of the volume with respect to those debates.

This study examines the relation of language use to a person’s ability to perform categorization tasks and to assess their own abilities in those categorization tasks. A silent rhyming task was used to confirm that a group of people with post-stroke aphasia (PWA) had corresponding covert language production (or “inner speech”) impairments. The performance of the PWA was then compared to that of age- and education-matched healthy controls on three kinds of categorization tasks and on metacognitive self-assessments of their performance (...) on those tasks. The PWA showed no deficits in their ability to categorize objects for any of the three trial types (visual, thematic, and categorial). However, on the categorial trials, their metacognitive assessments of whether they had categorized correctly were less reliable than those of the control group. The categorial trials were distinguished from the others by the fact that the categorization could not be based on some immediately perceptible feature or on the objects’ being found together in a type of scenario or setting. This result offers preliminary evidence for a link between covert language use and a specific form of metacognition. (shrink)

In this paper we address the question of what determines the content of our conscious episodes of thinking, considering recent claims that phenomenal character individuates thought contents. We present one prominent way for defenders of phenomenal intentionality to develop that view and then examine ‘sensory inner speech views’, which provide an alternative way of accounting for thought-content determinacy. We argue that such views fare well with inner speech thinking but have problems accounting for unsymbolized thinking. Within this dialectic, we present (...) an account of the nature of unsymbolized thinking that accords with and can be seen as a continuation of the activity of inner speech, while offering a way of explaining thought-content determinacy in terms of linguistic structures and representations. (shrink)

Many philosophers and psychologists have sought to explain experiences of auditory verbal hallucinations and “inserted thoughts” in schizophrenia in terms of a failure on the part of patients to appropriately monitor their own inner speech. These self-monitoring accounts have recently been challenged by some who argue that AVHs are better explained in terms of the spontaneous activation of auditory-verbal representations. This paper defends two kinds of self-monitoring approach against the spontaneous activation account. The defense requires first making some important clarifications (...) concerning what is at issue in the dispute between the two forms of theory. A popular but problematic self-monitoring theory is then contrasted with two more plausible conceptions of what the relevant self-monitoring deficits involve. The first appeals to deficits in the neural mechanisms that normally filter or attenuate sensory signals that are the result of one’s own actions. The second, less familiar, form of self-monitoring approach draws an important analogy between Wernicke’s aphasia and AVHs in schizophrenia. This style of self-monitoring theory pursues possible connections among AVHs, inserted thoughts, and the disorganized speech characteristic formal thought disorder. (shrink)

Using the method of Descriptive Experience Sampling, some subjects report experiences of thinking that do not involve words or any other symbols [Hurlburt, R. T., and C. L. Heavey. 2006. Exploring Inner Experience. Amsterdam: John Benjamins; Hurlburt, R. T., and S. A. Akhter. 2008. “Unsymbolized Thinking.” Consciousness and Cognition 17 : 1364–1374]. Even though the possibility of this unsymbolized thinking has consequences for the debate on the phenomenological status of cognitive states, the phenomenon is still insufficiently examined. This paper analyzes (...) the main properties of unsymbolized thinking and advances an explanation of its origin. According to our analysis, unsymbolized thoughts appear as propositional states, that is, they are experienced as compositional conceptual phenomena, with semantic and syntactic features analogous to those of the contents of utterances. Based on this characterization, we hypothesize that UT is continuous with the activity of inner speech, in particular, it i... (shrink)

Despite the ubiquity of inner speech in our mental lives, methods for objectively assessing inner speech capacities remain underdeveloped. The most common means of assessing inner speech is to present participants with tasks requiring them to silently judge whether two words rhyme. We developed a version of this task to assess the inner speech of a population of patients with aphasia and corresponding language production deficits. As expected, patients’ performance on the silent rhyming task was severely impaired relative to controls. (...) More surprisingly, however, patients’ performance on this task did not correlate with their performance on a variety of other standard tests of overt language abilities. In particular, patients who were generally unimpaired in their abilities to overtly name objects during confrontation naming tasks, and who could reliably judge when two words spoken to them rhymed, were still severely impaired (relative to controls) at completing the silent rhyme task. This seems to suggest that inner speech was more severely impaired in these patients than outer speech. However, these results should also cause us to critically reflect on the relation between inner speech and silent rhyme judgments more generally. (shrink)

In this paper we introduce two issues relevantly related to the cognitive phenomenology debate, which, to our minds, have not been yet properly addressed: the relation between access and phenomenal consciousness in cognition and the relation between conscious thought and inner speech. In the first case, we ask for an explanation of how we have access to thought contents, and in the second case, an explanation of why is inner speech so pervasive in our conscious thinking. We discuss the prospects (...) of explanation for both sides of the debate and argue that cognitive phenomenology defenders are in an overall advantageous position. We also propose an account of inner speech that differs from other influential explanations in some interesting respects. (shrink)

Many theorists claim that inner speech is importantly linked to human metacognition (thinking about one's own thinking). However, their proposals all rely upon unworkable conceptions of the content and structure of inner speech episodes. The core problem is that they require inner speech episodes to have both auditory-phonological contents and propositional/semantic content. Difficulties for the views emerge when we look closely at how such contents might be integrated into one or more states or processes. The result is that, if inner (...) speech is especially valuable to metacognition, we do not currently understand why it is. The article concludes with two positive proposals for understanding the content and structure of inner speech episodes, which should serve as constraints on future accounts of the metacognitive value of inner speech.

