Anxiety shifts visual attention and perceptual mechanisms, preparing oneself to detect potentially threatening information more rapidly. Despite being demonstrated for threat‐related social stimuli, such as fearful expressions, it remains unexplored if these effects encompass other social cues of danger, such as aggressive gestures/actions. To this end, we recruited a total of 65 participants and asked them to identify, as quickly and accurately as possible, potentially aggressive actions depicted by an agent. By introducing and manipulating the occurrence of electric shocks, (...) we induced safe and threatening conditions. In addition, the association between electric shocks and aggression was also manipulated. Our result showed that participants have improved sensitivity, with no changes to criterion, when detecting aggressive gestures during threat compared to safe conditions. Furthermore, drift diffusion model analysis showed that under threat participants exhibited faster evidence accumulation toward the correct perceptual decision. Lastly, the relationship between threat source and aggression appeared to not impact any of the effects described above. Overall, our results indicate that the benefits gained from states of anxiety, such as increased sensitivity toward threat and greater evidence accumulation, are transposable to social stimuli capable of signaling danger other than facial expressions.

Almost four decades have passed since Dutton and Aron published their classic article in JPSP in which they present the results of three studies. According to interpretations of the results done by the authors, the suffi cient condition of obtaining the effect of increased sexual attraction toward the object - which must be present shortly after or while waiting to become an aversive stimulus - is the induction in the subjects of a strong autonomic arousal. This can be done via (...) crossing a high suspended bridge or anticipating the receipt of strong electric shocks. However, the results of reanalysis do not allow such a conclusion. In the article the author presents the results of secondary analysis and lists methodological, theoretical and interpretative incoherences. (shrink)

Pain and reward have crucial roles in determining human behaviors. It is still unclear how pain influences different stages of reward processing. This study aimed to assess the physical pain’s impact on reward processing with event-related potential method. In the present study, a flash sale game was carried out, in which the participants were instructed to press a button as soon as possible to obtain the earphone after experiencing either electric shock or not and finally evaluated the outcome (...) of their response. High-temporal-resolution electroencephalogram data were simultaneously recorded to reveal the neural mechanism underlying the pain effect. The ERP analyses revealed that pain affected the feedback processing reflected by feedback-related negativity and P300. Specifically, participants in the nopain situation exhibited greater FRN discrepancy between success and failure feedbacks relative to that in the pain situation. Moreover, the P300 amplitude was enhanced in the nopain condition compared to the pain condition regardless of the feedback valence. These results demonstrate that the pain reduced the sensitivity to the reward valence at the early stage and weakened the motivational salience at the late stage. Altogether, this study extends the understanding of the effect of pain on reward processing from the temporal perspective under a purchasing situation. (shrink)

The paper concludes the argument that certain aesthetic objects conduce to a feeling of radical contingency, and to an openness to St Thomas's Third Way proof for the existence of God. Much is conceded to the late Mr Gershon Weiler's criticism of an earlier discussion. The upshot is (a) that Necessary Being as converse of radical contingency may be an Aesthetic Idea/Sublime of Kant's kind, and (b) that without the ‘I AM that I am’, it is empty. The ‘inference’ from (...) radical contingency to Necessary Being may function as George Eliot thought Wit to function, intellectually/aesthetically. (shrink)

This paper explores the relationship between psychology and neurobiology in the context of cognitive science. Are the sciences that constitute cognitive science independent and theoretically autonomous, or is there a necessary interaction between them? I explore Fodor's Multiple Realization Thesis (MRT) which starts with the fact of multiple realization and purports to derive the theoretical autonomy of special sciences (such as psychology) from structural sciences (such as neurobiology). After laying out the MRT, it is shown that, on closer inspection, the (...) argument is either circular or self-undermining--the argument either assumes the very autonomy it seeks to demonstrate or the concluded autonomy is contradicted by the theoretical interdependence invoked by the premises of the argument. Next, I explore a concrete example of multiple realization in the explanation of animal behavior: the convergent evolution of jamming avoidance behaviors in three genera of weakly electric fish. Contrary to the image painted by the MRT, the work on these animals involves a high degree of interaction between the various levels of investigation. The fact that our understanding of electric fish behavior involves functional theories and multiple realization without the kind of disunified science that is supposed to follow from such a situation indicates that the mere fact of multiple realization cannot be the basis for an autonomous psychology.

