Hello there,
we run an experiment at the moment where we use a 2-back task with a set of 8 circles. However, some participants report that the goal stimuli are not shown. Instead there is just the neutral stimulus appearing over the whole time of the experiment. By a short flash during the presentation you can tell it is renewed with every trial. Record data shows that the keyboard input is still detected, but without influence.
I have the feeling it particularly appears on older computers, but I am not sure...
What could cause this problem?
Thanks for your help.
