A visual system cannot process everything with full fidelity, nor, in a given moment, perform all possible visual tasks. Rather, it must lose some information, and prioritize some tasks over others. The human visual system has developed a number of strategies for dealing with its limited capacity. This paper reviews recent evidence for one strategy: encoding the visual input in terms of a rich set of local image statistics, where the local regions grow — and the representation becomes less precise — with distance from fixation. The explanatory power of this proposed encoding scheme has implications for another proposed strategy for dealing with limited capacity: that of selective attention, which gates visual processing so that the visual system momentarily processes some objects, features, or locations at the expense of others. A lossy peripheral encoding offers an alternative explanation for a number of phenomena used to study selective attention. Based on lessons learned from studying peripheral vision, this paper proposes a different characterization of capacity limits as limits on decision complexity. A general-purpose decision process may deal with such limits by "cutting corners" when the task becomes too complicated.
