Many scholars have investigated the relationship between protest and repression. Less often examined is the legislative suppression of protest by elites seeking to make protest more costly to protesters. Because state legislatures are largely invisible to the public, this “wholesale” suppression of protest is less likely to trigger public opposition than repression by the police. This study explains the sharp increase in the number and the severity of state legislative bills to repress the right to protest both before (...) and after the election of Donald Trump. In particular, it examines whether these can be attributed either to Republican control of state legislatures or to protest threat. Contrary to the findings in much of the literature, bills aimed at suppressing protest are less closely related to threat than to the realignment of state politics. The article also finds that these proposals were influenced by diffusion through policy brokerage. (shrink)

Ignorance can excuse otherwise blameworthy action, but only if the ignorance itself is blameless. One way to avoid culpable ignorance is to pay attention when epistemic peers disagree. Expressed disagreements place an obligation on the agent to pay attention when an interlocutor disagrees, or risk culpable ignorance for which they might later be found blameworthy. Silence, on the other hand, is typically taken as assent. But in cases of suppressed disagreement, the silenced interlocutor has information that could save the agent (...) from ignorance in scenarios where that ignorance might lead to harmful action, and silence does not actually indicate assent. The problem is further complicated because the agent might not be aware of the fact that a silenced interlocutor has information that could prevent ignorance, and consequent harmful action. In this paper, I provide a new account of excuses from ignorance in situations of suppressed disagreement. I do this in the context of two cases; Kelly’s hypothetical case of the Tyrannical Dictator, and the real-world case of former South African President Thabo Mbeki and his AIDS denialist policies in the late 1990s and early 2000s.

The current study investigated age differences in the use of attentional deployment, positive reappraisal and suppression while regulating responses to sadness-eliciting content. We also tested to what extent these emotion regulation strategies were useful for each age group in managing response to age-relevant sad information. Forty-two young participants (Mage = 18.5, SE =.15) and 48 older participants (Mage = 71.42, SE = 1.15) watched four sadness-eliciting videos (about death/illness, four to five minutes long) under four conditions—no-regulation (no regulation (...) instructions), attentional deployment (divert attention away), positive reappraisal (focus on positive outcomes) and suppression (conceal emotional expressions). We assessed negative emotional experience, expression, skin conductance level (SCL) and visual fixation duration while participants watched the emotional clips and followed the instructions for each condition. Results suggest that older adults were more successful than younger adults at implementing both attentional deployment and positive reappraisal. Ability to suppress emotions appears to remain stable with age. Within age-group comparisons suggested that for the older adults, positive reappraisal was a more useful emotion regulation strategy than the others, while the pattern among younger adults was less conclusive. Age-relevant differences in motivation and successful emotion regulatory efforts based on theoretical and empirical literatures are discussed. (shrink)

The aging process involves changes in immune regulation, i.e. adaptive immunity declines whereas innate immunity becomes activated. NF‐κB signaling is the master regulator of the both immune systems. Two recent articles highlight the role of the NF‐κB system in aging and immune responses. Adler et al1 showed that the NF‐κB binding domain is the genetic regulatory motif which is most strongly associated with the aging process. Kwon et al2 studying HIV‐1 infection and subsequent immune deficiency process demonstrated that HIV‐1 Tat (...) protein binds to SIRT1 protein, a well‐known longevity factor, and inhibits the SIRT1‐mediated deacetylation of the p65 component of the NF‐κB complex. As a consequence, the transactivation efficiency of the NF‐κB factor was greatly potentiated, leading to the activation of immune system and later to the decline of adaptive immunity. These observations support the scenario where immune responses and aging process can be enforced by the potentiation of NF‐κB transactivation efficiency. Longevity factors, such as SIRT1 and its activators, might regulate the efficiency of the NF‐κB signaling, the major outcome of which is inflamm‐aging via proinflammatory responses.

