We make 3-5 eye movements per second, and these movements are crucial in helping us deal with the vast amounts of information we encounter in our everyday lives. In recent years, thanks to the development of eye tracking technology, there has been a growing interest in monitoring and measuring these movements, with a view to understanding how we attend to and process the visual information we encounter Eye tracking as a research tool is now more accessible than ever, and is growing in popularity amongst researchers from a whole host of different disciplines. Usability analysts, sports scientists, cognitive psychologists, reading researchers, psycholinguists, neurophysiologists, electrical engineers, and others, all have a vested interest in eye tracking for different reasons. The ability to record eye-movements has helped advance our science and led to technological innovations. However, the growth of eye tracking in recent years has also presented a variety of challenges - in particular the issue of how to design an eye-tracking experiment, and how to analyse the data. This book is a much needed comprehensive handbook of eye tracking methodology. It describes how to evaluate and acquire an eye-tracker, how to plan and design an eye tracking study, and how to record and analyse eye-movement data. Besides technical details and theory, the heart of this book revolves around practicality - how raw data samples are converted into fixations and saccades using event detection algorithms, how the different representations of eye movement data are calculated using AOIs, heat maps and scanpaths, and how all the measures of eye movements relate to these processes. Part I presents the technology and skills needed to perform high-quality research with eye-trackers. Part II covers the predominant methods applied to the data which eye-trackers record. These include the parsing of raw sample data into oculomotor events, and how to calculate other representations of eye movements such as heat maps and transition matrices. Part III gives a comprehensive outline of the measures which can be calculated using the events and representations described in Part II. This is a taxonomy of the measures available to eye-tracking researchers, sorted by type of movement of the eyes and type of analysis. For anyone in the sciences considering conducting research involving eye-tracking, this book will be an essential reference work.

The book Infinity in Language is a research monograph on the problem of the sublime in language. The authors use methods from cognitive semantics and poetics in order to thoroughly describe how the sublime is used in language. It is a unique attempt to account for one of the most fascinating problems of the human mind: the concept of infinity, and how the experience of infinity and enthusiasm is expressed in language. The book includes new findings in cognitive semantics relating to rhetorical figures such as hyperbole, gradation and accumulation. Cognitive semantics has focused so far on metaphor. This book fills the gap and gives an account of other rhetorical figures. It contains also a historical review of major theories of the sublime by Pseudo-Longinos, Boileau, Burke, Kant, Schiller, Hegel, Schopenhauer, Nietzsche and others, i.e. it spans a period from the first century AD till twentieth century. The authors answer the question how is it possible to present the unpresentable. It is an attempt to outline and develop a model of the rhetoric of the sublime. The model consists of three elements: antimimetic evocation of the unimaginable, a mimesis of emotions and figures of the discourse of the sublime. The books argues in favour of non-cartesian semantics which takes into account not only reason but also emotions, especially very intensive ones. However, the authors also express reservations regarding omnipresent rhetoric of the sublime. They follow those thinkers in the human history who argued against fanaticism and in favour of tolerance and empathy. The book is an original result of an interdisciplinary and international collaboration, lasting many years, between a cognitive scientist and a linguist and literary scholar.
