The concept of 'functional fixedness' refers to the tendency of individuals to perceive objects only in terms of their typical or intended use, which limits their ability to imagine alternative functions. This cognitive bias can hinder problem-solving because people fail to see novel solutions when familiar objects are involved. Overcoming functional fixedness often requires a conscious shift in perspective, allowing the mind to break free from conventional associations.
🎧 Listening Lecture
Professor: Let me illustrate this with a classic experiment. Participants were given a box of thumbtacks, a candle, and a matchbook, and were asked to attach the candle to a wall so that it could burn properly. Most people tried to pin the candle directly to the wall or melt wax to stick it—both failed. They were stuck because they saw the box only as a container for thumbtacks. However, the solution was to empty the box, tack it to the wall as a small shelf, and place the candle inside. Those who succeeded had to overcome functional fixedness by seeing the box not just as a holder, but as a potential platform. This demonstrates how breaking mental blocks leads to creative problem-solving.
❓ Question Using the example from the lecture, explain the concept of functional fixedness and how overcoming it can lead to a solution.
