人们被激励寻求对自己的负面社会反,挑战人类本能地避免厌恶刺激的想法. 这种行为与特定的神经机制有关,表明对自我相关信息的复杂驱动.
科学领域:
- 神经科学是一个神经科学.
- 社会心理学 社会心理学
- 信息搜索行为行为.
背景情况:
- 好奇心驱使人们寻求信息,包括对他人有厌恶感的社会信息.
- 尚不清楚个人是否寻求不利的自我相关的社会信息以及潜在的神经机制.
研究的目的:
- 调查个人是否寻求对自己的负面社会反.
- 探索与寻求自我相关的负面社会反相关的神经生理机制.
主要方法:
- 开发了一种新的脑电图兼容的社会激励延迟 (SID) 任务.
- 30名健康的年轻人响应了目标,在他们的Instagram照片上收到积极的评论或避免负面的评论.
- 测量反应时间和脑电图 (EEG) 信号,特别是奖励积极性 (RewP) 和FB-P3.
主要成果:
- 对参与者自己的照片的负面评论而不是积极评论的反应时间较慢,这表明避免负面反的动机较少.
- 与避免负面反相比,收到负面反引起了更大的RewP和FB-P3振幅,特别是在与自身相关的照片中.
- 这表明,收到负面评论比不收到任何评论更有回报和突出.
结论:
- 这些发现挑战了人类本能地避免厌恶刺激的观念.
- 收到负面的自我相关的社会反可以比避免它更有价值和突出.
- 这项研究揭示了神经生理学机制,这些机制是反直觉寻求不利的自我信息的基础.

Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome.

Avoidance learning is powerful because it maintains behavior in the absence of the...
