U PART II: Ice Cream Servings Researchers conducted a study in which they invited 90 nutrition experts to an ice cream social (Wansink et al., 2006). Thirty of these experts were randomly given a small (12 oz) ice cream bowl, thirty were randomly given a medium (20 oz) ice cream bowl, and the remaining thirty were given a large (32 oz) ice cream bowl. They were then invited to serve themselves ice cream. The data revealed that those with larger bowls substantially more ice cream than those with smaller ate bowls.
