This chapter gives an overview of recent developments in the behavioural and neural analysis of attention. First, it describes the most important behavioural aspects of selective attention. Two important features are competition and bias. The second half of the chapter discusses the possible neural substrates for visual attention, on the basis of what the chapter calls the integrated competition hypothesis. This hypothesis incorporates some of the principles of visual attention derived from behavioural studies, namely competition and bias. Furthermore, it is suggested that the neural substrate for visual attention is not limited to a particular brain region, but that most, if not all visually responsive regions are involved. Finally, this chapter also reviews neurophysiological data from monkeys and neuropsychological evidence from human patients with restricted lesions that broadly support the hypothesis.

Keywords:   attention, competition, bias, integrated competition hypothesis, neural substrate, visual attention
