Answer:
Functional fixedness
Explanation:
According to psychology, functional fixedness is a cognitive bias that limits a person to use an object only in the way it is traditionally used.
People with functional fixedness will not find new ways to use an object and will remain with just one particular use (usually the one it was intended to).
Therefore, the inability to see that something that is known to have a particular use may also be used for performing other functions is functional fixedness.
