Book Description
In the late-1980s, visual cognition was a small subfield of cognitive psychology, and the standard texts mainly discussed just iconic memory in their sections on visual cognition. In the subsequent two decades, and especially very recently, many remarkable new aspects of the processing of brief visual stimuli have been discovered -- change blindness, repetition blindness, the attentional blink, newly-discovered properties of visual short-term memory and of the face recognition system, the influence of reentrant processing on visual perception, and the surprisingly intimate relationships between eyeblinks and visual cognition. This volume provides up-to-date tutorial reviews of these many new developments in the study of visual cognition written by the leaders in the discipline, providing an incisive and comprehensive survey of research in this dynamic field.

Book Description
Perceptual experience emerges from neural computations. "Unconscious Memory Representations in Perception "focuses on the role of implicit (non-conscious) memories in processing sensory information. Making sense of the wealth of information arriving at our senses requires implicit memories, which represent environmental regularities, contingencies of the sensory input, as well as general contextual knowledge. Recent findings and theories in cognitive and computational neuroscience provided new insights into the structure and contents of implicit memory representations. The chapters of this book examine implicit memories both in relatively simple situations, such as perceiving auditory and visual objects, as well as in high?level cognitive functions, such as speech and music perception and aesthetic experience. By nature, implicit memories cannot be directly studied with behavioral methods. Therefore, a large part of the evidence reviewed was obtained in neuroscientific studies. Readers with limited experience in neuroscience will find information about the most commonly used techniques in the appendix of this volume. (Series B)

Book Description
The neural mechanisms underlying visual perception and attention continue to elude researchers despite decades of research. Developing novel methodology and improved analytical techniques may provide key insights into these processes that traditional approaches have been unable to reveal. In this dissertation, we pursue this idea in a series of studies whose overall aim is to better understand visual perception, attention, and their underlying neural mechanisms. First, we demonstrate how the novel adaptation of visual working memory probabilistic models can turn simple performance measures into metrics that quantify the quality of participants' internal perceptual representations. When paired with EEG analysis, we find evidence that perceptual representations will vary only within a fixed range of values, but where in that range its precision falls changes from trial-to-trial as a function of post-stimulus neural activity. Next, we extend this approach to test the effects of covert attention modulation while simultaneously questioning previous assumptions about the role of periodic oscillatory activity, particularly in the alpha (8-14 Hz) frequency, during the cued version of the orientation perception task. From this novel combination, we find evidence that the conflicting reports on the role of alpha oscillations in visual perception and attention are, at least partially, due to measures being confounded by the overlapping and task-related 1/f aperiodic activity. Finally, we used multivariate pattern analysis (MVPA) to address a long-standing question regarding how alpha-related brain activity prior to the presentation of a visual stimulus corresponds to attention, perception, and subsequent task performance. Our results suggest that it is the complex spatiotemporal dynamics of alpha amplitude that best represents what makes trials with covert spatial attention distinguishable from trials without. However, we found little evidence that those same spatiotemporal patterns of activity are predictive of subsequent behavioral responses. Overall, this series of studies demonstrate the value of using novel techniques that can take full advantage of the inherent multidimensionality of EEG data as well as highlights the opportunities these methods present for future research.

The book covers a number of broad themes relevant to visual attention, ranging from computer vision to psychology and physiology of vision. The main theme of the book is the attention processes of vision systems and it aims to point out the analogies and the divergences of biological vision with the frameworks introduced by computer scientists in artificial vision.

Book Description
Much of our behavior is guided by our understanding of events. We perceive events when we observe the world unfolding around us, participate in events when we act on the world, simulate events that we hear or read about, and use our knowledge of events to solve problems. In this book, Gabriel A. Radvansky and Jeffrey M. Zacks provide the first integrated framework for event cognition and attempt to synthesize the available psychological and neuroscience data surrounding it. This synthesis leads to new proposals about several traditional areas in psychology and neuroscience including perception, attention, language understanding, memory, and problem solving. Radvansky and Zacks have written this book with a diverse readership in mind. It is intended for a range of researchers working within cognitive science including psychology, neuroscience, computer science, philosophy, anthropology, and education. Readers curious about events more generally such as those working in literature, film theory, and history will also find it of interest.
