Cognitive diversity, specifically system understanding, benefits teams in complex human-machine systems by improving performance and control. Team specialization did not show similar advantages, and conflict remained low.

Area of Science:

  • Human-Computer Interaction
  • Team Performance
  • Cognitive Psychology

Background:

  • Complex human-machine systems require effective teamwork.
  • Cognitive diversity is hypothesized to enhance team performance in such systems.
  • Understanding the specific types of cognitive diversity that benefit teams is crucial for system design.

Purpose of the Study:

  • To examine the effects of two types of cognitive diversity on team performance in a simulated spacecraft life support system.
  • To investigate the impact of system understanding and team specialization on task performance, system control, and communication.

Main Methods:

  • A PC-based simulation (Cabin Air Management System) was used to model a spacecraft life support task.
  • Seventy-two participants worked in two-person teams, with varying levels of system understanding (procedural vs. knowledge-oriented training) and team specialization.

  • Performance, knowledge, communication, and conflict were measured during fault scenarios.

    • Main Results:

    • Cognitive diversity in system understanding led to better primary task performance and more efficient manual system control.
    • Cognitive diversity related to team specialization did not yield performance advantages.
    • No significant effect of cognitive diversity on intra-team conflict was observed, with conflict levels remaining low.

    Conclusions:

    • System understanding is a beneficial form of cognitive diversity for teams operating complex human-machine systems.
    • Engineering cognitive diversity, particularly in system understanding, can enhance team effectiveness in critical operational environments.
    • The findings have implications for designing training and team structures for complex systems.
