Feedback during a trial

Roland

Hi,

I'm working on a dot probe task and I want to give a "feedback reminder" during a trial when participants are a bit slow and could go faster. I want the reminder on screen while a trial is still in process and is still going to be completed.

When participants have to give a keyboard response, I want to show a "Go Faster!" reminder on screen if no response was given after 500ms, the "Go Faster!" message should fade away after 300 ms. During this time, participants should at all times still be able to give a keyboard response

This is how it should look like during the trial. Can't figure out how to do this.

Thanks

Hi @Roland ,

You could do this by using a coroutines item and presenting one sketchpad (without the reminder) at 0 ms, and then another sketchpad (with the reminder) at 500 ms. A keyboard_response would then be running all the while, from the beginning to the end of the coroutines . Like so:

Hope this helps!
