感知技能可以通过感知任务的练习来提高，即使在成年期也是如此。已知视觉知觉学习主要针对训练的视网膜位置，这被认为是视网膜置换早期视觉皮层神经可塑性的证据。最近的研究结果表明，在一些特定的训练程序下，可以将学习转移到未经训练的地方。在这里，我们评估了外源性注意是否促进知觉学习转移到未训练的位置，包括靠近训练位置（实验1）和远离训练位置（实验2）。结果表明，在这两个实验中，注意力促进了知觉学习向未训练位置的转移，这种转移既发生在视觉半球内部，也发生在视觉半球之间。这些发现表明，外源性注意力训练是一种强大的机制，能够克服位置特异性的主要限制。
Perceptual skills can be improved through practice on a perceptual task, even in adulthood. Visual perceptual learning is known to be mostly specific to the trained retinal location, which is considered as evidence of neural plasticity in retinotopic early visual cortex. Recent findings demonstrate that transfer of learning to untrained locations can occur under some specific training procedures. Here, we evaluated whether exogenous attention facilitates transfer of perceptual learning to untrained locations, both adjacent to the trained locations (Experiment 1) and distant from them (Experiment 2). The results reveal that attention facilitates transfer of perceptual learning to untrained locations in both experiments, and that this transfer occurs both within and across visual hemifields. These findings show that training with exogenous attention is a powerful regime that is able to overcome the major limitation of location specificity.
