What is attention? Attention is often seen as a subject matter for the hard sciences of cognitive and brain processes, and is understood in terms of sub-personal mechanisms and processes. Correspondingly, there still is a stark contrast between the central role attention plays for the empirical investigation of the mind in psychology and the neurosciences, and its relative neglect in philosophy. Yet, over the past years, several philosophers have challenged the standard conception. A number of interesting philosophical questions concerning the (...) nature of attention arise. This article provides an introduction to contemporary debates concerning these questions. In particular, it discusses the question of how the pre-theoretic conception of attention might be reconciled with a scientific conception, arguments that provide support for an anti-reductivist theory of attention, and sketches several recent anti-reductivist theories and their inter-relations.

It is possible to consider attention as the modulating dimension of consciousness. Understood in this sense, attention can be a privileged theme for relating the first person point of view (conceived as a psycho-phenomenology inspired by the work of Husserl) to the experimental sciences (e.g. psychology, neuropsychology, etc.), which have done a great deal of work on attention. This article will take up in succession some different points of view regarding the status of attention and its structure (e.g. static aspects). (...) It will also consider the dynamic of attention from a micro-genetic point of view as well as a functional point of view. The final section will seek to show not only the unique and original contributions of each perspective, but also each perspective''s limitations and biases. (shrink)

The surviving writings of Epicurus and his followers contain several references to epibolê – a puzzling notion that does not receive discussion in the extant Epicurean texts. There is no consensus about what epibolê is, what it is of, and what it operates on and, moreover, its epistemological status is controversial. This article aims to address these issues in both Epicurus and later Epicurean authors. Part One focuses mainly on Epicurus’ Letter to Herodotus, highlights a crucial distinction hitherto unnoticed in (...) the literature between two different types of epibolê, and brings out he necessary connection between epibolê and the application of the criteria of truth. Part Two considers the philosophical merits of the traditional interpretation of epibolê as projection and/or attention. Part Three examines the two aforementioned types of epibolê in Lucretius and Philodemus and shows that these authors accord epibolê paramount epistemological and ethical importance. (shrink)

The effect of attention on perceived brightness and contrast was investigated in eight experiments. Attention was manipulated by engaging observers in an attention-demanding concurrent task or by directing attention to a location with a peripheral cue. In all of the dual-task manipulations, attention reduced the variability of responses. However, attention did not affect the brightness of stimuli, nor did it affect the amount of simultaneous brightness contrast. Results with peripheral location cues were similar; however, the effect of attention in these (...) experiments could be attributed to nonperceptual factors. The metaphorical “spotlight” of attention reduces observers' uncertainty about the brightness of a stimulus, but it does not “illuminate” in terms of brightness or contrast. (shrink)

Descartes is widely portrayed as the arch proponent of “the epistemological transparency of thought” (or simply, “Transparency”). The most promising version of this view—Transparency-through-Introspection—says that introspecting (i.e., inwardly attending to) a thought guarantees certain knowledge of that thought. But Descartes rejects this view and provides numerous counterexamples to it. I argue that, instead, Descartes’s theory of self-knowledge is just an application of his general theory of knowledge. According to his general theory, certain knowledge is acquired only through clear and distinct (...) intellection. Thus, in his view, certain knowledge of one’s thoughts is acquired only through clear and distinct intellection of one’s thoughts. Introspection is a form of intellection and it can be clear and distinct. Ordinarily, however, introspection isn’t clear and distinct but is instead confused with dubitable perceptions of bodies. To make introspection clear and distinct, we need to “sharply separate” it from all perceptions of bodies by doubting all perceptions of bodies. Without such radical doubt, introspection remains confused and we lack certain knowledge not just of the specific features of our thoughts, but even of the minimal claim that a thought exists. Far from being the high priest of Transparency, Descartes is radically opposed to it. (shrink)

How do humans manage to keep track of a gradually changing object or person as the same persisting individual despite the fact that the extraction of information about this individual must often rely on heterogeneous information sources and heterogeneous tracking methods? The article introduces the Empirical Tracking of Individuals theory to address this problem. This theory proposes an analysis of the concept of integrated tracking, which refers to the capacity to acquire, store, and update information about the identity and location (...) of individuals in our environment. It hypothesizes that certain functions of attention are a key to explaining how the cognitive flexibility of the human mind overcomes the heterogeneity of sources and methods in integrated tracking. At least two premises lend support to this hypothesis. First, heterogeneity of tracking sources is overcome by the combination of information from multiple perceptual modalities and a phenomenon of multisensory 'transparency'. Second, heterogeneity of tracking sources and methods may also be overcome by inferences that combine information across domains to acquire reasons to believe propositions about the target's location and identity.

