Oculomotor Control And Cognitive Processes

This volume contains selected and edited papers from the fifth European Conference on Eye Movements (ECEM 5) held at the University of Pavia, Italy on September 10-13, 1989. The volume is organized in six sections as follows: Neurophysiology of Eye Movements; Control of Eye Movements; Eye-Head Coordination; Eye Movements in Pathology; Eye Movements and Cognitive Processes and Applied Research. The last section also contains some papers derived from the satellite symposium on Visual Processes and Eye Movements in Dyslexia, which was organized by the Roding Remediation Foundation.

This is the first book to deal exclusively with oculomotor performance in a series that, up to this point, has been devoted largely to reviews of research on oculomotor anatomy and physiology. The publication of this volume signifies the recognition of the fact that a genuine understanding of eye movement will not come about through the study of neurons alone. We need to know about the capacity to make different kinds of eye movement, and about how such oculomotor capacity is used to accomplish different sorts of visual and cognitive tasks, i.e. how the eye can move and why it moves in particular ways. Research on respective topics was critically evaluated by the contributing authors, resulting in a controversial and up-to-date appraisal of this subject.

Measurement and analysis of eye movements are two of the most powerful ways to study the workings of the human mind. This Special Issue on eye movements and information processing in reading presents an overview of experimental research based on this methodology. Eye movements provide a unique opportunity to examine principles of human information processing in a well-structured visual environment while people engage in a natural cognitive task. At the same time, oculomotor measures can be used as a tool to develop and test psycholinguistic hypotheses about the processing of written language. The papers in this issue contribute to both aspects, addressing issues that dominate current debates in the field. Seen from the angle of visual information processing, a major theme is the role played by parafoveal information for different types and levels of processing and for oculomotor control in reading. This includes effects of visual and linguistic word properties on the selection of words for fixation and the specification of saccade amplitudes. Clearly the most controversial question in this context concerns the allocation of attention, with positions ranging from a sequentially moving spotlight to a gradient of spatially distributed processing. Related to this is the issue of serial vs. parallel word processing and the fundamental question as to what extent the duration of fixations in reading is related to lexical processing. Taking a psycholinguistic perspective, the topics addressed include several levels of language processing from orthography to pragmatic information in sentence reading. New approaches to the study of morphologically complex words are reported, together with novel work revealing the complex nature of the apparently accessible, but elusive, concept of word frequency. Other papers reflect current theoretical discussions centered on the development of computational models of the reading process and contribute to the empirical base of these discussions. Taken together, this collection of papers, supplemented by an introduction to the field and a commentary on major issues, presents a comprehensive and up-to-date perspective on a research area currently characterised by numerous theoretical and empirical disputes. The papers will be of particular appeal to readers interested in basic and applied psycholinguistics, attention and visual perception, motor control and the modelling of complex cognitive processes.

Whether reading, looking at a picture, or driving, how is it that we know where to look next - how does the human visual system calculate where our gaze should be directed in order to achieve our cognitive aims? This book brings together leading vision scientists studying eye movements across a range of activities, such as reading, driving, computer activities, and chess. It provides groundbreaking new research that will help us understand how it is that we know where to move our eyes, and thereby better understand the cognitive processes underlying these activities.

The thirty-two contributions discuss evidence from psychological experiments with healthy and brain-damaged subjects, functional imaging, electrophysiology, and computational modeling.

Originally published in 1981, this volume represents the edited proceedings of the third symposium on eye movements and behaviour sponsored by the US Army Human Engineering Laboratory. The conference, titled "The Last Whole Earth Eye Movement Conference" was held in Florida in February 1980. As the conference approached, seizure of the American hostages by the Iranian militants, the Russian invasion of Afghanistan, and the uncertain economic outlook around the world made it appear as though the title was a self-fulfilling prophecy. But the meeting proved highly successful and people throughout the world seemed to be adapting to the stresses of international tension, making the possibility of subsequent meetings more likely. The present volume is intended to serve as a complementary text to the earlier texts Eye Movements and Psychological Processes (Monty & Senders, 1976) and Eye Movements and the Higher Psychological Functions (Senders, Fisher & Monty, 1978), rather than a revision and update of them.

The distinguished contributors to this volume have been set the problem of describing how we know where to move our eyes. There is a great deal of current interest in the use of eye movement recordings to investigate various mental processes. The common theme is that variations in eye movements indicate variations in the processing of what is being perceived, whether in reading, driving or scene perception. However, a number of problems of interpretation are now emerging, and this edited volume sets out to address these problems. The book investigates controversies concerning the variations in eye movements associated with reading ability, concerning the extent to which text is used by the guidance mechanism while reading, concerning the relationship between eye movements and the control of other body movements, the relationship between what is inspected and what is perceived, and concerning the role of visual control attention in the acquisition of complex perceptual-motor skills, in addition to the nature of the guidance mechanism itself. The origins of the volume are in discussions held at a meeting of the European Society for Cognitive Psychology (ESCOP) that was held in Wurzburg in September 1996. The discussions concerned the landing effect in reading, an effect, that if substantiated, would provide evidence of the use of parafoveal information in eye guidance, and these discussions were explored in more detail at a small meeting in Chamonix, in February 1997. Many of the contributors to this volume were present at the meeting, but the arguments were not resolved in Chamonix either. Other leaders in the field were invited to contribute to the discussion, and this volume is the product. The argument remains unresolved, but the problem is certainly clearer.

Originally published in 1978, this volume reflects the proceedings of a conference held in February 1977 in California and is a natural successor to the earlier volume Eye Movements and Psychological Processes (Monty & Senders, 1976). The second conference was aimed at providing a greater opportunity for discussing the "higher mental processes" touched on in the first volume. Part 1 is devoted to an intensive review of the underlying processes and psychological functions of eye movements. It includes discussions of the relationships of cortical and subcortical visual areas to eye movements and visual processing associated with them; information about the position of the eye in the head and the perception of visual space; saccades and visual functioning; and masking. In further parts it goes on to look at: methodology and models; cognitive processes; reading processes; looking at static and dynamic display; and finally chapters on problems and applications.
