Penn psychologists believe 'unit bias' determines the acceptable amount to eat

public or private settings. In their study, they presented unsuspecting people with M&M's candies, Tootsie Rolls and Philadelphia-style soft pretzels. When changing the size of the portions whether by offering a whole or half of a pretzel, for example people will see the offered portion as a single unit. In the pretzel experiment, people would take and eat an entire pretzel even though they were eating twice as much as the other people who were sufficiently satisfied with a half pretzel as a single unit.

They also observed how the means of serving the portion could influence how much food is eaten. In the M&M's experiment, the researchers offered a large mixing bowl of the candy at the front desk of the concierge of an apartment building. Below the bowl hung a sign that read "Eat Your Fill" with "please use the spoon to serve yourself" written underneath.

If presented with a small spoon, most passersby would take a single scoop, even though the sign encouraged them to take more. If given a much larger spoon, the subjects would still take a single scoop, even though that one scoop contained much more candy. The subjects were inadvertently eating twice as much candy when the larger scoop happened to be in the bowl.

"It is more than just people afraid of appearing greedy. They didn't know they were being observed," Geier said. "We have a culturally enforced 'consumption norm,' which promotes both the tendency to complete eating a unit and the idea that a single unit is the proper amount to eat." The researchers believe a better understanding of unit bias will aid in studying the psychology of obesity.

"When we talk about overeating and obesity, we talk calories consumed and grams of fat, but we rarely mention context and environment what people see as the acceptable amount to eat," Geier said. "There are environmental elements that dramatically affect the choices and quantities of food we consume. This is a fundamental aspect of
