概括

情感隐喻需要比字面陈述更多的认知努力. 通过与事件相关的潜力 (ERP) 测量的大脑活动,显示出基于隐喻理解过程中的情感内容和任务需求的独特模式.

科学领域:

认知神经科学认知神经科学
心理语言学心理语言学
语言的神经科学语言的神经科学

背景情况:

比喻性语言处理与字面语言相比,需要更大的认知神经资源.
与事件相关的潜力 (ERP) 如N400,晚期积极性 (LP) 和晚期消极性 (LN) 已被用来研究这些差异.
刺激情绪和任务需求对这些神经相关的影响仍然未被充分探索.

研究的目的:

调查刺激情绪和任务需求如何调节与事件相关的潜力 (ERP) 与隐喻理解相关.
为了确定情绪内容,任务要求和神经处理的交互,比喻与字面表达的表达.

主要方法:

使用事件相关潜力 (ERP) 进行了两项实验.
实验1:参与者对情感/中性隐喻/字面句子进行了感性判断任务.
实验2:参与者被动阅读句子,通过偶尔的问题来验证理解.

主要成果:

与情感字面句子相比,情感隐喻在实验1中引起了广泛的N400效应和左前后消极性 (LN).
在实验2中,情感隐喻比情感字面句子引起了更积极的后期积极性 (LP).
研究结果表明,情绪和任务需求都会影响参与隐喻处理的神经资源.

结论:

刺激情绪和任务需求相互作用,塑造神经对比喻的处理.
这些因素共同决定了在理解过程中招募情感和语义相关的神经网络.
了解这些影响对于一个全面的比喻语言处理模型至关重要.

关键词:

Cognitive Theories: Lazarus Mediational Theory of Emotion

Cognitive Theories: Lazarus Mediational Theory of Emotion

Richard Lazarus' cognitive mediational theory highlights the pivotal role of cognitive appraisal in shaping emotional responses. According to this theory, the evaluation of a stimulus — based on personal values, goals, beliefs, and expectations — mediates the emotional response. This appraisal process is immediate and often occurs unconsciously, influencing the intensity and nature of the resulting emotion.
Cognitive Appraisal and Emotional Response
Lazarus proposed that...

Cognitive Theories: Schachter-Singer Theory of Emotion

Cognitive Theories: Schachter-Singer Theory of Emotion

Stanley Schachter and Jerome Singer proposed the two-factor theory of emotion, which emphasizes the interplay between physiological arousal and cognitive labeling in forming emotional experiences. This theory suggests that emotions are not simply a result of physiological responses but rather a combination of these responses and the individual's cognitive interpretation of them.
Physiological Arousal and Cognitive Labeling
According to this theory, when an individual experiences...

Facial Feedback Hypothesis

Facial Feedback Hypothesis

Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Factors Affecting Perception

Factors Affecting Perception

Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...
