Abstract Action and vision are known to be tightly coupled with each other. In a previous study, we found that repeatedly grasping an object without any visual feedback might result in a perceptual aftereffect when the object was visually presented in the context of a perceptual judgement task. In this study, we explored whether and how such an effect could be modulated by presenting the object behind a transparent barrier. Our conjecture was that if perceptual judgment relies, in part at least, on the same processes and representations as those involved in action, then one should expect to find a slowdown in judgment performance when the target object looks to be out of reach. And this was what we actually found. This indicates that not only acting upon an object but also being prevented from acting upon it can affect how the object is perceptually judged.

Cognition constantly involves retrieving and maintaining information that is not perceptually available in the current environment. Studies on visual imagery and working memory suggest that such high-level cognition might, in part, be mediated by the revival of perceptual representations in the inferior temporal cortex. Here, we provide new support for this hypothesis, showing that reflectively accessed information can have similar consequences for subsequent perception as actual perceptual input. Participants were presented with pairs of frames in which a scene could appear, and were required to make a category judgment on the second frame. In the critical condition, a scene was presented in the first frame, but the second frame was blank. Thus, it was necessary to refresh the scene from the first frame in order to make the category judgment. Scenes were then repeated in subsequent trials to measure the effect of refreshing on functional magnetic resonance imaging repetition attenuation—a neural index of memory—in a scene-selective region of the visual cortex. Surprisingly, the refreshed scenes produced equal attenuation as scenes that had been presented twice during encoding, and more attenuation than scenes that had been presented once during encoding, but that were not refreshed. Thus, the top-down revival of a percept had a similar effect on memory as actually seeing the stimulus again. These findings indicate that high-level cognition can activate stimulus-specific representations in the ventral visual cortex, and that such top-down activation, like that from sensory stimulation, produces memorial changes that affect perceptual processing during a later encounter with the stimulus.

Charles Travis influentially argued in “The Silence of the Senses” that the representational theory of perceptual experience is false. According to Travis, the way that things look cannot index the content of experience as the subject of the experience cannot read the content off from the way things look. This looks indexing is a central commitment of representationalism. The main thrust of Travis’ argument is that the way things look is fundamentally comparative, and this prevents the subject from reading a single content off from the way things look. If content were looks indexed, the subject would be able to do this. I argue that Travis’ argument rests on an illicit transition from an argument about the way objects look in themselves—i.e. an argument about the visible properties that they have—to a conclusion about the way that objects look to subjects in experience.

The working hypothesis in this project is that gaze interactions play a central role in structuring the joint control and guidance strategy of the human operator performing spatial tasks. Perceptual guidance and control is the idea that the visual and motor systems form a unified perceptuo-motor system where necessary information is naturally extracted by the visual system. As a consequence, the response of this system is constrained by the visual and motor mechanisms and these effects should manifest in the behavioral data. Modeling the perceptual processes of the human operator provides the foundation necessary for a systems-based approach to the design of control and display systems used by remotely operated vehicles. This paper investigates this hypothesis using flight tasks conducted with remotely controlled miniature rotorcraft, taking place in indoor settings that provide rich environments to investigate the key processes supporting spatial interactions. This work also applies to spatial control tasks in a range of application domains that include tele-operation, gaming, and virtual reality. The human-in-the-loop system combines the dynamics of the vehicle, environment, and human perception–action with the response of the overall system emerging from the interplay of perception and action. The main questions to be answered in this work are as follows: (i) what is the general control and guidance strategy of the human operator, and (ii) how is information about the vehicle and environment extracted visually by the operator. The general approach uses gaze as the primary sensory mechanism by decoding the gaze patterns of the pilot to provide information for estimation, control, and guidance. This work differs from existing research by taking what have largely been conceptual ideas on action–perception and structuring them to be implemented for a real-world problem. The paper proposes a system model that captures the human pilot’s perception–action loop; the loop that delineates the main components of the pilot’s perceptuo-motor system, including estimation of the vehicle state and task elements based on operator gaze patterns, trajectory planning, and tracking control. The identified human visuo-motor model is then exploited to demonstrate how the perceptual and control functions system can be augmented to reduce the operator workload.

