视知觉学习与注意力的关系

Current research on the connection between visual perceptual learning and attention

随着人们对弱视本质以及大脑神经可塑性研究的深入,视知觉学习的概念被逐渐引入到弱视研究领域。由于视知觉学习过程中可能涉及到注意力机制,而且先前的研究显示二者之间存在相互作用。为进一步认识视知觉学习的本质,从认知神经科学和心理物理学的角度对视知觉学习与注意力关系进行综述,如弱视的视觉缺陷表现形式与发病部位、视知觉学习的特点和机制、注意力在视知觉学习中的作用及视知觉学习对注意力的影响。

As intensive study had gone in the amblyopic essence and plasticity of neural brain,the concept of visual perceptual learning was introduced into the area of amblyopic research gradually.Previous studies showed that the mechanism of attention may involve in the process of perceptual learning.To further understand the nature of perceptual learning,this article reviewed the relationship between perceptual learning and attention based on the cognitive neuroscience and psychophysics,including visual deficits and neural location in amblyopes,the characteristics and mechanism of perceptual learning,the role of attention in perceptual learning,and effects of perceptual learning on attention.
