peripheral cue used by Egly, Driver, and Rafal () included features of both exogenous and endogenous cues: On the one hand, like an exogenous cue, it was a peripherally presented luminance change (abrupt onset and offset), which should have automatically and directly captured attention. On the other hand, like an endog-. Duncan, ; Egly, Driver, Rafal, ; Gibson Egeth, ; Kanwisher Driver, ) and with brain- damaged patients (Behrmann Moscovitch, ; Car- amazza Hillis, ; Driver Halligan, ) suggests that attention can operate on object- as well as on location- based representations and that accessing one representation. We adapted the classical double-rectangle cueing paradigm of Egly, Driver, and Rafal (), and measured both the first saccade latency and the keypress reaction time (RT) to a target that.

Egly, Driver, and Rafal () had participants look at displays that featured two rectangles (A and B) standing on end, equidistant from a central fixation point. On a given trial, a target stimulus was presented at the top or bottom of one of the rectangles. than whentheyform a nonword. Experiment 2A presentedcharacters either aloneor withinrectangles (Egly, Driver, Rafal, ) and the characters in a rectangle formed either a word or a nonword. Experiment 2B differed from Experiment 2A in that the two characters forming a word were in different rectangles.

Egly et aI.() had their subjects detect a luminance change in one ofthe four corners oftwo outline rectan­ gles. One corner was precued. On valid-cuetrials, the.
