Displaying an equals sign
Displaying an equals sign
[edited from support email]
I'm having a problem using "~=" as stim. It seems not to be displaying. I tried replacing the "=" with the word "equals", leaving everything else the same, and it worked fine. Do you know if there is an issue with using "=" as stim?
I think that is occurring because ~= is used in cases where you want to set a text stimulus to be equal to the response from a previous trial (see Using a Subject's Response as a Stimulus in the section on Input Files > Stimulus in the user's guide for details). I haven't encountered this before, i.e., where one would present a single equals sign as a text stimulus. Since DirectRT is apparently having trouble understanding this, you can try inserting a space before (and after if centering) the equals like this:
~ =
I just tried it and it seemed to work ok.
