Answer:
Functional Fixedness
Explanation:
Functional fixedness is simply a bias in human cognition that limits the way an individual uses an object only in the way it is designed or being used traditionally. This means that such people will only see an object as working in just one particular way, or the way it was created or manufactured. From the example, if Leon had kept on looking for the pin, then he is simply seeing things from a holistic point of view and has not overcome functional fixedness. Since he was able to make-do with wires to secure the deck, then he has overcome functional fixedness.
