Pupil size data analysis
I hope this is the right forum for this question. I'm currently a linguistics student helping out in a larger eye-tracking project (link to OSF page) that is currently running. For my thesis I've collected pupil size data in monolingual and bilingual infants during a replication of Kovács and Mehler (2009) with a Tobii T120 and Pygaze to run the experiment. I want to analyze pupil size across time for each trial/block and compare the two groups. Fun idea, but I have no clue how to actually go about this. I only have a very basic understanding of R and don't know how to clean up/analyze eye-tracking data in there, or whether another program would be better for this.
I hope someone could give me pointers in the right direction. Is there a Dummies guide to processing and analysing pupil size data that I don't know about? Should I use R or is there a better program for this? Where do I even start?
Sorry for the newbie questions! If more details are needed, please let me know.
