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 Encyclopedia of Perception written by E. Bruce Goldstein and published by SAGE. This book was released on 2010 with total page 1281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the ease with which we perceive, many people see perception as something that "just happens." However, even seemingly simple perceptual experiences involve complex underlying mechanisms, which are often hidden from our conscious experience. These mechanisms are being investigated by researchers and theorists in fields such as psychology, cognitive science, neuroscience, computer science, and philosophy. A few examples of the questions posed by these investigations are, What do infants perceive? How does perception develop? What do perceptual disorders reveal about normal functioning? How can information from one sense, such as hearing, be affected by information from another sense, such as vision? How is the information from all of our senses combined to result in our perception of a coherent environment? What are some practical outcomes of basic research in perception? These are just a few of the questions this encyclopedia will consider, as it presents a comprehensive overview of the field of perception for students, researchers, and professionals in psychology, the cognitive sciences, neuroscience, and related medical disciplines such as neurology and ophthalmology.

Available in PDF, EPUB and Kindle. Book excerpt: In order to produce coherent behaviour in a complex world, forms of visual attention are necessary in order for us to select appropriate objects for action. Over the past ten years, there have been considerable advances in research into visual attention, with many of these advances linked to interdisciplinary research in experimental psychology, neuropsychology, neurophysiology and functional imaging. This work has begun to allow us to understand not only the functional properties of visual attention, but also how attentional processes are localized in the brain: the cognitive neuroscience of visual attention. This special issue draws together research from leading figures in this field, to highlight recent progress in understanding how selective processes operate in perception and action.

Download or read book The Oxford Handbook of Perceptual Organization written by Johan Wagemans and published by OUP Oxford. This book was released on 2015-08-21 with total page 1121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perceptual organization comprises a wide range of processes such as perceptual grouping, figure-ground organization, filling-in, completion, perceptual switching, etc. Such processes are most notable in the context of shape perception but they also play a role in texture perception, lightness perception, color perception, motion perception, depth perception, etc. Perceptual organization deals with a variety of perceptual phenomena of central interest, studied from many different perspectives, including psychophysics, experimental psychology, neuropsychology, neuroimaging, neurophysiology, and computational modeling. Given its central importance in phenomenal experience, perceptual organization has also figured prominently in classic Gestalt writings on the topic, touching upon deep philosophical issues regarding mind-brain relationships and consciousness. In addition, it attracts a great deal of interest from people working in applied areas like visual art, design, architecture, music, and so forth. The Oxford Handbook of Perceptual Organization provides a broad and extensive review of the current literature, written in an accessible form for scholars and students. With chapter written by leading researchers in the field, this is the state-of-the-art reference work on this topic, and will be so for many years to come.
Download or read book Peripheral Interaction written by Saskia Bakker and published by Springer. This book was released on 2016-03-29 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computing devices have become ever more present in our everyday environments, however embedding these technologies into our routines has remained a challenge. This book explores the novel theory of peripheral interaction to rectify this. This theory examines how interactive systems can be developed in such a way to allow people to seamlessly interact with their computer devices, but only focus on them at relevant times, building on the way in which people effortlessly divide their attention over several everyday activities in day to day life. Capturing the current state of the art within the field, this book explores the history and foundational theories of peripheral interaction, discusses novel interactive styles suitable for peripheral interaction, addresses different application domains which can benefit from peripheral interaction and presents visions of how these developments can have a positive impact on our future lives. As such, this book’s aim is to contribute to research and practice in fields such as human-computer interaction, ubiquitous computing and Internet of Things, a view on how interactive technology could be redesigned to form a meaningful, yet unobtrusive part of people’s everyday lives. Peripheral Interaction will be highly beneficial to researchers and designers alike in areas such as HCI, Ergonomics and Interaction Design.

Download or read book Attentional Capture written by Bradley S. Gibson and published by . This book was released on 2008 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The notion that certain mental or physical events can capture attention has been one of the most enduring topics in the study of attention owing to the importance of understanding how goal-directed and stimulus-driven processes interact in perception and cognition. Despite the clear theoretical and applied importance of attentional capture, a broad survey of this field suggests that the term "capture" means different things to different people. In some cases, it refers to covert shifts of spatial attention, in others involuntary saccades, and in still others general disruption of processing by irrelevant stimuli. The properties that elicit "capture" can also range from abruptly onset or moving lights, to discontinuities in textures, to unexpected tones, to emotionally valenced words or pictures, to directional signs and symbols. Attentional capture has been explored in both the spatial and temporal domains as well as the visual and auditory modalities. There are also a number of different theoretical perspectives on the mechanisms underlying "capture" (both functional and neurophysiological) and the level of cognitive control over capture. This special issue provides a sampling of the diversity of approaches, domains, and theoretical perspectives that currently exist in the study of attentional capture. Together, these contributions should help evaluate the degree to which attentional capture represents a unitary construct that reflects fundamental theoretical principles and mechanisms of the mind.
