先前的研究已證實炒鍋大小對於廚師的重量知覺具有大小重量錯覺的效應，然而對於廚師經常使用的湯鍋，是否具有大小重量錯覺的效應並沒有被正式的研究與規範，所以本研究乃針對湯鍋大小對於廚師的重量錯覺之效應進行研究。本研究共徵募12位男性受試者進行湯鍋的抬舉作業，以探討在不同湯鍋大小(直徑30，36及45 cm)及質量(3.0，6.6 及13.8 kg)下相對於標準刺激(直徑40 cm，9.0 kg)之重量知覺、體積知覺和施力知覺的效應。資料經收集分析後，發現湯鍋大小對於重量知覺、體積知覺有顯著效應，但對於施力知覺則無顯著效應。而質量對於重量知覺、體積知覺和施力知覺皆有顯著的效應。整體而言，當質量相同時重量知覺會隨著湯鍋大小的增加而減少；湯鍋大小從直徑30公分增加至45公分時，其重量知覺下降約10.83 %，顯示大小/重量錯覺存在於湯鍋作業之中。

Previous studies showed that the effect of wok size on the size-weight illusion was significant. However, until now this size-weight illusion of the soup pot size has not been formally studied and standardized. Therefore, the purpose of this study is to investigate the size-weight illusion of the size of soup pot. A total of 12 male subjects were recruited to conduct lifting task, and to investigate the perceived heaviness, perceived volume, and perceived exertion of the different combinations of the size of soup pots (diameter of 30, 36 and 45 cm) and mass (3.0, 6.6 and 13.8 kg) relative to the standard stimulus(40 cm, 9.0 kg). After collecting and analyzing the data, it was found that the soup pot size had significant effect on the perceived heaviness and perceived volume, but it had no significant effect on the perceived exertion. While the effects of the mass on the perceived heaviness, perceived volume, and perceived exertion were significant. Overall, the subjects perceived larger soup pots to be light than smaller soup pots of the same mass. As the volume of the stimuli increased from 30 cm diameter to 45 cm diameter, the reports of perceived heaviness deceased by about 10.83%. The result showed that the size-weight illusion exists in the soup pot lifting for chefs.
