Book Description
The aim of this Frontiers Research Topic is to review and further explore the topic of unconscious processing in executive control. Executive control refers to the ability of the human brain – mostly associated with prefrontal cortex activity - to regulate the processing involved in the execution of novel or complex goal-directed tasks. Previous studies or models of human cognition have assumed that executive control necessarily requires conscious processing of information. This perspective is in line with common sense and personal introspection, which suggest that our choices are intentional and based on conscious stimuli. Nevertheless, in the last few years several behavioural and cognitive neuroscience studies have put under scrutiny this assumption. Cumulating evidence is now showing that prefrontal executive control can involve or be triggered by unconscious processing of information, with consequent effects on observed behaviours. One of the main methods adopted to study such unconscious mechanisms is masked priming, consisting in presenting visually masked stimuli, which nonetheless are shown to affect goal-directed behaviour or influence constructs linked to executive control and prefrontal cortex activity (e.g., task-set representation, response inhibition, conflict monitoring, error detection, reward processing, emotion regulation and task switching). This area of research is relatively young, and - while scientific evidence is emerging - no general consensus has been reached yet on how to interpret these early findings: some researchers accept that executive control can involve unconscious processing, others momentarily put aside - in first approximation - this issue, others criticize this possibility on theoretical grounds (e.g., pointing to the need of better definitions of terms such as control, conflict and consciousness) or based on experimental findings. At this stage, it appears necessary that researchers in the field make a collective effort to deepen the understanding of the unconscious mechanisms involved in executive control. This Research Topic will focus on neuroscience, but it will welcome contributions on purely behavioural and psychophysiological studies, patient reports, computational investigations, as well as philosophical and historical analyses of the relationship between executive control and consciousness. In particular, we encourage experts in this field to submit contributions in the form of: a) reviews, opinions and discussions on existing literature concerning unconscious processing of information in executive control; b) original research articles (both behavioural-only and neuroimaging studies) on unconscious processing of information in executive control; c) discussions and opinions on new methodologies to investigate this issue (e.g., other than masked priming, which has been the technique of choice in most of the existing studies).

Book Description
This eBook is a volume based on the “Eye Movements and Visual Cognition” Special Issue published in the journal Vision by MDPI and edited by Raymond Klein and Simon Liversedge. The eBook comprises 19 high-quality chapters that are original and topical works by leading academic figures in the field of human vision and visual cognition. In putting together the book, we aimed to provide an informative body of work to stimulate and foster useful intellectual exchange between individuals working on basic theoretical issues as well as on more applied aspects of vision and cognitive science. From the outset, we sought papers that provide concise and astute reviews of topics within this broad field. The present volume includes reviews that are narrative (critiquing and summarizing research on a topic), tutorial (with a focus on methods and findings), empirical (e.g., meta-analytic), and theoretically synthetic. The eBook also features chapters with new empirical content that resolves an undecided issue stemming from an evaluation of the literature. Finally, where possible, we also selected papers that bridge theoretical and applied issues and provide insight into behavior and its neural substrate. All chapters were subject to peer review and went through several rounds of revision prior to acceptance.

Book Description
To what level are invisible stimuli processed by the brain in the absence of conscious awareness? It is widely accepted that simple visual properties of invisible stimuli are processed; however, the existence of higher-level unconscious processing (e.g., involving semantic or executive functions) remains a matter of debate. Several methodological factors may underlie the discrepancies found in the literature, such as different levels of conservativeness in the definition of “unconscious” or different dependent measures of unconscious processing. In this research topic, we are particularly interested in yet another factor: inherent differences in the amount of information let through by different suppression techniques. In the same conditions of well-controlled, conservatively established invisibility, can we show that some of the techniques in the “psychophysical magic” arsenal (e.g., masking, but also visual crowding, attentional blink, etc.) reliably lead to higher-level unconscious processing than others (e.g., interocular suppression)? Some authors have started investigating this question, using multiple techniques in similar settings . We argue that this approach should be extended and refined. Indeed, in order to delineate the frontiers of the unconscious mind using a contrastive method, one has to disentangle the limits attributable to unawareness itself, and those attributable to the technique inducing unawareness. The scope of this research topic is to provide a platform for scientists to contribute insights and further experiments addressing this fundamental question.

