The wrong representation can hinder your ability to solve a problem, especially if you become stuck on that one interpretation. This barrier is called :

  • A.The representational problem
  • B.Algorithm interference
  • C.A blocked solution path
  • D.Functional fixedness

Answer: D

The key calls this barrier functional fixedness.

Functional fixedness is the tendency to see an object only in terms of its usual function, which stops the solver representing it in the new way the problem needs. Duncker's candle problem is the classic case: people fail to see the box of tacks as a shelf because they represent it only as a container. Being stuck on one interpretation is exactly that kind of fixed representation.

An algorithm is a step-by-step procedure that guarantees a solution, not a barrier, and 'algorithm interference', 'blocked solution path' and 'the representational problem' are not the standard name of this barrier.
