TOEFLスピーキング Task 3

In psychology, the concept of 'functional fixedness' refers to the tendency to perceive an object only in terms of its most common use, thereby limiting the ability to imagine alternative functions for that object. This cognitive bias can hinder problem-solving because individuals fail to see novel ways to utilize familiar items. Overcoming functional fixedness often requires a deliberate shift in perspective or creative thinking to unlock unconventional solutions.

Professor: Let me illustrate functional fixedness with a classic experiment. Participants were given a box of tacks, a candle, and matches, and asked to attach the candle to a wall so it could burn properly. Many struggled because they saw the box only as a container for tacks. The solution was to empty the box, tack it to the wall, and place the candle inside. Those who saw the box as a platform—not just a holder—solved it easily. Another example: a screwdriver is usually for screws, but if you need to punch a hole in a can, you might use its handle as a hammer. People who are stuck on the screwdriver's typical function fail to see this. So, functional fixedness blocks creative alternatives until you mentally reframe the object's purpose.
