The effects of coloured food and gender on taste perception of spicy foods
Evolution has impacted a multitude of mechanisms in humans with the purpose of increasing the likelihood of survival. One of these mechanisms seems to be the development of the relationship between visual input and taste perception. In a study by Shermer and Levitan (2014), colour intensities of spicy foods were shown to influence the perception of spiciness. In conjunction with the research conducted by Shermer and Levitan, the purpose of this study is to determine if the colour intensity of certain foods affect the perception of its spiciness and salivary production with the hopes of further understanding gender differences in spiciness perception.

An example of the question is “this food is… very spicy, spicy, neutral, a little spicy, not spicy at all.” At the top of the questionnaire, participants must write their age, their gender and their sex. The survey was administered on a printed page, each was written in Arial font, size 12. The participants were given pencil, eraser and questionnaire. We used 2100 cotton balls, that were all new and used only once. We weighed them with the same electronic scale each time. Each participant had a total of 21 cotton balls, three per trial. The control group and the experimental group received the same treatment and the same conditions until they receive the foods. The food of choice here were spicy and non spicy salsas. Some salsas had red colouring and some had no colouring. The colouring was non-harmful, food dye. Some of the dyed salsas are more spicy that the non-dyed, but some of them are equal in piquancy to the non-dyed salsas. There were 2 non-spicy salsas, 2 spicy salsas and 2 very spicy salsa. One of the non-spicy salsas was dyed red as was one of the spicy salsas. The dyed piquancy salsa had the same level of spiciness as the other salsa of its category. The non-piquancy salsas were the same, although one was dyed red and the other wasn’t. One of the very spicy salsas was dyed red and the other one wasn’t. The experimental group gets both the dyed and undyed salsas, whereas as the control group only gets the non-dyed salsas. The latter, nevertheless, will taste the 6 salsas, they simply will not be

The scientists will conduct the experiment by taking four cups of water one that is just salt mixed with water, another that is just water, a third cup that is just ice water and finally a forth cup that is vinegar and water mixed. After that the scientists will drop one Alka-Seltzer tablet into each cup and see how long it takes for it to completely dissolve. The scientists will conduct these three times for
A lot of lesson in this experiment, one is that people like different flavor of gum for different reasons, and two not all Gums are the same. Our possible source of error is that we could

The Questionnaire we constructed included several different question types, such as Likert, so we could gather the most accurate data. The first couple of questions we asked were simple questions to understand the person taking the survey. Some of these questions included gender and age range. These questions made us aware of the demographics taking the questionnaire. Then we included questions that gave us insight on how frequently they ate fast food and how frequently they visited Chick-fil-a. Some examples of these questions were, how far they lived from a Chick-fil-a, what meal they usually eat at a fast food restaurant, and how many times a week they eat Chick-fil-a. For the next section of our questionnaire there were Likert scaled questions
Five hundred and seventy eight of the students were from a Mexican background, while one hundred and seventy two were Chinese, and one hundred and seventy one were European. Fifty two percent of the students were girls, while forty-eight percent were boys. DESCRIBE THE METHOD/S USED TO EXAMINE THE HYPOTHESIS The researchers chose to use an initial background questionnaire that was given to each of the schools and then the students were asked to use a daily diary checklist that was to be used at the end of each day over a fourteen day period. The students were asked to report their emotions and keep a record of any events had occurred that day with either parents or family members, friends, or significant others.

The participants gathered in one school’s cafeteria, and were given a choice of an English or Spanish survey. Only one participant chose the Spanish version. The researchers were available to answer any questions, and also checked each survey as it was turned it to make sure the results were of value. The surveys used were

In this particular experiment the constant condition, the factor that was never changed, was the room temperature water. The independent variable, the variable the student affected, was how much water was placed into the beakers. The dependent variable, a variable that was affected by the independent variable, was the time it took for the tablet to fully dissolve. The control group, which did not receive treatment from the students, was the 50 ml of water as a result of being the medium between the three measurements of water. Finally, the experimental group, the subject that was exposed to the variable during the experiment, was the 25 ml and 75 ml of

Two days before the experiment, participants were nude-weighed to calculate the amount of energy drinks they had. The rugby players did the same exercise every time before a test. They were told to keep away from caffeine, and alcohol two days before the test. On the day of the experimental trials, participants ate three hours before they began the tests. Before the game, urine samples were collected from the players.
They might not be the exact recipes that the Spaniards, Native Americans and Mexicans used, but they have been remodeled and improved to be created and enhanced as the years go by. This also goes to American food but now that many new cultures have been presented in the United States there is going to be new food mixtures that may contain half the taste of one certain region to the other. Which means that there might be more food that begins to get spicy around places such as Arizona, California, Utah and New
The participants were from different ethnicities included Caucasian, Vietnamese, German/Welsh, Mexican and Indian. The participants were asked individually in person to volunteer. No, volunteer received any kind of extra credit as it was not a class requirement. There were 4 males and 6 females participating in the experiment. Excel spreadsheet was used to collect final experiment results and responses from demographic questions for each of the participants.
