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 seeing alternative uses for familiar objects, thereby hindering problem-solving. Functional fixedness often arises from past experiences and learned schemas, which create rigid associations between an object and its typical function. Overcoming this bias requires creative thinking and the ability to reframe the problem, allowing for novel applications of available resources.

Professor: Let me give you an example from a classic experiment. 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 it could burn properly. Some participants tried to melt the wax and stick the candle directly to the wall, but it didn't hold. Others tried tacking the candle to the wall, but the thumbtacks were too short. The solution, however, was to empty the thumbtack box, tack it to the wall as a platform, and then place the candle on top of it. But here's the catch: participants who received the thumbtacks already in the box were much less likely to solve the problem than those who received the thumbtacks and the box separately. Why? Because when the box was presented as a container, they saw it only as a container. They couldn't see its potential as a shelf. That's functional fixedness in action.
