PLoS ONE 12(12):Įditor: Jorge Marin Mpodozis, Universidad de Chile, CHILE The present results have implications as to how populations differ in their efficiency of using stereoscopic cues for disambiguating complex dynamic scenes.Ĭitation: Plourde M, Corbeil M-E, Faubert J (2017) Effect of age and stereopsis on a multiple-object tracking task. These results show that stereopsis helps children and adults accomplish a MOT task, but has no impact on older adults’ performances. The performance difference between the stereoscopic and non-stereoscopic conditions was significant and similar for the adults and the children but was non significant for the older observers.
The adult group obtained the better scores, followed by the children and the older adult group. A total of 60 observers consisting of three groups of 20 subjects (7–12 years old, 18–40 years old and 65 years and older) completed the task in both conditions (with and without stereoscopic effects). In the present study we evaluated the impact of stereopsis on a MOT task as a function of age. One task that shares characteristics with the requirements for processing dynamic crowds is the multiple object-tracking task (MOT). It is still relatively unknown how stereopsis is used in more complex/ecological contexts such as when walking about in crowds where objects are in motion and occlusions occur. 3D vision develops during childhood and tends to diminish after 65 years of age.
