[visionlist] Free browser tool for live perception and attention demos in lectures (beta)

[Marian Sauter]

Dear colleagues,

(apologies for cross-posting)

I would like to share a teaching tool I have been developing at Ulm 
University: Classperiment, 
https://classperiment.com/teach?utm_source=visionlist

It lets you run classic experiments as live demonstrations in a lecture. 
Students join with a QR code or session code on their own phone, tablet 
or laptop, with no app and no account, and complete the task in the 
browser. Right afterwards the projector shows the class results: 
condition means with 95% confidence intervals and the distribution. Each 
student also sees their own result next to the class result. Most tasks 
take between half a minute and three minutes.

33 paradigms are available, including visual search and pop-out, 
attentional blink, change detection, random-dot motion, signal 
detection, Posner cueing, inhibition of return, Navon figures, mental 
rotation and the Müller-Lyer illusion. The interface is available in 
English and German, and results can be exported as CSV.

Raw trial data stays on the students' devices; only a summary without 
names is submitted, and only if the student agrees to share it. 
Classperiment is meant for classroom demonstrations, not for lab-grade 
timing.

You can try every task yourself without signing up:

The site is in beta, and I would be grateful for feedback from people 
who teach these topics: does it work in your lecture hall, is anything 
unclear, and which paradigms are missing? Replies to me directly are 
very welcome (marian.sauter at uni-ulm.de).

Best regards,
Marian
