Dear all,
I am building an experiment working from the example script that implements the custom VAS that is available via the download library. The issue that I am running into is that the script at present only allows one response. That is, a participant can indicate his/her response on the line of the VAS only once and then the script automatically continues to the next item.
Although a paper-based VAS works in this way as well, it still is possible to correct the initial response. A computerized solution using a <slider> also enables this, but for various other reasons I would like to refrain from using a slider.
I have progressed to knowing that the problem/challenge is within <trial VAS> and <trial showresponse> (see below), but I haven't been able to find a solution (or even a kludge) to make sure that a participant can correct the initial response. The full script (so far) is attached.
Thanks for any pointer that my help me on my way!
Best, Paul
