Which of the following are methods of solving problems ?
1. Trial and error
2. Mental set
3. Algorithm
4. Heuristics
5. Functional Fixedness
Codes :
Answer: C
The methods of solving problems are trial and error, algorithms and heuristics, so the set is 1, 3 and 4. Trial and error tries responses until one works, an algorithm is a step-by-step procedure that guarantees a solution, and a heuristic is a rule of thumb that is quicker but not guaranteed. Mental set and functional fixedness are not methods; they are obstacles, in which a habitual approach or the fixed use of an object blocks the solution. Options containing 2 or 5 are therefore wrong.
