摘要
考察了人通过视觉和听觉获得的信息来感知物体重量水平的能力。操作者模特提举和搬运7个同样大小但重量水平不同的箱子,实验人员对搬运过程进行录音和录像,然后作为刺激材料呈现给被试并要求其给出每个箱子的主观重量评分。男女各20名被试参加了实验。结果表明:(1)人通过听取操作者搬举重物时的脚步声来判断其重量并不可靠,只能粗略地判断"轻"和"重"两种水平,分界线约20kg;(2)人类可以通过视觉(包括操作者的姿势和运动特点)较为可靠地判断重物的重量水平。
The purpose of this study was to examine human＇s weight perception from auditory and visual displays. Two experiments were conducted by using seven boxes with same volume but different weight. A model operator was asked to carry the seven boxes respectively between two platforms and in this carrying process both the sounds and the videos were recorded. Subjects were required to judge the weight level scores of the seven boxes in listening to the sounds and viewing the videos, respectively. Twenty male and 20 female subjects were involved in this research. Results showed that： （1） from sounds, people could only roughly distinguish two classes of weight ： ＂light＂ and ＂heavy＂, the boundary of the two classes was about 20kg; （2） from video information, subjects could reliably discriminate levels of weight.
