Sažetak
The aim of this study was to determine whether participants are capable of precisely locating the position of the angle vertex after a brief presentation. Our previous experiments, using a two alternative forced choice method, showed a systematic bias in angle vertex perception. When forced to choose the location of a previously presented angle vertex, participants systematically more frequently chose the location which was in actuality located on the inner area of a 90° angle, when compared to an outer area. From those results we hypothesized that angles and perhaps other geometric figures are visually localized based on some inner point rather than the precise vertex position. The current study attempted to replicate these findings using a different method. The participants’ task was to move a plus-shaped mouse pointer to the perceived location of a previously presented target. In Experiment 1 (N = 34) the only targets presented were angles for which the target point was the vertex. After the short presentation and a masking stimulus participants were shown a blank screen with the mouse pointer which they moved to the perceived location of the target. In Experiment 2 (N = 33) participants were presented with two out of three possible targets (vertex of an angle, top vertex of an isosceles triangle and the top left vertex of a square). After the masking stimulus participants were shown a blank screen with a cue which determined which of the two presented figures was the target. The results found no significant deviations from precise localization for angle vertices in both experiments and only a trend which was in line with the previous results for the polygon figures. We speculate that the incorporation of the manual response mode led to increased precision of angle vertex localization.
