The feature integration theory of object perception (Treisman & Gelade, 1980) suggests that the perception of multidimensional stimuli requires that attention be serially directed to the items in a visual display in order to correctly conjoin features into objects, while the perception of features does not require serial attention. Under conditions in which the serial focusing of attention is disrupted by reducing display duration, available information about conjunctions of two features should not exceed the independent information available about the constituent features. Three experiments using a partial report paradigm employing a location cue were conducted in order to test this prediction. Subjects viewed colored letter displays that varied in cue-display stimulus onset asynchrony. The dependent measure was accuracy of response. Results suggest that a small amount of information from a separate representation of conjunctions of features may be accessible. / Arts, Faculty of / Psychology, Department of / Graduate
