Drawing from ethnographic, empirical, and historical / cultural perspectives, we examine the extent to which visual aspects of music contribute to the communication that takes place between performers and their listeners. First, we introduce a framework for understanding how media and genres shape aural and visual experiences of music. Second, we present case studies of two performances, and describe the relation between visual and aural aspects of performance. Third, we report empirical evidence that visual aspects of performance reliably (...) influence perceptions of musical structure and affective interpretations of music. Finally, we trace new and old media trajectories of aural and visual dimensions of music, and highlight how our conceptions, perceptions and appreciation of music are intertwined with technological innovation and media deployment strategies.

The ability to rapidly detect facial expressions of anger and threat over other salient expressions has adaptive value across the lifespan. Although studies have demonstrated this threat superiority effect in adults, surprisingly little research has examined the development of this process over the childhood period. In this study, we examined the efficiency of children's facial processing in visual search tasks. In Experiment 1, children (N=49) aged 8 to 11 years were faster and more accurate in detecting angry target faces embedded (...) in neutral backgrounds than vice versa, and they were slower in detecting the absence of a discrepant face among angry than among neutral faces. This search pattern was unaffected by an increase in matrix size. Faster detection of angry than neutral deviants may reflect that angry faces stand out more among neutral faces than vice versa, or that detection of neutral faces is slowed by the presence of surrounding angry distracters. When keeping the background constant in Experiment 2, children (N=35) aged 8 to 11 years were faster and more accurate in detecting angry than sad or happy target faces among neutral background faces. Moreover, children with higher levels of anxiety were quicker to find both angry and sad faces whereas low anxious children showed an advantage for angry faces only. Results suggest a threat superiority effect in processing facial expressions in young children as in adults and that increased sensitivity for negative faces may be characteristic of children with anxiety problems.

What mediates between sensory input and motor output? What makes it possible to act on what you perceive? Bence Nanay argues that pragmatic representations provide the perceptual guidance for performing actions. They play a key role in our mental lives, and help explain why the majority of our mental processes are very similar to those of animals.

Do sensory measurements deserve the label of “measurement”? We argue that they do. They fit with an epistemological view of measurement held in current philosophy of science, and they face the same kinds of epistemological challenges as physical measurements do: the problem of coordination and the problem of standardization. These problems are addressed through the process of “epistemic iteration,” for all measurements. We also argue for distinguishing the problem of standardization from the problem of coordination. To exemplify our claims, (...) we draw on olfactory performance tests, especially studies linking olfactory decline to neurodegenerative disorders. (shrink)

Our visual experience of the world is one of diverse objects and events, each with particular colors, shapes, and motions. This experience is so coherent, so immediate, and so effortless that it seems to result from a single system that lets us experience everything in our field of view. But however appealing, this belief is mistaken: there are severe limits on what can be visually experienced. -/- For example, in a display for air-traffic control it is important to track all (...) moving items. For a single item, this can be done without problem. Three or four can also be tracked, although some degree of effort may be needed. As the number is increased further, accurate tracking becomes more and more difficult—and eventually, impossible. Performance is evidently affected by a factor within the observer which enables certain kinds of perception to occur, but is limited in some way. This factor is generally referred to as attention. -/- At various times, attention has been associated with clarity of perception, intensity of perception, consciousness, selection, or the allocation of a limited “resource” enabling various operations (see Hatfield, 1998). During the past several decades, considerable progress has been achieved by focusing on the idea of selection (Broadbent, 1982). In particular, attention can be productively viewed as contingently selective processing. This can be embodied in various ways by various processes—there need not be a single quantity identified with all forms of attention, or a single site where it operates (Allport, 1993; Tsotsos, 2011). Although “paying attention” is often considered to be a unitary operation, it may simply refer to the control of one or more selective processes, ideally in a co-ordinated way. While this view has some cost in terms of conceptual simplicity, it can help make sense of a large set of phenomena. -/- This article surveys several of the major issues in our understanding of attention and how it relates to perception. It focuses on vision, since many—if not all—considerations are similar for all sensory modalities, and the level of understanding achieved in this domain is currently the most advanced. (shrink)

In a seminal 1977 article, Rumelhart argued that perception required the simultaneous use of multiple sources of information, allowing perceivers to optimally interpret sensory information at many levels of representation in real time as information arrives. Building on Rumelhart's arguments, we present the Interactive Activation hypothesis—the idea that the mechanism used in perception and comprehension to achieve these feats exploits an interactive activation process implemented through the bidirectional propagation of activation among simple processing units. We then examine (...) the interactive activation model of letter and word perception and the TRACE model of speech perception, as early attempts to explore this hypothesis, and review the experimental evidence relevant to their assumptions and predictions. We consider how well these models address the computational challenge posed by the problem of perception, and we consider how consistent they are with evidence from behavioral experiments. We examine empirical and theoretical controversies surrounding the idea of interactive processing, including a controversy that swirls around the relationship between interactive computation and optimal Bayesian inference. Some of the implementation details of early versions of interactive activation models caused deviation from optimality and from aspects of human performance data. More recent versions of these models, however, overcome these deficiencies. Among these is a model called the multinomial interactive activation model, which explicitly links interactive activation and Bayesian computations. We also review evidence from neurophysiological and neuroimaging studies supporting the view that interactive processing is a characteristic of the perceptual processing machinery in the brain. In sum, we argue that a computational analysis, as well as behavioral and neuroscience evidence, all support the Interactive Activation hypothesis. The evidence suggests that contemporary versions of models based on the idea of interactive activation continue to provide a basis for efforts to achieve a fuller understanding of the process of perception.

