Dear all,
it's my first time working with online-testing. I've collected 86 participants so far which leaves me 6192 trials. In 956 trials (appr. 15%) no reaction was logged thus the trial timed out (STATUS = 3). This is extremely unusual & I'm currently trying to figure out why that might be the case.
I just caught a mistake I made in the scripting and I'm wondering if that could have anything to with this high number of errors of omission:
In the line "readkey @5 4000" the allocation of the "correct column" is incorrect, it should be "@8" instead of "@5". Column 5 in my case was a line of string, so PsyToolKit didn't have any number to compare to the number key that was supposed to be pressed but instead it was comparing it to a string. (While this of course makes all the STATUS entries incorrect, that is something I can re-code since I had the experiment save the KEY and which key would have been the correct one. )
What I'm wondering is if that could have messed with the logged RT in any way? Like because PsyToolKit was trying to match a number key in KEY with a string from the wrong correct-column, did that result in so many errors of omission?
I really hope for some helpful advice & insight.
Thank you so much
Denise
