Investigating the influence of perception on the control of visually guided action typically involves controlled experimentation within the laboratory setting. When appropriate, however, behavioral research of this nature may benefit from the use of methods that allow for remote data collection outside of the lab. This study tested the feasibility of using remote data collection methods to explore the influence of perceived target size on visually guided cursor movements using the Ebbinghaus illusion. Participants completed the experiment remotely, using the trackpad (...) of their personal laptop computers. The task required participants to click on a single circular target presented at either the left or right side of their screen as quickly and accurately as possible, or to emphasize speed or accuracy. On each trial the target was either surrounded by small or large context circles, or no context circles. Participants’ judgments of the targets’ perceived size were influenced by the illusion, however, the illusion failed to produce differences in click-point accuracy or movement time. Interestingly, the illusion appeared to affect participants’ movement of the cursor toward the target; more directional changes were made when clicking the Perceived Large version of the illusion compared to the Perceived Small version. These results suggest the planning of the cursor movement may have been influenced by the illusion, while later stages of the movement were not, and cursor movements directed toward targets perceived as smaller required less correction compared to targets perceived as larger.

Scanlon (2008) has argued that his theory of permissibility (STP) has more explanatory power than the Doctrine of Double Effect (DDE). I believe this claim is wrong. Borrowing Michael Walzer’s method of inquiry, I will evaluate the explanatory virtue of these accounts by their understanding of actual moral intuitions originated in historical cases. Practically, I will evaluate these accounts as they explain cases of hostage crises. The main question in this context is: is it permissible that nation-states act with military (...) force in order to liberate hostages, even if those actions put the lives of the hostages at risk? The first part of this paper has an operative reconstruction of the relevant theories. In the second section, two cases of hostage crises will be considered: the Moscow theater hostage crisis of 2002, and the Jaque Operation, which occurred in Colombia in 2008. Additionally, it will be shown that DDE explains these cases better than STP. Finally, this paper offers a critical analysis of Scanlon’s account of the explanatory power of both STP and DDE.

Since the pioneering work of [Aglioti, S., DeSouza, J. F., & Goodale, M. A. . Size-contrast illusions deceive the eye but not the hand. Current Biology, 5, 679–685] visual illusions have been used to provide evidence for the functional division of labour within the visual system—one system for conscious perception and the other system for unconscious guidance of action. However, these studies were criticised for attentional mismatch between action and perception conditions and for the fact that grip size is not (...) determined by the size of an object but also by surrounding obstacles. Stoettinger and Perner [Stoettinger, E., & Perner, J., . Dissociating size representations for action and for conscious judgment: Grasping visual illusions without apparent obstacles. Consciousness and Cognition, 15, 269–284] used the diagonal illusion controlling for the influence of surrounding features on grip size and bimanual grasping to rule out attentional mismatch. Unfortunately, the latter objective was not fully achieved. In the present study, attentional mismatch was avoided by using only the dominant hand for action and for indicating perceived size. Results support the division of labour: Grip aperture follows actual size independent of illusory effects, while finger-thumb span indications of perceived length are clearly influenced by the illusion.

We previously showed that the illusory sense of ownership and agency over a moving body in immersive virtual reality can trigger subjective and physiological reactions on the real subject’s body and, therefore, an acute improvement of cognitive functions after a single session of high-intensity intermittent exercise performed exclusively by one’s own virtual body, similar to what happens when we actually do physical activity. As well as confirming previous results, here, we aimed at finding in the elderly an increased improvement (...) after a longer virtual training with similar characteristics. Forty-two healthy older subjects completed a parallel-group randomized controlled trial including an adapted version of the virtual training previously used: while sitting, participants observed the virtual body in a first-person perspective or a third-person perspective performing 20 min of virtual high-intensity intermittent exercise. This was repeated twice a week for 6 weeks. During the vHIE, we measured the heart rate and administered questionnaires to evaluate illusory body ownership and agency. Before the beginning of the intervention, immediately after the first session of vHIE, and at the end of the entire intervention, we evaluated the cognitive performance at the Stroop task with online recording of the hemodynamic activity over the left dorsolateral prefrontal cortex. While we confirm previous results regarding the virtual illusion and its physiological effects, we did not find significant cognitive or neural improvement immediately after the first vHIE session. As a novelty, in the 1PP group only, we detected a significant decrease in the response time of the Stroop task in the post-intervention assessment compared to its baseline; coherently, we found an increased activation on left dorsolateral prefrontal cortex after the entire intervention. While the current results strengthen the impact of the virtual full-body illusion and its physiological consequences on the elderly as well, they might have stronger and more established body representations. Perhaps, a longer and increased exposure to those illusions is necessary to initiate the cascade of events that culminates to an improved cognitive performance. (shrink)

