| Abstract | | The investigation is concerned with individual items instead of lists. "Forgetting over intervals measured in seconds was found. The course of retention after a single presentation was related to a statistical model. Forgetting was found to progress at differential rates dependent on the amount of controlled rehearsal of the stimulus. A portion of the improvement in recall with repetitions was assigned to serial learning within the item, but a second kind of learning was also found." |
