旨在提高阅读速度的干预措施的一个目标是减少在个人思想中清晰表达单词或默读的做法。这种做法可能需要冗余的认知资源、缓慢的阅读速度，并且有损于书面文字到语义理解的有效转换。然而，目前尚不清楚旨在提高阅读速度的练习是否可以推广到阅读任务本身之外的认知功能。为了研究这种可能性，我们测量了 9 名健康青少年女性志愿者在进行旨在提高阅读速度的认知练习之前和之后古典语言区域的静息状态功能连接。我们发现，与训练前相比，在训练期后的静息状态下，左布罗卡区和右布罗卡同系物之间以及右布罗卡同系物和右韦尼克同系物之间的相关性显着降低。左布罗卡区训练后功能连接的差异显示出空间分布，反映出与记忆相关的大脑区域的相关性降低，而与听觉区域的相关性增加，这可能与这样的假设一致，即这种训练可能会减少静息状态下与语义记忆功能相关的默读。
A goal of interventions designed to increase reading speed is to reduce the practice of articulating words in an individual’s thoughts, or subvocalization. This practice may require redundant cognitive resources, slow reading speed, and detract from efficient transfer of written words to semantic understanding. It is unclear, however, whether exercises designed to promote faster reading speed generalize to cognitive function beyond the reading task itself. To investigate this possibility, we measured resting state functional connectivity in classical language regions before and after a course of cognitive exercise designed to increase reading speed in 9 healthy adolescent female volunteers. We found significantly decreased correlation between left Broca Area and right Broca Homologue and between right Broca Homologue and right Wernicke Homologue in the resting state after the training period compared to before training. Differences in functional connectivity after training to left Broca Area showed a spatial distribution reflecting decreased correlation to memory-associated brain regions and increased correlation to auditory regions, that might be consistent with a hypothesis that such training may decrease subvocalization associated with semantic memory function during the resting state.
