对西班牙语语法性别的研究表明，母语使用者利用限定词中的性别线索来促进语音处理，并且对性别不匹配很敏感。然而，过去的研究并没有考虑到男性和女性性别之间的分布不对称，将一种或另一种性别的试验表现纳入单一分析。我们使用事件相关电位来研究男性和女性的语法性别是否会引起质的不同的大脑反应。40名单语西班牙语使用者阅读了格式良好或包含限定词-名词性别违规的句子。一半的名词是男性，另一半是女性。与以前的研究一致，大脑反应变化沿着一个连续的LAN和P600主导的影响，为两个性别类别。然而，研究结果表明，个人的ERP反应优势（LAN/P600）系统性地在两种性别之间存在差异：对男性名词违规行为表现出LAN优势反应的参与者更有可能对女性名词违规行为表现出P600效应。与个体差异的措施的相关性进一步表明，男性名词违规的反应调制的性能上的AX-CPT，认知控制的措施，而女性名词违规的反应调制的词汇知识，作为指标的口头流畅性。总之，结果表明，即使处理属于同一“自然类”的语言特征，母语者也可以表现出与语言使用分布模式相协调的大脑活动模式。因此，在解释其他类型的人群中报告的所谓偏离“本土规范”时，母语者处理的固有变化是一个重要因素。
Studies of Spanish grammatical gender have shown that native speakers exploit gender cues in determiners to facilitate speech processing and are sensitive to gender mismatches. However, past research has not considered attested distributional asymmetries between masculine and feminine gender, collapsing performance on trials with one or the other gender into a single analysis. We use event-related potentials to investigate whether masculine and feminine grammatical gender elicit qualitatively different brain responses. Forty monolingual Spanish speakers read sentences that were well-formed or contained determiner-noun gender violations. Half of the nouns were masculine and the other half were feminine. Consistent with previous research, brain responses varied along a continuum between LAN- and P600-dominant effects for both gender categories. However, results showed that individuals’ ERP response dominance (LAN/P600) systematically differed across the two genders: participants who showed a LAN-dominant response to masculine-noun violations were more likely to show a P600 effect in response to feminine-noun violations. Correlations with individual difference measures further revealed that responses to masculine-noun violations were modulated by performance on the AX-CPT, a measure of cognitive control, whereas responses to feminine-noun violations were modulated by lexical knowledge, as indexed by verbal fluency. Together, the results demonstrate that even when processing features of language that belong to the same “natural class,” native speakers can exhibit patterns of brain activity attuned to distributional patterns of language use. The inherent variability in native speaker processing is, therefore, an important factor when explaining purported deviations from the “native norm” reported in other types of populations.
