Study guide for Problem Space Theory: Cognitive Psychology exam prep

📚 Quick Study Guide

• 🗺️ Problem Space Theory, developed by Allen Newell and Herbert A. Simon, explains problem-solving as a search within a 'problem space.'
• 🧠 A 'problem space' consists of: initial state, goal state, operators (actions to change states), and intermediate states.
• 🎯 Problem-solving involves navigating from the initial state to the goal state by applying operators.
• ⚙️ Heuristics are mental shortcuts used to guide the search, like means-end analysis (reducing the difference between current and goal states).
• 💡 Limitations include: ill-defined problems (unclear goal state or operators) and computational complexity (the problem space can be vast).
• 📈 Think-aloud protocols are used to study problem-solving strategies by verbalizing thoughts during the process.
• ⏱️ The Tower of Hanoi puzzle is a classic example used to illustrate Problem Space Theory.
