Results: We analyzed 1,402 surveys and 15 in-depth interviews. Many (32%) CL participants reported greater difficulty refilling medications and a minority (14%) reported greater difficulty accessing HIV care during the pandemic. Most (99%) Opt4Mamas participants reported no difficulty refilling medications or accessing HIV/pregnancy care. Among the CL participants, older women were less likely (aOR = 0.95, 95% CI: 0.92–0.98) and women with more children were more likely (aOR = 1.13, 95% CI: 1.00–1.28) to report difficulty refilling medications. Only 2% of (...) CL participants reported greater difficulty managing FP and most (95%) reported no change in likelihood of using FP or desire to get pregnant. Qualitative analysis revealed three major themes: (1) adverse organizational/economic implications of the pandemic, (2) increased importance of pregnancy prevention during the pandemic, and (3) fear of contracting COVID-19.

This article presents the first results of a study of the decisions made by health professionals in South Australia concerning the management of death, dying, and euthanasia, and focuses on the findings concerning the attitudes and practices of medical practitioners. Mail-back, self-administered questionnaires were posted in August 1991 to a ten per cent sample of 494 medical practitioners in South Australia randomly selected from the list published by the Medical Board of South Australia. A total response rate of 68 per (...) cent was obtained, 60 per cent of which (298) were usable returns. It was found that forty-seven per cent had received requests from patients to hasten their deaths. Nineteen per cent had taken active steps which had brought about the death of a patient. Sixty-eight per cent thought that guidelines for withholding and withdrawal of treatment should be established. Forty-five per cent were in favour of legalisation of active euthanasia under certain circumstances. (shrink)

The role of membrane receptors is regarded as being to transduce the signal represented by ligand binding from the external cell surface across the membrane into the cell. Signals are subsequently conveyed from the cytoplasm to the nucleus through a combination of second-messenger molecules, kinase/phosphorylation cascades, and transcription factor (TF) translocation to effect changes in gene expression. Mounting evidence suggests that through direct targeting to the nucleus, polypeptide ligands and their receptors may have an important additional signaling role. Ligands such (...) as those of the platelet-derived and fibroblast growth factor classes, as well as cytokines such as interferon-γ and interleukins-1 and -5, have been found to localize in the nucleus through the action of nuclear localization sequences (NLSs). Where tested, these NLSs appear to be essential for full signaling activity and may be responsible for cotranslocating receptors to the nucleus in complexes with their ligands. The implication is that, subsequent to endocytosis at the membrane, particular polypeptide ligands or their receptors, or both, may translocate to the nucleus to participate directly in gene regulation.

This study draws on neo-institutional theory to examine how and why corporate environmental management practices might affect environmental performance. It contributes to the literature by using a large, global data set to investigate the impact of 10 corporate environmental management practices on greenhouse gas emissions or emissions intensity. It focuses on greenhouse gas emissions which pose an existential threat to the people and planet, and the environmental management practices of corporations whose effectiveness has provoked cynicism and claims of “greenwash”. Our (...) results are based on a dynamic, robust and large-scale econometric analysis, which includes tests of association and Granger causation in comparison with earlier research. A key finding, which is of interest not only to the academic literature but also to policymakers and managers, is that environmental performance impacts environmental management practices but not vice versa, supporting the hypothesis that corporations adopt these practices as a symbolic legitimizing device rather than a genuine attempt derived from moral obligation to reduce their greenhouse gases or carbon intensity.