ABSTRACT Sensory Processing Sensitivity is an individual difference that affects people’s thinking and behavior. People who are high in SPS, Highly Sensitive People, are more sensitive to stimuli and prefer to take their time in thinking through problems. This study examined the effects of SPS and analytic mind-set on ethical decision-making. Mind-Set was manipulated by instructing participants to either think thoroughly through the ethical problem or focus on finding a concrete, practical solution when solving the problems. HSPs performed better (...) in the deliberative mind-set, allowing them to solve the problem using their natural problem-solving approach. People low in SPS performed better in the implementation mind-set. Results suggest that ethics interventions should not be “one size fits all,” and should consider a person’s natural problem-solving tendencies. (shrink)

In recent years, cognitive neuroscientists have began to explore the process of how sensory information gains access to awareness. To further probe this process, event-related functional magnetic resonance imaging was used while testing subjects with a paradigm known as the “attentional blink.” In this paradigm, visually presented information sporadically fails to reach awareness. It was found that the magnitude and time course of activation within the anterior cingulate , medial prefrontal cortex , and frontopolar cortex predicted whether or not (...) information was consciously perceived during the critical period for the attentional blink. These results are discussed in light of a neural framework for conscious processing. (shrink)

The Ouroboros Model proposes a brain inspired cognitive architecture including detailed suggestions for the main processing steps in an overall conceptualization of cognition as embodied and embedded computing. All memories are structured into schemata, which are firmly grounded in the body of an actor. A cyclic and iterative data-acquisition and -processing loop forms the backbone of all cognitive activity. Ever more sophisticated schemata are built up incrementally from the wide combination of neural activity, concurrent at the point in time when (...) the memory is established; i.e., distinct representations are accrued. Later on, an entire schema can be reinstated from diverse subsets of its constituent features. In order to decode or compile ever more elaborate constructions, extant building blocks are concatenated. They are serially linked via common or “connection-attributes” of different representations and symbols, and they are employed for serial perception, processing and action, in particular, also for language production. At various levels, commonalities between different schemata lead to a similar preferred use of their respective tokens and subsequently shared categorizations. Rules, for the concatenation of words, akin to the ones governing chemical reactions, can be abstracted. As special kinds of symbols, words and word-classes along with the whole grammar of a language can thus be seen as a direct consequence of the processes outlined in the Ouroboros Model. Strong emphasis is put on the dimension of time over short intervals during active experience and performance, and, in particular, during interactions with other agents. (shrink)

Neurophysiological studies in humans employing magneto- and electro- encephalography increasingly suggest that oscillatory rhythmic activity of the brain may be a core mechanism for binding sensory information across space, time, and object features to generate a unified perceptual representation. To distinguish whether oscillatory activity is causally related to binding processes or whether, on the contrary, it is a mere epiphenomenon, one possibility is to employ neuromodulatory techniques such as transcranial alternating current stimulation. tACS has seen a rising interest due (...) to its ability to modulate brain oscillations in a frequency-dependent manner. In the present review, we critically summarize current tACS evidence for a causal role of oscillatory activity in spatial, temporal, and feature binding in the context of visual perception. For temporal binding, the emerging picture supports a causal link with the power and the frequency of occipital alpha rhythms ; however, there is no consistent evidence on the causal role of the phase of occipital tACS. For feature binding, the only study available showed a modulation by occipital alpha tACS. The majority of studies that successfully modulated oscillatory activity and behavioral performance in spatial binding targeted parietal areas, with the main rhythms causally linked being the theta and beta frequency bands. On the other hand, spatio-temporal binding has been directly modulated by parieto-occipital gamma and alpha tACS, suggesting a potential role of cross-frequency coupling when binding across space and time. Nonetheless, negative or partial results have also been observed, suggesting methodological limitations that should be addressed in future research. Overall, the emerging picture seems to support a causal role of brain oscillations in binding processes and, consequently, a certain degree of plasticity for shaping binding mechanisms in visual perception, which, if proved to have long lasting effects, can find applications in different clinical populations.

The existence of sensory convergence does not establish that the senses function as a single unified perceptual system. Reality is fully specified only by a one:many mapping onto the totality of energy arrays, and these provide alternative frames of reference for movement. It is therefore possible that higher order crossmodal relationships are detected by skilled perceivers, but this has not been confirmed empirically.

