A research consultant in a candy factory is developing exotic tasting jelly beans. He hypothesized that experiencing exotic flavors would increase liking for traditional candy flavors. First, he had participants come into the lab, one at a time, and allowed them to eat as many jelly beans as they wanted from a dish of 50 on the table. The flavors in the dish were cherry, tangerine, chocolate, lemon, and cotton candy. The next time they came into the lab, he mixed in new flavors that looked similar to the old ones but had unique flavors: rubber eraser, cough medicine, dirt, salt, pencil shavings. Finally, the same participants were brought in to the lab again to repeat the procedure from Time 1. The researcher kept track of how many jelly beans were consumed by each participant at each time, as shown in the table.
