Stimuli that resemble humans, but are not perfectly human-like, are disliked compared to distinctly human and nonhuman stimuli. Accounts of this “Uncanny Valley” effect often focus on how changes in human resemblance can evoke different emotional responses. We present an alternate account based on the novel hypothesis that the Uncanny Valley is not directly related to ‘human-likeness’ per se, but instead reflects a more general form of stimulus devaluation that occurs when inhibition is triggered to resolve conflict between competing (...) stimulus-related representations. We consider existing support for this inhibitory-devaluation hypothesis and further assess its feasibility through tests of two corresponding predictions that arise from the link between conflict-resolving inhibition and aversive response: 1) that the pronounced disliking of Uncanny-type stimuli will occur for any image that strongly activates multiple competing stimulus representations, even in the absence of any human-likeness, and 2) that the negative peak of an ‘Uncanny Valley’ should occur at the point of greatest stimulus-related conflict and not (in the presence of human-likeness) always closer to the ‘human’ end of a perceptual continuum. We measured affective responses to a set of line drawings representing nonhuman animal-animal morphs, in which each continuum midpoint was a bistable image (Exp. 1), as well as to sets of human-robot and human-animal computer-generated morphs (Exp. 2). Affective trends depicting classic Uncanny Valley functions occurred for all continua, including the nonhuman stimuli. Images at continua midpoints elicited significantly more negative affect than images at endpoints, even when the continua included a human endpoint. This illustrates the feasibility of the inhibitory-devaluation hypothesis and the need for further research into the possibility that the strong dislike of Uncanny-type stimuli reflects the negative affective consequences of cognitive inhibition.

The framework of Findlay & Walker's target article provides a first attempt to model the saccadic system at all levels. Their scheme is based on two main principles. These are “parallel processing of saccade timing and metrics” and “competitive inhibition through winner-take-all strategies.” In our opinion, however, both concepts are in their strictest sense at odds with the current knowledge of the saccadic system, and need to be refined to make the scheme more relevant.

During active vision, the eyes continually scan the visual environment using saccadic scanning movements. This target article presents an information processing model for the control of these movements, with some close parallels to established physiological processes in the oculomotor system. Two separate pathways are concerned with the spatial and the temporal programming of the movement. In the temporal pathway there is spatially distributed coding and the saccade target is selected from a Both pathways descend through a hierarchy of levels, the (...) lower ones operating automatically. Visual onsets have automatic access to the eye control system via the lower levels. Various centres in each pathway are interconnected via reciprocal inhibition. The model accounts for a number of well-established phenomena in target-elicited saccades: the gap effect, express saccades, the remote distractor effect, and the global effect. High-level control of the pathways in tasks such as visual search and reading is discussed; it operates through spatial selection and search selection, which generally combine in an automated way. The model is examined in relation to data from patients with unilateral neglect. (shrink)

Deciding between different voluntary movements implies a continuous control of the competition between potential actions. Many theories postulate a leading role of prefrontal cortices in this executive function, but strong evidence exists that a motor region like the primary motor cortex is also involved, possibly via inhibitory mechanisms. This was already shown during the pre-movement decision period, but not after movement onset. For this pilot experiment we designed a new task compatible with the dynamics of post-onset control to study the (...) silent period duration, a pause in electromyographic activity after single-pulse transcranial magnetic stimulation that reflects inhibitory mechanisms. A careful analysis of the SP during the ongoing movement indicates a gradual increase in inhibitory mechanisms with the level of competition, consistent with an increase in mutual inhibition between alternative movement options. However, we also observed a decreased SP duration for high-competition trials associated with change-of-mind inflections in their trajectories. Our results suggest a new post-onset adaptive process that consists in a transient reduction of GABAergic inhibition within M1 for highly conflicting situations. We propose that this reduced inhibition softens the competition between concurrent motor options, thereby favoring response vacillation, an adaptive strategy that proved successful at improving behavioral performance.

The use of performance-enhancing drugs is a significant problem in sport. It cheats clean athletes of their hard-earned rewards from perfecting their skills though dedication and hard work. It defrauds fans by substituting a distorted playing field for a true competition. Anti-doping agencies have been charged with enforcing drug policies, primarily through the use of drug testing programs. We propose that drug testing, while important, is not sufficient to achieve deterrence. Engaging the principles of perceptual deterrence and development of a (...) moral community of athletes can greatly enhance compliance with rules. (shrink)

The precompetitive, competitive, and postcompetitive mental states of athletes are currently not sufficiently researched. Long-term exposure to stressors contributes to the formation of mental blocks and leads to various health problems. One of the factors that can explain the variability of athletes' reactions to stress is their personality. This study is the first to examine competitive anxiety, and guilt and shame proneness in the context of the reaction of football players to distress in sports. The study consists of (...) 112 male football players aged 16–24 who were divided into type D and non-type D football players according to scoring on the Denollet Scale. Football players also filled out the Sport Anxiety Scale and the Guilt and Shame Proneness Scale. The taxonomic approach was conducted to test and to examine differences in stressor intensity as a function of type D personality. A correlation, multivariate analysis of variance, and regression analysis were performed in the study. We found that type D football players were more afraid of failures in sports, felt more often autonomous excitement concentrated in the stomach and muscles, and showed more frequent concentration disruption than did non-type D football players. We also found that although type D football players were more likely to rate their behavior as negative and inappropriate, they showed a much greater effort to correct it than did non-type D football players. Negative affectivity and social inhibition of type D football players were positively correlated with competitive anxiety. In addition, we noted lower levels of somatic anxiety and lower concentration disruption for football players who used escape strategies to manage stress. The shame proneness subscale monitoring negative self-evaluation was also closely related to the concentration disruption of football players. We found that the examination of athletes by type D personality is necessary due to the fact that negative affectivity and social inhibition are significant predictors of competitive anxiety of football players, which explains their worries at 24.0%, somatic anxiety at 8.2%, and concentration disruption at 10.6%.