Prominent scientists and policymakers assert with confidence that there is no scientific controversy over the health effects of genetically modified organisms —that genetically modified crops currently in commercial use and those yet to be commercialized are inherently safe for human consumption and do not have to be tested. Those who disagree are cast as “GMO deniers.” This article examines scientific reviews and papers on GMOs, compares the findings of professional societies, and discusses the treatment of scientists who have reported (...) adverse effects in animal feeding experiments. This article concludes by exploring the role that politics and corporate interests have had in distorting an honest inquiry into the health effects of GMO crops. (shrink)

In illusory line motion, presentation of a cue is followed by presentation of a nearby stationary line, and the line is perceived to “unfold,” “expand,” or “extend” away from the cue. Effects of the allocation of attention regarding where the cue or the line would be presented were measured in three experiments, and ratings of relative velocity and relative strength of illusory motion were collected. Findings included (a) relative velocity and relative strength decreased with increases in SOA (...) from 50 to 450 ms, (b) relative velocity and relative strength were not influenced by whether illusory motion moved from one end of the line to the other or from both ends toward the middle of the line, (c) increased uncertainty regarding where the line would appear did not influence relative velocity or relative strength, and (d) valid pre-cues regarding the location of a cue resulted in faster relative velocity than did invalid pre-cues, but pre-cue validity did not influence relative strength. Implications of these findings for the relationship of such illusory motion and attention (e.g., divided attention, shifts in attended location) are considered. (shrink)

Wagering contingent on a previous decision, or post-decision wagering, has recently been proposed to measure conscious awareness. Whilst intuitively appealing, it remains unclear whether economic context interacts with subjective confidence and how such interactions might impact on the measurement of awareness. Here we propose a signal detection model which predicts that advantageous wagers placed on the identity of preceding stimuli are affected by loss aversion, despite stimulus visibility remaining constant. This pattern of predicted results was evident in a psychophysical task (...) where we independently manipulated perceptual and economic factors. Changes in wagering behaviour induced by changes in wager size were largely driven by changes in criterion, consistent with the model. However, for near-threshold stimuli, a reduction in wagering efficiency was also evident, consistent with an apparent but potentially illusory decrease in awareness of the stimulus. These findings challenge an assertion that post-decision wagering provides a direct index of subjective awareness. (shrink)

Reflectance physicalism only provides a partial picture of the ontology of color. Byrne & Hilbert’ account is unsatisfactory because the replacement of reflectance functions by productance functions is ad hoc, unclear, and only leads to new problems. Furthermore, the effects of color contrast and differences in illumination are not really taken seriously: Too many “real” colors are tacitly dismissed as illusory, and this for arbitrary reasons. We claim that there cannot be an all-embracing ontology for color.

The algorithms and processes of modern technologies affect almost all aspects of our lives. No human being is making individual subjective choices in each, or any, instance of these processes—all cases are treated with perfect technological indifference. Hence, a commonsense assumption about the technologies we interact with, and the algorithms many of them implement, is that they are neutral and impartial. Of course, this is simply not the case. As has been extensively documented and discussed, bias exists in all facets (...) of technology, from how and why it was first conceived and then developed to its inputs, processes and outputs. I examine instances of technological bias in visual representation and criminal justice technologies, and argue that they produce, among other epistemic concerns, a form of hermeneutical injustice by means of obstructing the deployment of the necessary and otherwise available hermeneutical resources needed to accurately understand these technologies and their effects. Such epistemic harm is inevitable, unless the relationship between our human biases and the technological processes produced by us is made explicit and significantly rethought. (shrink)

