js-mEye: An extension and plugin for the measurement of pupil size in the online platform jsPsych The measurement of pupil size has become a topic of interest in psychology research over the past two decades due to its sensitivity to psychological processes such as arousal or cognitive load. However, pupil measurements have been limited by the necessity to conduct experiments in laboratory settings using high-quality and costly equipment. The current article describes the development and use of a jsPsych plugin and extension that incorporates an existing software that estimates pupil size using consumer-grade hardware, such as a webcam. We validated this new program (js-mEye) across two separate studies, which each manipulated screen luminance and color using a novel luminance task, as well as different levels of cognitive load using the N-back and the Stroop tasks. Changes in luminance and color produced significant changes in pupil size in the hypothesized direction. Changes in cognitive load induced in the N-back and Stroop tasks produced less clear findings; however, these findings were explained to some extent when participant engagement – indexed by task performance – was controlled for. Most importantly, all data were at least moderately correlated with data simultaneously recorded using an EyeLink 1000, suggesting that mEye was able to effectively substitute for a gold-standard eye-tracking device. This work presents an exciting future direction for pupillometry and, with further validation, may present a platform for measuring pupil size in online research studies, as well as in laboratory-based experiments that require minimal equipment.

It's the second Tuesday of the month, which means I'm doing drop-in office hours for #jspsych support on our discord. 10:30-11:30 EDT.

discord.gg/RCKWJ4qb3p

Supervising a Psychology student creating an online #mousetracking experiment with #jsPsych - showing videos and asking participants to choose left or right.

If you’ve worked on something similar and are happy to share a code template or know of good resources, we’d really appreciate it! 🙂

We've just
launched a Discord server for #jsPsych users to collaborate and get technical help.

I'll be hosting office hours tomorrow from 10:30-11:30 AM EDT. Hop in with any questions!

We are running a virtual hackathon for #hacktober! Info and signup here: jspsych.github.io/hackathon/virtual_2025.html

We will be hosting drop in office hours help during the hackathon, so this is a great chance to level up your jspsych skills!

This uses WebGazer + jsPsych to test the viability of online eye tracking in five case studies.

Very cool to have been involved with this, such a great opportunity to learn about contributing to open source software! ⌨️

We will be doing this again next spring. If you want to keep up to date on this and other events you can subscribe to our newsletter: www.jspsych.org/latest/newsl...

That's a wrap on our first ever hackathon! Thanks to all of the wonderful people who attended. Lots of amazing projects and collaborations got started. 🥳

At Grand Central in NYC on the last leg of my Seattle WA -> Poughkeepsie NY trip to attend the @jspsych.org hackathon. Exciting!!!

I'd love to hear what you think we should be working on. What is jsPsych missing? What are the pain points?

jspsych will soon* support generating psych-ds metadata automatically from an experiment timeline. we have done most of the implementation and are ironing out the final details.

*probably summer 2025

We're hosting a hackathon in May! This is aimed at jsPsych users who want to learn how to contribute to open source software and extend jsPsych. It's free, and we'll cover travel expenses. Learn more and sign up here:

jsPsych Plugin: Visual Pattern Task - Stoo Sepp After learning jsPsych in December of 2024, I built a VPT (Visual Pattern Task) plugin for use in psychology experiements. This task by Della Salla et al. (1999), and used by Chu et al. (2013) with a ...

If anyone needs a Visual Pattern Task (VPT) for jsPsych experiments, I have a work-in-progress. Feel free to try it out and reach out if you need more customisations or data out of it. #research #jspsych #workingmemory
