Group: Forum Members Posts: 14, Visits: 66	Hi there, I am wondering if there is a way to set a minimum response latency in an IAT. I have been able to get output indicating responses below a certain latency. Is there a way to make it so if participants try to move forward too quickly, a message appears telling them they are going too fast and requires them to take a certain amount of time to respond? Thanks!

Thanks! Generally short response times (< 300ms) are permissible in IATs, as long as there isn't an excessive amount of such short response times. What you could do fairly easily is /branch to reminder <trial> that alerts participants to slow down in case latency in a given trial falls below some threshold.

What you could do fairly easily is /branch to reminder <trial> that alerts participants to slow down in case latency in a given trial falls below some threshold. Basic example attached. Take a look at the /branch attributes in the attribute and target trials, the added <trial toofast> element, and the changes to the combined blocks' /ontrialend logic.