The aim of the study was to develop a new comprehensive reading assessment battery for multi-ethnic and multilingual learners in Malaysia. Using this assessment battery, we examined the reliability, validity, and dimensionality of the factors associated with reading difficulties/disabilities in the Malay language, a highly transparent alphabetic orthography. In order to further evaluate the reading assessment battery, we compared results from the assessment battery with those obtained from the Malaysian national screening instrument. In the study, 866 Grade 1 children from (...) multi-ethnic and multilingual backgrounds from 11 government primary schools participated. The reading assessment battery comprised 13 assessments, namely, reading comprehension, spelling, listening comprehension, letter name knowledge, letter name fluency, rapid automatized naming, word reading accuracy, word reading efficiency, oral reading fluency, expressive vocabulary, receptive vocabulary, elision, and phonological memory. High reliability and validity were found for the assessments. An exploratory factor analysis yielded three main constructs: phonological-decoding, sublexical-fluency, and vocabulary-memory. Phonological-decoding was found to be the most reliable construct that distinguished between at-risk and non-at-risk children. Identifying these underlying factors will be useful for detecting children at-risk for developing reading difficulties in the Malay language. In addition, these results highlight the importance of including a range of reading and reading-related measures for the early diagnosis of reading difficulties in this highly transparent orthography.

This paper contributes to biodiversity and species extinction literature by examining the relationship between corporate accountability in terms of species protection and factors affecting such accountability from forward-thinking companies. We use triangulation of theories, namely deep ecology, legitimacy, and we introduce a new perspective to the stakeholder theory that considers species as a ‘stakeholder’. Using Poisson pseudo-maximum likelihood regression, we examine a sample of 200 Fortune Global companies over 3 years. Our results indicate significant positive relations between ecologically conscious companies (...) that are accountable for the protection of biodiversity and species extinction and external assurance, environmental performance, partnerships with socially responsible organizations and awards for sustainable activities. Our empirical results appear to be robust in controlling for possible endogeneities. Our findings contribute to the discussion on the concern of species loss and habitat destruction in the context of corporate accountability, especially in responding to the sixth mass extinction event and COVID-19 crisis. Our results can also guide the policymakers and stakeholders of the financial market in better decision making. (shrink)

Developing an intellectualist account of skill, Stanley and Williamson define skill as a kind of disposition to action-guiding knowledge. The present paper challenges their definition of skill. While we don’t dispute that skill may consist of a cognitive, a dispositional, and an action-guiding component, we argue that Stanley and Williamson’s account of each component is problematic. In the first section, we argue, against Stanley and Williamson, that the cognitive component of skill is not a case of propositional knowledge-wh, which is (...) typically indexical. In the second section, we seek to show that Stanley and Williamson face difficulties in arguing for a generic claim about skill as a kind of disposition, and they fail to defend intellectualism about skill based on the dispositional account. In the third section we argue that Stanley and Williamson need a more detailed account of the action-guiding aspect of skill to avoid several difficulties, including a threat of a regress. We close with some lessons for the debate over intellectualism and anti-intellectualism about skill. (shrink)

Classification in statistics is usually used to solve the problems of identifying to which set of categories, such as subpopulations, new observation belongs, based on a training set of data containing information whose category membership is known. The article aims to use the Gaussian Mixture Model to model the daily closing price index over the period of 1/1/2013 to 16/8/2020 in the Kingdom of Saudi Arabia. The daily closing price index over the period declined, which might be the effect of (...) corona virus, and the mean of the study period is about 7866.965. The closing price is the last regular deal that took place during the continuous trading period. If there are no transactions on the stock during the day, the closing price is the previous day’s closing price. The closing auction period comes after the continuous trading period, during which investors can enter by buying and selling the stocks at this period. The experimental results show that the best mixture model is E with three components according to the BIC criterion. The expectation-maximization algorithm converged in 2 repetitions. The data source is from Tadawul KSA. (shrink)

The nomination of candidate genes underlying complex traits is often focused on genetic variations that alter mRNA abundance or result in non‐conservative changes in amino acids. Although inconspicuous in complex trait analysis, genetic variants that affect splicing or RNA editing can also generate proteomic diversity and impact genetic traits. Indeed, it is known that splicing and RNA editing modulate several traits in humans and model organisms. Using high‐throughput RNA sequencing (RNA‐seq) analysis, it is now possible to integrate the genetics of (...) transcript abundance, alternative splicing (AS) and editing with the analysis of complex traits. We recently demonstrated that both AS and mRNA editing are modulated by genetic and environmental factors, and potentially engender phenotypic diversity in a genetically segregating mouse population. Therefore, the analysis of splicing and RNA editing can expand not only the regulatory landscape of transcriptome and proteome complexity, but also the repertoire of candidate genes for complex traits.

