Jumping/Gating

[sga...@macalester.edu]

Hello,

Our research team is new to E-Prime, and we have run into a problem. Our experimental paradigms require what E-Prime seems to call jumping (i.e., leading the participant to encounter different stimuli depending on his/her response to initial stimuli). Prior to our travails with E-Prime, we knew this process as "gating." After reading up on Jumping on this forum and in various manuals. it seems that this procedure requires the use of a Label (and/or Jump Label) and some manipulation of the "End Action" component of a stimuli's properties. However, neither our Principal Investigator nor anyone else in the lab can determine how to make this happen. I am beginning to think it might be easiest with some InLine code writing, but I could be incorrect because none of us really know what we're doing.  If anyone can explain how this works, it would be much appreciated.

Hi,
This is not too complicated:
Lets say you have 3 slides and you want to skip to the third slide if the answer on the first one was "3". You put a label flag before the third slide, and inline after the first one says:
If slide1.resp=3 then goto/jump to label1

You can also use slide1.acc if you want to jump fot correct or incorrect answer.

This is the basic idea.
Good luck!

Hi,

I realize that this is an old post, but I am having the same problem. I am assuming that the inline code is a bit more complicated than 

"If TextDisplay1.resp=2 then goto Label1"

I tried using this text and I got the error message "Type mismatch"

Any advice or more specific code to use?

Thank you!!!

Have you managed to figure this out? I have a simillar issue: with a code line like that (using either .RESP or .ACC) it always skips slide 2 for me.

Just to answer the question from Tina on 20 Dec 2013 ...

.RESP returns a string value, so you need to compare it to another
string value instead of to a numeric value, otherwise you get the "Type
mismatch" error at run time. So the proper line of code would go

If (TextDisplay1.RESP = "2") Then Goto Label1

Note the added quote marks (I also added some parentheses for clarity,
etc.).
