A sound in a real space (e.g. a street or a room) is studied by acousticians as the relationship between an anechoic signal and the reverberant sound field. We define ‘anechoic signal’ a signal representing the pressure variation emitted by the sound source, while the ‘reverberant field’ is a field representing the sum of all the sound reflections of the environment in which the sound exists, delayed in time due to the positions of the sound source and the listener. The (...) auditory ability of detecting a sound and assigning it to a source depends both on the anechoic signal and the reverberant sound field. This relationship has been analysed in acoustic literature using the autocorrelation properties of the anechoic signals and objective metrics of the sound field, the last ones being the ‘room criteria’ described in ISO 3382. In this context, the ‘effective duration’ of the autocorrelation function (τe) has been proposed as key factor to ‘preferred’ values of several room criteria in relation to different kind of music signals. Relying on some similarities between the definition of ‘auditory objects’ and the sound detection in a reverberant space, this paper proposes the use of τe as a potential tool to study and catalogue auditory objects.

Over the last few decades, research on auditory perception has increased a great deal, treating a wide range of topics from different perspectives. Empirical research has provided a detailed account of sound perception in neurobiological terms. From a different perspective, the phenomenology of music has focused on the experience of auditory perception, highlighting the conditions that allow for the perception of sounds. Starting from the work by Giovanni Piana, I argue that sound perception is rooted in the experiential, (...) from which arise the biological and cultural structures that allow for it, with no priority of one structure over another, but rather interconnections and reciprocal conditioning. I then introduce ‘biological constraints’ and ‘phenomenological rules’, as the key notions that any conceptual investigation on sound perception should focus on in order to achieve a more comprehensive understanding of musical listening. Biological constraints are ‘a priori’ conditions and are mainly due to the biology of the human perceiving system. Phenomenological rules emerge from the constitution of the auditory object according to subjective experience. Combining knowledge from neurosciences and phenomenology, my work aims also at fostering an innovative approach to the aesthetics of music that takes advantage of empirical progress in current research on auditory perception.

The aim of this paper is, firstly, to identify the areas of conceptual confusion about the notion of auditory object that could benefit from a cooperation between philosophy and psychology of perception. Secondly, I try to clarify in what sense there may be individual entities that exist only in time focusing on auditory objects, and to establish what kind of relationship links the existence of such purely temporal entities with the existence of spatiotemporal entities such as bodies (...) or physical objects. Finally, a new definition of auditory object, conceived as a partially mind-dependent object, or Meinongian higher-order object based on inferiora, is discussed. (shrink)

This commentary focuses on the importance of auditory object processing for producing and comprehending human language, the relative lack of development of this capability in nonhuman primates, and the consequent need for hominid neurobiological evolution to enhance this capability in making the transition from protosign to protospeech to language.

This paper defends two theses about sensory objects. The more general thesis is that directly sensed objects are those delivered by sub-personal processes. It is shown how this thesis runs counter to perceptual atomism, the view that wholes are always sensed indirectly, through their parts. The more specific thesis is that while the direct objects of audition are all composed of sounds, these direct objects are not all sounds—here, a composite auditory object is a temporal sequence of sounds (...) (whereas a composite visual object is a spatial composite). Many composite objects are directly heard in the sense just mentioned. There is a great variety of such composite auditory objects—melodies, harmonies, sequences of phonemes, individual voices, meaning-carrying sounds, and so on. This diversity of auditory objects has an important application to aesthetics. Perceivers do not naturally or easily attend simultaneously to auditory objects that overlap in time. Yet, aesthetic appreciation depends on such an allocation of attention to overlapping objects. (shrink)

Our auditory experience involves the experience of auditory objects—sequences of distinct sounds, or parts of continuous sounds—that are experienced as grouped together into a single sound or “stream” of sounds. In this paper I argue that it is not possible to explain what it is to experience an auditory object as such—i.e. to experience a sequence of sounds as grouped—in purely auditory terms; rather, to experience an auditory object as such is to experience (...) a sequence of sounds as having been (apparently) produced by the same source.

What do we directly hear? In section I, I define direct perception, and outline the logical atomist way of attacking the question. I argue in section II that atomism fails. Then, in sections III-V, I propose that a better alternative to atomism is to revive and modernize another traditional empiricist doctrine: that we directly sense what the senses deliver to automatic (i.e., sub-personal) processes of learning.

