A computer-based mouse response (CBMR) coding task effectively measures general processing speed (Gs), similar to traditional paper-and-pencil tests. This method avoids psychomotor variance and may reveal unique performance differences.

Area of Science:

  • Cognitive Psychology
  • Psychometrics
  • Neuroscience

Background:

  • General processing speed (Gs) is a fundamental cognitive ability.
  • Traditional measures of Gs often rely on paper-and-pencil (PP) formats.
  • The validity of computer-based assessments, particularly using mouse responses, requires investigation.

Purpose of the Study:

  • To determine if a computer-based mouse response (CBMR) speeded coding task measures general processing speed (Gs).
  • To compare the CBMR task with traditional Gs and reaction time tasks.
  • To assess if the CBMR format introduces psychomotor performance variance.

Main Methods:

  • A network analysis approach was employed.
  • Tasks included a novel CBMR speeded coding task alongside established PP Gs tests and reaction time tasks.

  • Statistical methods were used to analyze the relationships between tasks and assess construct validity.

    • Main Results:

    • The CBMR speeded coding task was shown to measure the same underlying construct as traditional PP Gs tests.
    • The CBMR format did not introduce significant variance attributable to psychomotor performance.
    • Observed differences between PP and CBMR formats suggest potential for capturing unique individual performance variations.

    Conclusions:

    • Computer-based mouse response (CBMR) coding tasks are valid measures of general processing speed (Gs).
    • This digital format offers a reliable alternative to traditional paper-and-pencil methods without compromising construct validity.
    • The CBMR format may provide novel insights into individual cognitive differences beyond traditional assessments.
