The superiority of spaced training, in which repeated training sessions are given with resting intervals, over massed training in learning efficacy has been well established. However, longer duration of total training time has been required for spaced training than massed training because spacing intervals intervene between training sessions in spaced training. Thus, the learning efficacy may not be simply compared between spaced and massed training in terms of "time efficiency." The aim of the present study was to investigate the efficacy of spaced and massed training using adaptation of horizontal optokinetic reflex (hOKR) in mice.
Training paradigms were categorized into seven groups according to the duration of spacing interval, keeping total duration of hOKR training including spacing almost equal in all training paradigms.
The amount of short-term hOKR gain increase immediately after the 60 min hOKR training was not significantly different among seven training paradigms. The hOKR adaptation was still in progress during a spacing interval, and the increment in hOKR gain tended to be greater with the longer spacing interval. The increase in hOKR gain was maintained until 48 hr after the end of training in both massed and spaced training.
The short-term learning effect was not significantly different among training paradigms regardless of spacing interval in hOKR adaptation, which suggests that the spacing effect is robust enough to overcome the shortage of optokinetic training cycles in hOKR adaptation.
重复训练并在训练间隔期间休息的间隔训练，比集中训练在学习效果上具有优越性，这已得到充分证实。然而，由于间隔训练在训练课程之间插入了间隔期，因此与集中训练相比，间隔训练需要更长的总训练时间。因此，“时间效率”方面，不能简单地比较间隔训练和集中训练的学习效果。本研究的目的是使用小鼠水平视动反射（hOKR）适应来研究间隔训练和集中训练的效果。
根据间隔间隔的持续时间，将训练方案分为七组，所有训练方案都保持 hOKR 训练的总持续时间几乎相等。
在 60 分钟 hOKR 训练后，立即增加短期 hOKR 增益的量，在七种训练方案之间没有显著差异。在间隔期间，hOKR 适应仍在进行中，并且随着间隔间隔的延长，hOKR 增益的增量趋于更大。在训练结束后 48 小时，hOKR 增益的增加在集中训练和间隔训练中都得到维持。
在 hOKR 适应中，无论间隔间隔如何，短期学习效果在训练方案之间均无显著差异，这表明间隔效应足够强大，可以克服 hOKR 适应中视动训练周期不足的问题。