.Evolutionary analysis focuses on how genes build organisms with different strategies for engaging and solving life’s challenges of survival and reproduction. One of those challenges is competing with conspecifics for limited resources including reproductive opportunities. This article will suggest that there is now good evidence for considering two dimensions of social competition. First, we will label antisocial strategies, to the extent that they tend to be self-focused, threat sensitive and aggressive, as well as using tactics of bulling, threatening, intimidating or (...) even injuring/killing competitors. Their strategic goal is to stimulate fear-inhibition, flight or submissive compliance in subordinates. Such strategies turn off and inhibit care and affiliative social interactions and motivation and they can be enacted by parents, teachers and leaders. The social signals emitted stimulate various aspects of threat processing in recipients, create stressful and highly stratified groups with a range of detrimental psychological and physiological effects. Second, in contrast, prosocial strategies seek to create relaxed and secure social interactions that enable sharing, cooperative and mutually supportive and beneficial relationships. The friendly and low/no threat social signals emitted in friendly cooperative and affiliative relationships stimulate physiological systems (e.g., oxytocin, the vagus parasympathetic system) that down regulates threat processing, enhances the immune system, facilitates frontal cortical processes and general wellbeing. This article reviews the literature pertaining to the evidence for these two dimensions of social engagement. (shrink)

This 1989 volume presents a theory of capitalist collective action and a case study of the pre-World War II American coal industry to which the theory is applied. The author examines the irony of capitalist firms that do not want to compete with each other, but often cannot avoid doing so. He then explains under what conditions businesses would be able to organize their competition and identifies the economic and political factors that facilitate or inhibit this organization. The case study (...) not only illustrates the theory, but demonstrates how the competitive relations of capitalist firms are critically important determinants of their political behavior. The author argues that the traditional Marxist concern with conflict between workers and capitalists should be supplemented with a concern for the competitive conflicts among capitalists. (shrink)

An experimental study was conducted on children aged 2;6–3;0 and 3;6–4;0 investigating the priming effect of two WANT-constructions to establish whether constructional competition contributes to English-speaking children's infinitival to omission errors. In two between-participant groups, children either just heard or heard and repeated WANT-to, WANT-X, and control prime sentences after which to-infinitival constructions were elicited. We found that both age groups were primed, but in different ways. In the 2;6–3;0 year olds, WANT-to primes facilitated the provision of to in target (...) utterances relative to the control contexts, but no significant effect was found for WANT-X primes. In the 3;6–4;0 year olds, both WANT-to and WANT-X primes showed a priming effect, namely WANT-to primes facilitated and WANT-X primes inhibited provision of to. We argue that these effects reflect developmental differences in the level of proficiency in and preference for the two constructions, and they are broadly consistent with “priming as implicit learning” accounts. The current study shows that children as young as 2;6–3;0 years of age can be primed when they have only heard particular constructions, children are acquiring at least two constructions for the matrix verb WANT, and that these two WANT-constructions compete for production.

Proper wiring of the nervous system requires tight control of the number of nerve terminals that innervate a target tissue. Recent work by Deppmann et al.,1 now suggests that this is achieved by feedback‐mediated neuronal competition for target‐derived survival cues. The authors' model is inspired by the theory for pattern formation based on self‐activation and lateral inhibition, proposed by Meinhardt and Gierer more than 30 years ago.2 BioEssays 30:929–933, 2008. © 2008 Wiley Periodicals, Inc.

This paper presents a computer model of cortical broadcast and competition based on spiking neurons and inspired by the hypothesis of a global neuronal workspace underlying conscious information processing in the human brain. In the model, the hypothesised workspace is realised by a collection of recurrently inter-connected regions capable of sustaining and disseminating a reverberating spatial pattern of activation. At the same time, the workspace remains susceptible to new patterns arriving from outlying cortical populations. Competition among these cortical populations for (...) influence on the workspace is effected by a combination of mutual inhibition and top-down amplification. (shrink)

Purpose This study aims to address the existing knowledge gap by investigating teachers’ adoption of ChatGPT for educational purposes. The study specifically focuses on identifying the factors that motivate and inhibit teachers in adoption of ChatGPT in higher education institutions (HEIs). Design/methodology/approach This research has used interpretative phenomenological analysis – a qualitative approach. Through in-depth interviews among the teachers, data was collected to identify the motivating and inhibiting factors that impacted teachers’ willingness to adopt ChatGPT. The data was collected from (...) 48 teachers working across HEIs of Uttarakhand region in India. Findings The analysis revealed seven themes under motivating factors that encourage teachers to adopt ChatGPT for their educational purposes. These include time factor, tool for competitive edge, learning enhancement tool for students, research facilitator, benefits in educational settings, troubleshooter and easy to use. On the other hand, inhibiting factors comprise five themes, which include technical difficulties, limited features for educational and research purposes, tool for handicapping innovation and creativity, lack of personal touch and ethical considerations. Practical implications The findings will be valuable for HEIs in establishing policies that promote the appropriate and effective use of ChatGPT. Moreover, the study provides recommendations to ChatGPT solution providers for improving ChatGPT services for effective adoption of ChatGPT among teachers and implementation at HEIs. Further, it contributes to the body of literature by filling a knowledge gap about teacher adoption of ChatGPT in the HEIs. Through qualitative research, the study has pinpointed specific motivating and inhibiting factors that affect teacher adoption of ChatGPT. Originality/value Unlike previous studies that primarily explored the potential advantages and drawbacks of ChatGPT in education, this research study delves deeper into the topic. It makes a substantial contribution to our understanding of ChatGPT adoption among teachers by identifying distinct factors that either motivate or inhibit teachers from adopting ChatGPT for job related purposes. The study provides novel insights that were previously mislaid, thereby introducing a fresh perspective to the existing literature. (shrink)

