Hello,I'm a French student user of inquisit since 2 years, I'm trying to do a simple IAT test. As it's for people with cognitive disabilities I want it to show an error message
if the response latency go over 1500ms. I've tried with /ontrialend = if(trial.mytrial.latency >=1500) trial.mytrial.error =true). Nothing happen, and I can see another way to do
it, if someone could share an idea ?