In 1968, Nelson Goodman made an observation about artistic forgery that has never been fully appreciated, though his discussion of forgery has received plenty of philosophical attention. Goodman describes the case in which you, the viewer, are confronted with an original work and a forgery that is, for you, perceptually indistinguishable from it. On the basis of lab tests, you know which of the works is forged, but you can see no difference between them. Nonetheless, Goodman says, the knowledge that one of them is forged makes for an aesthetic difference between the works, for you, now. One reason is that this knowledge changes the way you look at the works, and the way you should look at them; it alters the sorts of scrutiny it is appropriate to apply. In fact, knowledge that one of the works is forged ‘assigns the present looking a role as training toward … perceptual discrimination’ (Goodman, 1976,105).

PurposeDigital repositories offer a great benefit to people in a variety of settings, especially since an ever‐increasing amount of information is being gathered, transmitted, and preserved through various technologies. The purpose of this paper is to underscore trust as a critical element in the infrastructure of digital repositories and to look more closely at trusted digital repositories from the perspective of the user communities for which they are designed.Design/methodology/approachThe paper looks to the literature in reviewing the concept of trust and its role in an online environment. Attention is then paid to trusted digital repositories, with close examination of the user communities’ perceptions of trust and the impact of these perceptions. Special attention is given to users within the academic community.FindingsWhile digital repositories may be trustworthy because of adherence to technological standards, accepted practices, and mechanisms for authenticating the authorship and accuracy of their content, it is ultimately their respective stakeholders – both those who deposit and use content – whose perceptions play a central role in ensuring a digital repository's trustworthiness.Research limitations/implicationsA future empirical study would be beneficial in order to measure perceptions of trust as contributing factors to the trustworthiness of digital repositories.Practical implicationsThis paper provides a useful resource for persons wishing to review the topic of trusted digital repositories or increase their awareness in this area.Originality/valueThis paper offers a focused look at various levels of trust as they relate to the dissemination of scholarly communication in the academic world, particularly through institutional repositories.

Image-to-semantic labels classification is a very challenging task in image processing. Convolutional neural networks (CNN) have managed to achieve the state-of-the-art quality of the segmented image in semantic segmentation tasks. Still, the classification capability of such algorithms is not satisfactory to segment images that contain complex object boundaries and minimal regions. Recently, the Generative Adversarial Networks (GAN) were introduced, which can solve the overfitting of the generator network using the adversarial loss. In this paper, a GAN-based segmentation model is proposed, in which the Conditional Generative Adversarial Networks (CGAN) model is used as base architecture. Perceptual loss is introduced in this composite model to solve the identification and classification of visually small elements in images. A pre-trained deep convolution neural network is adopted to generate improved segmentation masks to calculate Perceptual loss. The usage of Perceptual loss has demonstrated the high quality of the output labels. The evaluation of the proposed model on the cityscapes dataset has shown the effectiveness of GAN-based architecture in semantic segmentation of multiclass images. The proposed model achieved 83.3% accuracy on the test dataset, which is superior to most semantic segmentation state-of-the-art methods.

The tradition of broadcast video is today complemented with user generated content, as portable devices support video coding. Similarly, computing is becoming ubiquitous, where Internet of Things (IoT) incorporate heterogeneous networks to communicate with personal and/or infrastructure devices. Irrespective, the emphasises is on bandwidth and processor efficiencies, meaning increasing the signalling options in video encoding. Consequently, assessment for pixel differences applies uniform cost to be processor efficient, in contrast the Human Visual System (HVS) has non-uniform sensitivity based upon lighting, edges and textures. Existing perceptual assessments, are natively incompatible and processor demanding, making perceptual video coding (PVC) unsuitable for these environments. This research allows existing perceptual assessment at the native level using low complexity techniques, before producing new pixel-base image quality assessments (IQAs). To manage these IQAs a framework was developed and implemented in the high efficiency video coding (HEVC) encoder. This resulted in bit-redistribution, where greater bits and smaller partitioning were allocated to perceptually significant regions. Using a HEVC optimised processor the timing increase was < +4% and < +6% for video streaming and recording applications respectively, 1/3 of an existing low complexity PVC solution. Future work should be directed towards perceptual quantisation which offers the potential for perceptual coding gain.