: One can understand the word “object” as a concrete physical object or as that which is on the receiving end of a subject-object relation, namely, that entity which a particular cognitive state or process is “of.” These latter objects are determined by the way our sensory systems exploit the ways elements of the world impinge upon our bodily surfaces. Our visual system exploits light reflected off the surfaces of objects; therefore, the objects of our visual experiences (...) can be physical objects just sitting still. Our auditory system, on the other hand, exploits sound waves caused by impacts of one sort or another, and these are events. You don’t, strictly speaking, hear a billiard ball or a car: You hear a billiard ball hit another one, or a car drive past. (shrink)

Recent studies in human and nonhuman primates demonstrate that auditory objects, including speech sounds, are identified in anterior superior temporal cortex projecting directly to inferior frontal regions and not along a posterior pathway, as classically assumed. By contrast, the role of posterior temporal regions in speech and language remains largely unexplained, although a concept of vocal gestures may be helpful.

When you hear a person speaking in a familiar language you perceive the speech sounds uttered and the voice that produces them. How are speech sounds and voice related in a typical auditory experience of hearing speech in a particular voice? And how to conceive of the objects of such experiences? I propose a conception of auditory objects of speech perception as temporally structured mereologically complex individuals. A common experience is that speech sounds and the voice that produces (...) them appear united. I argue that the metaphysical underpinnings of the experienced unity of speech sounds and voices can be explained in terms of the mereological view on sounds and their sources. I also propose a psychological explanation of how we form and individuate the auditory objects of experiences of listening to speech in a particular voice. Voice characteristics enable determining the identity of auditory objects of speech sound perception by making some features of the speech signal stable and predictable. (shrink)

The aim of this special issue of Rivista di Estetica is to investigate the nature of the auditory object and its specific status as an object of perception.

It is widely accepted that there is a visual field, but the analogous notion of an auditory field is rejected by many philosophers on the grounds that the metaphysics or phenomenology of audition lack the necessary spatial or phenomenological structure. In this paper, I argue that many of the common objections to the existence of an auditory field are misguided and that, contrary to a tradition of philosophical scepticism about the spatiality of auditory experience, it is as (...) richly spatial as visual experience—and in some ways even more so. By carefully considering the spatiality and boundedness of audition, along with how sounds or their sources are experienced as occurring within the surrounding acoustic environment, we can gain a better understanding of (i) our auditory experience of space and (ii) the conditions for the existence of spatial sensory fields in general in a way that does not privilege vision over the other senses.

Background. Attending to goal-relevant information can leave us metaphorically ‘blind’ or ‘deaf’ to the next relevant information while searching among distracters. This temporal cost lasting for about a half a second on the human selective attention has been long explored using the attentional blink paradigm. Although there is evidence that certain visual stimuli relating to one’s area of expertise can be less susceptible to attentional blink effects, it remains unexplored whether the dynamics of temporal selective attention vary with expertise and (...) objects types in the auditory modality. Methods. Using the auditory version of the attentional blink paradigm, the present study investigates whether certain auditory objects relating to musical and perceptual expertise could have an impact on the transient costs of selective attention. In this study, expert cellists and novice participants were asked to first identify a target sound, and then to detect instrumental timbres of cello or organ, or human voice as a second target in a rapid auditory stream. Results. The results showed moderate evidence against the attentional blink effect for voices independent of participants’ musical expertise. Experts outperformed novices in their overall accuracy levels of target identification and detection, reflecting a clear benefit of musical expertise. Importanly, the musicianship advantage disappeared when the human voices served as the second target in the stream. Discussion. The results are discussed in terms of stimulus salience, the advantage of voice processing, as well as perceptual and musical expertise in relation to attention and working memory performances.

It is a commonly held view that auditory perception functions to tell us about sounds and their properties. In this paper I argue that this common view is mistaken and that auditory perception functions to tell us about the objects that are the sources of sounds. In doing so, I provide a general theory of auditory perception and use it to give an account of the content of auditory experience and of the nature of sounds.