The first part of the book examines language as a tool of logic, and deals with Alfarabi's analysis of the meanings of various terms as they are used in logic and philosophy.

This book explores the reaction of tenth-century Arab philosopher Abu Nasr Alfarabi to the logical works of Aristotle. From numerous short treatises the author develops a systematic and comprehensive topical survey of Alfara bi's logical writings. The book is divided into two major parts: language as a tool of logic and logic as a tool with which to analyze language. The first five chapters deal with Alfarabi's analysis of the meanings of various terms as they are used in logic and (...) philosophy. Alfarabi refutes the Arab grammarians who claimed that Arab logicians were building a language within a language and shows that the philosophical meanings of terms are in fact their most original and essential meanings. The final chapter deals with Alfarabi's analysis of certain aspects of the Arabic language and demonstrates that Arabic, like any natural language, conforms to universal logical structures of which natural languages are only a concrete expression.

In several experiments of survival analysis, the cause of death or failure of any subject may be characterized by more than one cause. Since the cause of failure may be dependent or independent, in this work, we discuss the competing risk lifetime model under progressive type-II censored where the removal follows a binomial distribution. We consider the Akshaya lifetime failure model under independent causes and the number of subjects removed at every failure time when the removal follows the binomial distribution (...) with known parameters. The classical and Bayesian approaches are used to account for the point and interval estimation procedures for parameters and parametric functions. The Bayes estimate is obtained by using the Markov Chain Monte Carlo method under symmetric and asymmetric loss functions. We apply the Metropolis–Hasting algorithm to generate MCMC samples from the posterior density function. A simulated data set is applied to diagnose the performance of the two techniques applied here. The data represented the survival times of mice kept in a conventional germ-free environment, all of which were exposed to a fixed dose of radiation at the age of 5 to 6 weeks, which was used as a practice for the model discussed. There are 3 causes of death. In group 1, we considered thymic lymphoma to be the first cause and other causes to be the second. On the base of mice data, the survival mean time of mice of the second cause is higher than the first cause. (shrink)

One of the goals of happiness research is to identify the key factors that influence it. Therefore, the present research is designed to examine the determining factors of subjective wellbeing in Pakistan. The present research is conducted by collecting the data of 1,566 households in Punjab, Pakistan, using the ordered logit and tobit model. The findings of this research confirm that income, education, government effectiveness, no perceived corruption, and perceived institutional quality improve wellbeing, while lower trust in family and friends, (...) poor health status, living on rent, and dissatisfaction with the services of hospitals lower the level of wellbeing. But individuals with more social ties, who face barriers in health services, live more happily satisfied with their lives. Crime victimization and worrisome terrorism also lower the level of SWB. Findings of research strongly emphasize policymakers and government institutions to improve their quality and take essential measures for improving the governance structure. (shrink)

This article aims to respond to the long-lived perceived incompatibility between care and compassion and justice in organizational literature. It is argued that principles of care and compassion and principles of justice are compatible with each other and can be integrated in organizations in such a way that both will supplement each other. Previous researches tend to view concepts of care and compassion and justice either as competing or inheriting some fundamental trade-offs. This article argues that the highlighted incompatibility between (...) care and compassion and justice is mainly due to the limited understanding about the nature of organizational justice. Care and compassion carry elements of subjectivity and are dynamic in nature, whereas literature on organizational justice has described justice as an objective, static and linear construct due to which an incompatibility between these two very important phenomena is prevailing. This incompatibility can be removed by changing the way of looking at organizational justice and by exploring its dynamic nature. (shrink)

[full article, abstract in English; abstract in Lithuanian] Armstrong’s theory of laws and causation may be articulated as something like the following, which we may refer to as the received view: “Laws are intrinsic higher-order relations of ensuring between properties. The instantiation of laws is identical with singular causation. This identity is a posteriori.” Opponents and advocates of this view, believe that it may fairly and correctly be attributed to Armstrong. I do not deny it; instead I seek to reconsider (...) the received view, specifically by treating it as a part of Armstrong’s metaphysics. The main features that should concern us are truthmaker theory and the formal account of the constitutive parts of states of affairs. I also discuss Bird’s ultimate argument against Armstrong and show how its impact is weakened by this proper reading. (shrink)