We thank the commentators for their thoughtful responses to our article.1 Due to space constraints, we will confine our discussion to just three key issues. The first issue relates to the central ethical conundrum for clinicians working with young people like Phoenix: namely, how to respect, value and defer to a person’s own account of their identity and what is needed for their well-being, while staying open to the possibility that such an account may reflect a work in progress. This (...) conundrum thus relates both to what will be beneficial for that person and what constitutes respecting their autonomy, and clinicians must dwell on these questions when deciding what forms of medical intervention to offer. D’Angelo,2 Lemma3 and Wren4 highlight the importance of considering Phoenix as a ‘whole person in context’ 2 prior to initiating treatment or care. In this way, they advocate for a process of ‘therapeutic exploration’,4 which includes taking sufficient time to explore Phoenix’s personhood with them so as to support them in achieving an ‘authentic self-discovery’.2 We agree with these authors that identity development is a complex, life-long process that is influenced by biological, psychosocial and relational aspects, all of which may contribute to an individual’s desire to pursue gender-affirming interventions. To explore the various factors—both conscious and unconscious—that might be motivating Phoenix’s decision to pursue ongoing puberty suppression, D’Angelo,2 Lemma3 and Wren4 describe a comprehensive psychological approach to working with transgender and gender diverse individuals and propose questions to guide such discussions. Consistent with this approach, we stipulated that Phoenix had undergone regular psychological counselling and that the psychologist had judged that ‘Phoenix’s distress is significant and enduring…not a symptom ….

Introduction: Advantageous effects of biological motion detection, a low-perceptual mechanism that allows the rapid recognition and understanding of spatiotemporal characteristics of movement via salient kinematics information, can be amplified when combined with motor imagery, i.e., the mental simulation of motor acts. According to Jeannerod’s neurostimulation theory, asynchronous firing and reduction of mu and beta rhythm oscillations, referred to as suppression over the sensorimotor area, are sensitive to both MI and action observation of BM. Yet, not many studies investigated the (...) use of BM stimuli using combined AO-MI tasks. In this study, we assessed the neural response in the form of event-related synchronization and desynchronization patterns following the observation of point-light-walkers and concordant MI, as compared to MI alone.Methods: Twenty right-handed healthy participants accomplished the experimental task by observing BM stimuli and subsequently performing the same movement using kinesthetic MI. We recorded an electroencephalogram with 32 channels and performed time-frequency analysis on alpha and beta frequency bands during the MI task. A two-way repeated-measures ANOVA was performed to test statistical significance among conditions and electrodes of interest.Results: The results revealed significant ERD/S patterns in the alpha frequency band between conditions and electrode positions. Post hoc comparisons showed significant differences between condition 1 and condition 3 over the left primary motor cortex. For the beta band, a significantly less difference in ERD patterns was detected only between condition 3 and condition 4.Discussion: Our results confirmed that the observation of BM combined with MI elicits a neural suppression, although just in the case of jumping. This is in line with previous findings of AO and MI eliciting a neural suppression for simulated whole-body movements. In the last years, increasing evidence started to support the integration of AOMI training as an adjuvant neurorehabilitation tool in Parkinson’s disease.Conclusion: We concluded that using BM stimuli in AOMI training could be promising, as it promotes attention to kinematic features and imitative motor learning.

Modus ponens is the argument from premises of the form If A, then B and A to the conclusion B. Nearly all participants agree that the modus ponens conclusion logically follows when the argument appears in this Basic form. However, adding a further premise can lower participants’ rate of agreement—an effect called suppression. We propose a theory of suppression that draws on contemporary ideas about conditional sentences in linguistics and philosophy. Semantically, the theory assumes that people interpret an (...) indicative conditional as a context-sensitive strict conditional: true if and only if its consequent is true in each of a contextually determined set of situations in which its antecedent is true. Pragmatically, the theory claims that context changes in response to new assertions, including new conditional premises. Thus, the conclusion of a modus ponens argument may no longer be accepted in the changed context. Psychologically, the theory describes people as capable of reasoning about broad classes of possible situations, ordered by typicality, without having to reason about individual possible worlds. The theory accounts for the main suppression phenomena, and it generates some novel predictions that new experiments confirm. (shrink)

The controversy over vaccines has recently intensified in the wake of the global COVID-19 pandemic, with calls from politicians, health professionals, journalists, and citizens to take harsh measures against so-called “anti-vaxxers,” while accusing them of spreading “fake news” and as such, of endangering public health. However, the issue of suppression of vaccine dissenters has rarely been studied from the point of view of those who raise concerns about vaccine safety. The purpose of the present study was to examine the (...) subjective perceptions of professionals (physicians, nurses, researchers) involved with vaccines through practice and/or research and who take a critical view on vaccines, about what they perceive as the suppression of dissent in the field of vaccines, their response to it, and its potential implications on science and medicine. Respondents reported being subjected to a variety of censorship and suppression tactics, including the retraction of papers pointing to vaccine safety problems, negative publicity, difficulty in obtaining research funding, calls for dismissal, summonses to official hearings, suspension of medical licenses, and self-censorship. Respondents also reported on what has been termed a “backfire effect” – a counter-reaction that draws more attention to the opponents’ position. Suppression of dissent impairs scientific discourse and research practice while creating the false impression of scientific consensus. (shrink)

