用眼睛判断，人们高估了土豆的厚度，低估了切成薄片的土豆。在这项研究中，通过问卷调查对这种误解的三个可能原因进行了检验：薄片的数量越多，可能意味着数量越多，或者它们可能与土丘的高度或盘子的覆盖率相匹配。受试者镀了三种不同厚度的芯片，以匹配标准样品。正如预期的那样，对于较薄的芯片，芯片的重量较小，但芯片覆盖的表面积受到的影响相对较小，这表明受试者是通过盘子覆盖率来判断的，并在被询问时证实了这一点。
People overestimate thick and underestimate thin chipped potatoes when judging by eye. Three possible causes of this misperception have been tested by questionnaire in this study: the greater number of pieces of thin chips may suggest that there is a greater amount or they might match the height of the mound or the plate coverage. Subjects plated three different thicknesses of chips to match a standard sample. The weight of the chips was less for thinner chips as expected, but the surface area covered by the chips was relatively less affected, suggesting that subjects were judging by plate coverage and confirmed this when questioned.
