In this study, we addressed the influence of individual differences in personality traits measured trough a Big Five personality test, and sociodemographic variables such as age or gender, in the processing of words conveying discrete emotions. To this aim, we relied on data from a large-scale lexical decision task in Spanish. The analyses with linear mixed models revealed several interactions between emotional content and both personality traits and sociodemographic factors during word recognition. In this sense, there was a facilitation for fear-related words, mainly in male participants. Also, disgust interacted with agreeableness and conscientiousness, showing an inhibition for disgust-related words in participants scoring low in agreeableness or high in conscientiousness. Sadness-related words were processed more slowly in men, while this effect was absent in women. Finally, happiness-related words showed an interaction with openness to experience, age and gender. We discuss the complex interplay between the emotional connotation of words and individual differences. All in all, our findings emphasise the need to take individual characteristics into account when examining emotional word processing.
在本研究中，我们探讨了通过大五人格测试测量的人格特质个体差异，以及年龄或性别等社会人口统计学变量对传达离散情绪的词汇加工的影响。为此，我们依赖于来自一项大规模西班牙语词汇判断任务的数据。线性混合模型分析揭示了在单词识别过程中，情绪内容与人格特质和社会人口统计学因素之间的几种相互作用。从这个意义上说，对与恐惧相关的单词存在促进作用，主要体现在男性参与者中。此外，厌恶与宜人性和尽责性相互作用，在宜人性得分低或尽责性得分高的参与者中，对与厌恶相关的单词表现出抑制作用。与悲伤相关的单词在男性中加工得更慢，而在女性中则没有这种效应。最后，与快乐相关的单词与经验开放性、年龄和性别存在相互作用。我们讨论了单词的情感内涵与个体差异之间的复杂相互作用。总而言之，我们的研究结果强调在研究情绪词汇加工时需要考虑个体特征。
