| Summary: | 碩士 === 明志科技大學 === 工業工程與管理系碩士班 === 106 === This study examined how container characteristics influenced the perception of volume under different light and color combinations. Sixty participants poured a certain amount of wine or water (100 or 200 mL) into a designated goblet according to their perception under 2 lighting levels (i.e., bright and dark). The results showed that four pairs of containers caused significant differences on volume perceptions, whereas the lighting effect was only observed in elongation tumblers and color effect in paired size goblet and elongation tumblers. Besides small, tall-slender, and short-wide tumblers, the volume perception of other containers significantly varied with genders, and the males consistently exhibited higher volume perception than the females. The participants’ academic background did not affect the volume perception. The volumes poured in the large tumbler and the tall-slender goblet were26% and 13% more than the target volume. These findings suggested that these 2 containers should be cautiously used to avoid over-drinking. By comparing with previous studies, it was found that a slight difference in container shape or the experimental design may affect the perceived volume, and the effects were also compounded by the variables of light, color, and gender. Therefore, this study suggests that, in practical applications, to clearly understand the actual situation and purpose of these containers is necessary to make the illusive effect in line with our expectations.
