Although the ability to perceive simple shapes emerges in infancy, the ability to recognize individual objects as well as adults do continues to develop through childhood into adolescence. Despite this slow development, recent neuroimaging studies have revealed that an area of the ventral visual cortex that responds selectively to the category of common objects is adult-like by 5-8 years of age. The challenge for future research will be to identify the specific visual skills involved in object recognition that continue to develop through childhood and adolescence, and the neural mechanisms underlying this protracted development.
尽管感知简单形状的能力在婴儿期就已出现,但像成年人一样识别单个物体的能力在童年到青春期仍持续发展。尽管发展缓慢,但最近的神经影像学研究表明,腹侧视觉皮层中对常见物体类别有选择性反应的区域在5至8岁时就已类似成人。未来研究面临的挑战将是确定在童年和青春期持续发展的物体识别所涉及的特定视觉技能,以及这种长期发展背后的神经机制。
