A psychology student is trying to determine if sight or taste influence perception of taste more predominately. She colors Jell-O with food coloring and gives blue
Jell-O to one group of students (although it is actually lemon flavor). The other
students have lemon Jell-O that is it’s normal yellow color. Many of the students
who taste the blue Jell-O report having tasted blueberry Jell-O.
