The manuscript reports a study on a large sample (N = 170) of Polish speaking 8-13 year old children, whose brain activation was measured in relation to tasks that require auditory phonological processing. We aimed to relate brain activation to individual differences in reading and spelling. We found that individual proficiency in both reading and spelling significantly correlated with activation of the left ventral occipito-temporal cortex encompassing the Visual Word Form Area which has been implicated in automatic orthographic activations. Reading but not spelling was found to correlate with activation in the left anterior dorsal stream (anterior supramarginal and postcentral gyri). Our results indicate that the level of both reading and spelling is related to activity in areas involved in the storage of fine-grained orthographic representations. However, only the reading level is uniquely related to activity of regions responsible for the articulation, motor planning and grapheme-to-phoneme correspondence, which form the basis for effective decoding skill.
本文报告了一项针对 170 名讲波兰语的 8-13 岁儿童的大样本研究，这些儿童的大脑激活情况与需要听觉语音处理的任务有关。我们旨在将大脑激活与阅读和拼写的个体差异联系起来。我们发现，阅读和拼写的个体熟练程度与包含视觉词形区的左侧腹侧枕颞叶皮层的激活显著相关，该区域与自动正字法激活有关。我们发现阅读与左侧前背侧流（前缘上回和后中央回）的激活有关，而拼写则没有。我们的结果表明，阅读和拼写的水平都与涉及精细正字法表示存储的区域的活动有关。然而，只有阅读水平与负责发音、运动规划和字形到音素对应关系的区域的活动有关，这些区域构成了有效解码技能的基础。
