プレッシャーが知覚および運動プランニングに及ぼす影響

Abstract

The purpose of this study was to clarify how psychological pressure impacts on perception, motor planning and performance. Fourteen male college students (mean age 21.5, sd=1.6 years) performed 2 tasks in succession under both no-pressure and pressure conditions; the perception task required them to judge the perceptual distance to the target, while the action task required them to putt a golf ball, aiming for the perceived target location. We measured the perceived target distance (subjective perception), displacement and maximum velocity of the club head (motor planning), and putting distance (motor performance) during the tasks; the target was created using Muller-Lyer illusion figures that induced distorted depth perception. While this form of pressure did not affect subjective perception, the illusion influenced subjective perception, i.e. F (1, 13)=24.25, p