There is a continuing debate in the field of perceptual organization as to whether the locus of global processing is early or late perceptual, as previous studies have yielded contrary results. The conducted behavioural study explored this issue with the paradigm of collating global processing with other process of perceptual organization, namely illusory contours processing. Interaction between these two processes of perceptual organization would indicate that global processing has an early perceptual locus, whereas the lack of such interaction would (...) suggest the late perceptual locus of global processing. In experiment 1, the effect of global dominance was obtained with the use of a compound figure composed of geometrical shapes with real edges. Results showed that the processing of the figure at the global level was faster and that it disrupted the processing of the figures from the local level. In experiment 1b, the compound figure was composed of local geometrical shapes generated with the use of the line-end induced illusory contours. Local elements with illusory contours did not affect the processing of the hierarchical structure and the effect of global precedence occurred without any changes. In experiment 2a, a global advantaged effect within a compound figure with local elements with real edges was obtained in the paradigm of attention divided between levels of the hierarchical structure. When illusory contours of local elements of a compound figure were introduced to this paradigm, this again had no effect on the perceptual global advantage. The results demonstrate the lack of interaction between global processing and illusory contour processing, indicating that the locus of global processing is rather late perceptual. (shrink)

Interaction systems with gesture-based touchless inputs are becoming more common. Nevertheless, perceptual properties of the visual feedback used in the system have not been well documented. We investigated whether the speed of motion shown in visual feedback used in gesture-based touchless inputs could be a cue for the heaviness sensation of an object even when other incidental cues, such as changes in object size and spatial consistencies in direction between gestures and feedback, were eliminated from the stimuli. Participants were asked (...) to make a gesture to grasp and raise/lower disks shown on a horizontal display. The disk’s diameter changed in accordance with the vertical position of the participant’s hand. The results showed that the rate of change in diameter determined the heaviness sensation. When the disks were replaced with concentric gratings having sinusoidal radial intensity and thus the cue of size change was eliminated from the stimuli, the heaviness sensation was dependent on the speed of phase shift in the grating. It was also found that spatial consistency between the direction of gestures and phase shift was not a critical condition for the heaviness sensation. Finally, the speed of motion served as a critical determinant of the heaviness sensation even when another visual feature was modulated in a single session, which indicates that the effect of the speed of motion on the heaviness sensation was unlikely due to demanded characteristics. The results indicate that the heaviness sensation for visual feedback of gesture-based touchless inputs is based purely on the speed of the visual feedback motion. (shrink)

Comparisons between modally and amodally completed regions show that perceptual filling-in is not merely the ignoring of absences. Illusory filled-in colour arises for modal completion, but not for amodal completion in comparable displays. We find that attention spreads automatically to modally but not amodally completed regions from their inducers, revealing a functional effect of filled-in colour.

Recent research has begun to investigate sensory processing in relation to nonclinical variation in traits associated with the autism spectrum disorders (ASD). We propose that existing accounts of autistic perception can be augmented by considering a role for individual differences in top-down expectations for the precision of sensory input, related to the processing of state-dependent levels of uncertainty. We therefore examined ASD-like traits in relation to the rubber-hand illusion: an experimental paradigm that typically elicits crossmodal integration of visual, tactile, and (...) proprioceptive information in an unusual illusory context. Individuals with higher ASD-like traits showed reduced effects of the rubber-hand illusion on perceived arm position and reach-to-grasp movements, compared to individuals with lower ASD-like traits. These differences occurred despite both groups reporting the typical subjective experience of the illusion concerning visuotactile integration and ownership for the rubber hand. Together these results suggest that the integration of proprioceptive information with cues for arm position derived from the illusory context differs between individuals partly in relation to traits associated with ASD. We suggest that the observed differences in sensory integration can be best explained in terms of differing expectations regarding the precision of sensory estimates in contexts that suggest uncertainty.

Transcranial magnetic stimulation (TMS) of the visual cortex can induce phosphenes as can non-diagnostic ultrasound, the latter while participants have closed their eyes during Stimulation. Here we sought to study potential alteration of a visual target (a white crosshair) due to application of diagnostic ultrasound to the visual cortex. We applied a randomized series of actual or sham diagnostic ultrasound to the visual cortex of healthy participants while they stared at a visual target, with the ultrasound device placed where TMS (...) elicited phosphenes. These participants observed percepts 7 out of 10 times, consisting of extra or extensions of lines relative to the original crosshair, and additional colors. Observation of a percept occurred an average of 53.7 +/- 2.6% of the time over the course of the experiment for these participants. In contrast, 7 out of 10 participants exposed to sham-only diagnostic ultrasound observed comparable percepts an average of 36.3 +/ 1.9% of the time, a statistically significant difference (p < 0.00001). Moreover, on average, participants exposed to a combination of sham and actual ultrasound reported a net increase of 47.9 percentage points in the likelihood that they would report a visual effect by the end of the experiment. Our experiment demonstrated that a random combination of sham-only and actual diagnostic ultrasound applied to the visual cortex of participants increased the likelihood that they would observe visual effects, but not the type of effects, with that likelihood increasing over the course of the experiment. From this we conclude that repeated exposures by diagnostic ultrasound made the visual cortex more responsive to stimulation of their visual cortex by the visual target. These observations, consistent with other’s observation of effects of diagnostic ultrasound stimulation of human motor cortex and amygdala, as well as the FDA approved nature of diagnostic ultrasound, may lead to increased study of diagnostic ultrasound applied to human brain.

