In but one instance, period 6, are there more signs indicating a supe- rior functioning of processes than were found for inferior performances. The usual effect of alcohol would seem to be reversed in the sixth period, so that the subject actually did better in the majority of pro- cesses measured at the end of the alcohol-day experiments than he did