The attentional blink (AB) is an impairment of attention, which occurs when subjects have to report a target stimulus (T2) following a previous target (T1) with a short delay (up to 600 ms). Theories explaining the AB assume that processing of T2 is more vulnerable to decay or substitution, as long as attention is allocated to T1. Existing models of the AB, however, do not account for the fact that T2 detection accuracy reaches the minimum when T2 is presented after (...) about 300 ms and not immediately following T1. Therefore, a new model is suggested, which is based on chronometrical considerations together with recent neurophysiological findings concerning the relation between the P3 event-related potential and the AB, the interaction between P3 and gamma oscillations, and the significance of the early evoked gamma band response. We hypothesize that suppression of the early gamma response to T2, accompanying the P3 related to T1, causes the AB. (shrink)

The accessibility of suppressed thoughts was compared with the accessibility of thoughts on which Ss were consciously trying to concentrate. In Experiment I, Ss made associations to word prompts as they tried to suppress thinking about a target word (e.g., house) or tried to concentrate on that word. Under the cognitive load imposed by time pressure, they gave the target word in response to target-related prompts (e.g., home) more often during suppression than during concentration. In Experiment 2, reaction (...) times for naming colors of words were found to be greater under conditions of cognitive load when Ss were asked to suppress thinking of the word than under conditions of no cognitive load or when Ss were asked to concentrate on the word. The results support the idea that an automatic search for the suppression target increases the accessibility of the target during.. (shrink)

The explanation of the suppression of Modus Ponens inferences within the framework of linguistic pragmatics and of plausible reasoning (i.e., deduction from uncertain premises) is defended. First, this approach is expounded, and then it is shown that the results of the first experiment of Byrne, Espino, and Santamar a (1999) support the uncertainty explanation but fail to support their counterexample explanation. Second, two experiments are presented. In the first one, aimed to refute one objection regarding the conclusions observed, the (...) additional conditional premise ( if N, C ) was replaced with a statement of uncertainty ( it is not certain that N ); the answers produced by the participants remained qualitatively and quantitatively similar in both conditions. In the second experiment, a fine-grained analysis of the responses to and justifications for an evaluation task was performed. The results of both experiments strongly supported the uncertainty explanation. (shrink)

In plants, virus‐derived double‐stranded RNA is processed into small interfering (si)RNAs by RNAse III‐type enzymes. siRNAs are believed to guide an RNA‐induced silencing complex (RISC) to promote sequence‐specific degradation (or ‘slicing’) of homologous viral transcripts. This process, called RNA silencing, likely involves Argonaute (AGO) proteins that are known components of plant and animal RISCs. Plant viruses commonly counteract the silencing immune response by producing suppressor proteins, but the molecular basis of their action has remained largely unclear. A recent study (...) by Zhang and colleagues1 now shows that the 2b suppressor of Cucumber mosaic virus directly interacts with Arabidopsis AGO1 and inhibits its slicing activity, suggesting that AGO1 might be a component of the elusive plant antiviral RISC.

Information processing that subserves conscious cognitive functions is thought to involve recurrent signaling through feedforward and feedback loops among hierarchically arranged functional regions of the cerebral cortex. In the current issue of Consciousness and Cognition, Lee et al. report that loss of consciousness, as produced by a bolus injection of the general anesthetic propofol to human volunteers, was accompanied by a decrease in wide-band EEG feedback connectivity from frontal cortex to parietal cortex, confirming a prediction from previous experimental studies. Interestingly, (...) frontoparietal feedback connectivity did not fully recover after the anesthetic effect wore off and the subjects first opened their eyes in response to a verbal command. Possible interpretations of the results and their implications with respect to the neural correlates of consciousness and unconsciousness are discussed. (shrink)

This paper considers prevailing environmental policy in the United States with the emphasis on liberty, markets, utilizing information, entrepreneurial discovery, and the economic analysis of political decisions. The general discussion is illustrated by the concern over global warming and policies for addressing this concern. The political incentives to confront environmental problems directly with mandates, restrictions, and subsidies ignore the power of liberty and market incentives to solve problems by fostering an impressive network of information transfer, increasing innovation, and expanding prosperity. (...) Indeed, most environmental policies systematically suppress liberty, censor the communication of information, and retard innovation and prosperity, with the result that they provide less environmental quality at greater cost than is possible. While such flawed policies might be justified in cases where pollution problems pose clear, serious, and immediate threats, we argue this is not true of global warming, and the most effective response to concerns over carbon emissions may be limiting the discretionary power of government to take direct action and rely on the indirect effects of liberty and market incentives to move us beyond the petroleum age more quickly and efficiently than will result from the direct action of government.

