URL of experiment: https://run.pavlovia.org/Drifters-escape/implicit-association-test/html Description of the problem: Hi, I have a problem with the presentation of stimuli in an implicit association test. As shown in the attached image, the text “NaN” is on top of the presented picture. It does th…

I think this is just the text_stim component of the trial not being set to anything. You should be able to either turn it off in the builder or add it to whatever is controlling the loop with the text ‘’, which should render as blank.

Would it be alright to ask for an explanation on how to turn off the text_stim component of the trial on the builder? I’ve been running into the OP’s problem as well. Thank you for your help! @drifters-escape were you able to figure out the issue?

The easiest way is probably to click on it and then go to the “testing” tab and check “disable component”. Or just right-click on it and hit “remove”.

Thanks for your input, but the text_stim component needs to be enabled in the trial because the point of the test is to present affective words and concepts interchangeably. So if the text component is disabled, it will only be a black screen when the word is supposed to be displayed. As I mentione…

That’s all Python code, which isn’t all that helpful for figuring out the behavior online. Do you have a link to your pavlovia repository? Be sure to make it public (settings -> permissions). It’s almost certainly an issue of the conditions file, but I need a closer look at the actual code to be su…

Ahh… I’m pretty new to this. Here is the pavlovia repository: https://gitlab.pavlovia.org/Drifters-escape/implicit Here is a link to the test if you want to try it out: https://pavlovia.org/run/Drifters-escape/implicit/html/ Thanks alot!

I fiddled around with the code with some friends (who were CS majors) last night, and we were able to remove the text! What we did was insert text_stim.setText(“”) right under the line of code reading currentLoop = trials

@drifters_escape your best bet is probably to put a blank space or the text “” in the cells where there is no text stim.

I found that a space character worked in PsychoPy, while an empty cell worked in PsychoJS. To be clear, I was assigning a variable read from my Excel conditions file to the text field of a text component and I wanted the text to show up as blank when there was no value in the cell of the conditions …

Hi, I have a similar problem in which I’m trying to pull an empty text from the excel condition file. In Pavlovia I get “NaN” instead of nothing… When there is text, it works well. Does anyone have a solution for this? https://pavlovia.org/Weinbach/iat_weight_o1

You could use the solution I present here (which I used in my edition of public-iat): "NaN" appears when using spacebar to denote empty cell in pavlovia - #18 by wakecarter
