Available in PDF, EPUB and Kindle. Book excerpt: The goal of this book is to put together some of the main interdisciplinary aspects that play a role in visual attention and cognition. The book is aimed at researchers and students with interdisciplinary interest. In the first chapter a general discussion of the influential scanpath theory and its implications for human and robot vision is presented. Subsequently, four characteristic aspects of the general theme are dealt with in topical chapters, each of which presents some of the different viewpoints of the various disciplines involved. They cover neuropsychology, clinical neuroscience, modeling, and applications. Each of the chapters opens with a synopsis tying together the individual contributions.

Book excerpt: Attention is essential to everyday life: without some selective function to guide and limit the processing of incoming information, our visual system would be overwhelmed. A description of the spatiotemporal dynamics of attention is critical to our understanding of this basic human cognitive function and is the primary goal of this dissertation. In particular, the research reported here is aimed at examining two aspects of the spatiotemporal dynamics of attention: a) the rate at which the focus of attention is shrunk and expanded along with the factors that influence this rate, and b) the factors governing whether attention is deployed as either a unitary or a divided focus. The present research examines the spatiotemporal dynamics of focal attention by monitoring the pattern of accuracy that occurs when participants attempt to identify two targets embedded in simultaneously presented streams of items. By asking participants to monitor these streams simultaneously, with the spatial and temporal positions of the two targets in the streams being varied incrementally, it is possible to index the extent of focal attention in both space and time. Chapter 2 develops this behavioural procedure and assesses the rate at which the focus of attention is contracted. A qualitative model is put forward and tested. Chapter 3 examines factors that modulate the temporal course of attentional narrowing in young adults who presumably can exercise efficient control of attentional processes. In contrast, Chapter 4 examines the effect of reduced attentional control by examining the same process in older adults. The second goal of this thesis was to examine whether focal attention is deployed as a unitary or a divided focus. These two perspectives are generally viewed as mutually exclusive. The alternative hypothesis pursued in Chapter 5 is that focal attention can be deployed as either a single, unitary focus or divided into multiple foci, depending on the observers mental set and on the.

Download or read book The Spatiotemporal Dynamics of Visual Attention During Real world Event Perception written by Ryan Ringer and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Everyday event perception requires us to perceive a nearly constant stream of dynamic information. Although we perceive these events as being continuous, there is ample evidence that we "chunk" our experiences into manageable bits (Zacks & Swallow, 2007). These chunks can occur at fine and coarse grains, with fine event segments being nested within coarse-grained segments. Individual differences in boundary detection are important predictors for subsequent memory encoding and retrieval and are relevant to both normative and pathological spectra of cognition. However, the nature of attention in relation to event structure is not yet well understood. Attention is the process which suppresses irrelevant information while facilitating the extraction of relevant information. Though attentional changes are known to occur around event boundaries, it is still not well understood when and where these changes occur. A newly developed method for measuring attention, the Gaze-Contingent Useful Field of View Task (GC-UFOV; Gaspar et al., 2016; Ringer, Throneburg, Johnson, Kramer, & Loschky, 2016; Ward et al., 2018) provides a means of measuring attention across the visual field (a) in simulated real-world environments and (b) independent of eccentricity-dependent visual constraints. To measure attention, participants performed the GC-UFOV task while watching pre-segmented videos of everyday activities (Eisenberg & Zacks, 2016; Sargent et al., 2013). Attention was probed from 4 seconds prior to 6 seconds after coarse, fine, and non-event boundaries. Afterward, participants' memories for objects and event order were tested, followed by event segmentation. Attention was predicted to either become impaired (attentional impairment hypothesis), or it was predicted to be broadly distributed at event boundaries and narrowed at event middles (the ambient-to-focal shift hypothesis). The results showed marginal evidence for both attentional impairment and ambient-to-focal shift hypotheses, however model fitness was equal for both models. The results of this study were then used to develop a proposed program of research to further explore the nature of attention during event perception, as well as the ability of these two hypotheses to explain the relationship between attention and memory during real-world event perception.

