本研究的目的是探讨性别和数量形态特征的整合过程，因为它已经提出，语法性别和数量特征可能与不同的强度与词干在词汇表征。事件相关电位（ERPs）记录使用128通道传感器网络，而24名志愿者阅读西班牙语单词对，并进行句法判断任务。名词和形容词（如faroalto [灯塔-高]）组成的词对在性或数或性和数同时一致或不一致时，均能产生负性，负性的后验分布与词汇整合过程有关。性别不一致、数字不一致和双重不一致之间不存在显著差异。因此，事件相关电位表明，性别和数量特征的整合可能没有不同，并且不一致的检测可能在二元状态下起作用，因为双重不一致条件与其他条件没有区别。此外，随后的组成部分（确定为P3）显示延迟潜伏期的性别分歧条件相比，数量分歧条件，而双重分歧条件下，表现出较短的峰值潜伏期比其他两个分歧条件和类似的协议条件。与分类过程相关的P3成分的延迟变化表明，与一个不一致特征相比，这些过程很快就被两个不一致特征的积累所触发，并且在性别不一致的情况下，重新分析的成本更高与数字不一致相比。
The aim of the current study was to explore the integration processes of gender and number morphological features, since it has been proposed that grammatical gender and number features might be associated with different strength with the word stem in lexical representation. Event related potentials (ERPs) were recorded using a 128-channel sensor net while twenty-four volunteers read Spanish word pairs and performed a syntactic judgment task. The word pairs which could agree or disagree in gender or number or in gender and number at the same time, were formed by a noun and an adjective (e.g. faroalto [lighthouse-high]).A negativity around 400 msec with posterior distribution, which has been related to lexical integration processes, was found in response to both gender and number violations. No differences were found between gender disagreement, number disagreement and the double disagreement. Therefore, ERPs suggest that integration of gender and number features may not be different, and that the detection of disagreement may work under a binary state, since the double disagreement condition did not differ from the others. In addition, a subsequent component (identified as P3) showed delayed latencies in the gender disagreement condition as compared to the number disagreement condition, while the double disagreement conditions showed a shorter peak latency than the other two disagreement conditions and similar to the agreement condition. The variations in the latency of the P3 component, which has been related to categorization processes, suggest that these processes are quickly triggered by the accumulation of two incongruent as compared to one disagreement features, and that reanalysis is costlier in the case of gender disagreement as compared to the number disagreement.
