We attempted to improve our apparatus for measurement of collision avoidance behaviors against a rolling ball and succeeded in measuring various parameters of the avoidance behaviors in a higher speed range of the rolling ball. Using this new apparatus, we were able to raise stepwise the ball speed up to the maximal speed limit (6.6 m/sec)calculated from the whole body reaction time of an average Japanese. The individual avoidable speed limit was defined as the maximal ball speed at which the subject was able to avoid collision before two successive failures. The avoidance behaviors of 38 primary school children and two adults were measured with this new apparatus. It has been shown that this new apparatus enables us to measure the maximal avoidable speed limit of the ball in addition to the collision occurrence rate and both shortest and mean reaction times of each subject, and that the measurement in the higher speed range of the ball is also applicable to adult subjects as well as to school children. These results indicated that this new apparatus could be applied to subjects of all age groups and would be able to perform more multifaceted functions in comparison to our original type because the new apparatus enables us to measure a new parameter, the maximal avoidable speed limit, by measurement in a higher speed range of the approaching object.
