An example of effective problem solving strategy is

  • A.Not paying any attention to evaluating the solution.
  • B.Functional fixedness – focusing on only the conventional function of an object.
  • C.Response set – getting stuck on one way of representing a problem.
  • D.Means-end analysis – dividing the problem into number of sub-goals.

Answer: D

An effective strategy is means-end analysis, dividing the problem into a number of sub-goals.

Means-end analysis, described by Newell and Simon, compares the current state with the goal, identifies the difference, and sets sub-goals that reduce it step by step. Breaking a large problem into manageable parts is a powerful general heuristic.

The other three are obstacles to problem solving. Failing to evaluate the solution leaves errors undetected. Functional fixedness, seeing an object only in its usual use, and a response set, being stuck on one way of representing a problem, both block the flexible thinking that new problems need.
