摘要

本研究旨在探討國人在個人抬舉作業中之大小／重量錯覺效應。本研究總共有28位受試者（18位男性及10位女性）參與實驗，以探討在不同目標物大小（10^3、14^3及18^3立方英吋）及質量（3.0kg、6.6kg及13.8kg）下相對於標準刺激（16^3立方英吋，9.0kg）之重量知覺、體積知覺和施力知覺，研究結果發現質量對於重量知覺有顯著效應，但對於體積知覺和施力知覺則無顯著效應；而目標物大小對於重量知覺、體積知覺和施力知覺皆有顯著效應，顯示大小／重量錯覺存在於國人之個人抬舉中，當重量相同時重量知覺會隨著箱子目標物大小的增加而減少；目標物大小從10^3立方英吋增加至18^3立方英吋時，其重量知覺下降20％。此外，性別及國內外不同種族之間對於重量知覺皆無顯著的差異。

This study investigates the size-weight illusion effect on individual lifting. This study recruited twenty-eight subjects (18 men, 10 women) to conduct individual lifting and investigate the perceived heaviness, perceived volume, and perceived exertion of the different combinations of object size (10^3, 14^3 and 18^3 cubic inches) and mass (3.0, 6.6 and 9.0 kg). The mass significantly affected the perceived heaviness; however, it did not significantly affect the perceived volume and perceived exertion. The object size effects on the perceived heaviness, perceived volume and perceived exertion were significant. This result showed that a size-weight illusion exists in individual lifting for Chinese participants. As the volume of the stimuli increased from 10^3 to 18^3 cubic inches, individual reports of perceived heaviness decreased 20%. In addition, there were no significant ethnic or sex differences regarding these effects.