The thesis that perceptual experience is transparent has received considerable air-time in contemporary philosophy of mind and perception. Debate over its truth-value has reached an impasse. I diagnose this mired debate, and pursue a reformulation of the “transparency thesis” such that it can be more readily evaluated form the perspective of perceptual psychology and related subdisciplines. I argue that the empirical methods characteristic of these disciplines are important for evaluating the transparency thesis. Both historical and contemporary empirical results but substantial pressure on the transparency thesis.

The global hearing healthcare field is faced with two principal challenges. First, the demand for basic audiometric testing services far exceeds the capacity of trained clinicians even in high income countries, and this supply/demand mismatch is expected to worsen secondary to population aging. Next, once patients are identified as having a hearing loss, the treatments that are provided (hearing aids) do not sufficiently address their primary complaint, namely that they have trouble hearing in noisy environments. To begin to address the first problem, we executed a proof-of-concept study to ask whether mobile consumer electronics could be used to replace manually performed clinic-based testing with self-directed hearing measurements from home. We found that self-administered home hearing measurements were largely equivalent to standard clinical measures. To begin to address the second problem (hearing in noise challenges of patients), we performed three additional experiments. Inspired by promising findings of enhanced visual attention following action videogame training, we developed a closed-loop audiomotor training application and asked if playing a game that focused on tone in noise discriminations would provide generalized benefit for speech recognition in noise abilities. In young normally hearing adults, closed-loop training for one month provided a 12 percentage point improvement in speech understanding in noise scores. Next, we recruited older adults who wore hearing aids to play a similar closed-loop training game and observed a 10 percentage point enhancement of speech recognition in noise abilities secondary to gameplay, suggesting that this training could be coupled with standard treatments to improve patient outcomes. Finally, we studied the neurophysiological correlates of audiomotor signal in noise training in a rodent model, where we observed enhanced resistance to noise suppression in auditory cortical neurons following three months of training, perhaps contributing to the perceptual benefits that we observed in human subjects.

Product perceptual maps are visualizations of the perceptions of products by customers. They provide many advantages to businesses, such as identifying gaps in the market, understanding competition, and finding how new products fit into a market. Conventional product perceptual mapping methods exhibit limitations, particularly in capturing the highly nonlinear structure in product perceptual categories. Therefore, given only a set of images and triplet data representing product co-occurence by consumers, we propose and use a Gaussian mixture variational autoencoder (GMVAE) with triplet loss to create product embeddings. These product embeddings are then flattened into a 2D perceptual map able to be interpreted by human judgment. We test the GMVAE approach on three datasets: (1) a dataset of simple generated data; (2) the MNIST dataset, a dataset of handwritten digits; and (3) the Amazon Fashion dataset, a dataset of product images, product categories, and similar products. The GMVAE method is quantitatively evaluated on its ability to capture product "latent" categories, and qualitatively evaluated on the quality of its 2D perceptual maps compared with those produced by using a conventional perceptual mapping method. We find that across the experiments, the GMVAE method could reasonable capture "latent" perceptual product categories and is more effective than the conventional perceptual mapping baseline in correctly identifying and predicting latent product categories.

