概括
这项研究表明,情绪调节 (ER) 策略随着时间的推移影响负面影响 (NA) 和积极影响 (PA). 重新评估负面图像可以减少NA或顺序减少NA,然后增加PA.
科学领域:
- 心理学 心理学 心理学
- 神经科学是一个神经科学.
- 情感科学是一种情感科学.
背景情况:
- 情绪调节 (ER) 是一个复杂,动态的过程,影响情绪状态.
- 了解ER的时间展开对于描述其对情感经验的影响至关重要.
- 之前的研究还没有完全阐明不同ER策略对负面影响 (NA) 和积极影响 (PA) 的时间进程.
研究的目的:
- 在NA和PA上调查ER策略的时间动态.
- 为了确定在ER期间NA和PA的变化是否顺序发生或同时发生.
- 通过中和和转换负面刺激来比较情绪调节的时间过程.
主要方法:
- 参与者观看了不愉快的图像8秒,接下来是没有监管的8秒,中和重新评估或转变重新评估.
- 电动肌图 (EMG) 记录了波纹 (NA) 和腹肌大 (PA) 电动肌图作为客观的生理测量.
- 模型拟合分析检查了不同ER条件下的EMG变化的时间模式.
主要成果:
- 没有任何法规保持高NA (corrugator EMG) 和低PA (zygomaticus EMG).
- 中和重新评估降低了NA (corrugator EMG),但没有影响PA (zygomaticus EMG).
- 转换重新评估连续减少了NA (corrugator EMG) 和增加了PA (zygomaticus EMG),PA变化在NA变化之后出现.
结论:
- 不同的ER目标产生不同的情感变化的时间模式.
- 中和目标会诱导NA的一个维度下降.
- 转换目标促进了连续的二维变化,首先减少NA,然后增加PA.

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...

Emotional expression encompasses how individuals convey their emotions through verbal communication and non-verbal cues. These non-verbal actions include facial expressions, body language, and physical gestures, such as frowning or smiling. Among these, facial expressions play a crucial role in emotional expression and are understood universally, indicating a biological basis for how humans communicate emotions.

01:30Socioemotional Development during Infancy

Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.