Vision has been the primary focus of naturalistic philosophical research concerning perception and perceptual experience. Guided by visual experience and vision science, many philosophers have focused upon theoretical issues dealing with the perception of objects. Recently, however, hearing researchers have discussed auditory objects. I present the case for object perception in vision, and argue that an analog of object perception occurs in auditory perception. I propose a notion of an auditory object that is stronger (...) than just that of an intentional object of audition, but that does not identify auditory objects with the ordinary material objects we see. (shrink)

Some philosophers have argued that we do not hear sounds as located in the environment. Others have objected that this straightforwardly contradicts the phenomenology of auditory experience. And from this they draw metaphysical conclusions about the nature of sounds—that they are events or properties of vibrating surfaces rather than waves or sensations. I argue that there is a minimal, but recognizable, notion of audition to which this phenomenal objection does not apply. While this notion doesn’t correspond to our ordinary (...) notion of auditory experience, it does—in conjunction with our lack of an uncontroversial individuation of the senses and recent interest in distinctively multisensory features of perceptual experiences—raise the possibility of more expansive notions of audition, including some that do plausibly count as corresponding to our everyday notion of audition, that lack the spatial phenomenology cited in the objection. Until this possibility is ruled out, the phenomenal objection and metaphysical conclusions drawn from it remain inconclusive. (shrink)

The essay concerns the notion of realism and its relationship with the notion of perception. The ontological meaning of aesthetics as aisthesis is in fact in the non-amendable nature of perception. From this non-amendability the essay outlines four traces through which aisthesis leads to realism: “nonconceptual content”, “object”, “naivety”, “ontology”.

The auditory system is able to recognize auditory objects and is thought to form predictive models of them even though the acoustic information arriving at our ears is often imperfect, intermixed, or distorted. We investigated implicit regularity extraction for acoustically intact versus disrupted six-tone sound patterns via event-related potentials. In an exact-repetition condition, identical patterns were repeated; in two distorted-repetition conditions, one randomly chosen segment in each sound pattern was replaced either by white noise or by a wrong (...) pitch. In a roving-standard paradigm, sound patterns were repeated 1–12 times in a row before a new pattern occurred. The participants were not informed about the roving rule and had to detect rarely occurring loudness changes. Behavioral detectability of pattern changes was assessed in a subsequent behavioral task. Pattern changes elicited mismatch negativity and P3a, and were behaviorally detected above the chance level in all conditions, suggesting that the auditory system extracts regularities despite distortions in the acoustic input. However, MMN and P3a amplitude were decreased by distortions. At the level of MMN, both types of distortions caused similar impairments, suggesting that auditory regularity extraction is largely determined by the stimulus statistics of matching information. At the level of P3a, wrong-pitch distortions caused larger decreases than white-noise distortions. Wrong-pitch distortions likely prevented the engagement of restoration mechanisms and the segregation of disrupted from true pattern segments, causing stronger informational interference with the relevant pattern information.

The paper is concerned with arguing the existence of a relationship between the enactive theory of perception and aesthetics. One of the leading figures in the theory of enactment, Alva Noe, pointed out that the works of art constitute one of the keys to understand how perception and cognition realize their enactment onto reality. Art objects are, in fact, a very peculiar case of artefacts since they are considered as being able to quicken the living beings’ organization in their interaction (...) to the world. Do they create a different atmosphere? Do they “furnish” the surrounding habitat with new meanings? The paper argues that these are, of course, fundamental elements in the art’s action onto reality. As far as the subjective enactment of perception is concerned, together with power in designing life organization, art has arguably another original functions, that of building new “environs” where experience can meet reality under a different light and thus prepare the field for other creative contributions, both cultural and technological.

Attention is often conceived as a gateway to consciousness . Although endogenous spatial attention may be independent of conscious perception , exogenous spatial orienting seems instead to be an important modulator of CP . Here, we investigate the role of auditory alerting in CP in normal observers. We used a behavioral task in which phasic alerting tones were presented either at unpredictable or at predictable time intervals prior to the occurrence of a near-threshold visual target. We find, for the (...) first time in neurologically intact observers, that phasic alertness increases CP, both objectively and subjectively. This result is consistent with evidence showing that phasic alerting can ameliorate the spatial bias exhibited by visual neglect patients . The alerting network may increase the activity of fronto-parietal networks involved in top-down amplification required to bring a stimulus into consciousness. (shrink)

