This study investigated whether the visual recognition of neutral words might be influenced by the emotional dimensions (i.e., valence and arousal) of orthographically similar lexical representations, and whether this might also depend on emotional-related traits of participants (i.e., alexithymia). To this end, 108 participants performed a lexical decision task with 80 neutral words with a higher frequency orthographic neighbor that varied in valence (from neutral to negative) and arousal (from low to high). The main finding was the expected interaction effect between the valence and arousal of the neighbor on the lexical decision times of neutral stimulus words. Longer reaction times were found when the valence score of the neighbor decreased from neutral to negative for words with a low-arousal orthographic neighbor while this emotional neighbor effect was reversed for words with a high-arousal negative neighbor. This combined influence of the valence and arousal of the neighbor was interpreted in terms of increased lexical competition processes and direct influence of the affective system on the participant's response. Moreover, this interaction effect was smaller when the level of alexithymia of the participants increased, suggesting that people with a higher level of alexithymia are less sensitive to the emotional content of the neighbor. The results are discussed within an interactive activation model of visual word recognition incorporating an affective system with valence and arousal dimensions, with regard to the role of the alexithymia level of participants.
本研究旨在探讨在视觉识别中性词时，词的正性度和唤醒度等情绪维度是否会对其产生影响，以及这种影响是否与参与者的情绪特质（即述情障碍）有关。为此，108 名参与者完成了一项词汇判断任务，其中包括 80 个正性度（从中性到负性）和唤醒度（从低到高）不同的高频词的近形词。主要发现是近形词的正性度和唤醒度与中性刺激词的词汇判断时间之间存在预期的交互效应。当近形词的正性度从中性变为负性时，低唤醒度的近形词的反应时间会延长，而当近形词的正性度为高唤醒度的负性时，这种情绪近形词效应则相反。这种近形词的正性度和唤醒度的综合影响可以用词汇竞争过程的增加和情感系统对参与者反应的直接影响来解释。此外，当参与者的述情障碍水平升高时，这种交互效应会减小，这表明述情障碍水平较高的人对近形词的情绪内容不太敏感。研究结果在一个结合了正性度和唤醒度维度的情感系统的视觉词汇识别的交互式激活模型中进行了讨论，同时考虑了参与者的述情障碍水平的作用。
