The brain exhibits remarkable facility in exerting attentional control in most circumstances, but it also suffers apparent limitations in others. Our goal is to construct a rational account for why attentional control appears sub-optimal under conditions of conflict, and what it implies about the underlying computational principles. The formal framework we employ is based on Bayesian probability theory, which provides a convenient language for delineating the rationale and dynamics of attentional selection. We illustrate these issues using the Eriksen flanker task, a classical paradigm that explores the effects of competing sensory inputs on response tendencies. We show how two distinctly formulated models, based on compatibility bias and spatial uncertainty principles, can account for the behavioral data. We also suggest novel experiments that may differentiate these models. In addition, we elaborate a simplified model that approximates optimal computation, and may map more directly onto the underlying neural machinery. This approximate model uses conflict monitoring, putatively mediated by the anterior cingulate cortex, as proxy for compatibility representation. We also consider how this conflict information might be disseminated and used to control processing.