Goal-directed spatial decision making video games combine spatial mapping, memory, and reward; all of which can involve hippocampal excitation through suppression of an inhibitory neurotransmitter, γ-aminobutyric acid. In this study, GABA was measured before and after 30 min of video game play within a voxel around the hippocampus. It was predicted that all participants would experience a decrease in GABA during gaming as a result of in-game rewards; and, those who were most competitive with the goal-directed spatial decision making (...) game would display lower hippocampal GABA concentrations after gaming. Those who were not competitive, because they were too skilled or not skilled enough, would demonstrate higher hippocampal GABA concentrations after gaming. While there were no significant differences in hippocampal GABA before and after gaming for gamers and non-gamers alike, there was a significant quadratic regression between performance on a spatial working memory task and post-gaming hippocampal GABA concentrations.

A quintessential challenge for any perceptual system is the need to focus on task-relevant information without being blindsided by unexpected, yet important information. The human visual system incorporates several solutions to this challenge, one of which is a reflexive covert attention system that is rapidly responsive to both the physical salience and the task-relevance of new information. This paper presents a model that simulates behavioral and neural correlates of reflexive attention as the product of brief neural attractor states that are (...) formed across the visual hierarchy when attention is engaged. Such attractors emerge from an attentional gradient distributed over a population of topographically organized neurons and serve to focus processing at one or more locations in the visual field, while inhibiting the processing of lower priority information. The model moves towards a resolution of key debates about the nature of reflexive attention, such as whether it is parallel or serial, and whether suppression effects are distributed in a spatial surround, or selectively at the location of distractors. Most importantly, the model develops a framework for understanding the neural mechanisms of visual attention as a spatiotopic decision process within a hierarchy and links them to observable correlates such as accuracy, reaction time, and the N2pc and PD components of the EEG. This last contribution is the most crucial for repairing the disconnect that exists between our understanding of behavioral and neural correlates of attention. (shrink)

The genetic code has been regarded as arbitrary in the sense that the codon-amino acid assignments could be different than they actually are. This general idea has been spelled out differently by previous, often rather implicit accounts of arbitrariness. They have drawn on the frozen accident theory, on evolutionary contingency, on alternative causal pathways, and on the absence of direct stereochemical interactions between codons and amino acids. It has also been suggested that the arbitrariness of the genetic code justifies attributing (...) semantic information to macromolecules, notably to DNA. I argue that these accounts of arbitrariness are unsatisfactory. I propose that the code is arbitrary in the sense of Jacques Monod's concept of chemical arbitrariness: the genetic code is arbitrary in that any codon requires certain chemical and structural properties to specify a particular amino acid, but these properties are not required in virtue of a principle of chemistry. This notion of arbitrariness is compatible with several recent hypotheses about code evolution. I maintain that the code's chemical arbitrariness is neither sufficient nor necessary for attributing semantic information to nucleic acids. (shrink)

Animal research suggests that central serotonergic neurons are involved in behavioral suppression, particularly anxiety-related inhibition. The hypothesis linking decreased serotonin transmission to reduced anxiety as the mechanism in the anxiolytic activity of benzodiazepines conflicts with most clinical observations. Serotonin antagonists show no marked capacity to alleviate anxiety. On the other hand, clinical signs of reduced serotonergic transmission (low 5-HIAA levels in the cerebrospinal fluid) are frequently associated with aggressiveness, suicide attempts, and increased anxiety. The target article attempts to reconcile (...) such human and animal findings by investigating whether anxiety reduction or increased impulsivity is more Likely to account for animal behavioral changes associated with decreased serotonergic transmission. The effects of manipulating central serotonin in experimental anxiety paradigms in animals (punishment, extinction, novelty) are reviewed and compared with the effects of antianxiety drugs. Anxiety seems neither necessary nor sufficient to induce control by serotonergic neurons on behavior. Further evidence suggests that behavioral effects of anxiolytics thought to be mediated by decreases in anxiety are not caused by the ability of these drugs to reduce serotonin transmission. Blockade of serotonin transmission, especially at the level of the substantia nigra, results in a shift of behavior toward facilitation of responding. This behavioral shift is particularly marked when there is competition between acting and restraining response tendencies and when obstacles prevent the immediate attainment of an anticipated reward. It is proposed that serotonergic neurons are involved not only in behavioral arousal but also in enabling the organism to arrange or tolerate delay before acting. Decreases in serotonin transmission seem to be associated with the increased performance of behaviors that are usually suppressed, though not necessarily because of the alleviation of anxiety, which might contribute to the suppression.

