感知学习往往表现出实质性的和持久的变化,由于实践的能力,相关的感知刺激分类。对训练刺激和任务的特异性是视知觉学习的一个关键特征,但关于特异性是否取决于初始训练的程度却知之甚少。使用方向辨别任务,我们表明,特异性遵循广泛的培训后,而感知学习的最早阶段表现出大量转移到一个新的位置和相反的方向。简短的培训显示出在转移点的最佳表现。这些研究结果对理解知觉专业知识具有理论和实践意义。
Perceptual learning often shows substantial and long-lasting changes in the ability to classify relevant perceptual stimuli due to practice. Specificity to trained stimuli and tasks is a key characteristic of visual perceptual learning, but little is known about whether specificity depends upon the extent of initial training. Using an orientation discrimination task, we demonstrate that specificity follows after extensive training, while the earliest stages of perceptual learning exhibit substantial transfer to a new location and an opposite orientation. Brief training shows the best performance at the point of transfer. These results for orientation-location transfer have both theoretical and practical implications for understanding perceptual expertise.
