human sensory level of food is lessened and there is more focus on the issue of survival Tip: Never go to the grocery store while hungry!
Media/Advertising: National Brands highly advertised might be popular but are not actually better than the store brand. Our brain may subconsciously identify a well-known brand as better, affecting our perception
