Re: How to set keyboard press as a trigger?

[McFarlane, David]

Trying to follow this ...

So most of the time the subject gets n-back trials. Then every once in a while the subject gets a cue word instead of an n-back trial. When that happens they must press SPACE. After pressing SPACE the task pauses for 20 s and then resumes with, I suppose, the next n-back trial.

Do I understand this correctly? What do you want the program to do during the 20 seconds? Maybe show us a concrete example of what how you want this task to flow.

In this task, participants will perform the n-back task as a secondary task, therefore when congruent stimuli will be presented, participants should react by pressing the specified button. However, I want to set another button ("SPACE") for the primary task. So when participants will performing the n back task, they will have to press "SPACE" button following the cue word presentation. After pressing "SPACE" button, a timer will start and after 20 seconds, the next slide will be shown. I also want to record reaction time when they press the "SPACE" button.