Voluntary stream segregation was investigated in cochlear implant users and normal-hearing listeners using a segregation-promoting objective approach which evaluated the role of spectral and amplitude-modulation rate separations on stream segregation and its build-up. Sequences of 9 or 3 pairs of A and B narrowband noise bursts were presented which differed in either center frequency of the noise band, the AM-rate, or both. In some sequences, the last B burst was delayed by 35 ms from their otherwise-steady temporal position. In the (...) other sequences, the last B bursts were temporally advanced from 0 to 10 ms. A single interval yes/no procedure was utilized to measure participants’ sensitivity in identifying delayed vs. no-delay sequences. A higher d′ value showed the higher ability to segregate the A and B subsequences. For NH listeners, performance improved with each spectral separation. However, for CI users, performance was only significantly better for the condition with the largest spectral separation. Additionally, performance was significantly poorer for the largest AM-rate separation than for the condition with no AM-rate separation for both groups. The significant effect of sequence duration in both groups indicated that listeners made more improvement with lengthening the duration of stimulus sequences, supporting the build-up effect. The results of this study suggest that CI users are less able than NH listeners to segregate NBN bursts into different auditory streams when they are moderately separated in the spectral domain. Contrary to our hypothesis, our results indicate that AM-rate separation may interfere with the segregation of streams of NBN. Additionally, our results add evidence to the literature that CI users build up stream segregation at a rate comparable to NH listeners, when the inter-stream spectral separations are adequately large.

Music-based interventions (MBI) have become increasingly widely adopted for dementia and related disorders. Previous research shows that music engages reward-related regions through functional connectivity with the auditory system, but evidence for the effectiveness of MBI is mixed in older adults with mild cognitive impairment (MCI) and Alzheimer’s disease (AD). This underscores the need for a unified mechanistic understanding to motivate MBIs. The main objective of the present study is to characterize the intrinsic connectivity of the auditory and reward (...) systems in healthy aging individuals with MCI, and those with AD. Using resting-state fMRI data from the Alzheimer’s Database Neuroimaging Initiative, we tested resting-state functional connectivity within and between auditory and reward systems in older adults with MCI, AD, and age-matched healthy controls (N = 105). Seed-based correlations were assessed from regions of interest (ROIs) in the auditory network (i.e., anterior superior temporal gyrus, posterior superior temporal gyrus, Heschl’s Gyrus), and the reward network (i.e., nucleus accumbens, caudate, putamen, and orbitofrontal cortex). AD individuals were lower in both within-network and between-network functional connectivity in the auditory network and reward networks compared to MCI and controls. Furthermore, graph theory analyses showed that the MCI group had higher clustering and local efficiency than both AD and control groups, whereas AD individuals had lo... (shrink)

Philosophers often state that the persistence of objects in vision is experienced differently than the persistence of sounds in audition. This difference is expressed by using metaphors from the metaphysical endurantism/perdurantism debate. For instance, it is claimed that only sounds are perceived as “temporally extended”. The paper investigates whether it is justified to characterize visually experienced objects and auditorily experienced sounds as different types of entities: endurants and perdurants respectively. This issue is analyzed from the perspective of major specifications of (...) the endurance/perdurance distinction connected, inter alia, with the notions of temporal parts and temporal localization. It is argued that it is unjustified to characterize visually experienced objects and auditorily experienced sounds as different types of entities in respect of how they persist. On the other hand, the apparent difference in the way of persisting can be explained by the presence of contingent differences between typical visual and auditory experiences. (shrink)

The article aims to concretize the phenomenological account concerning the problem of an auditory image. The author considers auditory imagery as a scientific object and compares different treatments of the problem to fix the potential and advantages of its phenomenological interpretation. In the first stage of the study, the author distinguishes the key characteristics of the image by means the lexical analysis. This is the perceptual (predominantly visual) nature of an image, integrality, and essentiality (image as an (...) idea). In the second stage, the understandings of the mental and auditory imagery in physiology, experimental psychology, music psychology, musicology, and interdisciplinary studies are described. In the third stage, the peculiar phenomenological ways of the comprehension of an auditory image are revealed. The phenomenological interest is to pick out consciousness which perceiving of an image equally from the process of perceiving and from entailing in an image. The specific phenomenological stance is placing an auditory image on the bound of transcendent (the process of perceiving) and immanent (an image that is already perceived). The auditory image is conceived as the unity of Modi of its givenness. Most fecks of this Modi are original, they cannot be transferred into other science scopes: they are the interconnection of all moments of the temporal unfolding, self-organization in the time, self-referentiality, non-semanticity, periodicity/randomness, eventuality, quasi-embodiment (physicality). Solely phenomenological problems are problems of the constitution of an auditory image, its life-horizon, intersubjectivity, and regional matching. The author infers that phenomenology does not conceive auditory image as sustained auditory representation, associated with acoustic memory. Its perceptual nature does not play a key role here. Moreover, the perceptual-semantic duality of the image is not fixed by the phenomenological description. The phenomenological approach is unique because it researches auditory data exhaustively but does not use semantic and referential analysis of them. The main feature of phenomenological description is the focus on the unity of auditory image: All the elements of auditory data are interpreted in their synthesis as the different levels of the unity of hearing image. Thus, the phenomenological approach as a whole is the most promising for comprehending such a dominant quality of the auditory image as integrality. (shrink)

