A long-standing question in cognitive science is how high-level knowledge is integrated with sensory input. For example, listeners can leverage lexical knowledge to interpret an ambiguous speech sound, but do such effects reflect direct top-down influences on perception or merely postperceptual biases? A critical test case in the domain of spoken word recognition is lexically mediated compensation for coarticulation (LCfC). Previous LCfC studies have shown that a lexically restored context phoneme (e.g., /s/ in Christma#) can alter the perceived place of (...) articulation of a subsequent target phoneme (e.g., the initial phoneme of a stimulus from a tapes-capes continuum), consistent with the influence of an unambiguous context phoneme in the same position. Because this phoneme-to-phoneme compensation for coarticulation is considered sublexical, scientists agree that evidence for LCfC would constitute strong support for top–down interaction. However, results from previous LCfC studies have been inconsistent, and positive effects have often been small. Here, we conducted extensive piloting of stimuli prior to testing for LCfC. Specifically, we ensured that context items elicited robust phoneme restoration (e.g., that the final phoneme of Christma# was reliably identified as /s/) and that unambiguous context-final segments (e.g., a clear /s/ at the end of Christmas) drove reliable compensation for coarticulation for a subsequent target phoneme. We observed robust LCfC in a well-powered, preregistered experiment with these pretested items (N = 40) as well as in a direct replication study (N = 40). These results provide strong evidence in favor of computational models of spoken word recognition that include top–down feedback. (shrink)

Visual word recognition is facilitated by the presence of orthographic neighbors that mismatch the target word by a single letter substitution. However, researchers typically do not consider where neighbors mismatch the target. In light of evidence that some letter positions are more informative than others, we investigate whether the influence of orthographic neighbors differs across letter positions. To do so, we quantify the number of enemies at each letter position (how many neighbors mismatch the target word at that position). Analyses (...) of reaction time data from a visual word naming task indicate that the influence of enemies differs across letter positions, with the negative impacts of enemies being most pronounced at letter positions where readers have low prior uncertainty about which letters they will encounter (i.e., positions with low entropy). To understand the computational mechanisms that give rise to such positional entropy effects, we introduce a new computational model, VOISeR (Visual Orthographic Input Serial Reader), which receives orthographic inputs in parallel and produces an over‐time sequence of phonemes as output. VOISeR produces a similar pattern of results as in the human data, suggesting that positional entropy effects may emerge even when letters are not sampled serially. Finally, we demonstrate that these effects also emerge in human subjects' data from a lexical decision task, illustrating the generalizability of positional entropy effects across visual word recognition paradigms. Taken together, such work suggests that research into orthographic neighbor effects in visual word recognition should also consider differences between letter positions. (shrink)

Despite the lack of invariance problem (the many‐to‐many mapping between acoustics and percepts), human listeners experience phonetic constancy and typically perceive what a speaker intends. Most models of human speech recognition (HSR) have side‐stepped this problem, working with abstract, idealized inputs and deferring the challenge of working with real speech. In contrast, carefully engineered deep learning networks allow robust, real‐world automatic speech recognition (ASR). However, the complexities of deep learning architectures and training regimens make it difficult to use them to (...) provide direct insights into mechanisms that may support HSR. In this brief article, we report preliminary results from a two‐layer network that borrows one element from ASR, long short‐term memory nodes, which provide dynamic memory for a range of temporal spans. This allows the model to learn to map real speech from multiple talkers to semantic targets with high accuracy, with human‐like timecourse of lexical access and phonological competition. Internal representations emerge that resemble phonetically organized responses in human superior temporal gyrus, suggesting that the model develops a distributed phonological code despite no explicit training on phonetic or phonemic targets. The ability to work with real speech is a major advance for cognitive models of HSR. (shrink)

Multiple cortical areas of the human brain motor system interact coherently in the low frequency range (< 0.1 Hz), even in the absence of explicit tasks. Following stroke, cortical interactions are functionally disturbed. How these interactions are affected and how the functional organization is regained from rehabilitative treatments as people begin to recover motor behaviors has not been systematically studied. We recorded the intrinsic functional magnetic resonance imaging (fMRI) signals from 30 participants: 17 young healthy controls and 13 aged stroke (...) survivors. Stroke participants underwent mental practice (MP) or both mental practice and physical therapy (MP + PT) within 14-51 days following stroke. We investigated the network activity of five core areas in the motor-execution network, consisting of the left primary motor area (LM1), the right primary motor area (RM1), the left pre-motor cortex (LPMC), the right pre-motor cortex (RPMC) and the supplementary motor area (SMA). We discovered that (i) the network activity dominated in the frequency range 0.06 Hz – 0.08 Hz for all the regions, and for both able-bodied and stroke participants (ii) the causal information flow between the regions: LM1 and SMA, RPMC and SMA, RPMC and LM1, SMA and RM1, SMA and LPMC, was reduced significantly for stroke survivors (iii) the flow did not increase significantly after MP alone and (iv) the flow among the regions during MP+PT increased significantly. We also found that sensation and motor scores were significantly higher and correlated with directed functional connectivity measures when the stroke-survivors underwent MP+PT but not MP alone. The findings provide evidence that a combination of mental practice and physical therapy can be an effective means of treatment for stroke survivors to recover or regain the strength of motor behaviors, and that the spectra of causal information flow can be used as a reliable biomarker for evaluating rehabilitation in stroke survivors.

