This chapter presents a theory that applies the computational principles of TVA to attentional effects at the single-cell level: a neural theory of visual attention (NTVA). The basic idea of NTVA is that the two selection mechanisms of TVA – pigeonholing and filtering – are directly reflected in the activity of individual neurons: pigeonholing changes the activity level of individual neurons that signal particular categorizations, whereas filtering changes the number of neurons that respond to particular objects. In combination these two mechanisms control the total activity level in each population of neurons that signals a particular categorization of an object. In competition with other cell populations in the visual system, which support other categorizations, each population's level of activity determines whether the categorization it supports will enter visual short-term memory (VSTM).

Keywords:   visual short-term memory, neural networks, visual processing, attentional effects, single cell, pigeonholing, filtering
