Study Notes

Problem-solving Recap

Problems arise when a desired state isn't immediately achievable from the current state.
Three key components of a problem are:
- Start state: Initial situation.
- End state: Desired outcome.
- Operators: Actions or processes to change the state.
A problem typically requires multiple steps, not just a single action.
Knowledge-lean problems:
- Require minimal prior knowledge.
- Solutions are generally applicable to various situations.
Knowledge-rich problems:
- Require extensive prior knowledge.
- Solutions are specific to particular types of problems.
Well-defined problems:
- Clear start and goal states.
- Specific allowed and disallowed operators.
Ill-defined problems:
- One or more parameters are unclear (e.g., start state, goal state, operators).

Approaches to Problem-solving

Gestalt approach: Emphasizes understanding the overall structure of the problem, not just individual elements.
- Insight: Sudden awareness of a solution.
- Restructuring: Altering the problem's structure.
Reproductive thinking:
- Applies previously learned problem-solving methods.
- Can be ineffective if it ignores alternative solutions.
Productive thinking:
- Emphasis on underlying problem structure understanding.
- Leads to insight and restructuring.
Problem-solving set:
- A habit of solving problems in a specific way.
- Can lead to overlooking simpler solutions.
Functional fixedness:
- Tendency to focus on objects' typical function.
- Can prevent seeing alternative uses.

Information-processing Approach

Problem space: Mental representation of the problem.
General Problem Solver (GPS): Computer program mimicking human problem-solving.
- Algorithmic method: Systematically searches for solutions.
- Heuristic method: Uses rules of thumb.
Means-ends analysis: Comparing current state to goal and finding steps to bridge the gap.
Limitations of the approach:
- Difficulty handling ill-defined problems.
- Struggle with simultaneous problems.
- Not inherently equipped to handle insight problems.

Use of Analogy in Problem-solving

Analogy: Adapting solutions from similar problems to solve a new one.
Factors affecting analogy use:
- Degree of similarity between problems.
- Context specificity of solutions.
Factors improving analogy effectiveness
- Explicit instruction to compare problems.
- Exposing participants to similar problems.
- Hints suggesting existing solutions applicability.
- Focusing on structural features rather than superficial content.
Limitations of analogy use in real-life:
- Difficulty aligning with the complexities of real-world problems.
- Distraction and multiple issues.

Problem-solving in Everyday Life

Everyday problems often differ from laboratory problems in being ill-defined, having multiple simultaneous problems, and requiring adaptable solutions.
Everyday problems may require more creativity and adaptation, and often have more tangible rewards.
