Nik, I've updated the simon task wiki page to discuss the data output, and some other aspects of the task:
http://pebl.sourceforge.net/wiki/index.php/Simon_Task In brief, columns refer to: subnum: participant code trial: ordinal counter for trial type: stimulus type (leftcolor versus rightcolor) pos: position from center. This relates to Yamaguchi and Proctor's finding that distance from center impacts interference. resp: the response that was made (left or right shift) corr: whether the response was correct time: absolute time counter, in ms, of the trial completion rt: response time, in ms Compatible trials will be type 1 with negative pos, and type 2 with positive pos; incompatible will be the reverse.
