TY - JOUR PY - 2010// TI - Task-dependent representation of moving objects within working memory in obstacle avoidance JO - Strabismus A1 - Hardiess, Gregor A1 - Mallot, Hanspeter A. SP - 78 EP - 82 VL - 18 IS - 3 N2 - Purpose: The purpose of the study was the quantitative analysis of the working memory representation of dynamic objects related to gaze movement behavior. Methods: Eighteen subjects participated in a virtual street-crossing paradigm. The primary task was collisions avoidance. To investigate the representation format, during a sub-task subjects were asked to reconstruct the traffic scene from memory. Results: The distribution of cars positioned during the sub-task reveals a task-dependent (i.e., collision-relevant) representation of about four cars. In contrast, analysis of gaze behavior did not show a preference for collision-prone cars. Conclusion: Subjects avoided collisions efficiently by applying a gaze strategy adequate to create a representation that fulfills the demands of the task. Collision-prone cars are more likely to be represented in memory, but not more likely to be fixated.
