At 3 months of age, reaching behavior was measured in a group of 10 girls and 10 boys born at term. The assessments were carried out on the average 2 days after reaching onset. Reaching kinematics was measured in both supine and reclined positions. Girls reached more than boys, had straighter reaching trajectories and movements of shorter durations as well as fewer movement units. The reclined position gave rise to straighter trajectories in both girls and boys. Several anthropometric parameters were measured. Girls had less length and volume of the forearm than boys but similar upper arm volumes. There was a weak relation between kinematic and anthropometric variables.
在3个月大时，对一组足月出生的10名女孩和10名男孩的够物行为进行了测量。评估平均在发病后2天进行。在仰卧位和斜倚位测量了够物运动学指标。女孩比男孩够物更多，够物轨迹更直，持续时间更短，运动单元也更少。斜倚位使女孩和男孩的轨迹都更直。测量了几个身体测量参数。女孩的前臂长度和体积比男孩小，但上臂体积相似。运动学变量和身体测量变量之间存在微弱的关系。
