A longstanding cerebral lateralization hypothesis predicts that disrupted development of typical leftward structural asymmetry of auditory cortex explains why children have problems learning to read. Small sample sizes and small effects, potential sex-specific effects, and associations that are limited to specific dimensions of language are thought to have contributed inconsistent results. The large ABCD study dataset (baseline visit: N = 11,859) was used to test the hypothesis of significant associations between surface area asymmetry of auditory cortex and receptive vocabulary performance across boys and girls, as well as an oral word reading effect that was specific to boys. The results provide modest support (Cohen's effect sizes ≤ 0.10) for the cerebral lateralization hypothesis.
一个长期存在的大脑半球侧化假说预测，听觉皮层典型的向左结构不对称发育受到干扰，这解释了儿童在学习阅读时出现问题的原因。样本量小和效应值小、潜在的性别特异性效应以及仅限于特定语言维度的关联，被认为是导致结果不一致的原因。大型ABCD研究数据集（基线访视：N = 11,859）被用于检验听觉皮层表面积不对称与男孩和女孩的接受性词汇表现之间存在显著关联的假说，以及一种特定于男孩的口语单词阅读效应。结果为大脑半球侧化假说提供了适度支持（科恩效应值≤0.10）。