Pigment cells in zebrafish − melanophores, iridophores, and xanthophores − originate from neural crest‐derived stem cells associated with the dorsal root ganglia of the peripheral nervous system. Clonal analysis indicates that these progenitors remain multipotent and plastic beyond embryogenesis well into metamorphosis, when the adult color pattern develops. Pigment cells share a lineage with neuronal cells of the peripheral nervous system; progenitors propagate along the spinal nerves. The proliferation of pigment cells is regulated by competitive interactions among cells of (...) the same type. An even spacing involves collective migration and contact inhibition of locomotion of the three cell types distributed in superimposed monolayers in the skin. This mode of coloring the skin is probably common to fish, whereas different patterns emerge by species specific cell interactions among the different pigment cell types. These interactions are mediated by channels involved in direct cell contact between the pigment cells, as well as unknown cues provided by the tissue environment. (shrink)

How do we transmit or distribute knowledge, as distinct from generating or producing it? In this book John Greco examines the interpersonal relations and social structures which enable and inhibit the sharing of knowledge within and across epistemic communities. Drawing on resources from moral theory, the philosophy of language, action theory and the cognitive sciences, he considers the role of interpersonal trust in transmitting knowledge, and argues that sharing knowledge involves a kind of shared agency similar to giving a gift (...) or passing a ball. He also explains why transmitting knowledge is easy in some social contexts, such as those involving friendship or caregiving, but impossible in contexts characterized by suspicion and competition rather than by trust and cooperation. His book explores phenomena that have been undertheorized by traditional epistemology, and throws new light on existing problems in social epistemology and the epistemology of testimony. (shrink)

This study examines the social impacts of labor-related corporate social responsibility policies or corporate codes of conduct on upholding labor standards through a case study of CSR discourses and codes implementation of Reebok - a leading branded company enjoying a high-profiled image for its human rights achievement - in a large Taiwanese-invested athletic footwear factory located in South China. I find although implementation of Reebok labor-related codes has resulted in a "race to ethical and legal minimum" labor standards when notoriously (...) inhumane and seriously illegal labor rights abuses were curbed, Chinese workers were forced to work harder and faster but, earned less payment and the employee-elected trade union installed through codes implementation operated more like a "company union" rather than an autonomous workers' organization representing worker' interests. In order to explain the paradoxical effects of Reebok labor-related codes on labor standards, I argue the result is determined by both structural forces and agency-related factors embedded in industrial, national and local contexts. To put it shortly, I find the effectiveness of Reebok labor-related codes is constrained not only by unsolved tension between Reebok's impetus for profit maximization and commitment to workers' human rights, but also by hard-nosed competition realities at marketplace, and Chinese government's insufficient protection of labor rights. Despite drawing merely from a single case study, these findings illuminate key determinants inhibiting the effectiveness of labor-related CSR policies or codes in upholding labor standards, and hence two possible way-outs of the deadlock: sharing cost for improving labor standards among key players in global supply chain; and combining regulatory power of voluntary codes and compulsory state legislations.

My main purpose here is to provide an account of context selection in utterance understanding in terms of the role played by schemata and goals in top-down processing. The general idea is that information is organized hierarchically, with items iteratively organized in chunks—here called “schemata”—at multiple levels, so that the activation of any items spreads to schemata that are the most accessible due to previous experience. The activation of a schema, in turn, activates its other components, so as to predict (...) a likely context for the original item. Since each input activates its own schemata, conflicting schemata compete with (and inhibit) each other, while multiple activations of a schema raise its likelihood to win the competition. There is therefore a double movement—with bottom-up activation of schemata enabling top-down prediction of other contextual components—triggered by multiple sources. Another claim of the paper is that goals are represented by schemata placed at the highest-levels of the executive hierarchy, in accordance with Fuster’s model of the brain as a hierarchically organized perception action cycle. This account can be considered, in part at least, a development of ideas contained in Relevance Theory, though it may imply that some other claims of the theory are in need of revision. Therefore, a secondary purpose of the paper is a contribution to the analysis of that theory. (shrink)

Conflict can profoundly affect individuals and their groups. Oftentimes, conflict involves a clash between one side seeking change and increased gains through victory and the other side defending the status quo and protecting against loss and defeat. However, theory and empirical research largely neglected these conflicts between attackers and defenders, and the strategic, social, and psychological consequences of attack and defense remain poorly understood. To fill this void, we model (1) the clashing of attack and defense as games of strategy (...) and reveal that (2) attack benefits from mismatching its target's level of defense, whereas defense benefits from matching the attacker's competitiveness. This suggests that (3) attack recruits neuroendocrine pathways underlying behavioral activation and overconfidence, whereas defense invokes neural networks for behavioral inhibition, vigilant scanning, and hostile attributions; and that (4) people invest less in attack than defense, and attack often fails. Finally, we propose that (5) in intergroup conflict, out-group attack needs institutional arrangements that motivate and coordinate collective action, whereas in-group defense benefits from endogenously emerging in-group identification. We discuss how games of attack and defense may have shaped human capacities for prosociality and aggression, and how third parties can regulate such conflicts and reduce their waste. (shrink)

The ascription of intentional states to the self involves knowledge, or at least claims to knowledge. Armed with the working definition of knowledge as 'the ability to do things, or refrain from doing things, or believe, or want, or doubt things, for reasons that are facts' [Hyman, J. Philos. Quart. 49:432—451], I sketch a simple competence model of acting and believing from knowledge and when knowledge is defeated by un-experienced changes of state. The model takes the form of three concentric (...) circles. The 'periphery' is analogous to Fodor's [(1983), The modularity of mind. MIT Press, Cambridge, MA] input systems. The 'core' contains copies of peripheral representations, and between these representations there is executive competition. At the 'nucleus', operations are performed on the core representations of, at least, negation and recursion. I argue that this provides a fruitful way in which to conceptualise why theory-of-mind tasks challenge pre-school children, how some degree of first-person authority is mental state attribution is possible, and how executive inhibition is achieved.