Size perception of visual objects is highly context dependent. Here we report a novel perceptual size illusion that the self-face, being a unique and distinctive self-referential stimulus, can enlarge its perceived size. By using a size discrimination paradigm, we found that the self-face was perceived as significantly larger than the other-face of the same size. This size overestimation effect was not due to the familiarity of the self-face, since it could be still observed when the self-face was directly compared with (...) a famous face. More crucially, such illusion effect could be extended to a new cartoon face that was transiently associated with one's own face and could also exert further contextual influences on visual size perception of other objects. These findings together highlight the role of self-awareness in visual size perception and point to a special mechanism of size perception tuned to self-referential information. (shrink)

This article presents psychophysical evidence that the Kanizsa Square does not produce an 'object superiority effect' previously reported in similar Gestalt configurations. Implications of the findings for Gestalt theory are addressed.

We argue that one can explain why the influence of illusions decreases during a movement without assuming that different visual representations are used for planning and control. The basis for this is that movements are guided by a combination of correctly perceived information about certain attributes (such as a target's position) and illusory information about other attributes (such as the direction of motion). We explain how this can automatically lead to a decreasing effect of illusions when hitting discs that (...) move in an illusory direction, and when grasping objects of which the apparent size or orientation has been changed by an illusion.

A mechanistic explanation is a desired outcome in many studies of perception. Such explanations require discovering the processes that contribute to the realization of a perceptual phenomenon at different levels of information processing. The present analysis aims at investigating the obstacles to develop such mechanistic explanations and their potential solutions in the context of psychopathology. Geometric-Optical Illusions (GOIs) are among perceptual phenomena that have been studied to understand psychopathology in various clinical populations. In the present analysis, the GOIs will be (...) discussed as a methodological tool in the investigation of the mechanistic approach to understanding perception in such populations. I will argue that the fact that most such studies are mainly focused on the investigation of susceptibility to GOIs can only lead to classifying such phenomena or to reporting some correlations between different aspects of such phenomena with certain brain activities, without formulating a mechanistic explanation. The investigation of the variables that mediate perceptual phenomena at earlier stages of information processing is required for the formulation of such explanations. Thus, the objective of the present analysis is twofold: 1) showing how ignoring such variables have prevented the formulation of mechanistic explanations of responses to GOIs in clinical populations, such as schizophrenia and autism, 2) analyzing the methodological aspects of an effective approach in which a top-down guidance based on phenomenological insights (the first-person data) along with the insights provided by the existing theories help overcome obstacles in developing mechanistic explanations of GOIs.

In psychophysical experiments, the use of a psychophysical procedure of brightness/darkness cancellation shed light on interactions between spatial arrangement and figure–ground contrast in the perceptual filling in of achromatic and colored surfaces.Achromatic and chromatic Kanizsa squares with varying contrast, contrast polarity, and inducer spacingwere used to test how these factors interact in the perceptual filling in of surface brightness or darkness. The results suggest that the neuronal processing of surfaces with apparent contrast, leading to figure–ground segregation (i.e., perceptual organization), is (...) governed by mechanisms that integrate both luminance contrast and spatial information carried by the inducing stimuli, while discarding information on contrast polarity or color. The findings are discussed in relation to earlier observations on brightness assimilation and contrast. They support theories of nonantagonistic neural mechanisms suppressing local contrast or color signs in brightnessbased figure–ground percepts. Such mechanismsmight be necessary to cancel potentially conflicting polarities in geometricallycomplex visual stimuli so that perceptual filling in resulting in the most plausible representation of figure and ground can be achieved.

