特定位置的感知学习可以通过双重训练转移到新的位置，其中特征训练（例如，对比）伴随着在新位置的额外位置训练，即使是不相关的任务（例如，方向）。本文研究了位置训练任务的相关性（特征训练）和需求对双训练学习迁移的影响。我们发现，具有不相关任务的位置训练（Gabor与字母判断或对比歧视）限制了游标学习向训练方向的迁移。然而，执行相关的超阈正交游标任务会促使额外的转移到未训练的正交方向。此外，学习迁移的数量可能取决于地点训练的需求和双重训练的过程。这些结果描述了双重训练如何增强已习得的高级决策单元与来自未训练位置的视觉输入之间的功能连接，从而实现跨视网膜位置的学习转移。
Location-specific perceptual learning can be rendered transferrable to a new location with double training, in which feature training (e.g., contrast) is accompanied by additional location training at the new location even with an irrelevant task (e.g. orientation). Here we investigated the impact of relevancy (to feature training) and demand of location training tasks on double training enabled learning transfer. We found that location training with an irrelevant task (Gabor vs. letter judgment, or contrast discrimination) limited transfer of Vernier learning to the trained orientation only. However, performing a relevant suprathreshold orthogonal Vernier task prompted additional transfer to an untrained orthogonal orientation. In addition, the amount of learning transfer may depend on the demand of location training as well as the double training procedure. These results characterize how double training potentiates the functional connections between a learned high-level decision unit and visual inputs from an untrained location to enable transfer of learning across retinal locations.
