My experiment is based on changing the colour of the same flavoured food and determine if it affects people’s perception of its taste. I asked my participants to taste the same flavour of jello but in three different colours. Then I asked them to rate which colour was unappealing and which tasted the best. I hypothesize that if I change the colour of the same flavoured jello then their perception of taste will hopefully change. I used three different colours of jello and all were the same flavour. So by changing the independent variable, which is the colour, I wanted to observe
if the dependent variable, the person’s perception of taste, changes. My results determined that even though all the jello was the same flavour, 93.3% of people sampled said that each colour was a different flavour. For example, by looking at my pie charts I could see that most people thought that the orange coloured jello tasted like orange and the red tasted of strawberry. In conclusion, I could tell that our eyes influence what we taste before we taste it.
