I’m trying to build an experiment in which the subjects will listen to and answer 200 questions while fixating their gazes on an image displayed by a computer screen, and their pupil diameters will be measured continuously by ASL through out the experiment. I’m using Measurement Computing PCI-DIO24 to send digital signal from Superlab to the ASL system.
This is what I need and I couldn’t figure out a good way to do it:
- An fixation image is displayed through out the experiment.
- Markers at the beginning and the end of each audio sentence;
3, A marker for each response (I’m using RB-530 keypad);
- Sentences are randomized for each subject.
Thanks for the help in advance!
