- Perception of Acceleration in Motion-In-Depth With Only Monocular and Binocular Information Joan López-Moliner Alejandro Maiche Santiago Estaún Psicología Observers are often required to adjust actions with objects that change theirspeed. However, no evidence for a direct sense of acceleration has beenfound so far. Instead, observers seem to detect changes in velocity within atemporal window when confronted with motion in the frontal plane (2Dmotion). Furthermore, recent studies suggest that motion-in-depth isdetected by tracking changes of position in depth. Therefore, in order tosense acceleration in depth a kind of second-order computation would haveto be carried out by the visual system. In two experiments, we show thatobservers misperceive acceleration of head-on approaches at least within theranges we used [600-800 ms] resulting in an overestimation of arrival time.Regardless of the viewing condition (only monocular or monocular andbinocular), the response pattern conformed to a constant velocity strategy.However, when binocular information was available, overestimation washighly reduced. 2003 artículo científico 0211-2159 https://www.redalyc.org/articulo.oa?id=16924106 en http://www.redalyc.org/revista.oa?id=169 Psicológica application/pdf Universitat de València Psicológica (España) Num.1 Vol.24
