摘要
语音意识(PA)是阅读的重要预测因素和结果。然而,在没有持续阅读经验的情况下(例如,由于接受优质教育的机会有限和入学较晚),人们对语音意识与阅读之间的相互关系知之甚少。我们测试了一个假设,即童年时期不同的阅读经历会影响语言和阅读处理相关区域--左额叶和颞顶叶皮层--的神经激活。来自科特迪瓦农村低文化水平社区的 69 名小学生(Mage = 10.4)在完成 PA 任务的同时,还接受了功能性近红外光谱神经成像(fNIRS)和阅读测试。我们观察到,在阅读技能相似的情况下,年龄较小的儿童与年龄较大的儿童在左侧额叶下部和双侧颞顶叶激活方面存在差异,这表明语音处理的神经激活取决于儿童拥有阅读经验的年龄。如果没有持续接受优质教育的机会,儿童可能会错过语音处理与阅读之间的相互影响,从而影响大脑中的语言处理。
Neural Activation during Phonological Processing in Primary‐School Children with Limited Reading Experience: Insights from Rural Côte d'Ivoire
Phonological awareness (PA) is an important predictor and outcome of reading. Yet, little is known about the reciprocal relation between PA and reading across development without consistent reading experience (e.g., as a result of limited access to quality education and late enrolment in school). We tested the hypothesis that variable reading experience in childhood influences neural activation in regions involved in language and reading processing—left frontal and temporoparietal cortex. Sixty‐nine primary‐school children (Mage = 10.4) from rural low‐literacy communities in Côte d'Ivoire completed a PA task while undergoing functional near‐infrared spectroscopy neuroimaging (fNIRS) neuroimaging and a reading battery. We observed differences in left inferior frontal and bilateral temporoparietal activation for younger versus older children with similar reading skills, suggesting neural activations for phonological processing depends on the age when children have reading experience. Without consistent access to quality education, children may miss out on reciprocal interactions between phonological processing and reading shaping language processing in the brain.
期刊介绍:
Mind, Brain, and Education (MBE), recognized as the 2007 Best New Journal in the Social Sciences & Humanities by the Association of American Publishers" Professional & Scholarly Publishing Division, provides a forum for the accessible presentation of basic and applied research on learning and development, including analyses from biology, cognitive science, and education. The journal grew out of the International Mind, Brain, and Education Society"s mission to create a new field of mind, brain and education, with educators and researchers expertly collaborating in integrating the variety of fields connecting mind, brain, and education in research, theory, and/or practice.
