| Abstract(in English) | We measured search time for discrimination to investigate how visual system represents a geometric angle. In these visual searches, many pairs of bounding two lines gave rise to a marked search asymmetry. In particular the search time when 90 degree stimulus was target was slower than that when 90 degree stimuli were distractors. These results indicate that we encode a deviation from 90 degree (right angle) rather than the size of a geometric angle. From this suggestion, we propose a mathematical model of representation of a geometric angle. We showed that an application of this model was depth perception on line drawings. |
