In a classic study of problem solving, Dunker asked participants to mount a candle on a wall in an upright position so that it would burn normally. One group was given a candle, a book of matches and a box of tacks. A second group was given the same items, exempt the tacks and box were presented separately as two distinct items. The solution to solve this problem involves using the tacks to mount the box on the wall, which crates as a shelf for the candle. Dunker reasoned that the first group of participants would have trouble seeing the new function for the box (a shelf) because it was already serving a function.
Here is the participant's time to solve the problem in seconds:
