Step-by-step explanation:
According to Dollard and Miller, Mark's hunger can be described as a drive. This psychological concept represents an internal state that motivates an individual to fulfill a need, in this case, the need for food. Seeing the signs of fast food restaurants acts as a cue, triggering Mark's recognition of his hunger and prompting him to take action to satisfy it. Hunger itself is regulated by a negative feedback loop in the body, wherein the stimulus (hunger) changes direction in response to a signal (fullness). The hypothalamus region of the brain plays a critical role in this process through the signaling of hunger and satiety. This physiological aspect of hunger is influenced by various factors, including the sight of food, which can act as a strong psychological cue.