The tendency for emotions to be predictable over time, labelled emotional inertia, has been linked to low well-being and is thought to reflect impaired emotion regulation. However, almost no studies have examined how emotion regulation relates to emotional inertia. We examined the effects of cognitive reappraisal and expressive suppression on the inertia of behavioural, subjective and physiological measures of emotion. In Study 1 (N = 111), trait suppression was associated with higher inertia of negative behaviours. We replicated this (...) finding experimentally in Study 2 (N = 186). Furthermore, in Study 2, instructed suppressors and reappraisers both showed higher inertia of positive behaviours, and reappraisers displayed higher inertia of heart rate. Neither suppression nor reappraisal were associated with the inertia of subjective feelings in either study. Thus, the effects of suppression and reappraisal on the temporal dynamics of emotions depend on the valence and emotional response component in question. (shrink)

The questions raised by Māori identity are not static, but complex and changing over time. The ethnicity known as “Māori” came into existence in colonial New Zealand as a new, pan-tribal identity concept, in response to the trauma of invasion and dispossession by large numbers of mainly British settlers. Ideas of Māori identity have changed over the course of succeeding generations in response to wider social and economic changes. While inter-ethnic marriages and other sexual liaisons have been common (...) throughout the Māori-Pākehā relationship, the nature of such unions, and the identity choices available to their descendants, have varied according to era and social locus. In colonial families, the memory of a Māori ancestor was often deliberately suppressed, and children were encouraged to deny that part of their history and “become” European New Zealanders: a classic form of what we call “trans-ethnicity.” From a Māori perspective, the relationship with Pākehā has been marked by a series of losses: loss of land, language, social cohesion, even loss of knowledge of whakapapa. This article explores this last form of loss, which leads to “suppressed” Māori identities, and possible effects of attempting to recover such lost Māori identity rights. (shrink)

The global response to managing the spread of HIV has recently undergone a significant shift with the advent of ‘treatment as prevention’, a strategy which presumes that scaling-up testing and treatment for people living with HIV will produce a broader preventative benefit. Treatment as prevention includes an array of diagnostic, technological and policy developments that are creating new understandings of how HIV circulates in bodies and spaces. Drawing on the work of Michel Foucault, we contextualize these developments by linking (...) them to systems of governance and discursive subjectivation. The goal of this article is to problematize the growing importance of viral suppression in the management of HIV and the use of related surveillance technologies. For people living with HIV, we demonstrate how treatment-as-prevention’s emphasis on individual and collective viral load is transforming the performative dimensions of embodied risk, affect, subjectivity and sex.

Financial conflicts of interest in medical research foster deviations from research standards and evidentially lead to the suppression of research findings that are at odds with commercial interests of pharmaceutical companies. Questionable research practices prevent data from being created, made available, or given suitable recognition. They run counter to codified principles of responsible conduct of research, such as honesty, openness or respect for the law. Resulting in ignorance, misrepresentation and suspension of scientific self-correction, suppression of medical evidence in (...) its various forms is both a threat to the epistemic and the moral integrity of medical science. This paper discusses an example of the suppression of medical evidence in recent influenza research and develops a conceptual framework for the description and assessment of questionable research practices applied in research and publication processes to suppress evidence.