​Imagination will remain a mystery—we will not be able to explain imagination—until we can break it into parts we already understand. Explaining Imagination is a guidebook for doing just that, where the parts are other ordinary mental states like beliefs, desires, judgments, and decisions. In different combinations and contexts, these states constitute cases of imagining. This reductive approach to imagination is at direct odds with the current orthodoxy, according to which imagination is a sui generis mental state or process—one with (...) its own inscrutable principles of operation. Explaining Imagination upends that view, showing how, on closer inspection, the imaginings at work in hypothetical reasoning, pretense, the enjoyment of fiction, and creativity are reducible to other familiar mental states—judgments, beliefs, desires, and decisions among them. Crisscrossing contemporary philosophy of mind, cognitive science, and aesthetics, Explaining Imagination argues that a clearer understanding of imagination is already well within reach. (shrink)

Understanding and measuring levels of academic integrity within higher education institutions across the world is an important area of study in the era of educational internationalization. Developing a cross-cultural measure will undoubtedly assist in creating standardization processes and add to the discourse on cross-cultural understanding on what constitutes honest and dishonest action in the higher education context. This study has used a combination of exploratory and confirmatory factor analytical procedures to validate a previously published questionnaire, namely the cross-cultural academic integrity (...) questionnaire. Inspection of response distributions was also undertaken. Primary participants in this study were from Iran, and secondary reference participants were from New Zealand and Nigeria. The findings indicate that a revised questionnaire better represents the data obtained from all three regions. Three CCAIQ-2 domains are proposed: cheating, collusion and complying. However, the response distributions indicated differences among the three groups, further suggesting that the theoretical constructs developed through factors analysis may not represent equivalence in terms of cross-cultural understanding. This research will inevitably create international debate on the measurement of integrity and how this measurement process can be used to establish internationally recognized and accountable educational regulations.

If we are free to imagine what we choose, this is likely because our intentions determine what we are imagining. However, in a recent article, Munro and Strohminger (2021) argue that, in some cases of imagistic imagining, our intentions do not determine what we are imagining. They offer examples where, intuitively, a person intends to imagine one thing but, due to the causal source of the image used, imagine another. This paper acknowledges the challenge posed by these cases while arguing (...) on several grounds that, when present, intentions nevertheless always suffice to determine the object of one’s imaginings. I conclude by explaining how intentions could fix the objects of episodic rememberings in much the same way as they do for imaginings, thereby bolstering the case that remembering is a kind of imagining.

A popular view has it that the mental representations underlying human pretense are not beliefs, but are “belief-like” in important ways. This view typically posits a distinctive cognitive attitude (a “DCA”) called “imagination” that is taken toward the propositions entertained during pretense, along with correspondingly distinct elements of cognitive architecture. This paper argues that the characteristics of pretense motivating such views of imagination can be explained without positing a DCA, or other cognitive architectural features beyond those regulating normal belief and (...) desire. On the present “Single Attitude” account of imagination, propositional imagining just is a form of believing. The Single Attitude account is also distinguished from “metarepresentational” accounts of pretense, which hold that both pretending and recognizing pretense in others require one to have concepts of mental states. It is argued, to the contrary, that pretending and recognizing pretense require neither a DCA nor possession of mental state concepts. (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.