Much of the philosophical work on perception has focused on vision. Recently, however, philosophers have begun to correct this ‘tunnel vision’ by considering other modalities. Nevertheless, relatively little has been written about the chemical senses—olfaction and gustation. The focus of this paper is olfaction. In light of new physiological and psychophysical research on olfaction, I consider whether olfactory experience is object-based. In particular, I explore the claim that “odor objects” constitute sensory individuals. It isn’t obvious—at least at the outset—whether (...) they meet the widely accepted principles of object individuation and recognition at work in the visual and auditory cases. Among the general issues I consider, then, is whether these traditional principles form necessary, or simply sufficient, conditions on object perception. As we see, at the very least, considering the object-recognition model of olfaction challenges us to look more closely at well-entrenched models of object perception. But the payoff of doing so is high. We not only learn something about a modality that philosophers have historically neglected; by asking new questions and challenging old assumptions, we also further our understanding of perception in general.

Object perception deploys a suite of perceptual capacities that constrains attention, guides reidentification, subserves recognition, and anchors demonstrative thought. Objects for perception—perceptual objects—are the targets of such capacities. Characterizing perceptual objects for multisensory perception faces two puzzles. First is the diversity of objects across sensory modalities. Second is the unity of multisensory perceptual objects. This paper resolves the puzzles. Objects for perception are structured mereologically complex individuals. Perceptual objects are items that bear perceptible features and have perceptible parts arranged (...) to form a unified whole. This circumscribes the targets of object perception where neutral talk concerning intentional objects and objects of perception cannot. Nonetheless, it is more permissive than identifying perceptual objects with material bodies, which excludes too much and leans too heavily on vision. The account thus is tailored to capture the role of objects in perception beyond vision: tactual, auditory, and olfactory objects are individuals with differing structures. Its flexibility also enables the account to accommodate shared objects for multisensory perception: multisensory perceptual objects are mereologically complex individuals with hybrid structure. For instance, one can bimodally perceive a common whole with parts accessible to one but not both modalities. Each sense provides a partial perspective on a complex whole that is perceptible through the coordinated use of multiple senses. Understanding perceptual objects as structured mereologically complex individuals thus provides a theoretically useful notion of an object for multisensory perception that resolves the puzzles of diversity and of unity.

Whilst arguing for sounds as repeatable objects does not seem suitable to our auditory experience, considering them as events can then help us understand some of their main features. In this sense, sounds are events happening to material objects; they have a beginning and an end; they are ephemeral entities that we cannot grasp as ordinary objects. Nevertheless, supporters of event theory usually focus on the autonomous status that sounds manifest from the things in the world. Conversely, when we (...) hear sounds, we hear what and where they are sounding even in those theories that I will call detached-sound theories; in hearing them we hear how different materials create different sounds. Within the different positions of the event theory to pure-event or acousmatic proposal, the importance and role that the material has in the creation of diverse sounds does not always seem to be recognized. In this paper, I therefore aim to show how the materiality of resonating bodies and objects is given in all forms of auditory experience, not until analyzed the differences between object and event accounts in the philosophy of sound.

Auditory-guided vocal learning is a mechanism that operates both in humans and other animal species making us capable to imitate arbitrary sounds. Both auditory memories and auditory feedback interact to guide vocal learning. This may explain why it is easier for humans to imitate the pitch of a human voice than the pitch of a synthesized sound. In this study, we compared the effects of two different feedback modalities in learning pitch-matching abilities using a synthesized pure tone (...) in 47 participants with no prior music experience. Participants were divided into three groups: a feedback group receiving real-time visual feedback of their pitch as well as knowledge of results; an equal-timbre group receiving additional auditory feedback of the target note with a similar timbre to the instrument being used ; and a control group practicing without any feedback or knowledge of results. An additional fourth group of violin experts performed the same task for comparative purposes. All groups were posteriorly evaluated in a transfer phase. Both experimental groups improved their intonation abilities with the synthesized sound after receiving feedback. Participants from the equal-timber group seemed as capable as the feedback group of producing the required pitch with the voice after listening to the human voice, but not with the violin. In addition, only participants receiving real-time visual feedback learned and retained in the transfer phase the mapping between the synthesized pitch and its correspondence with the produced vocal or violin pitch. It is suggested that both the effect of an objective external reward, together with the experience of exploring the pitch space with their instrument in an explicit manner, helped participants to understand how to control their pitch production, strengthening their schemas, and favoring retention.

