We revisit a long-standing question in the psycholinguistic and neurolinguistic literature on comprehending morphologically complex words: are prefixes and suffixes processed using the same cognitive mechanisms? Recent work using Magnetoencephalography (MEG) to uncover the dynamic temporal and spatial responses evoked by visually presented complex suffixed single words provide us with a comprehensive picture of morphological processing in the brain, from early, form-based decomposition, through lexical access, grammatically constrained recomposition, and semantic interpretation. In the present study, we find that MEG responses to prefixed words reveal interesting early differences in the lateralization of the form-based decomposition response compared to the effects reported in the literature for suffixed words, but a very similar post-decomposition profile. These results not only address a question stretching back to the earliest days of modern psycholinguistics, but also add critical support and nuance to our much newer emerging understanding of spatial organization and temporal dynamics of morphological processing in the human brain.
前缀和后缀的处理是否使用相同的认知机制？最近利用脑磁图（MEG）来揭示视觉呈现的复杂后缀单字所引发的动态时间和空间反应的研究，为我们提供了大脑中形态处理的全面图景，从早期基于形式的分解，到词汇通达、语法约束的重新组合以及语义解释。在本研究中，我们发现，与文献中报道的后缀单词的效应相比，MEG对前缀单词的反应在基于形式的分解反应的侧化方面显示出有趣的早期差异，但在分解后的模式非常相似。这些结果不仅解决了一个可追溯到现代心理语言学早期的问题，也为我们对人类大脑中形态处理的空间组织和时间动态的最新理解增添了关键的支持和细微差别。
