I’m trying to conduct a study in the field of cognitive experimental psychiatry. I need an online tool on a PC-based setup to administer Stroop, N-back, and choice reaction time tests. I found Psytoolkit an open-source tool than has Stroop and N-back and it is programmable. But I’m not sure whether this tool is validated or not. By validation, I mean whether N-back test measures working memory (as it is supposed to) or not when running the test on Psytoolkit.
I’m looking for validated online cognitive tests if anyone knows. Thanks.
