运动方向学习是已知的特定于训练的方向。然而，在这项研究中，我们使用了我们最近开发的TPE(训练+暴露)方法来证明运动方向学习可以转移到相反的方向。具体地说，我们首先用一组运动点复制了运动方向学习的严格方向特异性。然而，当参与者在不相关的点数辨别任务中接触到相反的方向时，无论是在运动方向训练的同时，还是在稍后的时间，但不是以相反的顺序，运动方向学习显著地转移到相反的方向，有时甚至完全转移。这些结果表明，运动方向学习可能是一个高水平的过程，在这个过程中，大脑学习到重新加权运动方向输入的潜在可迁移规则。然而，我们推测，高水平的学习可能不会在功能上连接到被调到其他方向但在训练中没有受到刺激的感觉神经元，这导致了方向特异性。正是TPE训练中的刺激暴露将高水平的学习与暴露的相反方向联系起来，从而实现学习迁移。
Motion direction learning is known to be specific to the trained direction. However, in this study we used our recently developed TPE (training-plus-exposure) method to demonstrate that motion direction learning can transfer to an opposite direction. Specifically, we first replicated the strict direction specificity of motion direction learning with a group of moving dots. However, when the participants were exposed to the opposite direction in an irrelevant dot number discrimination task, either simultaneously with motion direction training or at a later time, but not in a reversed order, motion direction learning transferred to the opposite direction significantly and sometimes completely. These results suggest that motion direction learning may be a high-level process in which the brain learns the potentially transferrable rules of reweighting the motion direction inputs. However, we speculate that high-level learning may not functionally connect to sensory neurons that are tuned to other directions but are not stimulated during training, which leads to direction specificity. It is the stimulus exposure in TPE training that connects high-level learning to the exposed opposite direction to enable learning transfer.