Males in many non-monogamous species have larger ranges than females do, a sex difference that has been well documented for decades and seems to be an aspect of male mating competition. Until recently, parallel data for humans have been mostly anecdotal and qualitative, but this is now changing as human behavioral ecologists turn their attention to matters of individual mobility. Sex differences in spatial cognition were among the first accepted psychological sex differences and, like differences in ranging behavior, are documented (...) for a growing set of species. This special issue is dedicated to exploring the possible adaptive links between these cognitive and ranging traits. Multiple hypotheses, at various levels of analysis, are considered. At the functional (ultimate) level, a mating-competition hypothesis suggests that range expansion may augment mating opportunities, and a fertility-and-parental-care hypothesis suggests that range contraction may facilitate offspring provisioning. At a more mechanistic (proximate) level, differences in cue availability may support or inhibit particular sex-specific navigation strategies, and spatial anxiety may usefully inhibit travel that would not justify its costs. Studies in four different cultures—Twe, Tsimane, Yucatec Maya, and Faroese—as well as an experimental study using virtual reality tools are the venue for testing these hypotheses. Our hope is to stimulate more research on the evolutionary and developmental processes responsible for this suite of linked behavioral and cognitive traits. (shrink)

In approaching the question of whether groups of people can have cognitive capacities that are fundamentally different than the cognitive capacities of the individuals within the group, we lay out a Multiple, Interactive Levels of Cognitive Systems (MILCS) framework. The goal of MILCS is to explain the kinds of cognitive processes typically studied by cognitive scientists, such as perception, attention, memory, categorization, decision making, problem solving, and judgment. Rather than focusing on high-level constructs such as modules in an information processing (...) flow diagram or internal representations, MILCS focuses on mechanisms that allow systems to engage in flexible, adaptive behavior. Examples of these mechanisms are network structure-process pairs that: combine data from perception with top-down theories, achieve consistency and consensus through information exchange, selectively attend to information globally assessed as relevant, and develop specialized units from originally homogeneous networks through competition among the units. Two such systems are considered in some detail -- lateral inhibition within a network for selecting from a candidate set the option that is most attractive, and a diffusion process for accumulating evidence to reach a generally rapid and accurate decision. These system descriptions are aptly applied at multiple levels, including within and across people. These systems provide accounts that unify cognitive processes across multiple levels, can be expressed in a common vocabulary provided by network science, are inductively powerful yet appropriately constrained, and are applicable to a large number of superficially diverse cognitive systems. Given that people are typically highly motivated to participate in strong groups, cognitively resourceful people will tend to form groups that effectively employ cognitive systems at higher levels than the individuals. The impressive cognitive capacities of individual people do not eliminate the need to talk about group cognition. Instead, smart people generally form smart groups. (shrink)

Non‐invasive brain stimulation is used to modulate brain excitation and inhibition and to improve cognitive functioning. The effectiveness of the enhancement due to transcranial direct current stimulation (tDCS) is still controversial, but the technique seems to have large potential for improvement and more specific applications. In particular, it has recently been used by athletes, both beginners and professionals. This paper analyses the ethical issues related to tDCS enhancement, which depend on its specific features: ease of use, immediate effect, non‐detectability (...) and great variability of effects. If tDCS were to become widespread, there could be some potential side effects, especially the rise of inequality in many selective competitive contexts. I discuss two possible scenarios to counter this effect: that of prohibition and that of compensation, each supported by reasons and arguments that seem plausible and worthy of consideration. In conclusion, I show why I think the scenario of compensation is the preferable one. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:DisaffiliationsBeauvoir and Gorz on Masculinity as AgingPenelope DeutscherThe same drama of flesh and spirit, and of finitude and transcendence, plays itself out in both sexes; both are eaten away by time, stalked by death.The Second Sex, 763Simone de Beauvoir wrote her second large theoretical work in 1970, La Vieillesse (V), some nine years after André Gorz published a two-part article, “Le Vieillissement,” in Les Temps Modernes, in 1961 and (...) 1962. These were essays in which Gorz did not hesitate to refer to the “conflict between generations.” He found unremarkable the constant transitions involved in what he saw as a combat between younger and older age groups, unremarkable that the young would resent the domination of the aged and find themselves resented in turn. The aged would bear heavily on the young, but eventually find themselves demeaned if not subordinated by them.Since Gorz was one of the many references in La Vieillesse, Beauvoir was using resources that could have prompted her to think of youth and aging as a further domain of group-based conflict and hostility. Instead, she preferred a different language. Stories that might have seemed to be those of inter-generational conflict were present in her work—she mentions a story from the Brothers Grimm of three generations: son, father, and grandfather. The father treats the grandfather abusively until he learns that his son accordingly anticipates repeating the same treatment toward him. But Beauvoir does not narrate the story as one of conflict between groups who should be understood as “generations.”1 For Gorz, by contrast, such relations seem inevitable. He writes [End Page 88] of young men frustrated by their disenfranchisement by older men, who are in turn disenfranchised as young men eventually manage to usurp them.Just as the language of group-based conflict seems to Gorz obvious to describe such relations, so does the tacit (though not overtly noted) masculinity of their experience. But because he does not directly note that the conflict, on his own account, occurs between the younger and older generations of males, it is not clear how a vision of generational conflict might be inflected by a sense that such relations are also those of sexual difference. How might that affect relations between the sexes or relations among women of different ages?For her part, Beauvoir did refer to tensions between younger and older women, both in The Second Sex (SS) and Old Age(OA), but these were largely references to relations between mothers and daughters. They were familial stories. Certainly, they were refracted through structure and social context: It is the impoverished status and history of women that, in Beauvoir’s view, inhibits their lives to the point that mothers and daughters resent each other. But describing such tensions, Beauvoir does not present them as competition between groups. Her visions are those of individual experiences occurring in family contexts, not those of a generation of women of a particular age group, understanding each other as engaged in some kind of potentially conflictual group relations with a group of women understood as generationally younger or older. This is not to say that Beauvoir ought to have preferred the language of generational conflict in considering aging. But in understanding that she turned away, without saying so, from a model that might well have seemed most plausible, we can think further about the interpretation that did seem more plausible to her.How, then, do aging and sex interact for Beauvoir? Her presentation of aging in The Second Sex is characteristically ambivalent. She describes middle-aged women who have bet on the norms of femininity—“She has counted on her sexual attributes far more than man has” (SS, 620)—only to be confronted with the dilemmas of the transformation brought by time. Beauvoir takes this transformation to be largely negative—comprehended in terms of loss rather than possible gain. She describes the physical transformation of aging in terms of degeneration and the passing of youth, beauty, health, innovation, capacity. She also claims, albeit with an important exception, that it is experienced by the woman negatively, with accompanying effects of shock, discontinuity, crisis, anxious concern, denial... (shrink)

