My team and I, we collected data from about 40 children (age 6 years - 12 years) in a study where we tested the children on two measures. 1 was an executive functioning task called Happy and Sad task (adapted from Kristin Hansen Lagattuta , Liat Sayfan, and Michael Monsour) - and second being the concept of knowledge behavior gap in resource sharing in two different Dictators Game Scenario. We used this website called lab.js.org to design and execute the experiments.
It went very smooth for us.
Thanks so much, I hadn't seen this, and have now submitted my EoI!