There is a strong philosophical intuition that direct study of the brain can and will constrain the development of psychological theory. When this intuition is tested against case studies on the neurophysiology and psychology of perception and memory, it turns out that psychology has led the way toward knowledge of neurophysiology. An abstract argument is developed to show that psychology can and must lead the way in neuroscientific study of mental function. The opposing intuition is based on mainly weak arguments (...) about the fundamentality or objectivity of physics or physiology in relation to psychology. -/- Philosophy of Science, Vol. 67, Supplement.

I argue that a study of the Nicomachean Ethics and of the Parva Naturalia shows that Aristotle had a notion of attention. This notion captures the common aspects of apparently different phenomena like perceiving something vividly, being distracted by a loud sound or by a musical piece, focusing on a geometrical problem. For Aristotle, these phenomena involve a specific selectivity that is the outcome of the competition between different cognitive stimuli. This selectivity is attention. I argue that Aristotle studied the (...) common aspects of the physiological processes at the basis of attention and its connection with pleasure. His notion can explain perceptual attention and intellectual attention as voluntary or involuntary phenomena. In addition, it sheds light on how attention and enjoyment can enhance our cognitive activities. (shrink)

Psychology has been the significant discipline since the time of antiquity which becomes more consolidated during the medieval age of Islam. It had a strong foundation in the professional writings of polymaths from the Islamic Middle Ages that were eventually transmitted to the West. However, the unique psychological contributions of these medieval polymaths remained largely unexplored. Despite the growing interest in their work, which is partly due to Islamic psychology, only a handful of them have been investigated for their unique (...) psychological contributions, and a complete examination of psychological work has not been done, separately from an Islamic perspective. The majority of them have only been examined in terms of their medical value, neglecting psychological issues in their all-encompassing approaches to care. Therefore, it was quintessential to extensively explore all those scholars who contributed to the various fields of psychology and to fill a gap of information that has been left by the previous researchers.

This volume, including sixteen contributions, analyses ancient and medieval theories of intentionality in various contexts: perception, imagination, and intellectual thinking. It sheds new light on classical theories and examines neglected sources, both Greek and Latin.

This book is a succinct introduction to the orienting of attention.

Orthodox interpretations of Sperling‘s partial report paradigm support the idea that there is substantially more in our streams of consciousness than we can attend to or recall. I propose an alternative, postdictive interpretation which fails to support any such conclusion. This account is defended at greater length in my ‗Perception and iconic memory‘. Here I focus on the role ascribed to attention by the rival interpretations. I argue that orthodox accounts fail to assign a plausible role to attention. In contrast, (...) I suggest a novel way in which heterodox, postdictive account can assign attention a plausible role. We should therefore prefer such accounts over their orthodox rivals. Consequently, Sperling‘s paradigm fails to probe the true extent of conscious awareness unfettered by limitations on attention or memory. (shrink)

This paper defends and develops the structuring account of conscious attention: attention is the conscious mental process of structuring one’s stream of consciousness so that some parts of it are more central than others. In the first part of the paper, I motivate the structuring account. Drawing on a variety of resources I argue that the phenomenology of attention cannot be fully captured in terms of how the world appears to the subject, as well as against an atomistic conception of (...) attention. In the second part of the paper, I show how the structuring account can be made precise: attention causes and causally sustains phenomenal relations to hold between the parts of the stream of consciousness; most importantly the relation of one part being peripheral to another. I end by pointing out consequences for both the scientific study of attention as well as for several areas of central philosophical interest. (shrink)

Clear and distinct perception is the centrepiece of Descartes’s philosophy — it is the source of all certainty — but what does he mean by ‘clear’ and ‘distinct’? According to the prevailing approach, what it means for a perception to be clear is that its content has a certain objective property, like truth. I argue instead that clarity is at least partly a subjective, phenomenal quality whereby a content is presented as true to the perceiving subject. Clarity comes in degrees. (...) Any weak degree of clarity, available to the senses, can be merely subjective, since what it presents as true may not actually be true. But complete clarity, available to intellectual perception, has an objective dimension, since what it presents as true is always some truth, some bit of reality. Further, I argue that the other perceptual qualities that Descartes identifies — obscurity, confusion, and distinctness — are all defined in terms of clarity. Of particular note is the fact that distinctness is not a positive feature to be added to clarity: a distinct perception is just a completely clear perception. (shrink)