This paper criticizes two closely connected rationalist views about human agency. The first of these views, rationalism about agential control, claims that the capacities for agential control in normal adult human beings are rational capacities. The second view, rationalism about action, claims that the capacities for agential control in virtue of which the things we do count as our actions are rational capacities. The arguments of the paper focus on aspects of technical skills that control integral details of skillful action, (...) like the details of a baseball player’s pitching technique. I argue that these aspects of technical skills are largely non-rational capacities, but are nonetheless capacities for agential control, and can help make the things we do count as actions. While rational capacities do have a central role in human agency, their importance should not lead us to neglect the significant constitutive role of non-rational capacities in our agency. (shrink)

This paper argues that you have non-observational warrant for beliefs about the body in action. For example, if you mean to be drinking a cup of water, you can know independently of observation that you are moving your body in a way that is effective in enabling you to drink. The case I make centers on the claim that you have default warrant to trust your agency. You do well to trust your agency just in virtue of your status as (...) an agent, and are not required to earn permission to trust your agency through making use of evidence about how well your agency works. You have non-observational warrant for beliefs about the functioning of your agency, including beliefs about your body in action, inasmuch as those beliefs reflect trust in your agency. (shrink)

There is widespread disagreement about whether epistemic akrasia is possible. This paper argues that the possibility of epistemic akrasia follows from a traditional rationalist conception of epistemic critical reasoning, together with considerations about the fallibility of our capacities for reasoning. In addition to defending the view that epistemic akrasia is possible, we aim to shed light on why it is possible. By focusing on critical epistemic reasoning, we show how traditional rationalist assumptions about our core cognitive capacities help to explain (...) the possibility of epistemic akrasia. (shrink)

The study aims to ascertain how different levels of society have been influenced by the impact of pandemics over the last many years. The study also determines the societal implications of the COVID-19 pandemic. The integrative literature survey method is adopted to extract the secondary data pertinent to the socio-economic effect of pandemics and COVID-19 on society. Primary data is collected to diagnose the impact of the COVID-19 pandemic and lockdown on employees (N = 210) working in the Indian organized (...) sector. Findings of the study suggest that pandemics have been a cause of economic slowdown measured with a fall in gross domestic product (GDP) at the macro level. The reduced level of economic activity is found to be negatively related to an individual socio-economic status building their psychological distress. The descriptive analysis of the data reveals that although employees have managed their jobs and finances during COVID-19, they have experienced stress in their lives due to the pandemic. The study assimilates the pandemic effect using inductive reasoning to develop a COVID quadrilateral conceptual framework. (shrink)

While Aristotle claims that virtuous actions are choiceworthy for their own sakes, he also claims that many virtuous actions are to be chosen as instrumental means to securing further ends. It would seem that an action is choiceworthy for its own sake only if it would be choiceworthy whether or not it served further ends. How, then, can such virtuous actions be choiceworthy for their own sakes? This article criticizes John Ackrill's and Jennifer Whiting's answers to this question. I propose (...) an alternative, linking the choiceworthiness of virtuous actions to the pleasure, nobility, and beauty to be found in them. (shrink)

Purpose The high rate of internet penetration has led to the proliferation of social media use, even at the workplace, including academia. This research attempts to develop a topology and thereby determine the dominant use motive for faculty’s use of SM. Design/methodology/approach In this two-part study, a two-stage research design has been adopted for topology development based on the application of Uses and Gratifications Theory. In the second part, the Technology Acceptance Model is applied to discern the dominant motive for (...) SM use in academia. Findings The work is able to develop a seven-item topology, conforming to the basic three use motives, namely, hedonic, utilitarian and social. The work shows faculty attach more value to the instrumental utility of SM, while the hedonic function is also significant. Practical implications Discerning dominant motive implies that SM use at the workplace should not be banned, rather effective regulated use will instil the faculty to enhance work outcomes. The conceptualisation of topology for SM use in academia at the workplace can aid in designing an effective organisation policy, and design of an internal SM platform. Originality/value The study is unique towards topology development for academic faculty and has many important implications for management and academia, especially towards policy design for SM use at the workplace.

