Cleaning Rules

1. If any of the calculated variables are missing, that subject should be listed for exclusion. 2. If Trial Count is not =40, then that subject should be listed for exclusion. 3. If overall performance (average percent correct) is below 50% (chance, in this task), that subject should be listed for exclusion. 4. If average RT is greater than 6000ms that subject should be listed for exclusion.

It is worth considering dropping people with performance >50% on either maintenance or manipulation (rather than just on the average).

If you want to know if your group looks approximately like it should, in every sample run so far, accuracy is lower in manipulation than maintenance, and reaction time is greater in manipulation than maintenance. This should be the first group level analysis, to quickly verify everything is correct. It would be highly unexpected to have a deviation from this pattern, even though the position along the y axis (overall accuracy or RT) may vary, especially in patient groups.
