与听力正常的儿童相比，听力有困难的儿童面临着语言发育和学业延迟的风险。一些研究表明，包括流体智力在内的高阶认知功能可能与听力损失儿童的语言和学业成果有关，但这些研究的结果参差不齐，而且到目前为止，还没有关于在听力损失情况下服务于流体智力的全脑神经动力学的研究。为此，本研究试图利用脑磁图技术，确定听力损失以及随后使用助听器对听力有困难的儿童相对于听力正常的儿童在服务于抽象推理的神经动力学方面的影响。我们发现，在早期刺激评估过程中，听力有困难的儿童相对于听力正常的同龄人，枕叶和顶叶的θ波活动显著增强。此外，我们还发现，更多地使用助听器与整个额顶网络活动的减少显著相关。值得注意的是，在后期处理过程中，两组之间的α波动力学没有差异，α波活动也与助听器的使用无关。这些横断面数据表明，听觉经验的差异导致儿童流体智力中服务于初始刺激处理的神经动力学发生广泛变化。
海因里希斯 - 格雷厄姆等人报告称，与听力正常的儿童相比，听力损失儿童在抽象推理过程中顶枕叶的θ波活动增强。整个额顶网络的θ波活动也与助听器的使用量有关，这凸显了持续使用助听器对认知和大脑发育的重要性。
Children who are hard of hearing are at risk for developmental language and academic delays compared with children with normal hearing. Some work suggests that high-order cognitive function, including fluid intelligence, may relate to language and academic outcomes in children with hearing loss, but findings in these studies have been mixed and to date, there have been no studies of the whole-brain neural dynamics serving fluid intelligence in the context of hearing loss. To this end, this study sought to identify the impact of hearing loss and subsequent hearing aid use on the neural dynamics serving abstract reasoning in children who are hard of hearing relative to children with normal hearing using magnetoencephalography. We found significant elevations in occipital and parietal theta activity during early stimulus evaluation in children who are hard of hearing relative to normal-hearing peers. In addition, we found that greater hearing aid use was significantly related to reduced activity throughout the fronto-parietal network. Notably, there were no differences in alpha dynamics between groups during later-stage processing nor did alpha activity correlate with hearing aid use. These cross-sectional data suggest that differences in auditory experience lead to widespread alterations in the neural dynamics serving initial stimulus processing in fluid intelligence in children. Heinrichs-Graham et al. report elevations in parieto-occipital theta activity during abstract reasoning in children with hearing loss relative to children with normal hearing. Theta activity throughout the fronto-parietal network was also related to the amount of hearing aid use, underscoring the importance of consistent hearing aid use on cognitive and brain development.
