表征动量（RM）是一种众所周知的现象，当运动物体突然消失时，其最终或消失位置的记忆会在其运动方向上向前移位。许多研究表明，RM在日常生活、运动、发育和衰老等方面具有各种感知和认知特征。在这里，我们研究了纵向发展变化的位移幅度的RM之间的年轻（5岁）和老年人（6岁）幼儿园儿童指向和判断任务。在我们的实验中，儿童被要求用他们的手指指向（指向任务）和判断的空间位置的消失点的运动刺激（判断任务）。我们的研究结果表明，RM的平均幅度显着下降，从5- 6岁的儿童为指向和判断任务，虽然RM的平均幅度显着更大，在5岁的儿童为指向任务，但不为判断任务。我们进一步研究了RM的发展变化的基础上，从本研究（5岁的儿童）和我们以前的研究（7岁和11岁的儿童和22岁的成年人）的数据范围广泛的年龄。这个特设的检查表明，RM的幅度显着大于5岁的儿童比成人的指向和判断任务。我们的研究结果表明，RM的幅度是显着大于幼儿比成人和显着下降，幼儿通过成人的指向和判断任务。
Representational momentum (RM) is a well-known phenomenon that occurs when a moving object vanishes suddenly and the memory of its final or vanishing position is displaced forward in the direction of its motion. Many studies have shown evidence of various perceptual and cognitive characteristics of RM in various daily aspects, sports, development, and aging. Here we examined the longitudinal developmental changes in the displacement magnitudes of RM among younger (5-year-old) and older (6-year-old) nursery school children for pointing and judging tasks. In our experiments, the children were asked to point at by their finger (pointing task) and judge the spatial location (judging task) of the vanishing point of a moving stimulus. Our results showed that the mean magnitudes of RM significantly decreased from 5- to 6-year-old children for the pointing and judging tasks, although the mean magnitude of RM was significantly greater in the 5-year-old children for the pointing task but not for the judging task. We further examined the developmental changes in RM for a wide range of ages based on data from the present study (5-year-old children) and our previous study (7- and 11-year-old children and 22-year-old adults). This ad hoc examination showed that the magnitude of RM was significantly greater in 5-year-old children than in adults for the pointing and judging tasks. Our findings suggest that the magnitude of RM was significantly greater in young children than in adults and significantly decreased in young children through adults for the pointing and judging tasks.
