Available in PDF, EPUB and Kindle. Book excerpt: Paying attention is something we are all familiar with and often take for granted, yet the nature of the operations involved in paying attention is one of the most profound mysteries of the brain. This book contains a rich, interdisciplinary collection of articles by some of the pioneers of contemporary research on attention. Central themes include how attention is moved within the visual field; attention's role during visual search, and the inhibition of these search processes; how attentional processing changes as continued practice leads to automatic performance; how visual and auditory attentional processing may be linked; and recent advances in functional neuro-imaging and how they have been used to study the brain's attentional network

Download or read book The Causes Distinctiveness and Effects of Object based Attention written by Cameron T. Ellis and published by . This book was released on 2014 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Attention acts as a filter to expedite and accentuate the processing of relevant information. This thesis focused on understanding object-based attention, a form of visual attention in which objects are selectively filtered and prioritised. In Chapter 2, using the 'rectangle paradigm' of Egly, Driver and Rafal (1994), a measure of object-based attention was acquired by comparing the differences in reaction times to targets in cued versus uncued objects. While holding the duration of object exposure constant, when the objects appear before the cue does not affect object-based attention. Hence this result combined with other research would suggest that it is not about when the objects appear but rather how long the objects are present for that determines object-based attention. Chapter 3 used a similar method to Chapter 2 under EEG conditions to dissociate the neural basis of space- and object-based attention. It was found that space-based attention modulated the P2 component in the ERP to the target, the N1 component to the cue and the N1 component to the object. Object-based attention only affected the N1 component to the rectangle onset. Crucially, both space- and object-based attention correlated with altered processing of object information (the object onset). However these correlations with the object can be dissociated by their different directionalities and localisations. Therefore space- and object-based attention appear to represent distinct mechanisms. Chapters 2 and 3 together showed that oscillations in the magnitude of space- and object-based attention occur as the time between the cue and target changes, supporting previous work (Fiebelkorn, Saalmann, & Kastner, 2013). Chapter 4, using a motion induced blindness paradigm (Bonneh, Cooperman, & Sagi, 2001), reports that two connected circles can form an object totally outside of awareness. Whilst, the objects that formed likely produced object-based attention this was nonetheless insufficient to bring a previously unconscious stimulus into awareness. Thus object-based attention is insufficient for awareness. Overall this thesis advances the field of object-based attention and establishes a clear role for object-based attention in the visual system.
Download or read book Physiological Evidence of Interactive Object based and Space based Attention Mechanisms written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual attention has been likened to a spotlight that enhances both attended and nearby objects. However, experiments employing overlapping stimuli have shown that individuals are able to attend selectively to one object while suppressing the other. These data are problematic for spotlight theories of selection, suggesting that under some circumstances, selection may also be made with respect to objects rather than spatial location. It has been suggested that these two types of selection are achieved by a single mechanism by which the attentional spotlight conforms to the boundary of an object. Alternatively, space- and object-based selection may be independent, but mutually supporting systems. The present set of experiments examined the relationship between object-based and space-based selection using event-related potentials (ERPs). Previous research has shown that attention to spatial location results in an enhancement of the P1 and N1 components of the ERP. This pattern is associated with spatial attention and is not seen when observers are attending to non-spatial attributes, such as color or shape. In the object-based attention condition, ERPs were collected in response to flashes on attended objects, unattended overlapping objects, and unattended objects at far locations. In the space-based attention condition, ERPs were elicited by the same flashes occurring in empty locations. Both space-based and object-based ERPs produced P1 and N1 components, but only the space-based ERPs showed an attentional effect on P1 amplitude. The attentional effect on the parietal N1 was nearly identical for both object- and space-based ERPS. These data suggest that space and object-based attention may be separate, but interactive systems.

Download or read book Things and Places written by Zenon W. Pylyshyn and published by MIT Press. This book was released on 2007 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author argues that the process of incrementally constructing perceptual representations, solving the binding problem (determining which properties go together), and, more generally, grounding perceptual representations in experience arise from the nonconceptual capacity to pick out and keep track of a small number of sensory individuals. He proposes a mechanism in early vision that allows us to select a limited number of sensory objects, to reidentify each of them under certain conditions as the same individual seen before, and to keep track of their enduring individuality despite radical changes in their properties--all without the machinery of concepts, identity, and tenses. This mechanism, which he calls FINSTs (for "Fingers of Instantiation"), is responsible for our capacity to individuate and track several independently moving sensory objects--an ability that we exercise every waking minute, and one that can be understood as fundamental to the way we see and understand the world and to our sense of space.

