在226名6 ~ 88岁的个体中，研究了后向模式掩蔽下视觉识别的年龄相关性增益和损失。参与者在高刺激质量和低刺激质量以及不同刺激开始不同步的情况下休闲时识别被掩盖的符号。从童年到成年早期，表现有所增加，然后下降，描述了常见的倒U形功能。然而，一般处理速度的措施解释了儿童和青少年的收益，但不是老年人的损失。儿童发育和衰老之间的这种不对称性与认知发展的一般因素寿命理论不一致，并表明儿童发育和衰老过程中视觉识别的具体机制是不同的。
The age-correlated gains and losses in visual identification under backward pattern masking were studied in a representative sample of 226 individuals ranging from 6 to 88 years of age. Participants identified masked symbols at leisure under high and low stimulus quality and at varying Stimulus Onset Asynchronies. Performance increased from childhood to early adulthood and then decreased, describing the common inverted U-shaped function. However, measures of general processing speed accounted for the gains in childhood and adolescence but not for losses in older age. This asymmetry between child development and aging is inconsistent with general-factor lifespan theories of cognitive development and suggests that specific mechanisms underlying visual identification during child development and aging are different.
