Trace eyeblink conditioning is used as a translational model of declarative memory but restricted to the temporal domain. Potential spatial aspects have never been experimentally addressed. We employed a spatiotemporal trace eyeblink conditioning paradigm in which a spatial dimension (application side of the unconditioned stimulus) was differentially coded by tone frequency of the conditioned stimulus and recorded conditioned reactions from both eyes. We found more and stronger conditioned reactions at the side predicted by the conditioned stimulus but only in aware participants. Thus, spatial effects are present in trace eyeblink conditioning and may be differentially conditioned depending on the awareness about the spatial relation between conditioned and unconditioned stimulus.

:Trace眨眼条件用作声明性记忆的翻译模型,但仅限于时域。潜在的空间方面从未实验性地解决过。我们采用了时空迹线眨眼条件范式,其中空间维度(未条件刺激的应用侧)通过条件刺激的音调频率进行差分编码,并记录了两只眼睛的条件反应。我们在条件刺激所预测的一侧发现了更多且更强的条件反应,但仅在有意识的参与者中。因此,空间效应存在于微量眨眼条件中,并且可以根据对条件刺激与非条件刺激之间的空间关系的了解而有区别地进行调节。