Bringing about desirable collisions (making interceptions) and avoiding unwanted collisions are critically important sensorimotor skills, which appear to require us to estimate the time remaining before collision occurs (time-to-collision). Until recently the theoretical approach to understanding time-to-collision estimation has been dominated by the tau-hypothesis, which has its origins in J.J. Gibson’s ecological approach to perception. The hypothesis proposes that a quantity (tau), present in the visual stimulus, provides the necessary time-to-collision information. Empirical results and formal analyses have now accumulated (...) to demonstrate conclusively that the tau-hypothesis is false. This article describes an alternative approach that is based on recent data showing that the information used in judging time-to-collision is task- and situation-dependent, is of many different origins (of which tau is just one) and is influenced by the information-processing constraints of the nervous system.

The entrepreneurial firms may be more vulnerable to the COVID-19 pandemic, and the entrepreneurs of entrepreneurial firms are also threatened by the revenues decline and business failure, which vehemently affect their well-being. The mental health of the entrepreneur decides whether the entrepreneurial firms can make the right decision, which is related to the healthy development of the entrepreneurial firms. Based on the event system theory and the cognitive appraisal theory, this paper aims to explore the effect of COVID-19 pandemic on (...) the entrepreneur anxiety, and the threat perception and performance pressure are introduced to investigate the mediating mechanism and boundary of this effect. Using the simple random sampling to obtain questionnaire survey data, 168 entrepreneurs of entrepreneurial firms have participated in the empirical study, and the research results are as follows. First, the COVID-19 pandemic significantly positively affects entrepreneur anxiety. Second, the entrepreneur threat perception plays a mediating role between the COVID-19 pandemic and the entrepreneur anxiety, which means the COVID-19 pandemic can enhance the external threat perception of entrepreneurs, and then affect the entrepreneur anxiety. Third, the positive effect of the COVID-19 pandemic on the entrepreneur anxiety is strengthened by the entrepreneur performance pressure, while the positive effect of entrepreneur threat perception on entrepreneur anxiety is weakened by the entrepreneur performance pressure. The above findings are helpful to explore the mechanism of the COVID-19 pandemic and other critical crisis events on entrepreneurs’ mental health from the new perspective of cognitive appraisal theory and event system theory, filling the research gaps between the COVID-19 pandemic and entrepreneur anxiety. Besides, this study broadens the applied range of the cognitive appraisal theory and the event system theory in the fields of crisis situations and entrepreneur research, and enriches the research outputs. Furthermore, this study will help provide a new theoretical analysis insight for the related research on how the COVID-19 pandemic affects entrepreneurs’ psychology, and further deepen researchers to understand the mechanism of entrepreneur anxiety under the COVID-19 pandemic, providing theoretical inspirations for reducing entrepreneur anxiety. What’s more, this study finds that individual pressure can affect their cognitive appraisal, which means that future research should take the pressure influential mechanism into consideration in the process of exploring “external stimulus--cognitive appraisal--emotional response,” further expanding the theoretical model of cognitive appraisal proposed from the perspective of pressure.

Female competition generally takes nonviolent form, but includes intense verbal and nonverbal harassment that has profound social and physiological consequences.

Evidence from neurophysiological and psychological studies is coming together to shed light on how we represent and recognize objects. This review describes evidence supporting two major hypotheses: the first is that objects are represented in a mosaic-like form in which objects are encoded by combinations of complex, reusable features, rather than two-dimensional templates, or three-dimensional models. The second hypothesis is that transform-invariant representations of objects are learnt through experience, and that this learning is affected by the temporal sequence in which (...) different views of the objects are seen, as well as by their physical appearance.

Sensory Individuals: Unimodal and Multimodal Perspectives provides an interdisciplinary, well-balanced, and comprehensive look at different aspects of unisensory and multisensory objects, using both nuanced philosophical analysis and informed empirical work. The research presented in this book represents the field's progression from treating neural sensory processes as primarily modality-specific towards its current state of the art, according to which perception, and its supporting neural processes, are multi-modal, modality-independent, meta-modal, and task-dependent. Even within such approaches sensory stimuli, properties, (...) brain activations, and corresponding perceptual phenomenology can still be characterized in a modality-specific way. The book examines the basic building blocks of human perception, and whether they are best understood as sense modality dependent units of different forms or multimodal perceptual objects. The book combines a variety of innovative and integrative angles to explore the topic and acts as a catalyst for an increasingly diverse field of research, which is in an exciting phase of growth and advancement. New questions are arising as quickly as they are being answered, and the collection Sensory Individuals provides an original and up-to-date addition to the field. (shrink)

There is currently no consensus regarding what measures are most valid to demonstrate perceptual processing without awareness. Likewise, whether conscious perception and unconscious processing rely on independent mechanisms or lie on a continuum remains a matter of debate. Here, we addressed these issues by comparing the time courses of subjective reports, objective discrimination performance and response priming during meta-contrast masking, under similar attentional demands. We found these to be strikingly similar, suggesting that conscious perception and unconscious processing (...) cannot be dissociated by their time course. Our results also demonstrate that unconscious processing, indexed by response priming, occurs, and that objective discrimination performance indexes the same conscious processes as subjective visibility reports. Finally, our results underscore the role of attention by showing that how much attention the stimulus receives relative to the mask, rather than whether processing is measured by conscious discrimination or by priming, determines the time course of meta-contrast masking.

