  • Contraction of perceived size and perceived depth in mirrors Atsuki Higashiyama Koichi Shimono Wataru Zaitsu Psicología We investigated how size and depth are perceived in a plane or convexmirror. In Experiment 1, using a plane or convex mirror, 20 observersviewed a separation between two objects that were presented at a constantdistance and reproduced it by a separation between other two objects in anatural viewing situation. The mean matches generally approximated thereal size of the standard and did not equal either virtual size or visual angle ofthe standard. In addition, the mean matches obtained with convex mirrorswere reduced by about 7% in comparison with those obtained with the planemirror. In Experiment 2, we examined whether the perceived depth in aconvex mirror is comparable to that in a plane mirror. We presentedisosceles triangles on a table and required 12 observers to observe them witha plane or convex mirror. With the method of limits, we determined thetriangle that was perceived as an equilateral triangle. When the apexes ofisosceles triangles were directed to the observer or to depth, the ratio ofheight to base was larger in convex mirrors than in the plane mirror,whereas when the apexes were directed to left or to right, the ratio of heightto base was smaller in the convex mirrors than in the plane mirror. Thecontraction of perceived depth amounted to about 6% in convex mirrors.The results of both experiments suggest that although separation and depthin convex mirrors appear to reduce, there is a strong tendency that visualsystem recovers the optical distortions by convex mirrors. 2005 artículo científico 0211-2159 https://www.redalyc.org/articulo.oa?id=16926106 en http://www.redalyc.org/revista.oa?id=169 Psicológica application/pdf Universitat de València Psicológica (España) Num.1 Vol.26