The 1790 Fête de la fédération in the early French Revolution evoked the memory of the taking of the Bastille while tamping down on the simmering social forces that had erupted on 14 July 1789. How to do both? As an official architect put it, through the festival, ‘the sentiment of each becomes the sentiment of all by a kind of electrification, against which even the most perverse men cannot defend themselves’. This paper argues that a new language of revolutionary (...) electricity came into being with the French Revolution. It argues that revolutionaries drew upon concepts of medical electricity developed in the 1780s to analogize the literal electricity of the ether to the revolutionary electricity of collective political sentiment. Though historians have associated electricity with radical politics, this paper argues that in the hands of bureaucrats and festival planners, electricity entered revolutionary discourse as a powerful mechanism for exercising authority and control over an unruly revolutionary public.

There are two aims of this paper: (1) to explore the affective dimensions of moral shock and how it relates to normative marginalization of those furthest from dominant society, but also, more specifically; (2) to articulate the trans experience of constantly being under moral attack because the dominant “world” normatively defines you out of existence. Toward these ends, I build on Katie Stockdale’s recent work on moral shock, arguing that moral shock needs to be contextualized to “worlds” (...) of sense to understand how marginalized people affectively experience shocking events. My focus is the trans experience of moral shock due to the way trans people are positioned outside of dominant society, creating the conditions to experience cyclical, chronic shock. These affective conditions point to a collective responsibility to ease the affective stress that the most marginalized experience. (shrink)

Investigations with electrometers in the 1770s led Volta to envision mobile charge in electrical conductors as a compressible fluid. A pressure-like condition in this fluid, which Volta described as the fluid’s “effort to push itself out” of its conducting container, was the causal agent that makes the fluid move. In this paper I discuss Volta’s use of analogy and imagery in model building, and compare with a successful contemporary conceptual approach to introducing ideas about electric potential in instruction. The (...) concept that today is called “electric potential” was defined mathematically by Poisson in 1811. It was understood after about 1850 to predict the same results in conducting matter as Volta’s pressure-like concept—and to predict electrostatic effects in the exterior space where Volta’s concept had nothing to say. Complete quantification in addition to greater generality made the mathematical concept a superior research tool for scientists. However, its spreading use in instruction has marginalized approaches to model building based on the analogy and imagery resources that students bring into the classroom. Data from pre and post testing in high schools show greater conceptual and confidence gains using the new conceptual approach than using conventional instruction. This provides evidence for reviving Volta’s compressible fluid model as an intuitive foundation which can then be modified to include electrostatic distant action. Volta tried to modify his compressible fluid model to include distant action, using imagery borrowed from distant heating by a flame. This project remained incomplete, because he did not envision an external field mediating the heating. However, pursuing Volta’s strategy of model modification to completion now enables students taught with the new conceptual approach to add distant action to an initial compressible fluid model. I suggest that a partial correspondence to the evolving model sequence that works for beginning students can help illuminate Volta’s use of intermediate explanatory models. (shrink)

Modern empirical macroeconomic models, known as structural autoregressions (SVARs) are dynamic models that typically claim to represent a causal order among contemporaneously valued variables and to merely represent non-structural (reduced-form) co-occurence between lagged variables and contemporaneous variables. The strategy is held to meet the minimal requirements for identifying the residual errors in particular equations in the model with independent, though otherwise not directly observable, exogenous causes (“shocks”) that ultimately account for change in the model. In nonstationary models, such shocks accumulate (...) so that variables have discernible trends. Econometricians have conceived of variables that trend in sympathy with each other (so-called “cointegrated variables”) as sharing one or more of these unobserved trends as a common cause. It is possible for estimates of the values of both the otherwise unobservable individual shocks and the otherwise unobservable common trends to be backed-out of cointegrated systems of equations. The issue addressed in this paper is whether and in what circumstances these values can be regarded as observations of real entities rather than merely artifacts of the representation of variables in the model. The issue is related, on the one hand, to practical methodological problems in the use of SVARs for policy analysis—e.g., does it make sense to estimate of shocks or trends in one model and then use them as measures of variables in a conceptually distinct model? The issue is also related to debates in the philosophical analysis of causation—particularly, whether we are entitled, as assumed by the developers of Bayes-net approaches, to rely on the causal Markov condition (a generalization of Reichenbach’s common-cause condition) or whether cointegration generates a practical example of Nancy Cartwright’s “byproducts” objection to the causal Markov condition.