Visual illusions provide important evidence for the co-existence of unconscious and conscious representations. Objects surrounded by other figures are consciously perceived as different in size, while the visuo-motor system supposedly uses an unconscious representation of the discs’ true size for grip size scaling. Recent evidence suggests other factors than represented size, e.g., surrounding rings conceived as obstacles, affect grip size. Use of the diagonal illusion avoids visual obstacles in the path of the reaching hand. Results support the dual representation theory. (...) Grip size scaling follows actual size independent of illusory effects, which clearly bias conscious perception in direct comparisons of lengths and in finger-thumb span indications of perceived length.

Perceived size is a function of viewing distance, retinal images size, and various contextual cues such as linear perspective and the size and location of neighboring objects. Recently, we demonstrated that illusion magnitudes of classic visual size illusions may be greatly enhanced or reduced by adding dynamic elements. Specifically, a dynamic version of the Ebbinghaus illusion (classically considered a “size contrast” illusion) led to a greatly enhanced illusory effect, whereas a dynamic version of the Corridor illusion (a “size constancy” (...) illusion) led to a greatly diminished illusory effect. Although these differences may arise from the different processes underlying these illusions (size contrast vs. size constancy), the dynamic variants we tested in our previous work also differed in the nature of the dynamic elements; specifically, whereas the Dynamic Ebbinghaus included a moving target and inducers that changed size and position, the Dynamic Corridor only included a moving target on a static background. Here, we explore further dynamic versions of the Ebbinghaus illusion and the Corridor and Ponzo illusions by separately manipulating three types of dynamic elements: target motion, context translation, and dynamic changes in context. Across five experiments examining 21 dynamic illusory configurations, adding target motion or a dynamically changing context separately resulted in little-to-no illusory effect. In contrast, the combination of target motion and a dynamically changing context led to a robust size illusion, consistent with an interactive effect. However, illusory effects that exceeded the matched classic, static illusory configuration were only observed for the dynamic versions of the Ebbinghaus illusion and the Revealed Ponzo illusions, in which the contextual elements changed size. We conclude that the combination of target motion and a dynamically changing context are necessary to produce dynamic size illusions, but that enhancement above and beyond static illusions may be largely specific to size contrast effects. Our results have important implications for the integration of motion signals, a ubiquitous environmental stimulus, in the perception of object size. (shrink)

Neurophysiological investigations of the visual system by way of single-cell recordings have revealed a hierarchical architecture in which lower level areas, such as the primary visual cortex, contain cells that respond to simple features, while higher level areas contain cells that respond to higher order features apparently composed of combinations of lower level features. This architecture seems to suggest a feed-forward processing strategy in which visual information progresses from lower to higher visual areas. However there is other evidence, both neurophysiological (...) and phenomenal, that suggests a more parallel processing strategy in biological vision, in which top-down feedback plays a significant role. In fact Gestalt theory suggests that visual perception involves a process of emergence, i.e. a dynamic relaxation of multiple constraints throughout the system simultaneously, so that the final percept represents a stable state, or energy minimum of the dynamic system as a whole. A Multi-Level Reciprocal Feedback (MLRF) model is proposed to resolve the apparently contradictory concepts, by proposing a hierarchical visual architecture whose different levels are connected by bi-directional feed-forward and feedback pathways, where the computational transformation performed by the feedback pathway between levels in the hiararchy is a kind of inverse of the transformation performed by the corresponding feed-forward processing stream. This alternative paradigm of perceptual computation accounts in general terms for a number of visual illusory effects, and offers a computational specification for the generative, or constructive aspect of perceptual processing revealed by Gestalt theory.

In this study, we explored the time and space relationship according to two different spatial codings, namely, the left/right extension and the reachability of stimulus along a near/far dimension. Four experiments were carried out in which healthy participants performed the time and spatial bisection tasks in near/far space, before and after short or long tool-use training. Stimuli were prebisected horizontal lines of different temporal durations in which the midpoint was manipulated according to the Muller-Lyer illusion. The perceptual illusory (...) class='Hi'>effects emerged in spatial but not temporal judgments. We revealed that temporal and spatial representations dynamically change according to the action potentialities of an individual: temporal duration was perceived as shorter and the perceived line’s midpoint was shifted to the left in far than in near space. Crucially, this dissociation disappeared following a long but not short tool-use training. Finally, we observed age-related differences in spatial attention which may be crucial in building the memory temporal standard to categorize durations. (shrink)

