先前的研究表明，感知距离是由身体的动作能力来衡量的。目前的研究表明，当“可达性”受到限制，由于一个困难的把握需要拿起一个对象，感知距离的对象增加。参与者估计的距离与处理方向，使他们容易或难以掌握他们的优势和非优势手的工具。右撇子的参与者认为更难掌握的工具比更容易掌握的工具更远。然而，感知距离在左撇子参与者中没有差异。这些研究表明，当到达目标时，到该目标的距离根据一个人可以有效到达的距离来缩放，给定执行的到达姿势的类型。此外，这种影响是由利手调制。
Previous research has suggested that perceived distances are scaled by the action capabilities of the body. The present studies showed that when "reachability" is constrained due to a difficult grasp required to pick up an object, perceived distance to the object increases. Participants estimated the distances to tools with handle orientations that made them either easy or difficult to grasp with their dominant and nondominant hands. Right-handed participants perceived tools that were more difficult to grasp to be farther away than tools that were easier to grasp. However, perceived distance did not differ in left-handed participants. These studies suggest that, when reaching toward a target, the distance to that target is scaled in terms of how far one can effectively reach, given the type of reaching posture that is executed. Furthermore, this effect is modulated by handedness.
