The current study examined whether young adults' avoidance behaviours differed when circumventing a larger versus smaller interferer. It was expected that avoidance behaviours (repulsion) would be affected by the interferer's size (i.e., greater repulsion for larger body size). Participants (n = 20) walked along an 8 m pathway towards a goal while avoiding either a larger or smaller sized male interferer who stood stationary facing forward, backward, left, or right and were located 2, 4, or 6 m from the participants' starting position. Results revealed that there was an effect of interferer body size (personal-characteristics) and orientation (situational-characteristics) on M-L clearance between the interferer and participant at the time of crossing, suggesting that repulsion magnitudes are scaled to an interferer's closest body surface.
当前研究考察了年轻人在回避较大和较小干扰者时的回避行为是否存在差异。预计回避行为（排斥）会受到干扰者大小的影响（即对于更大的体型会有更大的排斥）。参与者（n=20）在 8 米长的通道上朝着目标行走，同时避开站在前面、后面、左边或右边且位置在参与者起始位置 2、4 或 6 米处的较大或较小的男性干扰者。结果表明，在穿越时，干扰者的体型（个人特征）和方向（情境特征）对参与者与干扰者之间的左右（M-L）间隙有影响，这表明排斥力的大小与干扰者最近的身体表面成比例。
