童年贫困与晚年认知老化：加速还是延缓?

童年贫困与晚年认知老化的关系尚存争议。有的研究表明, 童年贫困会加速个体的认知老化, 但是也有研究发现童年贫困会延缓个体的认知老化, 这与社会流动性起到的调节作用有关。对于童年贫困个体, 低稳定或者社会经济地位的向下流动(即长期贫困)会使逆境产生的消极影响不断累积, 从而加速个体的认知老化; 而心理韧性高的童年贫困个体, 可能会促使社会经济地位向上流动, 这会增加个体的认知储备, 并提升特定认知能力, 进而延缓认知老化。今后该领域的研究应该探讨童年主观贫困与认知老化之间的关系以及童年贫困对不同认知能力老化的影响, 也应关注童年贫困与晚年认知老化关系研究中的幸存者偏差效应。

Childhood poverty and cognitive aging

How the childhood poverty influences cognitive aging remains controversial.Some studies have shown that childhood poverty can accelerate individual cognitive aging,but other studies have found that childhood poverty can delay individual cognitive aging,which is related to the moderation of social mobility.For poor individuals in childhood,low stability or the downward mobility of socioeconomic status will make the negative effects of adversity accumulate continuously,thus accelerating the cognitive aging of individuals.However,poor childhood individuals with high psychological resilience may promote upward socioeconomic mobility,which will increase the individual's cognitive reserve and enhance specific cognitive abilities,thus delaying cognitive aging.Future research in this field should explore the relationship between childhood subjective poverty and cognitive aging and the influence of childhood poverty on the aging of different cognitive abilities.It should also focus on the survivor bias effect in studies on the relationship between childhood poverty and cognitive aging in later life.