Download or read book Visual Attention in Children written by Kenneth Lane and published by Taylor & Francis. This book was released on 2024-06-01 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: In typical child development, attention controls many aspects of learning, including memory, motor control, and problem solving. Attention organizes the constant influx of information that needs to be absorbed by children. Inside Visual Attention in Children: Theories and Activities, Dr. Kenneth A. Lane describes the positive aspects of attention that are needed for children to be successful in the classroom, such as concentration and vigilance, as opposed to negative aspects that can lead to failure, such as distractibility and confusion. This book is divided into two parts. The first eight chapters of the book explain attention and its relationship to vision and visual stimuli. The core topics discussed here include Autism, ADHD, Dyslexia, Executive Function, and Memory. The second half outlines a Vision Therapy program and consists of activities for improving visual attention in children. Over 100 activities are explained and illustrated. Visual Attention in Children: Theories and Activities is anchored on current theories in five areas of attention that shape child development. Theories Described Include: Focused Attention – The ability to respond discreetly to visual, auditory, and tactile stimuli Selective Attention – The ability to maintain behavioral or cognitive abilities in the face of distracting or competing stimuli Shifting Attention – The ability to rapidly shift attention from one object to another Sustained Attention – The ability to maintain a consistent behavioral response during a continuous or repetitive activity Divided Attention –The ability to engage in more than one attention-focused task at one time Visual Attention in Children: Theories and Activities is the perfect tool for occupational therapy students and clinicians as well as other professionals specializing in child development and learning who are looking to enhance their understanding of this topic and who need unique ideas and activities to add to their visual therapy training programs.

Available in PDF, EPUB and Kindle. Book excerpt: To generate coherent behavior, the brain needs to attend selectively to the many objects that are present in the environment, but this poses several questions. How does the brain know which objects 'belong together'? How does the information from different senses get combined? How does this help to plan and carry out actions? The subject of attentional mechanisms has a long history in cognitive psychology, as it is the key to making sense of the visual world. However, new developments in cognitive neuroscience, and greater understanding of how attention and action are integrated, have transformed the field. This book is the first to bring together leading researchers to discuss the convergence of experimental findings in the following areas: visual selective attention, attention and perceptual integration, spatial representation and attention, visual attention and action, and control of attention. Attention, Space, and Action provides a unique combination of perspectives that will appeal to students and researchers from psychology, neuropsychology, neurophysiology, and neuroanatomy.

Download or read book Motion Integration in Visual Attention Models for Predicting Simple Dynamic Scenes written by and published by . This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual attention models mimic the ability of a visual system, to detect potentially relevant parts of a scene. This process of attentional selection is a prerequisite for higher level tasks such as object recognition. Given the high relevance of temporal aspects in human visual attention, dynamic information as well as static information must be considered in computer models of visual attention. While some models have been proposed for extending to motion the classical static model, a comparison of the performances of models integrating motion in different manners is still not available. In this article, we present a comparative study of various visual attention models combining both static and dynamic features. The considered models are compared by measuring their respective performance with respect to the eye movement patterns of human subjects. Simple synthetic video sequences, containing static and moving objects, are used to assess the model suitability. Qualitative and quantitative results provide a ranking of the different models.

Available in PDF, EPUB and Kindle. Book excerpt: The human brain deals, at every instant, with a huge amount of visual stimuli. Besides that, the problem of treating all this information becomes even more complex if we consider that each component of a given stimuli needs to be compared to a set of known signals stored in memory. In Chapter One a numerical solution of Hodgkin Huxley equations is presented to describe the behavior of a neuron and the solution is illustrated by a graphical chart interface to finely tune the behavior of the neuron visually programmed in Java. Chapter Two explores the connection between visual attention algorithms and the recognition of objects by computers in digital images. Chapter Three reviews research and provides original data asserting that bias in legal judgment persists despite the inclusion of visual evidence partly because decision-makers perceptions of visual evidence may be swayed by subjective factors. The preference for a product is usually influenced by the visual appearance of the product image. Chapter Four proposes a new content-based approach, denominated CBAS, that combines textual attributes, visual features and visual attention to compose the products profile. Chapter Five uses electroencephalography (EEG) to investigate the brain activations of visual attention in production designers and analyse the differences between higher creativity (HC) and lower creativity (LC) designers.

Download or read book Visual Spatial Attention written by Lana Haynes and published by Nova Science Publishers. This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many events in our daily lives require that we allocate attentional resources towards relevant information in the environment. However, we are constantly presented with more information than we can possibly attend to at any given moment. Visual spatial attention is the prioritisation of visual processing to a particular spatial region in ones environment, and is therefore an important component of attention (more broadly construed) and information-processing. Once a region of space has been selected by visual spatial attention, the objects and features within that region can be processed. In this book, Chapter One examines visual spatial attention and its functional role in a variety of cognitive tasks. Chapter Two reviews the different ways in which the various mechanisms of selective attention have been cortically and otherwise classified into low and high levels of processing and to disentangle some of the confusion that may have arisen as a result of inconsistent usage of terminology and concepts in the field. The last chapter discusses studies which use computer simulations to estimate the effect of noise correlation upon the performance benefit gained from cues.