We investigate the dynamics of sensory integration for perceiving musical performance, a complex natural behavior. Thirty musically trained participants saw, heard, or both saw and heard, performances by two clarinetists. All participants used a sliding potentiometer to make continuous judgments of tension (a measure correlated with emotional response) and continuous judgments of phrasing (a measure correlated with perceived musical structure) as performances were presented. The data analysis sought to reveal relations between the sensory modalities (vision and audition) (...) and to quantify the effect of seeing the performances on participants' overall subjective experience of the music. In addition to traditional statistics, functional data analysis techniques were employed to analyze time-varying aspects of the data. The auditory and visual channels were found to convey similar experiences of phrasing but different experiences of tension through much of the performances. We found that visual information served both to augment and to reduce the experience of tension at different points in the musical piece (as revealed by functional linear modeling and functional significance testing). In addition, the musicians' movements served to extend the sense of phrasing, to cue the beginning of new phrases, to indicate musical interpretation, and to anticipate changes in emotional content. Evidence for an interaction effect suggests that there may exist an emergent quality when musical performances are both seen and heard. The investigation augments knowledge of human communicative processes spanning language and music, and involving multiple modalities of emotion and information transfer. (shrink)

Ever since I first saw a dance performance I have wondered why it is that I am sometimes fascinated and touched by some people moving about on a stage, while at other times it leaves me completely indifferent. I will argue that an answer to this question has to be searched for in the way sensory stimuli are processed in the brain. After all, all our actions, perceptions and feelings are mediated and controlled by the brain. The thoughts (...) and feelings evoked by a dance performance are no exception and thus they too have a neural substrate in the brain. (shrink)

The sounds that result from our movement and that mark the outcome of our actions typically convey useful information concerning the state of our body and its movement, as well as providing pertinent information about the stimuli with which we are interacting. Here we review the rapidly growing literature investigating the influence of non-veridical auditory cues (i.e., inaccurate in terms of their context, timing, and/or spectral distribution) on multisensory body and action perception, and on motor behavior. Inaccurate auditory cues (...) provide a unique opportunity to study cross-modal processes: the ability to detect the impact of each sense when they provide a slightly different message is greater. Additionally, given that similar cross-modal processes likely occur regardless of the accuracy or inaccuracy of sensory input, studying incongruent interactions are likely to also help us predict interactions between congruent inputs. The available research convincingly demonstrates that perceptions of the body, of movement, and of surface contact features (e.g., roughness) are influenced by the addition of non-veridical auditory cues. Moreover, auditory cues impact both motor behavior and emotional valence, the latter showing that sounds that are highly incongruent with the performed movement induce feelings of unpleasantness (perhaps associated with lower processing fluency). Such findings are relevant to the design of auditory cues associated with product interaction, and the use of auditory cues in sport performance and therapeutic situations given the impact on motor behavior.

Discussions of the relationship between perception and cognition often proceed without a definition of these terms. The sensory-modality specific nature of low-level perceptual processes provides a means of distinguishing them from cognitive processes. A more explicit definition of terms provides insight into the nature of the evidence that can resolve questions about the relationship between perception and cognition.

Guilt and shame are self-conscious emotions with implications for mental health, social and occupational functioning, and the effectiveness of sports practice. To date, the assessment and role of athlete-specific guilt and shame has been under-researched. Reporting data from 174 junior elite cricketers, the present study utilized exploratory factor analysis in validating the Athletic Perceptions of Performance Scale, assessing three distinct and statistically reliable factors: athletic shame-proneness, guilt-proneness, and no-concern. Conditional process analysis indicated that APPS shame-proneness mediated the relationship between (...) general and athlete-specific distress. While APPS domains of guilt-proneness and no-concern were not significant mediators, they exhibited correlations in the expected direction with indices of psychological distress and well-being. The APPS may assist coaches and support staff identify players who may benefit from targeted interventions to reduce the likelihood of experiencing shame-prone states. (shrink)

Using fMRI, we investigated how right temporal lobe gliomas affecting the posterior superior temporal sulcus alter neural processing observed during speech perception and production tasks. Behavioural language testing showed that three pre-operative neurosurgical patients with grade 2, grade 3 or grade 4 tumours had the same pattern of mild language impairment in the domains of object naming and written word comprehension. When matching heard words for semantic relatedness (a speech perception task), these patients showed under-activation in the tumour (...) infiltrated right superior temporal lobe compared to 61 neurotypical participants and 16 patients with tumours that preserved the right postero-superior temporal lobe, with enhanced activation within the (tumour-free) contralateral left superior temporal lobe. In contrast, when correctly naming objects (a speech production task), the patients with right postero-superior temporal lobe tumours showed higher activation than both control groups in the same right postero-superior temporal lobe region that was under-activated during auditory semantic matching. The task dependent pattern of under-activation during the auditory speech task and over-activation during object naming was also observed in eight stroke patients with right hemisphere infarcts that affected the right postero-superior temporal lobe compared to eight stroke patients with right hemisphere infarcts that spared it. These task-specific and site-specific cross-pathology effects highlight the importance of the right temporal lobe for language processing and motivate further study of how right temporal lobe tumours affect language performance and neural reorganisation. These findings may have important implications for surgical management of these patients, as knowledge of the regions showing functional reorganisation may help to avoid their inadvertent damage during neurosurgery.

