即使没有反馈，与学习练习相比，测试练习提高了延迟成绩，但影响的大小在不同的研究中是不同的。我们调查了测试的好处，将最初可检索的项与最初不可检索的项分开。在两个实验中，初步测试确定了项目的可检索性。随后提出了可取回或不可取回的物品，以供反复研究或试验练习。在实验一中，通过跨项目折叠，我们得到了保持间隔与练习类型之间典型的交叉交互作用。然而，对于可检索的项目，交叉交互作用在数量上是不同的，即时测试的研究益处较小，延迟测试后的测试益处较大。对于不可检索的项目，立即测试对学习有很大的好处，但一周后，学习和测试练习条件之间没有区别。在实验2中，最初不可提取的项目被给予额外的研究，然后是立即测试或甚至更多的额外研究，一周后，两种条件下的表现没有差别。这些结果表明，研究/测试实践的效果大小是由于可提取项和不可提取项的相对贡献。
Even without feedback, test practice enhances delayed performance compared to study practice, but the size of the effect is variable across studies. We investigated the benefit of testing, separating initially retrievable items from initially non-retrievable items. In two experiments, an initial test determined item retrievability. Retrievable or non-retrievable items were subsequently presented for repeated study or test practice. Collapsing across items, in Experiment 1, we obtained the typical crossover interaction between retention interval and practice type. For retrievable items, however, the crossover interaction was quantitatively different, with a small study benefit for an immediate test and a larger testing benefit after a delay. For non-retrievable items, there was a large study benefit for an immediate test, but one week later there was no difference between the study and test practice conditions. In Experiment 2, initially non-retrievable items were given additional study followed by either an immediate test or even more additional study, and one week later performance did not differ between the two conditions. These results indicate that the effect size of study/test practice is due to the relative contribution of retrievable and non-retrievable items.