This research examined the role of thought suppression in the formation of mental blocks. In Experiment 1, participants were asked to generate a series of creative associates for two target words after initially suppressing a word that was semantically related to one of the two target words. Participants produced fewer responses, and experienced a greater sensation of being mentally blocked, when attempting to produce associates for the target word that was semantically related to the suppressed word. In Experiment 2, (...) participants either thought about or suppressed a series of words prior to completing a word fragment completion task. Each word either corresponded exactly to one of the word fragment solutions or resembled one of the solutions but was slightly different in its orthographic properties . Participants performed most poorly on the items for which they had initially suppressed negative primes. (shrink)

The “reproductive suppression hypothesis” states that the strong desire of adolescent girls in our culture to control their weight may reflect the operation of an adaptive mechanism by which ancestral women controlled the timing of their sexual maturation and hence first reproduction, in response to cues about the probable success of reproduction in the current situation. We develop a model based on this hypothesis and explore its behavior and evolutionary and psychological implications across a range of parameter values. (...) We use the process of model development to identify assumptions implicit in the reproductive suppression hypothesis and variables that need to be measured in order to investigate it more fully. In addition, because costs were probably associated with weight control, an important part of this analysis is the specification of situations in which the benefits of adaptive adjustment of the maturation schedule could have outweighed the costs of achieving that adjustment by slowing adolescent weight gain.

Companies will prioritize external corporate social responsibility (CSR) practices over internal ones, a phenomenon known as the corporate social responsibility gap (CSR gap). Previous studies have mostly focused on its consequences, little is known about its antecedents. We argue that such practice is illegitimate because it goes against stakeholder expectation that primary stakeholders' interests should be prioritized, but it also has potential to gain differentiation benefit for intense investment on external CSR. Drawing on compensatory orchestration logic and the three types (...) of firm legitimacy, we argue that firms that have gained high pragmatic legitimacy are more likely to engage in morally illegitimate but differentiation gaining activities such as CSR gap. Using financial distress to indicate low pragmatic legitimacy, we predict that distressed firms are inclined to practice low CSR gap. Considering the competing logics in China, we further argue that this negative relationship will be less pronounced if firms are state-owned or operating in a competitive industry. Using Chinese listed firms from 2010 to 2019 as an empirical sample, the results provide support for our arguments. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Response 2: “Pessimism of the Intellect, Optimism of the Will”Antonis BalasopoulosLet me begin with a few words on my title, which was chosen as reflecting the nature of the orientation of my work in the field of utopian studies and therefore also of my orientation toward the theme of this roundtable. As Francesca Antonini puts it in a recent essay, the phrase, which became associated with the work (...) of Antonio Gramsci though it originates in Romain Rolland, describes “the (seemingly contradictory) coexistence of a realistic description of the status quo, on the one hand, and a genuine commitment to the possibility of transforming reality, on the other.”1Anyone who has read Thomas More’s Utopia knows that Rolland’s and Gramsci’s formula very much describes that book’s bifurcation between a voice of relentless critique of what exists in Europe—and particularly in England—in More’s time (in Book 1) and a voice preoccupied with the description of an alternative, and arguably better, world (in Book 2). This bifurcation, it is equally well known, is part of the genetic material More’s book bequeathed to its successors, so that one calls a “utopia” a (mostly, though not always) literary text, where the “realistic description of the status quo” coexists with a vision arising out of a “commitment to the possibility of transforming reality”—admittedly in different admixtures and proportions of [End Page 544] the critical or negative and the anticipatory, projective or prefigurative elements. Though Ernst Bloch’s distinction between “cold” and warm” streams within Marxism is not identical to this first binary, it is certainly related to it, so that the “cold” stream is one that privileges the rational and analytical element (usually, I would propose, in relation to the part of the Marxist tradition we know as “critique of political economy”), while the “warm stream” is one that rather foregrounds that which relates to affect, to desire, hope, or fidelity to the transformative project (these are frequently correlated to those elements of Marxism that correspond to its also being a political and philosophically imbued creed).2 What follows here, then, explores the implications of the dialectical interplay between these two sets of oppositions—and hopefully justifies such insistence on dialectic itself.3To the extent that I can see, the basic themes and areas of concentration in my colleagues’ essays involve decolonizing utopian studies as a project; addressing, in that connection, the heterogeneity of utopianisms that emerge out of a number of marginalized subjectivities; the provenance of the questions of ecology, sustainability, animal life for the present and future of utopian studies (and to some degree, for utopianism’s past); and finally, the question of utopian forms of social activism and therefore also the search for spaces beyond the walls of academic insularity. These are important and largely interconnected questions, but I am afraid I will only have the space to touch on them briefly and sketchily here.In her cogent and multifaceted intervention, Caroline Edwards begins her reflections on the task of decolonizing utopian studies by noting the high investment of fin-de-siècle utopian fiction in notions of industrial progress, noting that such notions have involved “lasting damage” for “Black writers, artists, and thinkers.” Within this framework, she evokes Joseph R. Winters’s argument that “modern notions of progress and freedom are inherently flawed,” since they are founded on the oppressive traditions of capitalism and colonialism. In turn, this leads to an argument against the teleological futurism of most nineteenth-century utopias and in support of the deconstruction of “the idea of historical progress unfolding in Hegelian dialectical stages.” What is to replace this is a hauntological (after Derrida) conception of the relation between the present and the past, for which “the present is always a site of potential breaks and ruptures that can signify both dislocation and pain as well as novelty and possibility.” In a similar vein, Heather Alberro questions the teleological futurism of an earlier tradition of utopia, evoking Laurence Davis’s observation on the importance of [End Page 545] “neglected or suppressed possibilities for qualitatively better forms of life” within the “Now.” The desideratum is, again...

