Continuous visual cues trigger automatic spatial target updating in dynamic scenes
چکیده انگلیسی

Dynamic tasks often require fast adaptations to new viewpoints. It has been shown that automatic spatial updating is triggered by proprioceptive motion cues. Here, we demonstrate that purely visual cues are sufficient to trigger automatic updating. In five experiments, we examined spatial updating in a dynamic attention task in which participants had to track three objects across scene rotations that occurred while the objects were temporarily invisible. The objects moved on a floor plane acting as a reference frame and unpredictably either were relocated when reference frame rotations occurred or remained in place. Although participants were aware of this dissociation they were unable to ignore continuous visual cues about scene rotations (Experiments 1a and 1b). This even held when common rotations of floor plane and objects were less likely than a dissociated rotation (Experiments 2a and 2b). However, identifying only the spatial reference direction was not sufficient to trigger updating (Experiment 3). Thus we conclude that automatic spatial target updating occurs with pure visual information.


► We demonstrate that pure visual cues can trigger automatic spatial updating.
► Participants tracked several objects among distractors.
► During invisibility intervals, object positions were dissociated from the floor plane.
► Participants could not ignore visual rotation cues of the floor plane.
► Updating effectiveness was independent of the validity of floor plane rotations.
