This study introduces a computer program to measure reaction time and accuracy in complex response tasks. The program analyzes fine motor skills and can help identify performance deficits, such as those seen in apraxia.

Area of Science:

  • Human-Computer Interaction
  • Cognitive Psychology
  • Neuroscience

Background:

  • Reaction time paradigms are crucial for assessing cognitive and motor functions.
  • Complex response tasks require precise coordination and timing.
  • Existing methods may not adequately capture nuanced performance deficits.

Purpose of the Study:

  • To develop and validate a computer program for assessing accuracy and response timing in a complex reaction-time task.
  • To provide a tool for analyzing fine motor skills and identifying performance distortions.
  • To enable the study of conditions like apraxia through detailed performance metrics.

Main Methods:

  • A reaction-time program was developed for IBM-PC compatible computers.
  • Subjects performed tasks involving stimulus pattern recognition and complex key presses.

  • The program recorded release time and response completion time, classifying errors.

    • Main Results:

    • The program accurately measures reaction time and response accuracy in complex tasks.
    • It allows for separate testing of left and right-hand performance.
    • Basic statistical characteristics of performance are computed and stored in ASCII format.

    Conclusions:

    • The developed program offers a robust method for evaluating reaction time and accuracy.
    • It serves as a valuable tool for research in cognitive psychology and neuroscience.
    • The program's design facilitates further data analysis with standard statistical packages.
