    Area of Science:

    • Surgical Simulation and Team Performance Analysis
    • Human-Computer Interaction in Medicine
    • Cognitive Science and Team Dynamics

    Background:

    • Team cognition significantly impacts performance, especially in complex procedures like laparoscopic surgery.
    • Shared cognition is critical for effective teamwork in surgical environments.
    • Understanding team member interactions is key to improving surgical outcomes.

    Purpose of the Study:

    • To investigate the relationship between team member delay and performance in laparoscopic surgery teams.
    • To analyze eye tracking data using Cross Recurrence Analysis (CRA) to quantify team cognition.
    • To differentiate between high-performing and low-performing surgical teams based on cognitive metrics.

    Main Methods:

    • Collected dual eye tracking data from 22 surgical dyads during a laparoscopic simulation.
    • Categorized teams into 'good performer' and 'poor performer' groups based on task completion time.
    • Applied Cross Recurrence Analysis (CRA) to eye tracking data to measure inter-member delay.

    Main Results:

    • Good performer teams demonstrated significantly smaller delays between team members compared to poor performer teams.
    • The observed delays correlate with gaze overlap, supporting the concept of shared cognition.
    • Cross Recurrence Analysis effectively identified cognitive differences linked to surgical team performance.

    Conclusions:

    • Reduced inter-member delay is a strong indicator of effective shared cognition in surgical teams.
    • Eye tracking analysis, particularly CRA, offers valuable insights into team dynamics and performance optimization.
    • Improving shared cognition through reduced delays can enhance laparoscopic surgical team effectiveness.
