A new Automated Performance Test System (APTS) offers a standardized method to assess how workplace stressors and substances like alcohol impact human performance. This tool aids in identifying potential safety risks and performance degradation.

Area of Science:

  • Occupational Health
  • Human Performance Measurement
  • Toxicology

Background:

  • Workplace safety concerns are rising due to substance use and environmental stressors affecting operator efficiency.
  • Existing methods for assessing human performance degradation are not standardized or sensitive enough for systematic study.
  • A need exists for a reliable tool to evaluate the impact of various agents on human performance.

Purpose of the Study:

  • To develop a standardized, sensitive, and comprehensive human performance assessment battery.
  • To create a menu of tests within a coherent hardware and software package for repeated-measures studies.
  • To systematically investigate the effects of toxic chemicals, drugs, and environmental stressors on human performance.

Main Methods:

  • Development of a menu of 40 tests from the Automated Performance Test System (APTS).
  • Utilizing laptop portable and desktop personal computers for test administration.
  • Conducting interlocking studies to validate the test battery's stability, reliability, and predictive validity.

    • Main Results:

    • The APTS tests demonstrated stability, reliability, and factorial richness.
    • APTS showed predictive validity with measures of intelligence and simulator performance.
    • Sensitivity studies confirmed APTS's ability to detect performance changes caused by stressors, agents, and treatments.

    Conclusions:

    • The APTS provides a robust tool for assessing human performance degradation.
    • APTS can be used in repeated-measures studies to evaluate a wide range of performance-degrading agents.
    • APTS holds potential as a screening adjunct to urine testing for individuals in safety-sensitive positions.
