We developed a novel computational method to generate diverse cognitive assessment trials, inspired by game design. This approach, using procedural content generation (PCG), creates scalable and adaptable tasks for cognitive research.

Area of Science:

  • Cognitive Science
  • Computational Psychology
  • Human-Computer Interaction

Background:

  • Cognitive assessments require diverse trials for robust evaluation.
  • Traditional methods for trial generation can be time-consuming and lack scalability.
  • Procedural content generation (PCG) offers a potential solution for automated content creation.

Purpose of the Study:

  • To introduce a computational approach for generating new cognitive assessment trials.
  • To demonstrate this methodology using a novel executive functioning planning task.
  • To provide guidelines for digital cognitive task development and procedural trial generation.

Main Methods:

  • Developed a scalable and adaptable method for generating experimental trials, inspired by PCG in gaming.

  • Created an executive functioning planning task involving block matching, assessing planning abilities.
  • Employed a generate-and-test methodology: pseudo-random puzzle creation followed by a solving algorithm to ensure solvability.

    • Main Results:

    • The procedural generation technique successfully produced a large number of diverse and solvable trials for the planning task.
    • The developed task is accessible online and has undergone usability and functional testing.
    • The approach demonstrates the feasibility of using PCG for creating varied cognitive assessment content.

    Conclusions:

    • PCG is a promising technique for the scalable and automated generation of high-quality cognitive assessment trials.
    • Future work should explore advanced algorithms for optimizing trial generation and psychometric validation.
    • Guidelines are provided to facilitate the development of digital cognitive tasks and PCG for various research applications.
