Problem Solving

What is a Problem?

  • A problem arises when an obstacle stands between the present state and the goal, with the solution not immediately obvious.

Gestalt Approach: Problem Solving as Representation and Restructuring

  • Problem-solving involves (1) representing a problem in the mind and (2) reorganizing or restructuring this representation.
  • Restructuring: Changing the problem's representation.
  • Insight: The sudden realization of a problem’s solution, often involving restructuring.
  • Metcalfe and Wiebe (1987) demonstrated that solutions for insight problems occur suddenly.
  • Obstacles to problem solving include fixation, such as functional fixedness (focusing on familiar uses of objects).
  • Mental set: A preconceived notion about approaching a problem based on past experiences.

Information-Processing Approach: Problem Solving as a Search Process

  • Newell and Simon (1972) viewed problem-solving as a search process involving initial and goal states, operators, intermediate states, and problem space.
  • Means-end analysis: Reducing the difference between initial and goal states by creating subgoals.

Importance of Problem Statement

  • How a problem is stated can significantly affect its difficulty.
  • The mutilated checkerboard problem illustrates that providing information that points people toward the correct representation makes the problem easier to solve.
  • Think-aloud protocol: Participants verbalize their thoughts while solving a problem to reveal their thought processes.

Using Analogies to Solve Problems

  • Analogical problem solving: Using the solution to a similar problem to guide the solution of a new problem.
  • Analogical transfer: Transferring experience from solving one problem to solving another similar problem.
  • Gick and Holyoak’s (1983) three steps of analogical problem solving:
    1. Noticing the analogous relationship.
    2. Mapping the correspondence.
    3. Applying the mapping to generate a parallel solution.
  • Analogical encoding: Comparing two problems and determining similarities between them to understand the underlying structure.
  • In vivo problem-solving research: Observing people to determine how they solve problems in real-world situations.

How Experts Solve Problems

  • Experts solve problems faster and with higher success rates due to better knowledge and its organization.
  • Experts categorize problems based on structural features (underlying principles), while novices use surface characteristics.
  • Experts spend more time analyzing problems initially.
  • Expertise is only advantageous within the expert's field.

Creative Problem Solving

  • Creativity involves producing original and useful solutions.
  • Divergent thinking: Open-ended thinking involving a large number of potential solutions.
  • Creative problem-solving often involves analogical thinking.
  • Creative problem solving includes a lengthy period of trial-and-error development.
  • Knowledge is essential but sometimes too much knowledge can hinder creative problem solving.
  • Brainstorming: Freely expressing ideas without criticism.
  • Individual brainstorming and creative cognition techniques can be effective.
  • A positive mood and physical exercise may facilitate creative thinking.

Creativity, Mental Illness, and the Open Mind

  • Reduced latent inhibition (LI) is associated with being more open to stimuli and with mental illness and enhanced creativity.
  • Snyder (2009) proposed that savant skills are linked to reduced top-down inhibition in the brain.