Is perceptual processing in dedicated sensory areas sufficient for conscious perception? Localists say ‘Yes—given some background conditions.’ Prefrontalists say ‘No: conscious perceptual experience requires the involvement of prefrontal structures.’ I review the evidence for prefrontalism. I start by presenting correlational evidence. In doing so, I answer the ‘report argument’, according to which the apparent involvement of the prefrontal cortex in consciousness stems from the requirement for reports. I then review causal evidence for prefrontalism and answer the ‘lesion argument’, (...) which purports to show that prefrontalism is wrong because lesions to the prefrontal cortex do not abolish consciousness. I conclude that multiple sources of evidence converge toward the view that the prefrontal cortex plays a significant role in consciousness. (shrink)

Spirit possessions, trance, and other forms of altered states of consciousness are fascinating manifestations of brain states that are often seen as alien or exotic in Western media and discourse. Yet, these experiences are very common for a large number of humans around the world. In this paper we use a predictive processing perspective to examine spirit possession in Taoist rituals in Southern Thailand. These rituals involve tens of thousands of spirit mediums that enter into trance and perform various acts (...) of selfmutilation. These activities can shed new light on how sensory input is modulated and reinterpreted through top-down expectations driven by cultural narratives and frameworks. Our key argument is that, instead of being exotic and different, these states of altered consciousness provide us with powerful insights into how the mind and perception work in a culturally constructed world. Considering the role of culture as providing input into a common human cognitive architecture allows for a deeper understanding of the various facets and expressions of communalities in altered states of consciousness across human populations.

From the outside, our senses are spatially integrated in our body in manifestly different ways. This paper starts from the suggestion that the philosophical formulation of the problem of spatial perception, as it flows from the modern opposition of mind and world, is partly responsible for the fact that philosophers have often explicitly disregarded the spatial nature of the senses themselves. An indirect consequence is that much philosophical work focuses on how the senses can – or cannot – perceive (...) the same spatial features of objects in the same way, while disregarding the massive differences in performance among the senses. This paper explores the ways in which the spatial integration of our senses determines what each of our senses excels in, and hence what they contribute to our spatial relation to a physical environment. By juxtaposing descriptive analyses of a variety of selected cases, the paper gives priority to how various aspects of the world appear to us in order to obtain insight into the meaning of spatiality for different senses.

Atypical sensorimotor developmental trajectories greatly contribute to the profound heterogeneity that characterizes Autism Spectrum Disorders. Individuals with ASD manifest deviations in sensorimotor processing with early markers in the use of sensory information coming from both the external world and the body, as well as motor difficulties. The cascading effect of these impairments on the later development of higher-order abilities underlines the need for interventions that focus on the remediation of sensorimotor integration skills. One of the promising technologies for such (...) stimulation is Immersive Virtual Reality. In particular, head-mounted displays have unique features that fully immerse the user in virtual realities which disintegrate and otherwise manipulate multimodal information. The contribution of each individual sensory input and of multisensory integration to perception and motion can be evaluated and addressed according to a user’s clinical needs. HMDs can therefore be used to create virtual environments aimed at improving people’s sensorimotor functioning, with strong potential for individualization for users. Here we provide a narrative review of the sensorimotor atypicalities evidenced by children and adults with ASD, alongside some specific relevant features of IVR technology. We discuss how individuals with ASD may interact differently with IVR versus real environments on the basis of their specific atypical sensorimotor profiles and describe the unique potential of HMD-delivered immersive virtual environments to this end.

The mechanics of this process is explored in detail to show how Malebranche was challenging honnête thinking. The article suggests that (...) Malebranche’s demystifying approach was at once a hallmark of the Enlightenment, and that his views would ironically come to inform much Enlightenment thought about taste in ways he would have despised.

Cells live in dynamic environments that necessitate perpetual adaptation. Since cells have limited resources to monitor external inputs, they are required to maximize the information content of perceived signals. This challenge is not unique to microscopic life: Animals use senses to perceive inputs and adequately respond. Research showed that sensory‐perception is actively shaped by learning and expectation allowing internal cognitive models to “fill in the blanks” in face of limited information. We propose that cells employ analogous strategies and (...) use internal models shaped through the long process of evolutionary adaptation. Given this perspective, we postulate that cells are prone to “misperceptions,” analogous to visual illusions, leading them to incorrectly decode patterns of inputs that lie outside of their evolutionary experience. Mapping cellular misperception can serve as a fundamental approach for dissecting regulatory networks and could be harnessed to modulate cell behavior, a potentially new avenue for therapy. (shrink)