Aim : The purpose of this study was to examine the impact of simulated hearing loss on the acoustic contrasts between declarative questions and declarative statements and on the perception of speech intonation. A further purpose of the study was to investigate whether any such effects are universal or language specific. Method: Speakers included four native speakers of English and four native speakers of Mandarin and Taiwanese, with two female and two male adults in each group. Listeners included ten native English and ten native speakers of Mandarin and Taiwanese, with five female and five male adults in each group. All participants were aged between 19 and 55 years old. The speaker groups were asked to read a list of 28 phrases, with each phrase expressed as a declarative statement or a declarative question separately. These phrases were then filtered through six types of simulated hearing loss configurations, including three levels of temporal jittering for simulating a loss in neural synchrony, a high level of temporal jittering in combination with a high-pass or a low-pass filter that simulate falling and rising audiometric hearing loss configurations, and a vocoder processing procedure to simulate cochlear implant processing. A selection of acoustic measures was derived from the sentences and from some embedded vowels, including /i/, /a/, and /u/. The listener groups were asked to listen to the tokens in their native language and indicate if they heard a statement or a question. Results: The maximum fundamental frequency (F0) of the last syllable (MaxF0-last) and the maximum F0 of the remaining sentence segment (MaxF0-rest) were found to be consistently higher in declarative questions than in declarative statements. The percent jitter measure was found to worsen with simulated hearing loss as the level of temporal jittering increased. The vocoder-processed signals showed the highest percent jitter measure and the spread of spectral energy around the dominant pitch. Results from the perceptual data showed that participants in all three groups performed significantly worse with vocoder-processed tokens compared to the original tokens. Tokens with temporal jitter alone did not result in significantly worse perceptual results. Perceptual results from the Taiwanese group were significantly worse than the English group under the two filtered conditions. Mandarin listeners performed significantly worse with the neutral tone on the last syllable, and Taiwanese listeners performed significantly worse with the rising tone on the last syllable. Perception of male intonation was worse than female intonation with temporal jitter and high-pass filtering, and perception of female intonation was worse than male intonation with most temporal jittering conditions, including the temporal jitter and low-pass filtering condition. Conclusion: A rise in pitch for the whole sentence, as well as that in the final syllable, was identified as the main acoustic marker of declarative questions in all of the three languages tested. Perception of intonation was significantly reduced by vocoder processing, but not by temporal jitter alone. Under certain simulated hearing loss conditions, perception of intonation was found to be significantly affected by language, lexical tone, and speaker gender.

In this chapter, I argue that perceptual media like air or water are imperceptible. I show that, despite their lack of phenomenological features, perceptual media crucially affect what we see by selecting what is perceptually available to the perceiver. In the second part of the chapter, I argue that mirrors are visual media like air, water, and glass. According to this account, mirrors are transparent and invisible and cannot therefore have a distinctive look or appearance. In the last part of the chapter, I extend the general account of perceptual media to the sense organs themselves by showing that perceptual media not only include external entities causally involved in the perceptual process but also comprise the perceptual system itself.

Properties like shape, size, and colour exhibit perceptual constancy: they appear to remain constant throughout variations in the conditions under which they are perceived. A number of writers have suggested that “apparent properties”, mind-independent relational properties that vary with the perceptual conditions, play an essential role in explaining perceptual constancy. On this view, when we see, e.g. a penny from an oblique angle, we see the circularity of the penny by or in virtue of seeing a mind-independent relational apparent property (its elliptical look). This chapter argues that views which explain the perception of constant properties of objects by appealing to perception of mind-independent apparent properties are structurally similar to sense-datum theories of perception; as such, they face many of the same challenges. It concludes that apparent properties play at best a modest explanatory role, functioning as the objects of awareness when we direct our attention in the appropriate ways.

This chapter discusses the visual perception of hills. Hills look much steeper than they are. This chapter reviews current knowledge of the phenomenology of slant perception in relation to both functionalist and mechanistic accounts of this perceptual bias. Recent discoveries suggest that this misperception of the geometry of our environment may be related to useful biological information coding strategies with respect to not only slant but also other angular variables relevant to the biological measurement of surface layout. Even in the absence of hills, people misperceive the angular declination of their gaze systematically in ways that seem to contribute to the vertical expansion of the perceived environment.

In this initial chapter, the author establishes her framework for discussion of perceptual verbs like ‘look’, ‘see’, ‘seem’. Perceptual reports are particular speech acts made by utterances of sentences that contain a perceptual verb. More specifically, they are assertions made by utterances of these sentences. Perceptual reports assert how objects in the world and their perceptible property instances are perceived by subjects. A subset of these reports purport to assert how objects in the world and their visually perceptible property instances are visually perceived by subjects. This chapter is primarily concerned with the semantics of ‘seem’ and ‘look’, which—it is argued—subject-raising verbs. Subject-raising verbs function as intensional operators at the level of logical form, just like ‘it is possible’, ‘it was the case’, and ‘it might be the case’. The author’s main argument for the representational view rests on this fact about ‘seem’ and ‘look’.

