Hello, I successfully built my dot-probe task in builder view (without the use of code). However, I am struggling with randomizing the incongruent and congruent trials. For example, shape, figure, and physique will always be congruent (i.e., the dot-probe will always appear behind these words) whe…

[image] Dot probe on psychopy builder, how to select a picture randomly from a folder to present on each side of the screen? Builder What you need is independent randomisation. Have a look at my demo.

Hey I am struggling with dot probe task on psychopy as well. But I achieved it on psychtoolbox with matlab. You can put all your neutral stimuli and biased stimuli into two different matrixes, then selecting one from each matrix randomly to present in pairs. I’m thinking how to make it work with pyt…

Hi again! I attempted to create code from your demo, but without knowing ANYTHING about code I am a bit lost. I attempted using code, but I keep getting an error message “setting an array element with a sequence.” As a reminder, I am trying to use independent randomization in a dot probe task. Spe…

In your component you are using orientation (your list) rather than your chosen orientation? Possibly similar with position

Thank you for your response, I fixed the error message “setting an array element with a sequence” by inputting this into the builder view; [Screen Shot 2021-07-15 at 8.18.52 AM] However, I now get both words overlapping and the dot probe always on the left side OR in some trials I get everythin…

randint(0,1) is always 0 I think. Personally I always put that kind of code in a code component, so it can work online too.

You mean in builder view? [Screen Shot 2021-07-15 at 8.38.52 AM] error message; [Screen Shot 2021-07-15 at 8.39.08 AM] but if I put; [Screen Shot 2021-07-15 at 8.40.28 AM] it works but every 2nd word pair becomes overlapped… is there a way to fix this?

What combinations of values are overlapping?

not too sure if I understand the question… but my word pairs, which are constant (slim is always paired with cheer) are overlapping. For example, the first word pair (slim/cheer) is effectively presented on the left and right. then my second word pair (thin/glee) is overlapped (both are being presen…

The issue is, I think, that you are generating a new random number for each location instead of generating one number and using 1- that value for the other location.
