This study examines eye movements made by a patient with action disorganization syndrome (ADS) as everyday tasks are performed. Relative to both normal participants and control patients, the ADS patient showed normal time-locking of eye movements to the subsequent use of objects. However,
there were proportionately more unrelated fixations, and more fixations concerned with locating objects irrelevant to the immediate action, compared with control participants. The data suggest a dissociation between normal eye movement patterns for control of visually guided actions such as
reaching and grasping, and abnormal eye movements between object-related fixations. The implications for understanding ADS are discussed.
