ABSTRACT
Object attention has been proposed as one of the fundamental attentional modes of processing visual environments. This chapter focuses on experiments that measure the accuracy of perceiving and reporting basic visual features. The impact of object attention on visual perceptual performance depends on many factors, including the nature or dimensions of the judgments, the classification frames for those judgments, the precision of the judgment, the degree of practice, and perhaps on individual variation or capacity to manage multiple judgment frames. It shows improved templates and consequent improved filtering of external noise is the primary mechanism in object attention. There are few studies whether behavioral or physiological that has set out to measure the independent or interactive effects of spatial, feature, and object attention. Over the course of multiple experimental investigations of spatial attention and object attention, the chapter observes that there can be quite wide variations over individuals in the magnitude of the expressions of object attention.
