The concept of 'functional fixedness' refers to the tendency of individuals to perceive objects only in their conventional roles, thereby limiting their ability to imagine alternative uses. This cognitive bias can hinder problem-solving because it prevents creative thinking about how familiar items might serve novel functions. Researchers suggest that overcoming functional fixedness requires deliberate cognitive effort to break away from habitual associations.
🎧 Listening Lecture
Professor: Let me illustrate this with a classic experiment. Participants were given a box of tacks, a candle, and a book of matches, and asked to attach the candle to a wall so that it could burn properly. Some participants received the tacks already spilled out of the box, while others received them inside the box. Those who saw the box as a container struggled. But those who saw the box as a potential shelf—by tacking it to the wall and placing the candle on top—solved the problem easily. The key was seeing the box not just as a container, but as a platform.