This paper attempts to theorise the labour and corporeal carcerability of the non-citizen non-subjects in contemporary democracies of the United States and India. I reappropriate Joy James’ framework of ‘Captive Maternals’ to understand the relationality between the undocumented, racialised, or incarcerated with the neo-liberal states that they inhabit and serve but where they do not belong. James describes Captive Maternals as those bodies subject to consumption by the democratic order in the tradition of slavery. I expand upon her framework to (...) argue that the dehumanisation of illegal ‘aliens’ and racially policed bodies not only challenges the notion of freedom in the modern democratic social organisation but rather manifests the fundamental correlation between democratic sovereignty and its exclusionary violence. This phenomenon internal to the workings of democracies challenges Hegel’s idealisation of the modern rational state as the most advanced form of government characterised primarily by freedom. Democracy also constitutes the exercise of necropolitical sovereignty which I interpret not as the right to kill but as the right to police and incarcerate. Against the Hegelian struggle for recognition (Anerkennung), I deliberate on the possibility of transcending to a less than fully-determined Sittlichkeit that does not rely upon reciprocal recognition.

We propose that hyper‐inflammation (HYPi) is a ‘‘runaway’’ consequence of acute inflammation (ACUi) that arises more easily (and also abates less easily) in those who host a pre‐existing chronic inflammation (CHRi), because (i) most factors involved in generating an ACUi to limit viral proliferation are already present when there is an underlying CHRi, and also because (ii) anti‐inflammatory (AI) mechanisms for the abatement of ACUi (following containment of viral proliferation) are suppressed and desensitized where there is an underlying CHRi, with (...) this causing the ACUi to spiral into a HYPi. Stress, pollution, diet, and gut microbiomes (alterable in weeks through dietary changes) have an intimate and bidirectional cause‐effect relationship with CHRi. We propose that avoidance of CHRi‐promoting foods and adoption of CHRi‐suppressing foods could reduce susceptibility to HYPi, in Covid‐19 and in other viral diseases, such as influenza, which are characterized by episodic and unpredictable HYPi.

The study contributes to the marketing ethics literature, particularly to the literature related to ethical issues in product marketing. (shrink)

In India, judicial review is not a static phenomenon. It has ensured that the Constitution is the supreme law of the land, and in situations when a law impinges on the rights and the liberties of citizens, it can be pruned or made void. This is a collection of scholarly essays demonstrating the different facets of judicial review based on the vast area of comparative constitutional law. Importantly, it honours the body of work of Upendra Baxi, legal scholar and author, (...) whose contributions have shaped our understanding of legal jurisprudence and expanded the scope of social transformation in India. This volume recognizes his role as an Indian jurist. Various constitutional law experts come together to reflect on his expositions on the role of the apex court, judicial activism, accountability of judiciary, laws on surrogacy and adultery and so on.

The Chinese government capped executive compensation in state-owned enterprises (SOEs) to address income inequality and promote a more equitable distribution of wealth. This study investigates whether regulating top executives' pay alters their motivation for corporate green innovation (GI) initiatives. Using data from 2006 to 2018 for Chinese-listed SOEs, the regression analysis and difference-in-difference methods revealed that government restrictions on executive compensation negatively affect GI. Furthermore, the types of SOE results show that the negative effect of pay restrictions on GI exists (...) only in local SOEs, as opposed to central SOEs. Moreover, high managerial shareholding positively moderates this negative effect, demonstrating that the adverse effects of compensation restrictions are mitigated by the convergence of interests between managers and stakeholders. These findings are robust to instrumental variables and other robustness tests. This study provides policy recommendations for the government to boost its assistance in GI and establish new environment-related incentives that motivate managers to promote GI and inspire enterprises to deploy sustainable environmental initiatives.

This article aims to improve the understanding of corporate governance and environmental reporting literature by analyzing the impact of board gender diversity (BGD) on environmental performance, environmental disclosure, and greenwashing behavior. The panel regression estimation technique with fixed effects was applied to Chinese firm data. As a result, it was found that more women who served on corporate boards enhanced the company's environmental performance and disclosures while limiting greenwashing behavior. The result indicated that women in top management play a constructive (...) role in establishing firms' active environmental initiatives. Furthermore, this relationship was nonlinear and exponentially increased when women's representation reached the threshold of 33.5% representation on board or higher. Based on the findings, no internal bias was found even after other governance and firm-level control factors and probable endogenies were considered and variable biases were omitted. Notably, the results present important implications for regulators and policymakers by highlighting the influential role of BGD in promoting environmentally responsible practices and reducing greenwashing.

Luthra, Peraza-Santiago, Beeson, Saltzman, Crinnion, and Magnuson (2021) present data from the lexically mediated compensation for coarticulation paradigm that they claim provides conclusive evidence in favor of top-down processing in speech perception. We argue here that this evidence does not support that conclusion. The findings are open to alternative explanations, and we give data in support of one of them (that there is an acoustic confound in the materials). Lexically mediated compensation for coarticulation thus remains elusive, while prior data (...) from the paradigm instead challenge the idea that there is top-down processing in online speech recognition.
