High-level visual-spatial ability is crucial for surgical novices. Stronger spatial skills correlate with better performance in complex simulator tasks during early training phases.

Area of Science:

  • Surgical Education
  • Medical Simulation
  • Cognitive Science in Medicine

Background:

  • Surgical training increasingly relies on simulators.
  • Visual-spatial ability is a key cognitive skill for surgeons.
  • The impact of visual-spatial ability on simulator performance needs further investigation.

Purpose of the Study:

  • To investigate the relationship between visual-spatial ability and performance in two surgical simulator tasks.
  • To determine if visual-spatial complexity of tasks influences this relationship.

Main Methods:

  • 54 surgical novices completed visual-spatial tests (Mental Rotation Test, BasIQ).
  • Participants performed two simulator tasks: Key Surgical Activities (KSA) and Minimally Invasive Surgical Trainer (MIST).

  • Pearson's r correlations were used to analyze the relationship between test scores and simulator performance.

    • Main Results:

    • Visual-spatial scores from MRT-C correlated with Instrument Navigation (IN) performance in KSA.
    • BasIQ scores showed significant correlations with both initial and final performance in IN (KSA).
    • Performance in MIST was not significantly correlated with visual-spatial scores in this study.

    Conclusions:

    • High-level visual-spatial ability is important for surgical novices in the early stages of learning complex simulator tasks like KSA.
    • These findings highlight the need to consider visual-spatial skills in surgical training programs.
