Seeking Alternatives to jsPsych for Conducting Online Behavioral and Cognitive Experiments

Experiment Design

In the world of psychological research, jsPsych has proven to be a valuable tool for designing and running online experiments, specifically in the areas of behavioral experiments and cognitive tasks. However, as remote studies become the norm, some limitations have arisen that may require alternative software development platforms. This article will detail such constraints, list alternatives to jsPsych, and discuss how to migrate as well as the costs involved.

Current Limitations of jsPsych

jsPsych is a robust, flexible, and widely used library for psychological research. However, it's not without its shortcomings. Some limitations include:

  • Limited scalability: Large-scale studies might encounter performance issues.
  • Technical know-how: Proficiency in JavaScript is necessary, which can be a barrier for researchers without a coding background.
  • Less support for mobile devices: While jsPsych supports desktop browsers very well, optimization for mobile devices is limited.

Alternative Platforms to jsPsych

Many online platforms offer similar capabilities to jsPsych and can accommodate for its limitations. Here are some examples:

  • Cognition: A no-code platform for creating and running experiments across multiple disciplines, including psychophysics, neuroeconomics, and cognitive psychology. An airtight platform, it is both beginner-friendly and mobile-optimized.
  • Pavlovia: A platform that supports online data collection in an array of languages, including Python and R. It also offers participant recruitment services.
  • Gorilla: A rich, user-friendly environment that's great for designing complex cognitive tasks without the need for extensive coding skills. It also performs well on mobile devices.

Migrating from jsPsych to Alternative Platforms

Migration from jsPsych to an alternative platform involves several considerations. Firstly, researchers need to assess how much of their current experiment design can be recycled. Platforms like Cognition allow researchers to create studies using intuitive drag-and-drop interfaces, which can make the migration process smoother. However, each platform will have different interfaces, limitations, and capabilities for specific cognitive tasks, thus understanding these specifics are crucial.

Considering Cost in Migration

When it comes to cost, most online experiment platforms operate on a subscription-based model. This means that switching from jsPsych, a free library, will likely incur ongoing costs. The long-term benefits such as user-friendliness, mobile optimization, and scalability should be considered against these ongoing costs.

In conclusion, while jsPsych has been instrumental in the development of online experiments, its limitations make alternatives like Cognition , Pavlovia, and Gorilla worth considering. While migrating may pose challenges, the potential benefits for behavioral and cognitive experiment researchers might just make the switch worthwhile.
