Previous studies found recall errors to be systematically related to the average number of items Ss were required to remember. The present study supplements this work by extending the average storage load to higher values, and by using as items words judged to be unrelated. Recall errors were found to increase regularly with average storage load with related or unrelated items and under conditions where Ss recalled one or several items at each recall point.
