Figure 1.
Two experimental glasses with the same capacity and amount of liquid (66% filled).
Due to the effect of elongation both pouring volume (b) and rest volume (a) appear larger in the tall narrow glass than in the short wide glass.
Table 1.
The mean quantity of lemonade poured and standard deviations (in grams), the mean percentage of the glass filled, the liquid level relative to the rim of the glass (in cm), the percentage of participants that poured more in the short wide than in the tall narrow glass (% ppnegative bias) as a function of instruction (pour a drink versus a shot), type of pourer (generous versus frugal) and glass shape (tall narrow versus short wide).
Table 2.
The mean quantity of water poured and standard deviations (in grams), the mean absolute error of the poured volume with regard to the required volume (in grams), the mean percentage of the glass filled, the liquid level relative to the rim of the glass (in cm), percentage of participants that poured more in the short wide than in the tall narrow glass (% ppnegative bias) as a function of Instruction (fill or leave space), Amount (small versus large) and Glass (tall narrow versus short wide).
