Motivational congruency has been examined using tasks where participants perform approach or avoidance movements towards socially positive or negative faces. Language is tightly intertwined with interpersonal cognition. Thus, similar situations could be represented by means of language in interpersonal contexts: adjectives furnish valence to people (e.g. someone is cordial or arrogant), and attitudinal verbs define direction to relationship-actions: approach-avoidance (e.g. accept vs. reject). In an Electroencephalography (EEG) study, 40 participants were presented with sentences where a character was valenced (e.g. "Arthur is cordial/arrogant") before being the target of a relationship-actions ("Grisela welcomed/ignored Arthur at the party"). We analyzed both Event-related potential (ERP) amplitude and time-frequency power in response to the attitudinal verb. For ERP amplitudes, we found a significant cluster between 280 and 370 ms, covering part of the development of a N400-like ERP component. This cluster reflects an interaction driven by congruency between motivational direction and target valence. Likewise, time-frequency power analysis revealed an enhancement of theta rhythms under incongruent conditions, most likely indexing conflict processing. Results support that relationship-actions are represented as approach and avoidance and thus involve conflict processing and resolution of incongruent situations. Implications for the interweaving of affective language and social cognition within Embodiment Simulation Theory are discussed.
动机一致性已通过要求参与者对社会正面或负面面孔做出接近或回避动作的任务进行了检验。语言与人际认知紧密交织。因此，类似的情况可以通过人际语境中的语言来表示：形容词赋予人们（例如，某人亲切或傲慢）以情绪，而态度动词则定义了关系行为的方向：接近回避（例如，接受与拒绝）。在一项脑电图（EEG）研究中，40 名参与者首先看到一个角色被赋予了情绪（例如，“亚瑟亲切/傲慢”），然后该角色成为关系行为的目标（例如，“格里塞拉在聚会上欢迎/忽视了亚瑟”）。我们分析了与态度动词相关的事件相关电位（ERP）幅度和时频功率。对于 ERP 幅度，我们发现了一个在 280 到 370 毫秒之间的显著集群，涵盖了 N400 样 ERP 成分的一部分发展。该集群反映了由动机方向与目标情绪一致性驱动的相互作用。同样，时频功率分析显示在不一致条件下θ节律增强，很可能是冲突处理的指标。结果支持关系行为被表示为接近和回避，因此涉及冲突处理和解决不一致情况。讨论了情感语言和社会认知在体现模拟理论中的交织。
