📖 เนื้อเรื่อง
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 and creativity. Functional fixedness often arises from past experiences and habitual thinking, making it difficult to approach a problem with a fresh perspective.

Professor: Today, let's discuss functional fixedness with a real-life example. Imagine you are in a workshop and need to hang a picture on the wall, but you don't have a hammer. A nail is on the table, but you only have a heavy book nearby. Many people would feel stuck because they see the book only as something to read, not as a tool. However, a creative person might use the book's spine to tap the nail into the wall. In another case, suppose you need to tighten a screw but lack a screwdriver. A coin could work, but if you only think of coins as money, you won't consider using its edge. This shows how functional fixedness can block problem-solving. In a classic experiment, participants were given a box of tacks, a candle, and matches, and asked to attach the candle to a wall. Those who saw the box as a container struggled, but those who realized the box could serve as a platform succeeded. So, overcoming functional fixedness requires breaking mental habits.