Download or read book Inattentional Blindness written by Arien Mack and published by MIT Press. This book was released on 1998 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arien Mack and Irvin Rock make the radical claim that there is no conscious perception of the visual world without attention to it. Many people believe that merely by opening their eyes, they see everything in their field of view; in fact, a line of psychological research has been taken as evidence of the existence of so-called preattentional perception. In Inattentional Blindness, Arien Mack and Irvin Rock make the radical claim that there is no such thing -- that there is no conscious perception of the visual world without attention to it. The authors present a narrative chronicle of their research. Thus, the reader follows the trail that led to the final conclusions, learning why initial hypotheses and explanations were discarded or revised, and how new questions arose along the way. The phenomenon of inattentional blindness has theoretical importance for cognitive psychologists studying perception, attention, and consciousness, as well as for philosophers and neuroscientists interested in the problem of consciousness.

Book excerpt: Interdisciplinary perspectives on the feature of conscious life that scaffolds every act of cognition: subjective time. Our awareness of time and temporal properties is a constant feature of conscious life. Subjective temporality structures and guides every aspect of behavior and cognition, distinguishing memory, perception, and anticipation. This milestone volume brings together research on temporality from leading scholars in philosophy, psychology, and neuroscience, defining a new field of interdisciplinary research. The book's thirty chapters include selections from classic texts by William James and Edmund Husserl and new essays setting them in historical context; contemporary philosophical accounts of lived time; and current empirical studies of psychological time. These last chapters, the larger part of the book, cover such topics as the basic psychophysics of psychological time, its neural foundations, its interaction with the body, and its distortion in illness and altered states of consciousness.

Download or read book Informative Hypotheses written by Herbert Hoijtink and published by CRC Press. This book was released on 2011-10-26 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: When scientists formulate their theories, expectations, and hypotheses, they often use statements like: ``I expect mean A to be bigger than means B and C"; ``I expect that the relation between Y and both X1 and X2 is positive"; and ``I expect the relation between Y and X1 to be stronger than the relation between Y and X2". Stated otherwise, they formulate their expectations in terms of inequality constraints among the parameters in which they are interested, that is, they formulate Informative Hypotheses. There is currently a sound theoretical foundation for the evaluation of informative hypotheses using Bayes factors, p-values and the generalized order restricted information criterion. Furthermore, software that is often free is available to enable researchers to evaluate the informative hypotheses using their own data. The road is open to challenge the dominance of the null hypothesis for contemporary research in behavioral, social, and other sciences.

Available in PDF, EPUB and Kindle. Book excerpt: WINNER OF THE 2014 BRAIN PRIZE From the acclaimed author of Reading in the Brain and How We Learn, a breathtaking look at the new science that can track consciousness deep in the brain How does our brain generate a conscious thought? And why does so much of our knowledge remain unconscious? Thanks to clever psychological and brain-imaging experiments, scientists are closer to cracking this mystery than ever before. In this lively book, Stanislas Dehaene describes the pioneering work his lab and the labs of other cognitive neuroscientists worldwide have accomplished in defining, testing, and explaining the brain events behind a conscious state. We can now pin down the neurons that fire when a person reports becoming aware of a piece of information and understand the crucial role unconscious computations play in how we make decisions. The emerging theory enables a test of consciousness in animals, babies, and those with severe brain injuries. A joyous exploration of the mind and its thrilling complexities, Consciousness and the Brain will excite anyone interested in cutting-edge science and technology and the vast philosophical, personal, and ethical implications of finally quantifying consciousness.

Download or read book The Sense of Agency written by Patrick Haggard and published by Oxford University Press. This book was released on 2015-08-27 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agency has two meanings in psychology and neuroscience. It can refer to one's capacity to affect the world and act in line with one's goals and desires--this is the objective aspect of agency. But agency can also refer to the subjective experience of controlling one's actions, or how it feels to achieve one's goals or affect the world. This subjective aspect is known as the sense of agency, and it is an important part of what makes us human. Interest in the sense of agency has exploded since the early 2000s, largely because scientists have learned that it can be studied objectively through analyses of human judgment, behavior, and the brain. This book brings together some of the world's leading researchers to give structure to this nascent but rapidly growing field. The contributors address questions such as: What role does agency play in the sense of self? Is agency based on predicting outcomes of actions? And what are the links between agency and motivation? Recent work on the sense of agency has been markedly interdisciplinary. The chapters collected here combine ideas and methods from fields as diverse as engineering, psychology, neurology, neuroscience, and philosophy of mind, making the book a valuable resource for any student or researcher interested in action, volition, and exploring how mind and brain are organized.