Most theorisations of fascism, Marxist and otherwise, have taken for granted its idolatry of the state and phobia of freedom. This analytical common sense has also inhibited the identification of continuities with contemporary movements of the far Right, with their libertarian and anti-statist affectations, not to mention their embeddedness in neoliberal policies and subjectivities. Drawing on a range of diverse sources – from Johann Chapoutot’s histories of Nazi intellectuals to Ruth Wilson Gilmore’s theorisation of the anti-state state, and from Marcuse’s (...) explorations of fascist competitive individualism to debates on neoliberal authoritarianism – this essay sketches the counter-intuitive but disturbingly timely image of a fascism enamoured of freedom and at odds with the state.

A broad range of behavior is associated with crossmodal perception in the arts. Philosophical explanations of crossmodal perception often make reference to neuroscientific discussions of multisensory integration in selective attention. This research demonstrates that superior colliculus plays a regulative role in attention, integrating unique modality specific visual, auditory, and somatosensory spatial maps into a common spatial framework for action, and that motor skill, emotional salience, and semantic salience contribute to the integration of auditory, visual, and somatosensory information in ordinary perceptual (...) contexts. I present a model for multisensory integration in our engagement with artworks derived from a diagnostic recognition framework for object recognition and a biased competition model for selective attention. The proposed model attributes a role to superior colliculus in a broader fronto-parietal attentional network that integrates sensory information, primes perceptual systems to the expectation of stimulus features salient to particular sensorimotor or cognitive tasks at particular locations, and inhibits the perception of task irrelevant distracters. I argue that this model demonstrates that crossmodal effects are the rule not the exception in perception and discuss ways in which it explains a range of crossmodal effects in our engagement with pictures, dance, and musical performances.

A model of when and where saccades are made necessarily incorporates a model of the “When” and “Where” of target selection. We suggest that the framework proposed by Findlay & Walker does not specify sufficiently how selection processes contribute to the spatial and temporal determinants of saccade generation. Examples from across-trial priming in visual search and from the inhibition of temporally segmented distractors show linkage between the processes involved in computing when and where selection operates, so that there is (...) cooperation rather than competition between so-called Where and When pathways. Aspects of spatial selection may also determine the remote distractor effect on saccades. The detailed relations between the processes involved in selection and saccade generation may be best understood in relation to detailed computational accounts of the processes. (shrink)

This study examines the social impacts of labor-related corporate social responsibility (CSR) policies or corporate codes of conduct on upholding labor standards through a case study of CSR discourses and codes implementation of Reebok – a leading branded company enjoying a high-profiled image for its human rights achievement – in a large Taiwanese-invested athletic footwear factory located in South China. I find although implementation of Reebok labor-related codes has resulted in a “race to ethical and legal minimum” labor standards when (...) notoriously inhumane and seriously illegal labor rights abuses were curbed, Chinese workers were forced to work harder and faster but, earned less payment and the employee-elected trade union installed through codes implementation operated more like a “company union” rather than an autonomous workers’ organization representing worker’ interests. In order to explain the paradoxical effects of Reebok labor-related codes on labor standards, I argue the result is determined by both structural forces and agency-related factors embedded in industrial, national and local contexts. To put it shortly, I find the effectiveness of Reebok labor-related codes is constrained not only by unsolved tension between Reebok’s impetus for profit maximization and commitment to workers’ human rights, but also by hard-nosed competition realities at marketplace, and Chinese government’s insufficient protection of labor rights. Despite drawing merely from a single case study, these findings illuminate key determinants inhibiting the effectiveness of labor-related CSR policies or codes in upholding labor standards, and hence two possible way-outs of the deadlock: (1) sharing cost for improving labor standards among key players in global supply chain; and (2) combining regulatory power of voluntary codes and compulsory state legislations.

