This ERP study employed an N2pc paradigm to investigate possible functional interactions between mechanisms of visual spatial attention and grammatical gender processing. Previous studies showed that the N2pc, an attention-related ERP component, can be modulated by lexical-semantic variables. However, it remains to be seen whether the N2pc can be affected by grammatical features as well. To test this, we conducted an N2pc study with Italian word pairs whose grammatical gender either agreed or disagreed. Participants read a centrally presented noun followed by an adjective in a lateralized position during a gender agreement task. Between 170 and 310ms, the N2pc was elicited contralaterally to the adjective position with a left-lateralized effect of the agreement manipulation. These results suggest that this component could be influenced by grammatical features, supporting a functional interaction between processes mediating visual spatial attention and agreement computation.
这项 ERP 研究采用 N2pc 范式，旨在探究视觉空间注意机制与语法性别处理之间可能存在的功能交互。先前的研究表明，N2pc 是一种与注意力相关的 ERP 成分，它可以被词汇语义变量调节。然而，目前尚不清楚 N2pc 是否也可以受到语法特征的影响。为了验证这一点，我们进行了一项 N2pc 研究，使用意大利语单词对，其语法性别要么一致，要么不一致。参与者在性别一致任务中阅读中央呈现的名词，然后在侧化位置阅读形容词。在 170 到 310 毫秒之间，与形容词位置相对的 N2pc 被诱发，并且与协议操作的左侧效应一致。这些结果表明，该成分可能受到语法特征的影响，支持介导视觉空间注意和一致性计算的过程之间的功能交互。
