When people relate to different things using their senses, multiple sensations are sent to the brain. Since these numerous amounts of sensations are sent to the brain, how they will be perceived remains unknown. How will something a person may have seen, heard, touched, tasted, or even smelled later affect their actions? The way things are interpreted will not always end up being something positive. For example, a person may have witnessed something they didn't agree with or saw something that went against what they believed and begin to engage in negative behavior as a protective instinct. People's visions obtain images that others may not be able to see with their own eyes, causing them to "create bipolar dimensions, such as 'hot versus cold' or 'good versus bad' as tools for making meaning of experience and anticipating events futures” (McWilliams, p. 154). Research has been completed to show how behavior changes during travel, due to sensation and perception. According to research, “the concept of perceived risk was introduced into the discipline of consumer behavior” (Walters, p. 544) . These risks were later classified as psychological risk, physical risk, and performance risk. The dramatic impacts on risk have led some tourists to question whether or not they should travel. Some tourists were very eager to travel while others were hesitant and needed more information before continuing the process. Their vision allowed them to see the task in front of them, which made everyone see the risk and have a different impact. Everyone's behavior will never be completely the same. People's sense levels are not all the same, so the way their sensations are perceived will always be original