We raise the new possibility that people diagnosed with developmental dyslexia (DD) are specialized in explorative cognitive search, and rather than having a neurocognitive disorder, play an essential role in human adaptation. Most DD research has studied educational difficulties, with theories framing differences in neurocognitive processes as deficits. However, people with DD are also often proposed to have certain strengths – particularly in realms like discovery, invention, and creativity – that deficit-centered theories cannot explain. We investigate whether these strengths reflect (...) an underlying explorative specialization. We re-examine experimental studies in psychology and neuroscience using the framework ofcognitive search, whereby many psychological processes involve a trade-off between exploration and exploitation. We report evidence of an explorative bias in DD-associated cognitive strategies. High DD prevalence and an attendant explorative bias across multiple areas of cognition suggest the existence of explorative specialization. An evolutionary perspective explains the combination of findings and challenges the view that individuals with DD have a disorder. In cooperating groups, individual specialization is favored when features that confer fitness benefits are functionally incompatible. Evidence for search specialization suggests that, as with some other social organisms, humans mediate the exploration–exploitation trade-off by specializing in complementary strategies. The existence of a system of collective cognitive search that emerges through collaboration would help to explain our species’ exceptional adaptiveness. It also aligns with evidence for substantial variability during our evolutionary history and the notion that humans are adapted not to a particular habitat but to variability itself. Specialization creates interdependence and necessitates balancing complementary strategies. Reframing DD therefore underscores the urgency of changing certain cultural practices to ensure we do not inhibit adaptation. Key improvements would remove cultural barriers to exploration and nurture explorative learning in education, academia, and the workplace, as well as emphasize collaboration over competition. Specialization in complementary search abilities represents a meta-adaptation; through collaboration, this likely enables human groups (as a species and as cultural systems) to successfully adapt. Cultural change to support this system of collaborative search may therefore be essential in confronting the challenges humanity now faces. (shrink)

I have attempted to clarify some of the pathways in the development of Darwin's thinking. The foregoing examples of influence by no means include all that can be found by comparing Darwin's writings with Humboldt's. However, the above examples seem adequate to show the nature and extent of this influence. It now seems clear that Humboldt not only, as had been previously known, inspired Darwin to make a voyage of exploration, but also provided him with his basic orientation concerning how (...) and what to observe and how to write about it. An important part of what Darwin assimilated from Humboldt was an appreciation of population analysis as a tool for assessing the state of societies and of the benefits and hardships which these societies can expect to receive from the living world around them.Darwin exhibited in his Journal of Researches a casual interest in the economic and political conditions of the countries he visited, but these considerations were much less important to him than to Humboldt. Instead, Darwin, with the assistance of Lyell's Principles of Geology, shifted from Humboldt's largely economic framework to a biological one built around the species question. This shift led Darwin away from a consideration of how the population biology of animals was related to man's economy to focus instead upon how population biology fitted into the economy of nature.Humboldt's Personal Narrative served very well as a model for Darwin's Journal of Researches, thereby helping Darwin gain scientific eminence. The Journal of Researches, like virtually all of Humboldt's writings, was a contribution to scientific orthodoxy. But Darwin had, along the way, acquired an urge to do more than just add his building blocks to the orthodox scientific edifice. He decided to rearrange those blocks of knowledge into a different structure, and for that task neither Humboldt's Personal Narrative nor any other of his works could serve as a model. Humboldt had lacked the confidence which Darwin needed that biogeography and the origin of species could be understood. Humboldt had not explored very far the possible connections between biology and geology. Nor had he provided a general synthetic account of population biology. Had he done so, he might have been more explicit about the extent of his endorsement of Malthus. But even if he had, Humboldt's strong orientation toward cooperation would probably have inhibited his recognition of the importance of competition in nature.Lyell, who had also benefited from reading Humboldt, gave Darwin insights that were lacking in Humboldt's Personal Narrative. Lyell admirably demonstrated how stratigraphy, paleontology, biogeography, and population biology could be interrelated, and his reasons for doing so were essentially the same as Darwin's. Lyell's understanding of biogeography and ecology came from the writings of Augustin-Pyramus de Candolle as much as from Humboldt's, and from the former Lyell derived an appreciation for the importance of competition and also a confidence that the mysteries of biogeography could be explained.117 Furthermore, Lyell's discussion of all these subjects and also of evolution in his Principles of Geology is a good synthetic argument that was the ideal model for Darwin's greatest book.Darwin, having become convinced that species change through time, was able to synthesize in his mind the contributions which he had derived from the writings of Humboldt and Lyell as they applied to the species question. When Darwin wrote his Journal of Researches there were two large gaps in his thinking about evolution that bothered him—the mechanism of evolution and the causes of extinction. It was only after reading Malthus in 1838 that he realized, as Lyell had more or less pointed out, how important was competition in nature. He now had the general outlines for his theory, and in the 1845 abridged edition of his Journal, now retitled The Voyage of the Beagle, he inserted a fuller discussion of competition in nature which showed his awareness of its importance as an ecological factor.118.

Evolutionary analysis suggests that policies based on deterrence may cope effectively with primary sociopathy if the threat of punishment fits the crime in the cost/benefit calculus of the sociopath, not that of the public. On the other hand, policies designed to offset serious disadvantage in social competition may help inhibit the development of secondary sociopathy, rather than deter its expression.

