Express is a web-based technology that simplifies running experiments with multiple participants or computational models across different computers. It automates client coordination and data collation, balancing groups and merging results efficiently.

Area of Science:

  • Cognitive Psychology
  • Computational Modeling
  • Web-based Technology

Background:

  • Traditional experiment presentation packages offer limited support for distributed computing.
  • Researchers face challenges in balancing groups and merging data from multiple computers.
  • Evaluating parameterized computational models across various parameter values is computationally intensive.

Purpose of the Study:

  • To introduce Express, a novel web-based technology for coordinating distributed experiments.
  • To address the limitations of existing software in managing multi-computer experimental setups.
  • To facilitate the efficient evaluation of computational models using parallel processing.

Main Methods:

  • Development of Express, a web-based platform for experiment coordination.