Book Description
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.

Book Description
This volume brings together the primary challenges for 21st century cognitive sciences and cultural neuroscience in responding to the nature of human identity, self, and evolution of life itself. Through chapters devoted to intricate but focused models, empirical findings, theories, and experiential data, the contributors reflect upon the most exciting possibilities, and debate upon the fundamental aspects of consciousness and self in the context of cultural, philosophical, and multidisciplinary divergences and convergences. Such an understanding and the ensuing insights lie in the cusp of philosophy, neurosciences, psychiatry, and medical humanities. In this volume, the editors and contributors explore the foundations of human thinking and being and discuss both evolutionary/cultural embeddedness, and the self-orientation, of consciousness, keeping in mind questions that bring in the interdisciplinary complexity of issues such as the emergence of consciousness, relation between healing and agency, models of altered self, how cognition impacts the social self, experiential primacy as the hallmark of consciousness, and alternate epistemologies to understand these interdisciplinary puzzles.

Book Description
This book applies a psycholinguistic perspective to instructed second language acquisition, seeking to bridge the gap between second language acquisition research and language teaching practices. It challenges the traditional divide between conscious and unconscious processes, or explicit and implicit learning, and re-envisions this as a continuum of the varying levels of consciousness which can be applied by learners to different language behaviors in the second language classroom. It applies this model to learner development and the classroom context, discussing pedagogical applications for instructors at all levels. This book will be of interest to researchers and graduate students in second language acquisition, psycholinguistics and language pedagogy. The accessible discussion of research findings, pedagogical approaches and classroom tasks and activities make this book particularly relevant for language teachers, providing the tools needed to apply second language acquisition research in their classroom.

Book Description
This book explores the basic concept of agency and develops it further in psychology using it to better understand and explain psychological processes and behavior. More importantly, this book seeks to put an emphasis on the role of agency in four distinct settings: history of psychology, neuroscience, psychology of religion, and sociocultural theories of co-agency. In Volume 12 of the Annals of Theoretical Psychology the contributors explore a number of new ways to look at agency in psychology. This volume seeks to develop a systematic theory of axioms for agency. It describes implications for research and practice that are founded on an understanding of the person as an actor in the world. This book also has implications for research and practice across psychology's sub-fields uniting the discipline through an agentic view of the person

Book Description
Visual control of our actions can be unconscious as well as conscious. For example, when a pedestrian steps onto a street and then suddenly steps back, to avoid being hit by an oncoming car, the pedestrian's visual system has been able to detect the car very rapidly. Since the registration of the approaching car in conscious vision could take a few hundreds of milliseconds - possibly too long to avoid being struck by it, the rapid injury-avoiding action has relied on the oncoming car being detected at unconscious levels in the visual system. So how, and at what level in the visual system is a stimulus processed unconsciously? This book explores unconscious and conscious vision, investigated using psychophysical and brain-recording methods. These methods allow microtemporal analyses of visual processing during the interval, ranging from a few 10s to a few 100s of milliseconds, between a stimulus's impinging on the retinae and its eliciting a behavioral response or a conscious percept. By tying these findings to well-known neuroanatomical and physiological substrates of vision, the book presents and discusses theoretical and empirical approaches to, and findings on, conscious and unconscious vision. In addition to presenting an in-depth, integrative review of recent and ongoing scientific and scholarly research, the book proposes several avenues for directing future research in these areas. It also provides a well articulated theoretical and a detailed empirical base that points to the special importance of the processing of surface properties of visual objects to their conscious vision. Aimed at scientists and scholars in visual cognition, visual neuroscience and, more broadly, cognitive science - including that part of the philosophical community that is currently occupied with the mind-brain problem, the book sheds new light on and advances experimental, philosophical, and scholarly research on visual consciousness.
