jump or if then?

[jotapan]

Hi Michiel,

Thank you so much for your reply and for the link to your e-prime
guide. It will be very helpful!

I have been able to jump task 2 when participants responds B in task 1
using your suggestion, but I now have a problem in the response and RT
data logging. I was expecting the program not to save any information
for the task2 trials when they are not presented to the participant
(i.e., when it just jumps to task 1 again not presenting task2).
However, the program is simply repeating whatever response is given
the first time task 2 is presented on the following trials when task 2
is not presented; these data only change the next time task 2 is
presented again and another response is given to the task.

In this case, you would be right - and if the getting started guide may not do it for you, I'd suggest working through our little bit of freely available course material (www.cognitology.eu, about me, underneath everything else), because, ultimately, you cannot use E-Prime 'instantly' (at least, very few students seem to, even though there are some talented 'coders-to-be'). So, despite me answering this question, try to give it a go anyway.
