Question

You go to the movie theater after eating dinner and smell the popcorn in the concession stand. although you are full, you start salivating and your stomach grumbles, so you buy a bag to eat during the show. this is an example of what signal for eating?\

Answer 1

The urge to eat popcorn at the theater despite being full is a conditioned response known as the cephalic phase of gastric control, where the smell of food triggers the autonomic nervous system preparing the body for digestion. This psychological hunger is influenced by sensory cues and is different from physiological hunger, which is regulated by hormones signaling the brain about the stomach's fullness.

Step-by-step explanation:

When you smell popcorn at a movie theater and begin to salivate despite having a full stomach, your body is exhibiting a reaction known as the cephalic phase of gastric control. This reaction is a conditioned response triggered by the senses, such as smell and sight, and is a classic example of Pavlovian conditioning. The scent of popcorn leads to salivation and stomach grumbling because your autonomic nervous system is stimulated, preparing your body for digestion, even though your brain has signaled that you are satiated. This reaction is not an actual physiological hunger signal since your stomach is already full, but rather a psychological response to sensory cues.

Hormones play a crucial role in regulating digestion by signaling to the brain whether the stomach is full or empty. However, our brain also responds to external factors like the sight, smell, or even thought of food, which can sometimes disrupt the normal regulation of hunger and satiety. This is why we may feel the urge to eat, driven by environmental cues or psychological hunger, even when we are not physiologically in need of food.

While this is a natural response, it can lead to overeating and is not always a healthy behavior because it disregards the actual nutritional needs of the body. Being mindful of the difference between psychological hunger and actual physiological hunger can be important for maintaining healthy eating habits.

Answer 2

This is an example of "appetite".

Appetite refers to the desire or want to eat food, some of the time because of hunger. Engaging nourishments can empower craving notwithstanding when hunger is missing, in spite of the fact that craving can be significantly lessened by satiety. Appetite exists in all higher living things, and serves to manage sufficient vitality admission to keep up metabolic requirements.
