💡 How can researchers build sustainable business models to support open research tools?

Join us tomorrow at APS 2025 for our talk:

🗓️ Friday, May 23
🕛 12:00–12:15 PM
📍 Dupont Room

We’ll share the tools we've developed and how we sustain them.

Are you at #APS this week in Washington?!

We are too! Come see us at booth 204!

We will be right here 👇

Using code for experiments and stimuli is a great visual way to learn.

I learned the majority of python from experiment design.

"How do I auto-counterbalance automatically in PsychoPy?!"

Here’s a walkthrough of the Counterbalance component!
We hope that you enjoy!

What do you mean? Of course I’m not spending my Friday night nerding out with Edwin Dalmaijer and @hirstrj.bsky.social and @peircej.bsky.social

Regarding newer mac models, PsychoPy with PTB 3.0.19 does run fine on ARM-based macs in Rosetta mode and so far PTB has been the main limiting factor preventing us switch. But again, it would mean requiring users to pay the license fee which I think most will be looking to avoid

PsychoPy uses PTB as an option for keyboard input and audio in/output. No other part of PTB is code is used
For now we'll continue to ship PTB 3.0.19 ("Last free lunch") within PsychoPy Standalone. We'll be looking at 3.0.20 as an option for users with a PTB license

Psych-DS is (1) spellcheck for your datasets and (2) a pathway to standardizing data in our academic fields that *everyone* can learn.

And it's live RIGHT NOW!

Open Science Tools team day !

🌞And what weather we had for it for a wander around @uniofnottingham.bsky.social !

Why is a day working in the same room so nice and productive?

Pavlovia The place for the wide community of researchers in the behavioural sciences to run, share, and explore experiments online

PsychoPy includes Stroop built-in and Eriksen flanker tasks are readily available. You can either get students to install the PsychoPy app to build/edit tasks themselves, or you could just point to online versions of tasks on pavlovia.org if you just want them to *run* the study

I'm really looking forward to SPSP in Denver. It's my first time attending and very excited about the cool stuff we're going to hear.

Make sure you stop by the PsychoPy (Opens Science Tools) booth of you're there so we can chat about what you do

New webcam based eye tracking demos!👀

You can use js packages in your Pavlovia experiment, including webgazer.js

You can also update stimuli frame-by-frame based on gaze 🧐

This demo measures dwell times on faces..

That feeling when you realise your bike has a puncture... and you're still 2 miles from work 😒

Thanks. I've joined that although Gemini/chatgpt are currently helping me convert bash/zsh into PS (with a few bits of false info just to keep me on my toes)

🎥 Did you know that you can present YouTube videos in your Pavlovia Survey?🎥

Use an "Image" question type and use "YouTube" content mode.

OR

Use "html" question type and provide the html for an iframe.

Take a look at the demo here https://buff.ly/3WrSSj4

It turns out that
- installing bash on windows, and getting GH Actions to recognise it, was hard
- setting up pwsh on mac/linux is easy

So now I'm embracing powershell and finding that, although it's a weird syntax at first, I'm actually starting to like it!! 😳😉

Will see if it lasts!

I use private runners and I want my GitHub actions workflows to run the same code on all platforms (rather than write each step multiple times) so I want 1 shell that works with all platforms on my private runners

[just for GitHub Actions peeps]
I'm shocked to find myself thinking about switching to powershell for cross-platform devops scripts!!

Delay discounting (with fixed delay) is a simple demo to get started (adaptive methods are possible).
