Abstract

This chapter uses two examples—perceptual grouping and visual attention—to highlight the implications of comparative research for the vision sciences. In perceptual grouping, results from nonhuman animals suggest that vision scientists look beyond the perceptual cues for grouping and consider an organism's goals, its typical behavior, and its environment. In attentional control, a consideration of how a nonverbal, nonhuman animal might control attention has led to a novel application of learning mechanisms to attentional control. The chapters in this book represent more than merely looking at the human vision sciences literature for a paradigm that can be applied to pigeons, rats, or monkeys. The pigeons, rats, and monkeys can provide fresh insights and important new directions for thinking about the origins of visual behavior.
