| Abstract(in English) | We investigated the effect of the appearance of cut food on visual weight estimation. In the experiment, we manipulated the shape (a block, fine strips, or small cubes) of food samples of various weights, and presented them on a CRT display. Eleven subjects participated in tasks to choose the picture of the food sample which they felt indicated a target weight. We used raw carrots and surimi gel as hard and soft samples respectively. The results clearly confirm an existence of an illusion. Participants overestimated the weight of finely cut food, especially fine strips, whereas they could accurately estimate the weight of block samples, regardless of the physical characteristics of the foods. The overestimation of cut food increased with the food's weight, and was particularly obvious with increases of apparent volume when cut into fine strips. These results suggest that the apparent volume of a food sample effects the visual estimation of its weight. |
