创造和保持一个物体的心理图式的能力是认知发展的里程碑之一。发展科学家将这种能力对象的行为表现形式命名为永久性。一致的证据表明，额叶成熟在展示物体永久性方面发挥了关键作用，但方法和伦理限制使得从清醒的、行为正常的婴儿中收集神经生理学证据变得困难。近红外光谱学提供了对指定区域内氧合和脱氧血红蛋白以及总血红蛋白浓度变化的非侵入性评估。这份报告中描述的证据表明，物体永久性的出现与额叶皮质中血红蛋白浓度的增加有关。(C)2002年埃尔塞维尔科学公司(美国)。
The ability to create and hold a mental schema of an object is one of the milestones in cognitive development. Developmental scientists have named the behavioral manifestation of this competence object permanence. Convergent evidence indicates that frontal lobe maturation plays a critical role in the display of object permanence, but methodological and ethical constrains have made it difficult to collect neurophysiological evidence from awake, behaving infants. Near-infrared spectroscopy provides a noninvasive assessment of changes in oxy- and deoxyhemoglobin and total hemoglobin concentration within a prescribed region. The evidence described in this report reveals that the emergence of object permanence is related to an increase in hemoglobin concentration in frontal cortex. (C) 2002 Elsevier Science (USA).