The concept of “moral responsibility” has almost always been defined in relation to a certain idea of metaphysical freedom and to a conception of the physical world. So, classically, for indeterminist thinkers, human beings are free and therefore responsible, if their choices are not defined by a previous state of the world but derive from an autonomous selection among a set of alternatives. Differently, for the majority of determinist philosophers , the only form of freedom we need has to be (...) identified with freedom of the conduct, considered as opposite to any form of coercion. Some argue that, given the truth of determinism and the related suppression of concepts such as “guilt” and “praise”, or “merit” and “demerit”, morality could survive just as a utilitarian tool, even though this seems to be in conflict with our deepest feelings and practices. Considering some revisionist approaches of moral responsibility in connection with classical positions , I will reconstruct some of the attempts to release responsibility from the thematisation of freedom, exploring the possibility of redefining it as an independent concept. My conclusion is that the focus on the choice-action process and on the characteristics of the “self”, avoiding reference to alternative scenarios, could be a good starting point for elaborating a conception of what really counts for our moral life – even though, in the end, this could entail the abandonment of the traditional concept of responsibility itself.

Insect endoparasitoids are able to circumvent the defense reactions of their habitual hosts. In a hymenopteran wasp species, virus‐like particles, found on the egg surface are responsible for the protection against the encapsulation reaction of the host caterpillar. Some of the particle proteins are structurally and probably functionally related to host protein(s). Biological properties of some of the host proteins suggest that they might be involved in the insect defense reaction.

Art therapy encourages the use of art materials to express feelings and thoughts in a supportive environment. Art materials differ in fluidity and are postulated to thus differentially enhance emotional response (the more fluid the material the more emotion). Yet, to the best of our knowledge, this assumption has not been empirically tested. The current study aimed to examine the emotional and physiological responses to art making with different art materials. We were particularly interested in vagal activity, indexed by (...) heart rate variability (HRV), because of its association with numerous health related outcomes. In this study, fifty adults (mean age 33 ± 10.27 years, 52% males) participated in a repeated measures experiment, in which they were requested to draw with three art materials (order randomized) differing in their level of fluidity (pencil, oil-pastels and gouache paint) intermittent with periods of music. We measured the emotional response to art making with each material using a self-report measure and matrices of HRV using a wearable electrocardiogram (ECG) device. We calculated two indices of HRV, one indicative of parasympathetic nervous system (PNS) activity, and one indicative of sympathetic nervous system (SNS) activity. Art making with gouache paint and oil pastels resulted in improved positive mood, while pencil did not. Art making explained approximately 35% of the variability in parasympathetic reactivity, which may indicate changes in emotional regulation processes during the art-making task. Yet, fluidity was not sufficient to explain the reaction to art-making. Surprisingly, the largest suppression of PNS and augmentation of the SNS occurred during art-making with oil-pastels and not with Gouache. Moreover, PNS and SNS reactivity to oil-pastels were related to emotional valance, which may point to emotional engagement. We can conclude that art-making with oil-pastels, first created in Japan in 1924 to increase self-expression of students, results in a unique emotional and physiological responses. These findings might be explained by the enhanced tactile experience of art-making with oil-pastels along with their relative fluidity, triggering an arousal pattern. Further studies that take the format and presentation of the materials as well as the content of the artwork, into account, are needed. (shrink)

