This chapter comments on Anne Treisman's 1988 paper Features and objects: The Fourteenth Bartlett Memorial Lecture, published in the Quarterly Journal of Experimental Psychology. Treisman outlines a model for perceptual processing in object perception and discusses the evidence regarding visual search for features and conjunctions. She also considers modularity in feature analysis and the role of attention in feature integration, with particular emphasis on the association between identification and localization, illusory conjunctions with divided attention, and iconic memory and conjunctions of features. Furthermore, Treisman explores top-down effects in object perception, along with “object files” in perceptual representation. This chapter examines Treisman's feature integration theory of attention as it applies to spatial parallelism, the attentional blink paradigm, top-down effects and automaticity, and detection of features without focused attention.

Keywords:   perceptual processing, Anne Treisman, object perception, visual search, features, conjunctions, feature analysis, divided attention, feature integration theory, focused attention