The predictable rhythmic structure is important to most ecologically relevant sounds for humans, such as is found in the rhythm of speech or music. This study addressed the question of how rhythmic predictions are maintained in the auditory system when there are multiple perceptual interpretations occurring simultaneously and emanating from the same sound source. We recorded the electroencephalogram (EEG) while presenting participants with a tone sequence that had two different tone feature patterns, one based on the sequential rhythmic variation (...) in tone duration and the other on sequential rhythmic variation in tone intensity. Participants were presented with the same sound sequences and were instructed to listen for the intensity pattern (ignore fluctuations in duration) and press a response key to detected pattern deviants (attend intensity pattern task); to listen to the duration pattern (ignore fluctuations in intensity) and make a button press to duration pattern deviants (attend duration pattern task), and to watch a movie and ignore the sounds presented to their ears (attend visual task). Both intensity and duration patterns occurred predictably 85% of the time, thus the key question involved evaluating how the brain treated the irrelevant feature patterns (standards and deviants) while performing an auditory or visual task. We expected that task-based feature patterns would have a more robust brain response to attended standards and deviants than the unattended feature patterns. Instead, we found that the neural entrainment to the rhythm of the standard attended patterns had similar power to the standard of the unattended feature patterns. In addition, the infrequent pattern deviants elicited the event-related brain potential called the mismatch negativity component (MMN). The MMN elicited by task-based feature pattern deviants had a similar amplitude to MMNs elicited by unattended pattern deviants that were unattended because they were not the target pattern or because the participant ignored the sounds and watched a movie. Thus, these results demonstrate that the brain tracks multiple predictions about the complexities in sound streams and can automatically track and detect deviations with respect to these predictions. This capability would be useful for switching attention rapidly among multiple objects in a busy auditory scene. (shrink)

Through hearing we learn about source events: events in which objects move or interact so that they vibrate and produce sound waves, such as when they roll, collide, or scrape together. It is often claimed that we do not simply hear sounds and infer what event caused them, but hear source events themselves, through hearing sounds. Here I investigate how the idea that we hear source events should be understood, with a focus on how hearing an event relates to hearing (...) the objects involved in that event. I argue that whereas we see events such as rollings and collisions by seeing objects move through space, this cannot be how we hear them, and go on to examine two other possible models. On the first, we hear events but not their participant objects. On the second, to hear an event is to hear the appearance of an object to change. I argue that neither is satisfactory and endorse a third option: to hear a source event is to hear an object as extending through time. (shrink)

In Berkeley’s writings the topic of light is discussed in two different ways, within a theory of perception and within a metaphysics of nature of a Platonic stamp. In his first work, the original Essay for a New Theory of Vision, light and colours are regarded as condition and object of vision; they are examined as contents of visual perception distinct from tangible perception. Light will be dealt with in a completely different manner in Berkeley’s last work, Siris, in (...) which a spiritualistic reading of the natural world is superimposed on modern science in general and on Newtonian physics in particular. In Siris, light is the instrument by which the causal activity of divine Intellect orders and permeates the natural world. A detailed analysis of the topic of light in the two aforementioned contexts shows inconsistencies and strained interpretations which derive from the apologetic use of the theory of vision in Berkeley’s early immaterialism and from the multi-layered and confused speculations of his late Siris. On the whole, Berkeley conceives light within the idealistic frame inherited from Platonic metaphysics of light; however, the specific themes examined in the Essay for a New Theory of Vision and in Siris derive from acquisitions of modern science, and are recast within a spiritualistic interpretation which intended both to neutralize scientific ideas through their phenomenistic reading and to exploit them for apologetic ends.

Objects are central in visual, auditory, and tactual perception. But what counts as a perceptual object? I address this question via a structural unity schema, which specifies how a collection of parts must be arranged to compose an object for perception. On the theory I propose, perceptual objects are composed of parts that participate in causally sustained regularities. I argue that this theory falls out of a compelling account of the function of object perception, and illustrate (...) its applications to multisensory perception. I also argue that the account avoids problems faced by standard views of visual and auditory objects. (shrink)
