令人惊讶的是，人们对如何计划和控制日常身体动作（例如行走和捡起物体）知之甚少。为了探索这个主题，我们进行了一项实验，要求大学生拿起一个常见的物体（儿童的沙滩桶），该物体位于距离参与者起始位置几米的桌子上。水桶位于桌子的左侧、中间或右侧，并且根据指示，将被运送到水平位置也不同的更远的目标。问题是参与者在拿起水桶时会沿着桌子的哪一侧走，以及参与者会用哪只手拿起并携带水桶。参与者大多是右利手，他们更喜欢沿着桌子的左侧行走并用右手拿起水桶，尽管当桌子对面的到达距离不舒服或目标距离右侧太远时，他们就会偏离这种偏好。这些数据与数学模型非常吻合，该模型包括右手偏差和功能距离估计，该估计表示到达一定距离的成本约为步行相同距离成本的两倍。
Surprisingly little is known about how people plan and control everyday physical actions, such as walking along and picking up objects. In order to explore this topic, we conducted an experiment in which university students were asked to pick up a common object (a child’s beach bucket) that stood on a table several meters from the participant’s start position. The bucket stood either on the left side, in the middle, or on the right side of the table and, depending on instructions, was to be carried to a farther target whose horizontal position was also varied. The questions were which side of the table the participant would walk along when picking up the bucket and which hand the participant would use to pick up and carry the bucket. Participants, most of whom were righthanded, preferred to walk along the left side of the table and to pick up the bucket with the right hand, although they departed from that preference when the reaching distance across the table was uncomfortable or if the target was too far to the right. The data were well fit with a mathematical model that included a right-hand bias and an estimate of functional distance that expressed the cost of reaching over some distance as approximately twice the cost of walking over the same distance.
