The effect of taste preferences The influence of portion size on intake The tendency to finish meals quickly The habit of skipping meals

Correct Answer:

The influence of portion size on intake

Explanation:

Unit bias focuses on how the size of the unit you’re served shapes how much you think is appropriate to eat. When the units or plates are larger, people tend to treat that larger unit as the standard portion and end up consuming more, even if they’re not hungrier. In studies of portion control, this explains why simply increasing plate or packaging size can raise total intake—the boundary of the unit cues the amount to eat. This is different from taste preferences, which would drive eating based on flavor liking; or from finishing meals quickly, which concerns pace; or skipping meals, which involves meal frequency. So the idea captured here is that portion size itself influences how much people eat.
