-In the task, the stimuli could have either been the same or different (after rotation). same/dif recorded that.

-The next column specified whether the rotation was right or left. This probably wouldn't impact performance.

The sets of 01s are a recoding of the actual matrix that was presented, in row order, both initially and as a test.

The next two are times. The first is study time (the task is self-paced), and the next is response time.

The final two columns indicate the response key pressed and whether they were correct. You'd have to check the experiment to determine whether right mapped onto same or different.
