Classperiment: a free tool for live cognitive psychology experiments in lectures
Classperiment lets students experience classic paradigms in the lecture hall instead of only hearing about them. Students join with a QR code on their own phone, tablet or laptop, without an app or account, and complete a task such as Stroop, flanker, n-back, visual search, attentional blink or mental rotation. Directly afterwards the projector shows the class means with confidence intervals, so the group can discuss its own data. 33 paradigms from attention, cognitive control, working memory and perception are available in English and German. Raw trial data stays on the students' devices; only summaries without names are submitted, and only if students agree to share them. The tool is developed at Ulm University and is currently in beta. Feedback from instructors on how it works in their courses, and on which paradigms are missing, is very welcome.
