The influence of enantiomorphic transformation on transsaccadic object integration

Two experiments investigated whether the left-right orientation of an object is retained and integrated across a saccade during object identification. In Experiment 1, participants moved their eyes to the target object and named it as quickly as possible. In Experiment 2, participants looked through an array of 4 target objects in preparation for an immediate recognition test. In both experiments, a peripheral preview of the target object was presented before fixation. The preview stimulus was identical to the target object, the enantiomorph of the target object, or a control stimulus. Naming latencies were faster(Experiment I)and gaze durations were shorter (Experiment 2) when the preview was identical to the target than when it was an enantiomorph of the target, suggesting that left-right orientation was retained and integrated across saccades. The results constrain models of transsaccadic integration and object identification.
