Is there a way to make a polygon stimulus thinner?

Coding
1

Hello,

I am hoping to generate a cross polygon that appears as a thin cross. I have attempted to change the width of the stimulus in builder, but it seems as though there is some sort of threshold where it won’t shrink the width past a certain point.

I imagine that if there is a solution, it would have to be done through coding. How would I accomplish this? I have no idea where to start.

Thank you!

You could use two line stimuli or a custom polygon with suitable vertices.

Here’s an example to get you started. Make the .25 values smaller to make a thinner cross.

[[1,.25],[1,-.25],[.25,-.25],[.25,-1],[-.25,-1],[-.25,-.25],[-1,-.25],[-1,.25],[-.25,.25],[-.25,1],[.25,1],[.25,.25]]
