How do you know what is edible and what isn’t? The answer to this question varies depending on which subfield of psychology a person chooses to view.

This means that a past or current experience with a certain food can cause your brain to reject that food. For instance, if a person eats something and then throws up, that person’s brain will associate that food with illness and cause the person to grow a disliking to it. This is possible even if the food is not the cause of the person throwing up. Another field of psychological research is cognitive psychology, which studies the processes of thought and knowledge. Research has shown that a person judges a food’s edibility on just the idea of it. For example, if something looks repulsive, but is still edible, most humans will reject that food. This psychology field offers an explanation as to why humans will not eat foods that sound or look disgusting to them despite the fact that they are edible. These three fields of psychology each offer an excellent explanation as to how humans decide what is
