Attention
Attention is involved in the selective directedness of our mental lives. The nature of this selectivity is one of the principal points of disagreement between the existing theories of attention. Some of the most influential of those theories treat the selectivity of attention as resulting from limitations in the brain’s capacity to process the complex properties of multiple perceivable stimuli. Others take that selectivity to be the result of limitations in the thinking subject’s capacity to consciously entertain multiple trains of thought. A third group attempt to account for attention’s selectivity in ways that need not make any reference to limitations of capacity. These latter theories relate the selectivity of attention to the selectivity required to maintain a single coherent course of action, to the weighting of sensory information in accordance with its expected precision, or to competition between mutually inhibitory streams of processing.
Instances of attention differ along several dimensions. In some of its instances attention is a perceptual phenomenon; in some it is a phenomenon related to action; and in others it is a purely intellectual matter of giving thought to some question. In some instances the selectivity of attention is voluntary. In others it is driven, independently of the subject’s volition, by the high salience of attention-grabbing items in the perceptual field. The difficulty of giving a unified theory of attention that applies to all of these instances makes attention a topic of philosophical interest in its own right.
Attention is also a topic of philosophical interest because of its apparent relations to a number of other philosophically puzzling phenomena. There are empirical and theoretical considerations suggesting that attention is closely related to consciousness, and there are controversies over whether this relationship is one of necessity, or sufficiency (or both or neither). There are also controversies—thought to be important to the viability of representationism about consciousness—over the ways in which the phenomenal character of a conscious experience can be modulated by attention. Different considerations link attention to demonstrative reference, to the experience of emotion, to the development of an understanding of other minds, and to the exercise of the will. Some work in the tradition of virtue ethics takes attention to be morally important, since there are at least some virtues that require one to attend appropriately. Attention has also been given a prominent role in some theories about the epistemic significance of emotional and perceptual experiences, and in some discussions of the epistemic peculiarities of self-attributed mental states.
The controversies concerning attention’s relations to these other phenomena often include debates about the philosophical significance of theories that have been developed through the empirical study of attention at the neuropsychological and cognitive levels. Attention’s cultural and economic aspects have also come to be a point of philosophical interest, with some theorists suggesting that the social and political significance of new media is primarily a consequence of the novel ways in which those media engage and compete for the attention that we individually and collectively pay.
