This study aimed to determine whether the interception of a moving object is achieved by implementing a predictive or a prospective strategy. We examined the kinematics of catching movement in a situation in which the catching hand was constrained to move along a single dimension. In line with predictions based on a prospective strategy, the results obtained indicated that, for the same interception point and the same initial hand position, modification of the spatiotemporal characteristics of the ball's trajectory (via modification of the angle of approach of the ball) gave rise to systematic changes in the kinematics of catching movement. Moreover, the production of movement reversals when the hand was already positioned at the interception point, while in line with the predictions of the prospective strategy formalized by Bootsma et al. (1997), allowed for rejection of a predictive strategy.
本研究旨在确定拦截移动物体是通过实施预测策略还是前瞻性策略来实现的。我们研究了在接球手被限制沿单一维度移动的情况下接球动作的运动学。与基于前瞻性策略的预测一致,所得结果表明,对于相同的拦截点和相同的初始手部位置,改变球的轨迹的时空特征(通过改变球的接近角度)会导致接球动作的运动学发生系统性变化。此外,当手已经位于拦截点时产生的动作反转,虽然符合博茨马等人(1997年)形式化的前瞻性策略的预测,但却排除了预测策略。
