视觉感知学习(VPL)通常特定于训练的位置和特征。然而,特异性的程度取决于特定的训练方案。在训练过程中操纵内隐空间注意有助于学习迁移到其他位置。在这里,我们调查了是否基于特征的注意力(FBA),这增强了整个视野中的特定功能的表示,促进VPL传输,以及这种效果会持续多久。要做到这一点,我们实现了一个新的任务,观察员歧视的刺激方向相对于两个参考角度同时提出之前,每个块。我们发现,与FBA的培训,使显着的位置转移,让人想起其在整个视野的全球影响,但保留在VPL的方向特异性。重要的是,知觉改善和位置转移持续1年后。我们的研究结果揭示了FBA在VPL中诱导的强大,持久的益处,并对改善视觉康复训练方案的泛化具有翻译意义。
Visual perceptual learning (VPL) is typically specific to the trained location and feature. However, the degree of specificity depends upon particular training protocols. Manipulating covert spatial attention during training facilitates learning transfer to other locations. Here we investigated whether feature-based attention (FBA), which enhances the representation of particular features throughout the visual field, facilitates VPL transfer, and how long such an effect would last. To do so, we implemented a novel task in which observers discriminated a stimulus orientation relative to two reference angles presented simultaneously before each block. We found that training with FBA enabled remarkable location transfer, reminiscent of its global effect across the visual field, but preserved orientation specificity in VPL. Critically, both the perceptual improvement and location transfer persisted after 1 year. Our results reveal robust, long-lasting benefits induced by FBA in VPL, and have translational implications for improving generalization of training protocols in visual rehabilitation.
