婴儿视觉注意的发展

近年来，研究对婴儿的视觉注意进行了大量研究，得到很多有价值的发现。这些发现围绕婴儿注意功能的4个方面，即警觉、空间定向、对物体特征的注意和内源性注意，描述了婴儿视觉注意的发展过程．婴儿出生时，身上已分化出各种注意功能的初级形式，但是，每种注意功能都有不同的发展时期。主要表现在：从出生到2个月，婴儿的警觉状态发生并发展；从2或3个月6个月左右，婴儿的空间定向和物体注意功能有很大的变化；从5或6个月以后，婴儿的内源性注意功能变化明显。

The Development of Visual Attention in Infancy

Recently, researchers have done a lot of studies on attention in infancy,and have got many valuable findings. These findings involve four attentional functions, including alertness, spatial orientation to object features, and endogenous attention, and delineate the developmental course of attention in infancy. Rudimentary form of various attentional functions are present at birth, but each of the functions exhibits different and apparently dissociable periods of postnatal change, for example, the development of the alert state takes place from birth to 2 month; and there are rapid changes in both the spatial orientation and object attention functions from 2 to 3 month. Significant changes in endogenous attentional function have been observed from 5 to 6 month and beyond.
