jump or if then?
jotapan
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

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,

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.

It shouldn't, as far as I can see. Do you have the most typical E-Prime structure here, or are you, in fact, jumping to and fro, indeed adding even another goto to my suggestion? That is to say, for E-Prime, it makes sense to stop thinking about "go to task 1, then goto task 2, followed by task 1" but instead see it as:
In the beginning, there is a trial.
In one trial, we present either one or two stimuli (or tasks, if you will).
This means that there is no "going back to task 1" but rather, at the end of the trial, the procedure is repeated. In which case, Stimulus1.RESP as well as Stimulus2.RESP should be cleared.
If this shot in the dark totally misses, however, you can just ignore me and use some work-around. I like to store my dependent variables as "Y_" followed by the type - so they all are stored at the end of your .edat file. This also gives you a little bit of flexibility in storing your data as you would like to analyse it. I'd say pick the correct lines and store your favourite responses at your favourite moment by doing something like
c.SetAttrib "Y_RESP2", Stimulus2.RESP
or, which shouldn't be necessary, at the very end:
IF Stimulus1.RESP = "a" then c.SetAttrib "Y_RESP2", Stimulus2.RESP else c.SetAttrib "Y_RESP2", ""

Thank you so much for this new input. I think I have the right
structure in my procedure. Here is what I have in my procedure:
> Slide 1 : allowed responses a & b
> InLIne: If slide1.RESP="b" THEN goto donttask2
> Slide 2: allowed responses 1, 2, & 3
> Label: donttask2
Indeed at the end of this sequence it moves on to the next trial on
the list. Am I missing something?
I'll try you suggestion as well,
Best,
Jotapan

Thanks for your new suggestion.
I think I'm using the right structure, but I might be missing
something :(
Here's what I'm doing in this procedure:
> Slide 1 : allowed responses A & B
> InLIne 1: If slide1.RESP="b" THEN goto donttask2
> Slide 2: allowed responses 1 & 2 & 3
> Label: donttask2
I'll be trying your suggestion,

here. But as an academic exercise, here is how
to accomplish the same thing using Jump and no inline.
Trial proc structured same as before, but no inline:
- Slide 1 : allowed responses A & B
- Slide 2: allowed responses 1 & 2 & 3
- Label: donttask2
On Slide 1, set Jump Label to donttask2. Then
add *two* keyboard input masks. For one of them,
set Allowable to A, and End Action to Jump; for
the other, set Allowable to B and End Action to
(terminate). That should do it.
Using multiple input masks and Jump is an art
suitable to only a few, most will find If-Then in an inline more manageable.

In an example like this, how do you make the program jump if the participant doesn't reply in the given time?
So, let's say you have slide A followed by slide B. But slide B only appears if a specific response is given on slide A (for example "B"). If another response is given on slide A (let's say "A"), then the program jumps (using a Label) to the next part of the procedure. What if i want the program to go to do that same jump (so, we're skipping slide B) if participants don't respond in the given time to slide A?
Thanks in advance