Absolute identification is a deceptively simple task that has been the focus of empirical investigation and theoretical speculation for more than half a century. Since Miller’s (1956) seminal paper the puzzle of why people are severely limited in their capacity to accurately perform absolute identification has endured. Despite the apparent simplicity of absolute identification, many complicated and robust effects are observed in both response latency and accuracy, including capacity limitations, strong sequential effects and effects of the position of a stimulus within the set. Constructing a comprehensive theoretical account of these benchmark effects has proven difficult, and existing accounts all have shortcomings. We review classical empirical findings, as well as some newer findings that challenge existing theories. We then discuss a variety of theories, with a focus on the most recent proposals, make some broad conclusions about general classes of models, and discuss the challenges ahead for each class.

We can know some things about each others’ mental lives. The view that some of this knowledge is genuinely perceptual is getting traction. But the idea that we can see any of each other’s mental states themselves—the Simple Perceptual Hypothesis—remains unpopular. Very often the view that we can perceptually know, for example, that James is angry, is thought to depend either on our awareness of James’s expression or on the way James appears—versions of what I call the Expressive Hypothesis. The Expressive Hypothesis is intuitive. But in this chapter I argue that it does not allow us to do away with the thought that we sometimes perceive people’s mental states. I take my arguments to provide some tentative support for the Simple Perceptual Hypothesis.

This chapter argues that when we learn to recognize natural kinds, such as pine trees, this should be understood not in terms of kind properties coming to be represented in our perception, but simply in terms of a shift in our attention, which causes us to represent new low-level properties, such as colors, shapes, and textures. Susanna Siegel has argued that kinds, such as pine trees, can look phenomenally different to someone once that person becomes disposed to recognize them, and that the best explanation for this is that kind properties, such as being a pine tree, can become represented in perception. The chapter details an alternative explanation for the different look of the pine tree: a shift in one’s attentional pattern onto other low-level properties. Philosophers have alluded to this alternative before, but the chapter provides a comprehensive account of the view, drawing on the science of perceptual learning.

This chapter argues that there are widespread changes in perception due to learning, and that these changes are genuinely perceptual rather than post-perceptual. The argument is abductive. It draws on philosophical introspection spanning several hundred years, evidence from psychology, and evidence from neuroscience. The argument is that when we look at these three different levels of analysis, the best overall explanation for their results is that perceptual learning occurs, is fairly widespread, and is genuinely perceptual rather than post-perceptual. One key piece of the argument is that neuroscientific perceptual learning experiments repeatedly show that there are changes very early on in the primary sensory cortices after perceptual learning tasks. Coupled with behavioral evidence from psychology and convergent philosophical introspection on the perceptual learning cases, this chapter argues that perceptual learning is genuinely perceptual, rather than post-perceptual.

The design of image and video compression or transmission systems is driven by the need for reducing the bandwidth and storage requirements of the content while maintaining its visual quality. Therefore, the objective is to define codecs that maximize perceived quality as well as automated metrics that reliably measure perceived quality. One of the common shortcomings of traditional video coders and quality metrics is the fact that they treat the entire scene uniformly, assuming that people look at every pixel of the image or video. In reality, we focus only on particular areas of the scene. In this chapter, we prioritize the visual data accordingly in order to improve the compression performance of video coders and the prediction performance of perceptual quality metrics. The proposed encoder and quality metric incorporate visual attention and use a semantic segmentation stage, which takes into account certain aspects of the cognitive behavior of people when watching a video. This semantic model corresponds to a specific human abstraction, which need not necessarily be characterized by perceptual uniformity. In particular, we concentrate on segmenting moving objects and faces, and we evaluate the perceptual impact on video coding and on quality evaluation.

La fonología y la fonética son dos ramas de lingüística o niveles del lenguaje que se encargan de estudiar los sonidos de una determinada lengua. Por una parte, la fonología analiza la representación mental y abstracta de los sonidos desde la perspectiva funcional (fonemas) y, por otra parte, la fonética se enfoca en las características articulatorias, acústicas, perceptuales y físicas de los sonidos cuando este es producido (fonos - alófonos). En esta clase se explican algunas variaciones fonéticas entre el español de Chile y Costa Rica, así como también el desarrollo y la exploración de la fonética y fonología infantil desde la perspectiva de Hodson B. (Evaluación de Procesos Fonológicos "APP-S") utilizada en Costa Rica y la perspectiva de Pavez, Maggiolo y Coloma (Test para Evaluar Procesos de Simplificación Fonológica "TEPROSIF-R"), utilizada en Chile.
