Generating mental images after receiving a problem aids problem-solving by overcoming fixation. However, generating images before the problem may worsen these tendencies.

Area of Science:

  • Cognitive Psychology
  • Educational Psychology

Background:

  • Problem-solving can be hindered by misleading or fixating tendencies.
  • Visualization techniques are explored to improve cognitive task performance.

Purpose of the Study:

  • To investigate the impact of mental imagery generation timing on problem-solving.
  • To determine if generating images before or after problem presentation affects performance.

Main Methods:

  • Three experiments were conducted with secondary-school students and undergraduates.
  • Participants solved arithmetic, geometric, and practical problems under three conditions: control, imagery-before, and imagery-after.
  • Mental images were generated either before or after problem presentation.

Main Results:

  • The "imagery-after" condition generally helped subjects overcome fixating tendencies.
  • Conversely, the "imagery-before" condition appeared to enhance these interfering tendencies.
  • Performance varied across problem types and participant groups.

Conclusions:

  • The timing of mental image generation is crucial for effective problem-solving.
  • Generating visualizations after problem presentation is beneficial for overcoming cognitive blocks.
  • Pre-problem visualization may inadvertently increase problem-solving difficulties.
