腹侧颞叶皮层中涉及对词语和面孔等类别的视觉识别的区域在儿童时期经历了不同的发展。然而，类别也表现在高层次视觉皮层的分布式反应中。分布式类别表征是如何发展的，以及这种发展是否与识别中的行为变化有关，在很大程度上仍然是未知的。在这里，我们使用功能性磁共振成像纵向测量的发展腹侧颞叶皮层的10个类别的学龄儿童在几年内的分布反应。我们的研究结果揭示了随着年龄的增长，类别表征的增强和减弱，这主要是由类别选择体素的变化驱动的。在左半球的词语和两侧的面孔中，表征变得特别明显。关键的是，在左侧和右侧腹侧颞叶皮层的类别选择体素的单词和面孔的独特性，分别预测个别儿童的单词和面孔识别性能。这些结果表明，分布在腹侧颞叶皮层的发展有行为的分歧，并推进我们的理解，在儿童期延长皮层的发展。观察像面孔或单词这样的类别，会在高级视觉皮层中产生独特的反应模式。在这里，作者表明，面部和单词的分布模式在儿童时期变得更加明显，并预测儿童的识别能力。
Regions in ventral temporal cortex that are involved in visual recognition of categories like words and faces undergo differential development during childhood. However, categories are also represented in distributed responses across high-level visual cortex. How distributed category representations develop and if this development relates to behavioral changes in recognition remains largely unknown. Here, we used functional magnetic resonance imaging to longitudinally measure the development of distributed responses across ventral temporal cortex to 10 categories in school-age children over several years. Our results reveal both strengthening and weakening of category representations with age, which was mainly driven by changes across category-selective voxels. Representations became particularly more distinct for words in the left hemisphere and for faces bilaterally. Critically, distinctiveness for words and faces across category-selective voxels in left and right lateral ventral temporal cortex, respectively, predicted individual children’s word and face recognition performance. These results suggest that the development of distributed representations in ventral temporal cortex has behavioral ramifications and advance our understanding of prolonged cortical development during childhood. Viewing categories like faces or words elicits unique patterns of responses in high-level visual cortex. Here, the authors show that distributed patterns for faces and words become more distinct during childhood and predict children’s recognition ability.