This study investigates the connection between following Islamic work ethics (IWE) and workplace deviance, and explores the role of perceived organizational politics as a mediator and the impact of incivility initiated by supervisors as a second-stage moderator. Data were collected via a two-wave survey of 205 professionals in various industries. Results show that those who adhere to IWE exhibit a negative link to workplace deviance, as they have less involvement in organizational politics. The study also finds that incivility initiated by (...) supervisors intensifies the positive relationship between perceived organizational politics and workplace deviance. Interestingly, the study shows that the effect of IWE in reducing workplace deviance through organizational politics is stronger when incivility is high. The findings offer valuable insights for organizations on the positive impact of adhering to IWE on reducing perceived organizational politics and workplace deviance. (shrink)

The (dis)continuism debate in the philosophy and cognitive science of memory concerns whether remembering is continuous with episodic future thought and episodic counterfactual thought in being a form of constructive imagining. I argue that settling that dispute will hinge on whether the memory traces (or “engrams”) that support remembering impose arational, perception-like constraints that are too strong for remembering to constitute a kind of constructive imagining. In exploring that question, I articulate two conceptions of memory traces—the replay theory and the (...) prop theory—that return conflicting answers to whether remembering is constructive imagining. The prop theory’s vision of traces is suggestive of continuism, while the replay theory’s is a natural fit for discontinuism. Which view of traces is in fact correct remains undetermined by current empirical work. Nevertheless, it may already be possible to reach a compromise in the (dis)continuism debate, through the development of a conciliatory continuist causal theory. This view—only outlined here—accepts the continuism-friendly prop theory of traces, while still requiring that genuine remembering fulfills an appropriate causation condition, as required by the kinds of causal theories of remembering typically favored by discontinuists.

The point of this paper is to reveal a dogma in the ordinary conception of sensory imagination, and to suggest another way forward. The dogma springs from two main sources: a too close comparison of mental imagery to perceptual experience, and a too strong division between mental imagery and the traditional propositional attitudes (such as belief and desire). The result is an unworkable conception of the correctness conditions of sensory imaginings—one lacking any link between the conditions under which an imagining (...) aids human action and inference and the conditions under which it is veridical. The proposed solution is, first, to posit a variety of imaginative attitudes—akin to the traditional propositional attitudes—which have different associated correctness (or satisfaction) conditions. The second part of the solution is to allow for imaginings with “hybrid” contents, in the sense that both mental images and representations with language-like constituent structure contribute to the content of imaginings.

This essay unites current philosophical thinking on imagination with a burgeoning debate in the philosophy of memory over whether episodic remembering is simply a kind of imagining. So far, this debate has been hampered by a lack of clarity in the notion of imagining at issue. Several options are considered and constructive imagining is identified as the relevant kind. Next, a functionalist account of episodic remembering is defended as a means to establishing two key points: first, one need not defend (...) a factive view of remembering in order to hold that causal connections to past experiences are essential to how rememberings are typed; and, second, current theories that equate remembering with imagining are in fact consistent with a functionalist theory that includes causal connections in its account of what it is to remember. This suggests that remembering is not a kind of imagining and clarifies what it would take to establish the contrary. (shrink)

Currie’s (2010) argument that “i-desires” must be posited to explain our responses to fiction is critically discussed. It is argued that beliefs and desires featuring ‘in the fiction’ operators—and not sui generis imaginings (or "i-beliefs" or "i-desires")—are the crucial states involved in generating fiction-directed affect. A defense of the “Operator Claim” is mounted, according to which ‘in the fiction’ operators would be also be required within fiction-directed sui generis imaginings (or "i-beliefs" and "i-desires"), were there such. Once we appreciate that (...) even fiction-directed sui generis imaginings would need to incorporate ‘in the fiction’ operators, the main appeal of the idea that sui generis imaginings (or "i-beliefs" or "i-desires") are at work in fiction-appreciation dissipates.

Martin and Deutscher’s causal theory of remembering holds that a memory trace serves as a necessary causal link between any genuine episode of remembering and the event it enables one to recall. In recent years, the causal theory has come under fire from researchers across philosophy and cognitive science, who argue that results from the scientific study of memory are incompatible with the kinds of memory traces that Martin and Deutscher hold essential to remembering. Of special note, these critics observe, (...) is that a single memory trace can be shaped by multiple past experiences. This appears to prevent traces from underwriting Martin and Deutscher’s distinction between remembering an event and merely forming an accurate representation of it. This paper accepts such criticisms of the standard causal theory and, through considering the phenomenon forgetting through repetition, raises several others. A substantially revised causal theory is then developed, compatible with the thesis that individual memory traces are shaped by multiple past experiences. The key strategy is to conceive of episodic remembering not as the simple retrieval and projection of a static memory trace, but as a complex quasi-inferential process that makes use of multiple forms of information and cues—“prop-like” memory traces included—in generating the experience known as episodic remembering. When remembering is understood as a multi-componential process, there are a variety of ways in which a representation of the past may be appropriately causally dependent upon a prior experience of the event remembered.

