수평-수직 착시가 지각과 동작 제어에 미치는 영향

초록

Purpose: The purpose of this study was to analyze the effects of horizontal-vertical illusions on perception-action and to identify the differences between visually perceived results and perception in motor performance. Methods: The participants were 16 professional golfers and performed two experimental tasks. The first task was to check the length of the line visually, then walk in a blinded state and stop walking in a judged length. horizontal-vertical illusions were presented in three lengths (200 cm, 400 cm, 600 cm). The task was carried out 30 trials, 10 trials in both horizontal and vertical directions. The second task was golf putting that went on under three length conditions, such as walking. Performances on both tasks were analyzed through constant error (CE) of tasks according to horizontal-vertical and illusion line length conditions. Data were analyzed with Two-way ANOVA with factorial design by 2 (horizontal-vertical illusion) x 3 (line length). Results: Perceptual judgment tasks and golf putting according to the horizontal-Vertical illusion and line length were shown to be affected by the illusion. Conclusion: As the illusion occurred, the vertical direction was perceived to be longer than the horizontal and the action was performed longer than the actual length.