In this paper we aim to contribute to the recent debate on non-empirical theory confirmation by analyzing why scientists accept and trust their theories in the absence of clear empirical verification in social sciences. Given that the philosophy of social sciences traditionally deals mainly with economics and sociology, organization theory promises a new area for addressing a wide range of key questions of the modern philosophy of science and, in particular, to shed a light on the puzzling question of non-empirical (...) theory assessment, acceptance, corroboration and development. Although institutional theory of organizations cannot be directly tested and evaluated via empirical data, this theory nevertheless became a dominant theory of organization-environment relations and most organizational researchers routinely use it as a standard theoretical framework for making sense of empirical findings. We analyze the trajectory of institutional theory development and proliferation and argue that it enjoys its current status of the standard theory of organizational sociology because (1) it is flexible enough to account for most organizational processes and phenomena; (2) it has suppressed existing alternative theories that are less flexible; (3) because scientists do not tend to look for alternatives for once winning theory and (4) due to the dysfunctional requirement to “develop theory” in top journals in organization and management studies. Finally, we argue that “a too-much-plasticity effect”, has a negative impact on institutional theory in the long run. It is explained why, despite the dominant position in organizational research, institutional studies cannot be regarded as a normal science while the progress of this theoretical problem is rather an illusory effect then a growth of knowledge.

The ability to learn cause–effect relations from experience is critical for humans to behave adaptively — to choose causes that bring about desired effects. However, traditional experiments on experience-based learning involve events that are artificially compressed in time so that all learning occurs over the course of minutes. These paradigms therefore exclusively rely upon working memory. In contrast, in real-world situations we need to be able to learn cause–effect relations over days and weeks, which necessitates long-term memory. 413 participants (...) completed a smartphone study, which compared learning a cause–effect relation one trial per day for 24 days versus the traditional paradigm of 24 trials back- to- back. Surprisingly, we found few differences between the short versus long timeframes. Subjects were able to accurately detect generative and preventive causal relations, and they exhibited illusory correlations in both the short and long timeframe tasks. These results provide initial evidence that experience-based learning over long timeframes exhibits similar strengths and weaknesses as in short timeframes. However, learning over long timeframes may become more impaired with more complex tasks. (shrink)

Many studies focused on the letter and sound co-occurrences to account for the well-documented syllable-based effects in French in visual (pseudo)word processing. Although these language-specific statistical properties are crucial, recent data suggest that studies which go all-in on phonological and orthographic regularities may be misguided in interpreting how – and why – readers locate syllable boundaries and segment clusters. Indeed, syllable-based effects could depend on more abstract, universal phonological constraints that rule and govern how letter and sound occur (...) and co-occur, and readers could be sensitive to sonority – a universal phonological element – for processing (pseudo)words. Here, we investigate whether French adult skilled readers rely on universal phonological sonority-related markedness continuum across the syllable boundaries for segmentation (e.g., from marked, illegal intervocalic clusters /zl/ to unmarked, legal intervocalic clusters /lz/). To address this question, we ran two tasks with 128 French adult skilled readers using two versions of the illusory conjunction paradigm (Task 1 without white noise; Task 2 with white noise). Our results show that syllable location and segmentation in reading is early and automatically modulated by phonological sonority-related markedness in the absence or quasi-absence of statistical information, and does not require acoustic-phonetic information. We discuss our results towards the overlooked role of phonological universals and the over-trusted role of statistical information during reading processes. (shrink)

This paper attempts to put some order among the different notions of pain that are to be found in the Nietzschean philosophical corpus. It tries to show that there is a mutation of the Nietzschean concept of pain, from the notion of pain as evaluation to that of pain as localization of a commotion. Therefore pain is not in itself the source of a reaction, but is actually a consequence of a commotion that a reaction has already addressed by the (...) time of the appearance of pain. A deeper notion of pain is therefore sketched here, one that depicts it as an illusory reaction, destined at separating the global commotion of the organism from its alleged localized cause, thus separating the action from the agent and postponing the facing of the global effect of the commotion. It is for this reason that pain becomes a kind of “matrix” for the understanding of our interior life for Nietzsche, as well as a philosophical indicator of his theoretical adversaries. Finally, the end of this article attempts to show that certain positive indications for a different status of pain might serve as guiding lines for the uncovering of a Nietzschean theory of action.

This is a detailed, sophisticated and comprehensive treatment of autonomy. Moreover it argues for a quite different conception of autonomy from that found in the philosophical literature. Professor Berofsky claims that the idea of autonomy originating in the self is a seductive but ultimately illusory one. The only serious way of approaching the subject is to pay due attention to psychology, and to view autonomy as the liberation from the disabling effects of physiological and psychological afflictions. A sustained (...) critique of concepts such as moral autonomy, self-realisation, ideal autonomy, and identification is offered.