This paper analyzes the impact mechanism of executive poverty experience on innovation performance from the two logics of “innate endowment” and “endogenous power.” It then explores the moderating role of executive characteristics, firm nature, and market competition from the perspective of heterogeneity, and finally proves the influence mechanism. Using the data of Chinese A-share listed companies from 2012 to 2020, the empirical results show that executives’ poverty experience improves corporate innovation performance. Further studies find that female executives with poverty experience (...) have a more significant impact on innovation performance. Additionally, state-owned enterprises weaken the positive effects of executives with poverty experiences on innovation performance. The impact of executive poverty experience on innovation performance is more significant in fierce market competition. The mediating result suggests that executive poverty experience improves innovation performance partly by inhibiting R&D manipulation. The findings remain valid through Propensity Score Matching tests, the Heckman two-stage, and alternative indicator measures. Using the early life poverty experience of executives, this study promotes research on the factors influencing corporate innovation. It also provides empirical evidence for improving corporate innovation performance through a study of moderating effects and influencing mechanisms. (shrink)

Teaching the art of profession-related communication to students of non-linguistic study fields allows instructors to explain their students how to keep up the conversation using facts, data, concepts etc. specific to the area of their future profession. It activates the acquisition processes as well as increases students' motivation to study. The formation of oral monologue speaking skills in students of non-linguistic study fields is one of the tasks within the course of Foreign ( English) Language for Specific Purposes.This process is (...) associated with certain difficulties, which can inhibit learning and demotivated students to study. Among strategies and techniques aiding learning that can be used to improve performance and study outcomes during the course and can be implemented for the enhancement of speaking on occupation-related topics, the mind mapping technique is of specific relevance. It can serve as an interesting and useful tool serving to enhance quality of oral speaking skills in students majoring in Psychology as the representatives of non-linguistic study fields. The article analyses the carried out research concerning the facilitating impact of mind mapping on the oral speech performance of Psychology students. The study hypothesis implies that the use of the mind-mapping technique in the process of preparing for and presenting the talk in the study sessions enhances students' oral monologue speech performance. In order to check the hypothesis, we have conducted the experiment in Bohdan Khmelnytsky National University of Cherkasy at the Department of Psychology. The study involved 46 first-year students, including 34 female and 12 male participants. The respondents were randomly assigned to the experimental mind-mapping group of 23 students ( including 6 males) and the control group of 23 students ( including 6 males as well). The students in the experimental group were involved into the experiment using the mind-mapping technique during their study, and the students in the control group continued their study in the usual way. The hypothesis was confirmed. The mind map use stimulates activity of both brain hemispheres, thus making it easier for students to memorize thematic vocabulary, follow the logical sequence of the talk when speaking. The research findings have shown the effectiveness of implementing the mind-mapping technique into the university course teaching English for Specific Purposes to develop, advance and master students' professional communicative competence. Consistent use of mind maps will also promote the educational process efficiency and have positive effects on the general formation of competitive skilled specialists. (shrink)

Cancer stem cells (CSC) represent malignant cell subsets in hierarchically organized tumors, which are selectively capable of tumor initiation and self‐renewal and give rise to bulk populations of non‐tumorigenic cancer cell progeny through differentiation. Robust evidence for the existence of prospectively identifiable CSC among cancer bulk populations has been generated using marker‐specific genetic lineage tracking of molecularly defined cancer subpopulations in competitive tumor development models. Moreover, novel mechanisms and relationships have been discovered that link CSC to cancer therapeutic resistance (...) and clinical tumor progression. Importantly, proof‐of‐principle for the potential therapeutic utility of the CSC concept has recently been provided by demonstrating that selective killing of CSC through a prospective molecular marker can inhibit tumor growth. Herein, we review these novel and translationally relevant research developments and discuss potential strategies for CSC‐targeted therapy in the context of resistance mechanisms and molecular pathways preferentially operative in CSC.

Governing greenwashing in environmental, social, and governance (ESG) disclosure is an important issue, but relevant literature is scant. Based on the data on Chinese A-share listed firms from 2012 to 2021, we investigate the governance role of corporate digital transformation (DT) in ESG greenwashing and its influencing mechanism. We find that DT significantly inhibits ESG greenwashing. Moreover, DT mitigates ESG greenwashing by enhancing corporate green technology innovation (i.e., innovation channel), reducing information asymmetry (i.e., information channel), and increasing trade credit (i.e., (...) resource channel). From the perspective of investor attention, we find that both retail investors' online opinions and institutional investors' site visits strengthen the inhibitory effect of DT on ESG greenwashing. Furthermore, such an inhibitory effect is more pronounced in large firms, industries with high competition, and regions with strong intellectual property protection. This research provides new insights and policy suggestions for governing corporate ESG greenwashing behavior. (shrink)

The examination of how words are learned can offer valuable insights into the nature of lexical representations. For example, a common assessment of novel word learning is based on its ability to interfere with other words; given that words are known to compete with each other, we can use the capacity of a novel word to interfere with the activation of other lexical representations as a measure of the degree to which it is integrated into the mental lexicon. This measure (...) allows us to assess novel word learning in L1 or L2, but also the degree to which representations from the two lexica interact with each other. Despite the somewhat independent lines of research on L1 and L2 word learning, common patterns emerge across the two literatures. In both cases, lexicalization appears to follow a similar trajectory. In L1, newly encoded words often fail at first to engage in competition with known words, but they do so later, after they have been better integrated into the mental lexicon. Similarly, L2 words generally have a facilitatory effect, which can, however, become inhibitory in the case of more robust lexical representations. Despite the similar pattern, L1 lexicalization is described in terms of inter-lexical connections, leading to more automatic processing ; whereas in L2 word learning, lack of lexical inhibition is attributed to less robust L2 lexical representations. Here, I point to these similarities and I use them to argue that a common mechanism may underlie similar patterns across the two literatures. (shrink)