Recently, many philosophers and psychologists have claimed that the explanation that grounds both passivity phenomena in the cognitive domain and passivity phenomena that occur with respect to overt actions is, along broad lines, the same. Furthermore, they claim that the best account we have of such phenomena in both scenarios is the “comparator” account. However, there are reasons to doubt whether the comparator model can be exported from the realm of overt actions to the cognitive domain in general. There is (...) a lingering worry concerning such explanations of thought insertion: the "What is compared to what?" problem. Here I examine two ways to tackle this problem. First: thought insertion consists of the misattribution of strings of inner speech which are not attenuated (thought insertion is thus another name for auditory verbal hallucinations). Second: thought insertion is misattributed inner speech which exhibits the same phenomenological characteristics as normal inner speech. After explaining the types of problem that each of these potential solutions faces, I conclude with a set of open questions that the comparator theorist has to tackle. (shrink)

We respond to Moseley and Wilkinson's defense of inner speech models of AVH.

The present review of literature surveys two main issues related to self-referential processes: (1) Where in the brain are these processes located, and do they correlate with brain areas uniquely specialized in self-processing? (2) What are the empirical and theoretical links between inner speech and self-awareness? Although initial neuroimaging attempts tended to favor a right hemispheric view of selfawareness, more recent work shows that the brain areas which support self-related processes are located in both hemispheres and are not uniquely activated (...) during self-reflective tasks. Furthermore, self-awareness at least partially relies on internal speech. An activation of Broca's area (which is known to sustain inner speech) is observed in a significant number of brain-imaging studies of self-reflection. Loss of inner speech following brain damage produces self-awareness deficits. Inner speech most likely can internally reproduce social mechanisms leading to self-awareness. Also, the process of self-reflection can be seen as being a problem-solving task, and self-talk as being a cognitive tool the individual uses to effectively work on the task. It is noted that although a large body of knowledge already exists on self-awareness, little is known about individual differences in dispositional self-focus and types of self-attention (e.g., rumination vs. self-reflection).

We very often discover ourselves engaged in inner speech. It seems that this kind of silent, private, speech fulfils some role in our cognition, most probably related to conscious thinking. Yet, the study of inner speech has been neglected by philosophy and psychology alike for many years. However, things seem to have changed in the last two decades. Here we review some of the most influential accounts about the phenomenology and the functions of inner speech, as well as the methodological (...) problems that affect its study. (shrink)

Abstract: Introspection reveals that one is frequently conscious of some form of inner speech, which may appear either in a condensed or expanded form. It has been claimed that this speech reflects the way in which language is involved in conscious thought, fulfilling a number of cognitive functions. We criticize three theories that address this issue: Bermúdez’s view of language as a generator of second-order thoughts, Prinz’s development of Jackendoff’s intermediate-level theory of consciousness, and Carruthers’s theory of inner speech as (...) a rehearsal of action-schemata. We contend they have problems to account for those cases in which inner speech is fragmentary, and for the difference with those instances in which it appears as more sentence-like. In addition, we present verbal overshadowing as a phenomenon that neither of them can easily explain. Finally, we propose an account in which inner speech is fundamentally silent outer speech and argue that it is more explanatory than the alternatives. (shrink)

Invited paper for the Oxford Companion to Consciousness, in press.

Inner speech represents the activity of talking to oneself in silence. It can be assessed with questionnaires, sampling methods, and electromyographic recordings of articulatory movements. Inner speech has been linked to thought processes and self-awareness. Private speech (speech-for-self emitted aloud by children) serves an important self-regulatory function. The frequency of private speech follows an inverted-U relation with age, peaking at 3-4 years of age and disappearing at age 10. Social and inner speech share a common neurological basis: Broca’s area. Dysfunctional (...) self-talk is known to mediate many pathological conditions; negative selfverbalizations have a more significant debilitating impact than positive ones. (shrink)

To test the hypothesis of a participation of inner speech in self-referential activity we reviewed 59 studies measuring brain activity during processing of self-information in the following self-domains: agency, self-recognition, emotions, personality traits, autobiographical memory, preference judgments, and REST. The left inferior frontal gyrus (LIFG) has been shown to sustain inner speech use. We calculated the percentage of studies reporting LIFG activity for each self-dimension. 55.9% of all studies reviewed identified LIFG (and presumably inner speech) activity during self-awareness tasks. Furthermore, (...) the LIFG was more frequently recruited during conceptual tasks (e.g., emotions, traits) than during perceptual tasks (e.g., agency, self-recognition). This supports the view of a relative involvement of inner speech in self-reflective processes. Crown Copyright © 2007 Published by Elsevier Inc. All rights reserved. (shrink)

Little is known with regard to the precise cognitive tools the self uses in acquiring and processing information about itself. In this article, we underline the possibility that inner speech might just represent one such cognitive process. Duval and Wicklund’s theory of self-awareness and the selfconsciousness, and self-knowledge body of work that was inspired by it are reviewed, and the suggestion is put forward that inner speech parallels the state of self-awareness, is more frequently used among highly self-conscious persons, and (...) represents an effective, if not indispensable, tool involved in the formation of the self-concept. The possibility is also raised that the extent to which one uses inner speech could partially explain individual differences in self-consciousness and self-knowledge. A selective review of the private and inner speech literature is presented, and some possible ways of testing the hypothesis by using pre-existing techniques are proposed in the hope of stimulating empirical investigations. Some implications are outlined in conclusion. (shrink)
