This book presents a comprehensive theoretical framework that explains both human consciousness and meanings through the working of attention. By arguing for a first-person approach to consciousness, this book offers a critical overview of the major theories and empirical findings on consciousness and attention, and exemplifies how one of the most difficult and fundamental conscious experiences to account for, that is, time, can be analyzed by adopting the kind of semantics developed within the presented theoretical framework: Attentional Semantics.

In this article, I argue that consciousness is a unique way of processing information, in that: it produces information, rather than purely transmitting it; the information it produces is meaningful for us; the meaning it has is always individuated. This uniqueness allows us to process information on the basis of our personal needs and ever-changing interactions with the environment, and consequently to act autonomously. Three main basic cognitive processes contribute to realize this unique way of information processing: the self, attention (...) and working memory. The self, which is primarily expressed via the central and peripheral nervous systems, maps our body, the environment, and our relations with the environment. It is the primary means by which the complexity inherent to our composite structure is reduced into the “single voice” of a unique individual. It provides a reference system that (albeit evolving) is sufficiently stable to define the variations that will be used as the raw material for the construction of conscious information. Attention allows for the selection of those variations in the state of the self that are most relevant in the given situation. Attention originates and is deployed from a single locus inside our body, which represents the center of the self, around which all our conscious experiences are organized. Whatever is focused by attention appears in our consciousness as possessing a spatial quality defined by this center and the direction toward which attention is focused. In addition, attention determines two other features of conscious experience: periodicity and phenomenal quality. Self and attention are necessary but not sufficient for conscious information to be produced. Complex forms of conscious experiences, such as the various modes of givenness of conscious experience and the stream of consciousness, need a working memory mechanism to assemble the basic pieces of information selected by attention.

The primary determinant of the self (S) is the conscious experience (CE) we have of it. Therefore, it does not come as a surprise that empirical research on S mainly resorts to the CE (or lack of CE) that subjects have of their S. What comes as a surprise is that empirical research on S does not tackle the problem of how CE contributes to building S. Empirical research investigates how S either biases the cognitive processing of stimuli or is (...) altered through a wide range of means (meditation, hypnosis, etc.). In either case, even for different reasons, considerations of how CE contributes to building S are left unspecified in empirical research. This article analyzes these reasons and proposes a theoretical model of how CE contributes to building S. According to the proposed model, the phenomenal aspect of consciousness is produced by the modulation—engendered by attentional activity—of the energy level of the neural substrate (that is, the organ of attention) that underpins attentional activity. The phenomenal aspect of consciousness supplies the agent with a sense of S and informs the agent on how its S is affected by the agent’s own operations. The phenomenal aspect of consciousness performs its functions through its five main dimensions: qualitative, quantitative, hedonic, temporal, and spatial. Each dimension of the phenomenal aspect of consciousness can be explained by a specific aspect of the modulation of the energy level of the organ of attention. Among other advantages, the model explains the various forms of S as outcomes resulting from the operations of a single mechanism and provides a unifying framework for empirical research on the neural underpinnings of S.

Among the cognitive processes involved in the construction of any kind of meaning, attention is fundamental in determining why, how and what we mean. Attention plays a primary role in the process of learning the meanings of words and more generally of acquiring knowledge; signification, discourse and persuasion; perceiving, representing and (re)framing reality; shaping the attitudes of the audience; conveying values and ideologies. Conversely, the meanings of words and more generally, of signs, convey the condensed instructions for the attentional operations (...) one has to perform in order to consciously experience what is expressed through and by them. Language, by addressing and guiding attention in specific ways, helps to select, amplify and support certain semantic components and concepts, and construct and communicate knowledge and values. This book is the first to present a comprehensive overview of the extant research on the relationships between attention and meaning. The contributions collected here offer an overview of the most prominent theories and models developed so far that aim to explain how attention determines meaning construction. This book will be of interest to students, researchers and teachers in the realm of linguistics, semantics, discourse studies, semiotics, psycholinguistics, computational linguistics, linguistic development, cognitive architectures of language, neuropsychology of linguistic function and social psychology.
