托福口语 Task 3

In psychology, the concept of 'functional fixedness' refers to a cognitive bias that limits a person to using an object only in the way it is traditionally used. This mental block prevents individuals from imagining alternative uses for familiar objects, thereby hindering creative problem-solving. When faced with a novel challenge, people often fail to see beyond an object's standard function, even if that function is irrelevant to the task at hand. Overcoming functional fixedness requires a deliberate shift in perspective, allowing one to re-evaluate the properties of objects and consider unconventional applications.

Professor: Let me give you a classic example from a study. Participants were given a candle, a box of thumbtacks, and a book of matches. Their task was to attach the candle to a wall so that it could burn without dripping wax on the floor. Many tried to tack the candle directly to the wall or melt wax to stick it—both failed. The solution was to empty the thumbtack box, tack it to the wall as a platform, and place the candle inside. But here's the catch: in one version, the thumbtacks were presented in the box; in another, they were laid out separately on a table. People who saw the box as a container for tacks struggled, because they saw it only as a holder. Those who saw the tacks separate immediately used the box as a shelf. The key was overcoming the fixed idea that a box is only for holding tacks.