On this view, not all differential treatment on the basis of racial identity is racist. (shrink)

The concept of essence is thought by many political theorists to be a residue of the patriarchal onto-theological tradition of metaphysics that needs to be (or has been) overcome by more progressive aims. The purpose of this paper is to examine the concept of essentialism in light of the treatment of the concept of essence in Hegel’s Science of Logic, and within the context of recent issues in critical race theory and feminism. I will argue that the role of an (...) essence underlying appearance is a valuable one within a Hegelian framework, and that it is politically important to reassess it. There are reasons that we should want to uphold the distinction between essence and an inessential appearance. We should want to uphold the irreducibility of essence to the Hegelian self-determining concept, and I argue in this paper that there is a basis for doing so in Hegel’s own text. Despite the well established impossibility of claiming that there is a property or set of properties that all women share, to dissolve essence as an illusory side-effect of the show of appearance is both to misunderstand essence, and to relinquish a tool needed in the struggle for justice. Essence cannot be dismissed by claiming that it is an illusory side-effect of the show of appearance because essence and the inessential do not exhibit the characteristic of reciprocity. (shrink)

In a recent paper, I argued that the mere risk of climate-related harm was itself a harm, since it undermined the security of individuals subject to that risk. In his commentary, Mintz-Woo argues that my account of the value of security is mistaken. On his view, the value of belief-relative security is already well captured by standard theories of wellbeing, and the value of fact-relative security is illusory. In the following, I attempt to respond to his concerns. First, I (...) argue contrary to Mintz-Woo that the literature on the cognitive effect on poverty is relevant to an assessment of the value of belief-relative security. Second, I introduce a distinction between ex ante and ex post perspectives on justice, and show that straightforward prioritarian commitments motivate an ex ante concern for fact-relative security.

This article deals with a phenomenological standpoint on paradoxicality of image-consciousness, i.e., an analogical representation in which an image possesses material support. Contrary to tradition, E. Husserl thought of imagination as being both an intuitive and a mediate act. Husserl’s opinion results from paradoxical nature of an image itself: an image appears but it doesn’t exist, while the exhibited thing does exist but doesn’t appear in proper sense. The paradoxicality of an image results in its double conflict — with actual (...) present and with Bildsujet. Initially, Husserl considered that the more analogous features an image possesses the less conflict exists between it and Bildsujet, but then his own experience made him change his mind. Examining a wax figure example, he came to the conclusion that this perfectly human-like object is rather a fiction than an image for it is constituted in a position-taking intention, not in a neutralized one. However, despite we’ve got knowledge of illusory nature of such an object our consciousness keeps on fluctuating between an imaging intention and a perceptual one. Unlike Husserl neither J.-P. Sartre nor M. Richir draws a distinction between an image and an illusion. Sartre considers the imaginary in its radical form to be a world of schizophrenic. As for Richir, he supposes the imaginary to be a mass-consumption product being used for ideological manipulations. He follows Plato’s intellectual strategy and characterizes an image as εἴδωλον which represents the reality instead of reaching it. Being saturated by visible an image lacks any gap that would give an impulse to a work of imagination. At the same time, Richir admits that simulacre does relate to art, whereas an artefact doesn’t. An artefact is made by technical device which imitates not reality but consciousness. Thus, an artefact in its turn is not a reality illusion but an illusion of a reality illusion. Its hallucinatory effect makes us believe that we look into a mirror of reality as if a technical agent had better access to it than a human eye does. (shrink)

ABSTRACTThe negativity bias is the tendency for individuals to give greater weight, and often exhibit more rapid and extreme responses, to negative than positive information. Using the Deese-Roediger-McDermott illusory memory paradigm, the current study sought to examine how the negativity bias might affect both correct recognition for negative and positive words and false recognition for associated critical lures, as well as how trait neuroticism might moderate these effects. In two experiments, participants studied lists of words composed of semantic (...) associates of an unpresented word. Half of the lists were comprised of positive words and half were comprised of negative words. As expected, individuals remembered negative list words better than positive list words, consistent with a negativity bias in correct recognition. When tested immediately, individuals also exhibited greater false memory for negative versus positive critical lures. When tested after a 24-hr delay... (shrink)
