Analyze eyetracking data using MATLAB working with structure arrays

Closed Posted 5 years ago Paid on delivery

Our aim is to analyze whether there are differences in a measurement (change in pupil size) between two groups of subjects. We have 6 subjects in one group, and 9 in the other.

The data that I will give you is stored in a structure array. (see the attached file called "our structure array") There are different fields in this array as you see. One of them is called "Events".

If you go to [login to view URL], you will see some messages, like "ValidTarget" or "FB_Hit" etc. We want to know whether the pupil size increases or decreases after ValidTarget and some other messages. You can find the specific time point that an event happened, and then check the pupil size at that specific time point using DATA.Samples.PupilSize. (see data overview [login to view URL] that I attached) We can also look at changes across different conditions that I can explain later.

There are also pre-processing steps needed. These may be: 1) remove eyeblinks 2)interpolate 3)Baseline correction 4)Normalization 5)Down sampling. 6)Rejection (reject data with more than 20% of loss and those with outliers (pupil measurements > 2 standard deviation).

I will give you some sample code which will be helpful but not adequate. I will always be available to answer technical or instructional questions that you have. I will also give you more info about instructions later. Note: You will have to share the code that you generate with me.

I think the analysis will be more fun and less overwhelming than it sounds. :)

Please let me know if you have any questions. Thanks!