In visual information processing, two kinds of vision are distinguished: vision-for-perception related to the conscious identifi cation of objects, and vision-for-action that deals with visual control of movements. Neuroscience suggests that these two functions are performed by two separate brain neural systems - the ventral and dorsal pathways. Two experiments using behavioural measures were conducted with the objective of exploring any potential interaction between these two functions of vision. The aim was to combine in one task methods allowing for (...) the simultaneous capture of both perceptual global processing and affordance extraction and to check whether they infi uence each other. This aim was achieved by employing the paradigms of Navon and Tucker and Ellis. A compound fi gure was created made up of objects with handles that might or might not have orientation congruent between levels. The results revealed that while the affordance effect occurred every time, the Navon effect appeared only when subjects focused their attention on object elements responsible for inconsistence within compound fi gure. Most importantly, even when these two effects occurred at once, they had no effect on each other. Results from the study failed to confi rm the hypothesis about interaction and gives support to the view that vision-for-perception and vision-for-action tend to act as separate systems. (shrink)

Politics has become a common element in the performance appraisal process, and as decision recipients in this process, those appraised tend to be more sensitive to performance appraisal politics. This paper examines the mechanisms by which performance appraisal politics perception affects counterproductive work behavior from the perspective of those appraised. The mediating effect of perceived organizational justice and the moderating effect of political skill are incorporated into a parsimonious moderated-mediation model. A quantitative research approach is employed (...) with survey data from 460 employees of large and medium-sized enterprises in Hubei Province, and structural equation modeling and bootstrap analysis are used to test the proposed hypothesized relationships. The findings demonstrate that PAPP has a positive impact on CWB, and POJ partly mediates the relationship between PAPP and CWB. The results also reveal that individual PS moderates the positive correlation between PAPP and CWB. The academic and practical implications of these findings, as well as limitations and suggestions for future research, are also discussed. (shrink)

This paper offers a conceptual clarification of the phenomenon commonly referred to as categorical perception of color, both in adults and in infants. First, I argue against the common notion of categorical perception as involving a distortion of the perceptual color space. The effects observed in the categorical perception research concern categorical discrimination performance and the underlying processing; they need not directly reflect the relations of color similarity and difference. Moreover, the methodology of the research actually (...) presupposes that the relations of similarity and difference do not vary with languages. The observed categorical perception effects should be conceived independently of the perceptual color space. Second, I challenge the usual opinion that the existing evidence on infant “categorical perception” allows us to conclude that infants perceptually categorize color, and in particular, that they have perceptual categories that resemble the basic color categories of English. Such conclusions rest on an unjustified interpretation of the infant “categorical perception” findings in terms of adult linguistic categorical boundaries. Based on the suggested new understanding, I propose that the phenomenon, as present in infants, should be conceived and examined as a possible explanatory factor with respect to the existing patterns of color naming in languages of the world.

In lieu of an abstract, here is a brief excerpt of the content:The Image of the Performing BodyEric C. Mullis (bio)Elsewhere I have discussed the principles of embodied expression that are developed in the practice of the performance arts—dance and theatre.1 These principles, it was argued, disclose the work that must be done in order to transform the human body into an aesthetically expressive medium. That is, precarious balance, the interplay of oppositional energies, and the compression of energy must (...) be mastered if a performance artist is to overcome the artifice of the stage and develop scenic presence. However, in that essay I said little regarding the manner in which the body acquires these skills and little about the effects that the transformation has on the artist's experience of embodiment. I would like to continue here by discussing how the body is modified in the process of developing the skill sets necessary for performance as well as how this developmental process affects the performer's corporeal experience. More specifically, I will draw on the notions of the body schema and the body image in order to clarify how the body can be transformed into an aesthetically expressive medium. In the first section I discuss the functions of the body image and body schema as well as the nature of their interaction. In the second section I discuss what relevance these concepts have for our understanding of the skill acquisition process. Finally, since the points made in the first two sections can be applied to non-peformative practices (such as sport, yoga, and martial arts) the last section focuses on the performance arts by discussing how the body schema and body image are developed in order to create a space of effective gesture.Body Image and Body SchemaShaun Gallagher argues that "The body image consists of a complex set of intentional states and dispositions—perceptions, beliefs, and attitudes—in [End Page 62] which the intentional object is one's own body."2 That is, there are three kinds of intentional content that constitute the body image—the body percept, the body concept, and the body affect. The image of my body is rooted in sensorimotor and kinesthetic perceptions, specific beliefs about my body, as well as emotions that often arise in response to such beliefs. Perception gives me a sense of the condition of my body at any point in time, while conceptions build upon perceptual content and allow one to understand the nature of one's embodiment. For example, the belief that the body is akin to a machine that can run well, break down, be diagnosed, and repaired is widespread since it is based in a widely accepted philosophy of medicine. That is, the body is often conceived as a thing that must be fixed by those who have the expertise that allows them to understand its intricate systems and processes. This example not only gives us insight into the perceptual and conceptual content of the body image but also demonstrates that beliefs about the body are conditioned by culture. This latter point is also supported by observations regarding the manner in which the body is invested with emotion. For example, some may feel frustrated with their bodies since they do not meet social standards of beauty, while others experience the joys of physical competition and accomplishment that are brought about by participating in widely practiced games. This brief discussion illustrates that the image that one has of one's body is a synthesis of perceptual experience, beliefs about the nature of one's body, and emotional responses.In 1911 Head and Holmes defined the body schema as the postural model of the body.3 In this account, the body schema functions by continually comparing the body's present posture to those held in the immediate past. That is, at the preconscious level, the schema provides a standard against which changes in posture can be judged. It must be stressed that the body schema functions below the surface of consciousness and, unlike the body image, does not include perceptions, attitudes, or beliefs about the body and is consequently not subject to cultural influence. Gallagher notes that the body schema "is a system of sensory-motor... (shrink)

