Outline of Final Research Achievements |
The purpose of this study was to examine the developmental effect and mechanisms of the perception of gravity on catching a falling ball, targeting from young children to adults. The main four results were: 1) catching stratagem (movement start time and tracking velocity) was not influenced by projection speed with advancing age; 2) regarding a coincidence timing task at 3 different falling velocities, the timing task was influenced by free fall with advancing age; 3) regarding movement of the head, young children were more affected by the orbit of the ball after projection when compared with adults; and 4) catching stratagem (movement start time and tracking velocity) was more affected by free fall with advancing age than other gravitational conditions (0.5 G, 2.0 G). This suggests that catching movements are influenced by an internal model of gravity, depending on the stage of development.
