I’m writing an experiment on the effects of a background flash on Inhibition of Return.
To do this, I have two Picture File Events in succession:
Slide 1 (250ms)
Slide 2 (4750ms)
These are the final events in the trial.
I need there to be a participant response functional for both slides, in case the participant responds quicker than 250ms.
If the participant responds during the first slide, I do not want the second slide to be presented.
To do this, I have added a Feedback to Slide 1:
Provide Feedback If:
Reaction time is less than 250ms
What to do:
Skip remaining events and present next trial
However, it doesn’t work: if my reaction time is less than 250ms (i.e., I respond during Slide 1) it collects the data that I want, but then not only does it not skip Slide 2, but sometimes it will even make it so that Slide 2 doesn’t end after a participant response (I have for Input checked “end after participant response” and “end after time limit”).
If I’m going about it wrong, how can I achieve the same effect through different means?