Numerous studies have examined the acoustic correlates of sentential stress and its underlying linguistic functionality. However, the mechanism that connects stress cues to the listener's attentional processing has remained unclear. Also, the learnability versus innateness of stress perception has not been widely discussed. In this work, we introduce a novel perspective to the study of sentential stress and put forward the hypothesis that perceived sentence stress in speech is related to the unpredictability of prosodic features, thereby capturing the attention (...) of the listener. As predictability is based on the statistical structure of the speech input, the hypothesis also suggests that stress perception is a result of general statistical learning mechanisms. To study this idea, computational simulations are performed where temporal prosodic trajectories are modeled with an n-gram model. Probabilities of the feature trajectories are subsequently evaluated on a set of novel utterances and compared to human perception of stress. The results show that the low-probability regions of F0 and energy trajectories are strongly correlated with stress perception, giving support to the idea that attention and unpredictability of sensory stimulus are mutually connected.

Experimental investigations of cross-cultural music perception and cognition reported during the past decade are described. As globalization and Western music homogenize the world musical environment, it is imperative that diverse music and musical contexts are documented. Processes of music perception include grouping and segmentation, statistical learning and sensitivity to tonal and temporal hierarchies, and the development of tonal and temporal expectations. The interplay of auditory, visual, and motor modalities is discussed in light of synchronization and the way music (...) moves via emotional response. Further research is needed to test deep-rooted psychological assumptions about music cognition with diverse materials and groups in dynamic contexts. Although empirical musicology provides keystones to unlock musical structures and organization, the psychological reality of those theorized structures for listeners and performers, and the broader implications for theories of music perception and cognition, awaits investigation.

Dancers and musicians are experts in spatial and temporal processing which allows them to coordinate movement with music. This high-level processing has been associated with structural and functional adaptation of the brain for high performance sensorimotor integration. For these integration processes, adaptation does not only take place in primary and secondary sensory and motor areas but tertiary brain areas, such as the lateral prefrontal cortex (lPFC) and the intraparietal sulcus (IPS), also provide vital resources for highly specialized (...) class='Hi'>performance. Here, we review evidence for the role of these brain areas in multimodal training protocols and integrate these findings into a new model of sensorimotor processing in complex motor learning.

Philosophical discussion about the reality of sensory perceptions has been hijacked by two tendencies. First, talk about perception has been largely centered on vision. Second, the realism question is traditionally approached by attaching objects or material structures to matching contents of sensory perceptions. These tendencies have resulted in an argumentative impasse between realists and anti-realists, discussing the reliability of means by which the supposed causal information transfer from object to perceiver takes place. Concerning the nature of (...) class='Hi'>sensory experiences and their capacity to provide access to reality, this article challenges the standard categories through which most arguments in this debate have been framed to date. Drawing on the underexplored case of olfaction, I first show how the details of the perception process determine the modalities of sensory experiences. I specifically examine the role of measurement and analyze its influence on the characterization of perceptions in olfaction. My aim is to argue for an understanding of perception through a process view, rather than one pertaining to objects and properties of objects. (shrink)

Although there has been steady progress elucidating the influence of emotion on cognition, it remains unclear precisely when and why emotion impairs or facilitates cognition. The present study investigated the mechanisms involved in the influence of emotion on perception and working memory, using modified 0-back and 2-back tasks, respectively. First, results showed that attentional focus modulated the impact of emotion on perception. Specifically, emotion facilitated perceptual task performance when it was relevant to the task, but it impaired (...) performance when it was irrelevant to the task. The differential behavioural effect of emotion on perception as a function of attentional focus diminished under high WM load. Second, attentional focus did not directly modulate the impact of emotion on WM, but rather its influence depended on the dynamic relationship between internal representations. Specifically, WM performance was worse when the material already being held online and the new input were of matching emotions, compared to when they were not. We propose that the competition between “bottom-up” and “top-down” processing for limited cognitive resources explains the nature of the influence of emotion on both perception and WM. (shrink)

This volume is dedicated to the topic of the human evaluation and interpretation of animals in ancient and medieval cultures. From a transcultural perspective contributions from Assyriology, Byzantine Studies, Classical Archaeology, Egyptology, German Medieval Studies and Jewish History look into the processes and mechanisms behind the transfer by people of certain values to animals, and the functions these animal-signs have within written, pictorial and performative forms of expression.

