The craving for bread triggered by its aroma, even when full, is an example of what?

The craving for bread triggered by its aroma, even when full, is an example of appetite. Appetite refers to the desire to eat food, which can occur independently of physiological hunger. It can be influenced by various factors such as the sight and smell of food. In this scenario, the aroma of bread stimulates a psychological response that leads to a craving for it, despite not needing additional food for energy or sustenance. This distinction is important, as appetite often involves emotional and sensory cues that can prompt eating, independent of the body's actual energy needs.

In contrast, hunger is primarily a physiological response signaling the need for food due to energy depletion. Thirst relates to the body's need for hydration, and desire is more general, lacking the specific context of craving food.
