eye tracking data analysis

#1
Hi, I am working on a project using eye tracking to investigate code switching with the visual world paradigm. I want to compare how long it takes for participants to fixate to target 80% of the time and how it varies between Spanish and English trials. I want the how long it takes to reach 80%fixation to be my DV, but I don't know how to calculate that.

You use terms such as "code switching" and "visual world paradigm".
So there are certainly methodological standards for the definition of
reaching 80% fixation in your reference literature?

Or does your question aim at something else?

With kind regards

Hi, thank you for responding. For visual world paradigm, yes. Basically I am showing 4 images on the screen and I want to determine when an observer is fixating on one of them 80% of the time. Code switching means there are two language type of trials and I want to compare whether one language type of trial reaches 80% fixations faster than the other. I hope this makes sense!

So you do not need to know how to calculate the time until 80% fixation is reached,
but how to compare the two conditions?

How large is your sample size, and does each participant complete each language type
of trial, or are there 2 distinct groups of people?

With kind regards
