There is an overriding orthodoxy amongst philosophers that attention is a ‘unified phenomenon’, subject to explanation by one monistic theory. In this paper, I examine whether this philosophical orthodoxy is reflected in the practice of psychology. I argue that the view of attention that best represents psychological work is a variety of conceptual pluralism. When it comes to the psychology of attention, monism should be rejected and pluralism should be embraced. 1. The Monistic Consensus 2. The Varieties of Pluralism 3.
