For problem solving, this is usually straightforward. In psychology, algorithms are frequently contrasted with heuristics. Learn vocabulary, terms, and more with flashcards, games, and other study tools. While algorithms provide stepbystep procedures that can guarantee solutions, heuristics are faster and provide shortcuts for getting to solutions, though this has. In cognitive psychology, the term problemsolving refers to the mental process that people go through to discover, analyze, and solve problems. In psychology, problem solving refers to a way of reaching a goal from a present condition, where the present condition is either not directly moving toward the goal, is far from it, or needs more complex logic in order to find steps toward the goal.
