Data

Contact Peter Jurica if you are interested in collaboration or the data.

The data for this experiment have been collected on the SRI Eyelink I, see EyeLinkInfo page for more information. Data from 23 subjects were collected, see the subject summary page for details.

In total at least data from 6 sessions were recorded for each subject. There were 4 different types of sessions. All types of sessions had one common set of instructions, which was:

1. keep eyes on either the cross or the target, whichever is present until it disappears,
2. move your eyes as quickly as possible to the target or cross when it appears on the screen.

The types of experiments were the following, click on the link for more details:

To assure that the subject understands and obeys the instructions two practice sessions were coducted before the real experiment sessions started. The first practice session was of the Surface1type and then the Surface5 type session followed. Each practice session consisted of 2 blocks with 15 trials. All the experiments are described in details in the method section of this site.

For the purpose of analysis the data collected were converted into text files with the contents relevant to the analysis stored in tabular structure. Certain steps had to be taken to correct the recorded data and all of them are documented on the DataRepair page.

After all the files had the correct format a conversion was to simple tabular structure was performed. The format of the data ready for analysis is decribed here.

Software

Most of the analysis so far has been done using MATLAB or Python programs. You can have a look at the SurfaceToolbox project page. The surface toolbox is a compilation of functions that I am using for analysis of the eye movements.