This study was directed towards personality-related, value system and sociodemographic variables of nursing students in a situation of change, using a longitudinal perspective to measure their improvement in principle-based moral judgement (Kohlberg; Rest) as possible predictors of stress. Three subgroups of students were included from the commencement of the first three-year academic nursing programme in 1993. The students came from the colleges of health at Jönköping, Växjö and Kristianstad in the south of Sweden. A principal component factor analysis (varimax) was (...) performed using data obtained from the students in the spring of 1994 (n = 122) and in the spring of 1996 (n = 112). There were 23 variables, of which two were sociodemographic, eight represented self-image, six were self-values, six were interpersonal values, and one was principle-based moral judgement. The analysis of data from students in the first year of a three-year programme demonstrated eight factors that explained 68.8% of the variance. The most important factors were: (1) ascendant decisive disorderly sociability and nonpractical mindedness (18.1% of the variance); (2) original vigour person-related trust (13.3% of the variance); (3) orderly nonvigour achievement (8.9% of the variance) and (4) independent leadership (7.9% of the variance). (The term ‘ascendancy’ refers to self-confidence, and ‘vigour’ denotes responding well to challenges and coping with stress.) The analysis in 1996 demonstrated nine factors, of which the most important were: (1) ascendant original sociability with decisive nonconformist leadership (18.2% of the variance); (2) cautious person-related responsibility (12.6% of the variance); (3) orderly nonvariety achievement (8.4% of the variance); and (4) nonsupportive benevolent conformity (7.2% of the variance). A comparison of the two most prominent factors in 1994 and 1996 showed the process of change to be stronger for 18.2% and weaker for 30% of the variance. Principle-based moral judgement was measured in March 1994 and in May 1996, using the Swedish version of the Defining Issues Test and Index P. The result was that Index P for the students at Jönköping changed significantly (paired samples t-test) between 1994 and 1996 (p = 0.028), but that for the Växjö and Kristianstad students did not. The mean of Index P was 44.3% at Växjö, which was greater than the international average for college students (42.3%); it differed significantly in the spring of 1996 (independent samples t-test), but not in 1994, from the students at Jönköping (p = 0.032) and Kristianstad (p = 0.025). Index P was very heterogeneous for the group of students at Växjö, with the result that the paired samples t-test reached a value close to significance only. (shrink)

The use of artificial intelligence (AI) in hiring entails vast ethical challenges. As such, using an ethical lens to study this phenomenon is to better understand whether and how AI matters in hiring. In this paper, we examine whether ethical perceptions of using AI in the hiring process influence individuals’ trust in the organizations that use it. Building on the organizational trust model and the unified theory of acceptance and use of technology, we explore whether ethical perceptions are shaped by (...) individual differences in performance expectancy and social influence and how they, in turn, impact organizational trust. We collected primary data from over 300 individuals who were either active job seekers or who had recent hiring experience to capture perceptions across the full range of hiring methods. Our findings indicate that performance expectancy, but not social influence, impacts the ethical perceptions of AI in hiring, which in turn influence organizational trust. Additional analyses indicate that these findings vary depending on the type of hiring methods AI is used for, as well as on whether participants are job seekers or individuals with hiring experience. Our study offers theoretical and practical implications for ethics in HRM and informs policy implementation about when and how to use AI in hiring methods, especially as it pertains to acting ethically and trustworthily.

The original extended mind theory propagated by Clark and Chalmers (Analysis 58:7–19, 1998) refers to the idea that our minds do not simply live within our brains or bodies but extend into the material world. In other words, the extended mind refers to the externalization of cognitive processes into technology. Through the case study of the artistic performance of the android Alter inspired by the Japanese Shintoist ritual of Kagura this paper reconceptualizes the extended mind from a technological act (...) of transfer towards the relational, spatial, and performative ontologies of the intersubjective encounters between humans and non-humans. In an effort to decolonize performance and curatorial practice the paper draws upon indigenous scholarship, feminist STS, and performance studies to overcome preconceived conceptualizations of affect, perception, and relationality. The fundamental question the paper explores is how does intersubjective relationality unfold through performance in space? Based upon a critique of the android Alter’s past performance the paper concludes with a re-envisioned event score that employs a reconceptualized theory of the extended mind and aimed at a different kind of intersubjective relationality to emerge.

It is increasingly common in cognitive science and philosophy of perception to regard perceptual processing as a probabilistic engine, taking into account uncertainty in computing representations of the distal environment. Models of this kind often postulate probabilistic representations, or what we will call probabilistic states,. These are states that in some sense mark or represent information about the probabilities of distal conditions. It has also been argued that perceptual experience itself in some sense represents uncertainty (Morrison _Analytic Philosophy_ 57 (...) (1): 15 48, 2016 ). In this article, we will first consider three models of sensory activity from perceptual neuroscience, namely signal detection theory (SDT), probabilistic population codes (PPC), and sampling. We will then reflect on the sense in which the probabilistic states introduced in these models are probabilistic representations. To sharpen this discussion, we will compare and contrast these probabilistic states to credences as they are understood in epistemology. We will suggest that probabilistic representation, in an appropriately robust sense, can be understood as a form of analog representation. In the last part of the paper, we apply this to the issue of whether conscious experience represents uncertainty—we will interpret this as the claim that there are phenomenal features of experience that serve as analog probabilistic representations.
