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)

There is a growing literature in philosophy dealing with the phenomenon of inner speech, that is, the activity of speaking to oneself in one’s mind. This paper highlights a feature of inner speech which has not yet been noticed in this literature: that there is something distinctive that it is like to make a sincere assertion in inner speech. The paper then traces out two implications of this observation. The first relates to the question of how we should characterise inner (...) speech; the second relates to the question of how inner speech may play a role in self-attributions of belief. (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.

This introduction presents a state of the art of philosophical research on cognitive phenomenology and its relation to the nature of conscious thinking more generally. We firstly introduce the question of cognitive phenomenology, the motivation for the debate, and situate the discussion within the fields of philosophy, cognitive psychology and consciousness studies. Secondly, we review the main research on the question, which we argue has so far situated the cognitive phenomenology debate around the following topics and arguments: phenomenal contrast, epistemic (...) arguments and challenges, introspection, ontology and temporal character, intentionality, inner speech, agency, holistic perspective, categorical perception, value, and phenomenological description. Thirdly, we suggest future developments by pointing to four questions that can be explored in relation to the cognitive phenomenology discussion: the self and self-awareness, attention, emotions and general the...

The well-known distinction between access consciousness and phenomenal consciousness has moved away from the conceptual domain into the empirical one, and the debate now is focused on whether the neural mechanisms of cognitive access are constitutive of the neural correlate of phenomenal consciousness. In this paper, I want to analyze the consequences that a negative reply to this question has for the cognitive phenomenology thesis – roughly the claim that there is a “proprietary” phenomenology of thoughts. If the mechanisms responsible (...) for cognitive access can be disentangled from the mechanisms that give rise to phenomenology in the case of perception and emotion, then the same disentanglement is to be expected in the case of thoughts. This, in turn, presents, as I argue, a challenge to the cognitive phenomenology thesis: either there are thoughts with cognitive phenomenology we lack cognitive access to or there are good reasons to doubt that there is such a thing as cognitive phenomenology. I discuss a... (shrink)

Do we experience our thoughts and thinking, or are they subpersonal factors that functionally determine our experience without themselves being experienced? And if we do experience them, do they have a certain qualitative feel to them like pain or color sensations? Within philosophy of mind, these questions are seminal and have led to an ongoing debate over ‘cognitive phenomenology.’ Although both proponents and opponents of the existence and relevance of cognitive phenomenology have presented intriguing arguments, to this day the debate (...) does not yield a conclusive, encompassing, and convincing answer pertaining to the question of whether thinking does or can have an experiential character.

On a widely held view, episodes of inner speech provide at least one way in which we become conscious of our thoughts. However, it can be argued, on the one hand, that consciousness of thoughts in virtue of inner speech presupposes interpretation of the simulated speech. On the other hand, the need for such self-interpretation seems to clash with distinctive first-personal characteristics that we would normally ascribe to consciousness of one’s own thoughts: a special reliability; a lack of conscious ambiguity (...) and incomprehensibility; and a sense of causal agency. I try to resolve this puzzle by proposing an account for the requisite self-interpretation of inner speech in terms of Bayesian probabilistic inference. Drawing on “perceptual loop” accounts of speech control, I argue that such interpretive probabilistic inferences are used for the control of inner speech, and that as a consequence of this function, they are biased toward the correct interpretations. I conclude by showing how this model can explain the first-personal characteristics of consciousness of one’s own thoughts. In the case of the sense of causal agency, the resulting explanation yields novel accounts for “audible thoughts” and thought insertion. (shrink)

This paper assesses two different approaches to inner speech that can be found in the literature. One of them regards inner speech as a vehicle of conscious thought. The other holds that inner speech is better characterised as an activity derived from social uses of its outer counterpart. In this paper I focus on the explanatory power of each approach to account for the control of attention and behaviour in the context of executive tasks. I will argue that the vehicle (...) view cannot capture some central cases of inner speech in executive tasks because they cannot be described as cases of bringing thought into consciousness. Then I will offer a revised version of the activity view and I will apply it to some examples so as to show that it is better posited to account for them. I end by considering two objections to the activity view and a possible way to address them. (shrink)

This paper explores the relation of thought and the stream of consciousness in the light of an ontological argument raised against cognitive phenomenology views. I argue that the ontological argument relies on a notion of ‘processive character’ that does not stand up to scrutiny and therefore it is insufficient for the argument to go through. I then analyse two more views on what ‘processive character’ means and argue that the process-part account best captures the intuition behind the argument. Following this (...) view, I reconstruct the ontological argument and argue that it succeeds in establishing that some mental episodes like judging, understanding and occurrent states of thought do not enter into the stream but fails to exclude episodes like entertaining. Contrary to what it might seem, this conclusion fits well with cognitive phenomenology views, given that, as I show, there is a way for non-processive mental episodes to be fundamentally related to processive ones, such that they cannot be excl..

Recent advances in philosophical thinking about consciousness, such as cognitive phenomenology and mereological analysis, provide a framework that facilitates using computational models to explore issues surrounding the nature of consciousness. Here we suggest that, in particular, studying the computational mechanisms of working memory and its cognitive control is highly likely to identify computational correlates of consciousness and thereby lead to a deeper understanding of the nature of consciousness. We describe our recent computational models of human working memory and propose that (...) three computational correlates of consciousness follow from the results of this work: itinerant attractor sequences, top-down gating, and very fast weight changes. Our current investigation is focused on evaluating whether these three correlates are sufficient to create more complex working memory models that encompass compositionality and basic causal inference. We conclude that computational models of working memory are likely to be a fruitful approach to advancing our understanding of consciousness in general and in determining the long-term potential for development of an artificial consciousness specifically.
