Why is the sound of crispy food, such as chicken skin, roasted pork belly, chips, etc., appealing and mouthwatering?
In: Biology
This is likely a fact of mere association. In the same way then sound of opening a drink can triggers craving or thirst.
In one if the most groundbreaking biology experiments of all time, Ivan Pavlov would ring a bell whenever he served food to experimental dogs. After repeating this for a few weeks he observed that merely ringing the same bell would cause the dogs to salivate and act agitated/excited regardless of any other context. The dogs had been conditioned to associate the ringing bell with the function of eating.
This lead to the discovery of the Parasympathetic Nervous system.
