Jessica, Be sure to look at the wiki pages for each of the tests for information about interpreting the data: http://pebl.sourceforge.net/wiki/index.php/PEBL_Test_Battery I can't really tell you what variables you need to focus on--that depends on your hypotheses. In the past, for TOL, people usually look at number of moves or number of extra moves; as well as time-to-first move. Not all of the versions provide all of these. For stroop, people usually look at differences in mean response time between interference, congruence, and neutral conditions. For corsi blocks, one often uses the longest length that is recalled correctly at least 1/2 times. For the switcher task, you should probably look at time to complete each round (or average time per click), comparing the different switch conditions. Also, errors in that task are usually intrusions, and so you could count intrusion errors. Best, Shane > Thank you for your time. > Sincerely, > > Jessica Thompson > M.S.
