This study was designed to investigate if the working memory profiles of children living in rural poverty are distinct from the working memory profiles of children living in urban poverty. Verbal and visuospatial working memory tasks were administered to sixth-grade students living in low-income rural, low-income urban, high-income rural, and high-income urban developmental contexts. Both low-income rural and low-income urban children showed working memory deficits compared with their high-income counterparts, but their deficits were distinct. Low-income urban children exhibited symmetrical verbal and visuospatial working memory deficits compared with their high-income urban counterparts. Meanwhile, low-income rural children exhibited asymmetrical deficits when compared with their high-income rural counterparts, with more extreme visuospatial working memory deficits than verbal working memory deficits. These results suggest that different types of poverty are associated with different working memory abilities.
本研究旨在调查生活在农村贫困地区的儿童的工作记忆概况是否与生活在城市贫困地区的儿童的工作记忆概况不同。对生活在低收入农村、低收入城市、高收入农村和高收入城市发展环境中的六年级学生进行了言语和视觉空间工作记忆任务测试。与高收入儿童相比,低收入农村和低收入城市儿童均表现出工作记忆缺陷,但他们的缺陷有所不同。与高收入城市儿童相比,低收入城市儿童表现出对称的言语和视觉空间工作记忆缺陷。与此同时,与高收入农村儿童相比,低收入农村儿童表现出不对称的缺陷,视觉空间工作记忆缺陷比言语工作记忆缺陷更为严重。这些结果表明,不同类型的贫困与不同的工作记忆能力相关。
