More than just a utensil: The influence of drinking straw size on perceived consumption

This research replicates and extends Wansink and colleagues' research on the effect of container size on actual consumption by examining the influence of medium size of consumption (straw size) on perceived consumption. Results from two studies show that participants who used a thin straw perceived their consumption as greater than those who used a thick straw, because straw size can lead to different perceptions of consumption time. Furthermore, sip size does not moderate the effect of straw size on perceived consumption. Copyright Springer Science+Business Media New York 2013
