Disabled individuals can maintain stable proofreading performance for up to six hours, even with high error density. This finding supports sustained attention capabilities in electronic data processing roles for diverse populations.

Area of Science:

  • Human-Computer Interaction
  • Assistive Technology
  • Cognitive Psychology

Background:

  • Optical Character Recognition (OCR) and data input technologies enable employment for disabled individuals in electronic data processing.
  • Sustained attention tasks, like proofreading, often show performance declines over time in functionally impaired populations.
  • Previous research suggests increased error density may improve proofreading performance.

Purpose of the Study:

  • To assess the sustained proofreading performance of a diverse group of disabled individuals.
  • To evaluate the impact of embedded errors on proofreading accuracy and stability over a prolonged period.

Main Methods:

  • A computerized proofreading task was administered to 12 disabled individuals with varied physical or psychological impairments.

  • Alphanumeric code with embedded errors was used for the proofreading task.
  • Subjects underwent extensive training before participating in a 6-hour proofreading session.

    • Main Results:

    • Subjects achieved a high overall error correction rate of 96.6% across 50,000 characters.
    • Proofreading performance, measured by error detection, remained stable throughout the entire 6-hour duration.
    • The heterogeneous group demonstrated consistent accuracy despite a broad range of impairments.

    Conclusions:

    • Disabled individuals can perform sustained proofreading tasks effectively for extended periods.
    • The study demonstrates the viability of employing individuals with diverse disabilities in data processing roles requiring proofreading.
    • Findings suggest that error density may not negatively impact sustained attention in this context, supporting workplace inclusivity.
