Some of our studies involve online web-based experiments. Here is a demo of the 'optimal reminders' task.
Variants of this task were used in the following article:
Gilbert, S.J., Bird, A., Carpenter, J., Fleming, S.M., Sachdeva, C., & Tsai, P.C. (2020). Optimal use of reminders: Metacognition, effort, and cognitive offloading. Journal of Experimental Psychology: General, 149
More demos coming soon...