The COVID-19 crisis has forced a difficult trade-off between limiting the health impacts of the virus and maintaining economic activity. Welfare economics offers tools to conceptualize this trade-off so that policy-makers and the public can see clearly what is at stake. We review four such tools: the Value of Statistical Life (VSL); the Value of Statistical Life Years (VSLYs); Quality-Adjusted Life-Years (QALYs); and social welfare analysis, and argue that the latter are superior. We also discuss how to choose policies that (...) differentially affect people’s wellbeing. We argue in favor of evaluating policies using a Social Welfare Function (SWF), which evaluates the possible distributions of wellbeing across individuals that may result from a policy. Such a function, we argue, should regard increases in the wellbeing of the less well-off as especially valuable. We then use a model to illustrate how such a framework can help evaluate two broad policy types in response to the pandemic: eradication of the virus, and more lenient control of the spread. Our model reveals how such evaluations depend on many empirical facts but also on key value judgments about the relative importance of health and on the extent of special concern for the worse off. The purpose of this brief is not to make precise recommendations, as conditions vary widely across countries and over time, but to provide a methodology. (shrink)

Major contributions emanating from Sagvolden et al.'s theory include elucidation of the role in attention-deficit/hyperactivity disorder (ADHD) of temporal information processing, social learning, and response extinction learning. Key issues include a need for clearer explanation of the relative role of impulsivity versus response suppression/inhibition in the dual process model, and delineation of genotype-environment correlations versus interactions in the social and experiential mechanisms posited.

Both classical psychophysical work and recentfunctional imaging studies have suggested acritical role for the primary visual cortex(V1) in resolving the perceptual ambiguitiesexperienced during binocular rivalry. Here weexamine, by means of single-cell recordings andoptical imaging of intrinsic signals, thespatial characteristics of suppression elicitedby rival stimuli in cat V1. We find that the interocular suppression field of V1 neuronsis centred on the same position in space and isslightly larger (by a factor of 1.3) than theminimum response field, measured through (...) thesame eye. Suppression is always strongest at asingle position corresponding very closely tothe centre of the classical receptive field,and reduces responses through the other eye byup to 90% but typically around 40%. Thespatial pattern of interocular suppression, asrevealed by optical imaging, closely matchesthe cortical representation of the stimulus,which is being suppressed, both in terms of itsorientation and the eye of origin. Theseresults indicate that interocular suppressionis directly related to the functionalarchitecture of V1; it is probably caused bydirect inhibitory interactions betweenneighbouring cortical columns of oppositeocular dominance.

Reproduction places severe demands on the energy metabolism in human females. When physical work entails higher energy expenditure, not enough energy will be left for the support of the reproductive processes and temporal suppression of the reproductive function is expected. While energy needed for reproduction may be obtained by increases in energy intake, utilization of fat reserves, or reallocation of energy from basal metabolism, several environmental or physiological constraints render such solutions unlikely. For human ancestors increases in energy intake (...) were limited by availability of food, by labor of food preparation and by metabolic ceilings to energy assimilation. Energy stored as fat may support only a fraction of the requirements for reproduction (especially lactation). Effects of intense physical activity on basal metabolism may also interfere with fat accumulation during pregnancy. Finally, the female physiology may experience demands on increasing the basal metabolism as a consequence of physical activity and, at the same time, on decreasing the basal metabolism, when energy to support the ongoing pregnancy or lactation is inadequate. The resulting metabolic dilemmas could constitute a plausible cause for the occurrence of reproductive suppression in response to physical activity. It is, therefore, likely that allocating enough energy to the reproductive processes during periods when energy expenditure rises may be difficult due to physiological and bioenergetic constraints. Females attempting pregnancy in such conditions may compromise their lifetime reproductive output. A reproductive suppression occurring in low energy availability situations may thus represent an adaptive rather then a pathological response. (shrink)

Over-general autobiographical memory retrieval is characterized by retrieval of categoric autobiographical memories. According to the CarFAX model, this tendency may result from avoidance which functions to protect the person against recalling details of upsetting memories. This study tested whether avoidance strategies impact on the ability to retrieve specific autobiographical memories. Healthy participants watched a negative video clip and were instructed to either suppress any thought , suppress any feeling , or think and feel naturally in response to the video. (...) Participants then completed the Autobiographical Memory Test. Participants engaging in either thought suppression or emotional inhibition retrieved fewer categoric autobiographical memories than controls. These findings challenge the affect regulation component of the CarFAX model insofar as they suggest that regulatory strategies that aim to reduce awareness of adverse emotional memories do not necessarily lead to increased recall of categoric autobiographical memories.
