Transfer Studies of Analogical Problem Solving

Overview of Transfer

  • Transfer of learning often involves analogical transfer, particularly in ill-defined problems.

  • Analogy: A mechanism for structured comparisons of mental representations (Holyoak, 2012).

  • Analogical thinking involves transferring knowledge by mapping correspondences between different situations (Gick & Holyoak, 1983).

Radiation Problem

  • Duncker's Radiation Problem (1945): A doctor must destroy a malignant tumor with rays without harming healthy tissue.

    • High intensity destroys both tumor and healthy tissue.

    • Low intensity does not affect tumors.

  • Solution Structure: Similar to the Fortress problem where an army splits and converges simultaneously.

  • Solution for Radiation Problem: Use multiple lower-intensity rays to converge on the tumor.

Research Findings by Gick & Holyoak

  • Investigated the influence of previous analogous problems (Fortress problem) on solving the Radiation problem.

  • Results showed various suggested solutions based on the solution types presented in the Fortress problem.

    • Different strategies (e.g., open supply route, tunnel) led to varied responses for the Radiation problem.

  • Divide and Converge Solution: Effective strategy derived from the Fortress problem, pertaining to reduced ray intensity and multiple machines.

  • Notable statistic: Without hints, only 10% in control group solved analogically; with hints, 75-80% solved using the provided analogy.

Obstacles in Analogical Problem Solving

Retrieval

  • Accessing Past Experience: Major challenge present when problems are from different domains (e.g., military vs. surgical).

  • Cross-domain analogies can be fruitful but require effective retrieval strategies.

  • Example: Checklist systems from aviation implemented in healthcare to reduce errors (WHO Surgical Safety Checklists).

Mapping

  • Mapping involves establishing a structural alignment between problems.

  • Requires matching elements that play similar roles (e.g., general to surgeon, army to rays).

  • Candidate inferences projected from base (source problem) to target (current problem), allowing knowledge transfer.

Adaptation and Application

  • Adapting a past solution to a current problem can be challenging.

  • Difficulties can include pre-existing knowledge biases or unnecessary constraints imposed on problem statements.

  • Example: Misinterpreting resources available (e.g., number of ray machines).

Types of Similarity in Problems

  1. Identities: Elements that are the same in both problems.

  2. Indeterminate Correspondences: Elements yet to be matched or clear inferences.

  3. Structure-Preserving Differences: Surface differences that do not alter the solution structure.

  4. Structure-Violating Differences: Changes that impact the foundational solution.

Semantic Similarity and Its Impact

  • The more semantically similar the objects in different problems, the more likely an analogy will be utilized effectively.

  • Different analogies (e.g., beams of light vs. armies attacking) signal different approaches to problem-solving.

Cognitive Processes in Analogical Problem Solving

  • Requires deep-level comparison and similarity recognition of goals and relationships.

Conclusion

  • Recognizing structural similarities and mapping between problems can enhance problem-solving ability.

  • Analogies assist in both knowledge retention and concept understanding, influencing overall cognitive processes.
