jump or if then?

[Michiel Spape]

Hiya,
If it's as simple as you think it is, you should be able to do it after having read the "getting started guide". 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.

1. Stimulus1 is a textdisplay saying "Do you want to do task 2? A = yes, B = no", allowable response ab. That's just about what you want, no?
2. After that is an inline saying
IF Stimulus1.RESP = "b" THEN goto Dontwanttodotask2
3. Stimulus2 is a textdisplay saying "Select response 1, 2 or 3" (or whatever you'd like).
4. Then insert a label, call it Dontwanttodotask2

That's basically it. Note that I use no else, since Stimulus2 will follow anyway, unless b is selected. After 4 is the end of the trial, so it should continue with your task1.
Best,
Mich

Subject: jump or if then?

Hi to all,
I have what I believe o be a simple task to program, but I just not
being able to do it since I'm a beginner in e-prime.

I have two tasks:
1) task 1: responses A and B
2) and task 2: responses 1, 2, and 3

I want task 2 to be presented to the participant only if he responds A
in task 1; if he responds B he should just gets the next trial of task
1.
I tried looking into the "jump" of the stimulus property, but from
what I understood it works independently of what response is given to
that stimulus.
Another idea I had was just to create a script with an if then rule,
which I don't know how to do :( the idea would be something like (with
proper coding)

If response to task 1 = A,
then task B,
else Task A
end if

Any help would be very appreciated! thanks
Jotapan