If imagination is subject to the will, in the sense that people choose the content of their own imaginings, how is it that one nevertheless can learn from what one imagines? This chapter argues for a way forward in addressing this perennial puzzle, both with respect to propositional imagination and sensory imagination. Making progress requires looking carefully at the interplay between one’s intentions and various kinds of constraints that may be operative in the generation of imaginings. Lessons are drawn from (...) the existing literature on propositional imagination and from the control theory literature concerning the prediction and comparison mechanisms (or “forward models”) involved in ordinary perception. A more general conclusion is reached that, once we have the tools to understand how some imaginings are both under willful control and helpfully guide action and inference, we will have what we need to understand the cognitive basis of imagination in general.

Whether a person is pretending, or not, is a function of their beliefs and intentions. This poses a challenge to 4E accounts of pretense, which typically seek to exclude such cognitive states from their explanations of psychological phenomena. Resulting tensions are explored within three recent accounts of imagination and pretense offered by theorists working in the 4E tradition. A path forward is then charted, through considering ways in which explanations can invoke beliefs and intentions while remaining true to 4E precepts. (...) To make real progress in explaining pretense, 4E theorists will need to grow comfortable with the idea that two agents whose outward behaviors and environments are, in the short term, the same, may be guided by quite different beliefs and intentions, in virtue of which only one is pretending. In this way, the scientific project of explaining pretense remains inseparable from the more general project of determining which beliefs and intentions are appropriate to ascribe to which kinds of entities, given which kinds of behaviors.

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)

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)

It is often observed that images—including mental images—are in some sense representationally ambiguous. Some, including Jerry Fodor, have added that mental images only come to have determinate contents through the contribution of non-imagistic representations that accompany them. This paper agrees that a kind of ambiguity holds with respect to mental imagery, while arguing (pace Fodor) that this does not prevent imagery from having determinate contents in the absence of other, non-imagistic representations. Specifically, I argue that mental images can represent determinate (...) types of outlays of properties without help from any non-imagistic representations, yet can only become involved in the representation of particular objects through pairing with a non-imagistic representation of the right sort. These points are defended through reflection on the “Picture Principle,” the nature of depiction, and general principles for typing and individuating mental states. (shrink)

It is widely held that introspection-based self-ascriptions of mental states are immune to error through misidentification , relative to the first person pronoun. Many have taken such errors to be logically impossible, arguing that the immunity holds as an “absolute” necessity. Here I discuss an actual case of craniopagus twins—twins conjoined at the head and brain—as a means to arguing that such errors are logically possible and, for all we know, nomologically possible. An important feature of the example is that (...) it is one where a person may be said to be introspectively aware of a mental state that occurs outside of her own mind. Implications are discussed for views of the relation between introspection and mental state ownership, and between introspection and epistemic criteria for the “mark of the mental.”. (shrink)

Much of what we say is never said aloud. It occurs only silently, as inner speech. We chastise, congratulate, joke and cajole, all without making a sound. This distinctively human ability to create public language in the privacy of our own minds is no less remarkable for its familiarity. And yet, until recently, inner speech remained at the periphery of philosophical and psychological theorizing. This essay collection, from an interdisciplinary group of leading philosophers, psychologists, and neuroscientists, displays the rapidly growing (...) interest among researchers in the puzzles surrounding the nature and cognitive role of the inner voice. Questions explored include: the aids and obstacles inner speech presents to self-knowledge; the complex relation it bears to overt speech production and perception; the means by which inner speech can be identified and empirically assessed; its role in generating auditory verbal hallucinations; and its relationship to conceptual thought itself.

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.
