概括

大脑刺激,特别是对中部前额叶皮层 (MPFC) 的重复性横磁刺激 (rTMS),可以改变吸引力评级. 低频rTMS增加了感知吸引力,而高频rTMS降低了它,这表明MPFC参与了其他人如何感知外表.

科学领域:

神经科学是一个神经科学.
心理学心理学心理学
社会科学社会科学社会科学

背景情况:

以前的研究表明,大脑刺激可以通过影响中部前额叶皮质 (MPFC) 来改变身体外观.
经过1赫兹的跨磁刺激 (TMS) 已被证明可以增加面部表情,观察者可以检测到变化,但不是受试者.

研究的目的:

调查对MPFC应用的重复性跨磁刺激 (rTMS) 是否会影响他人对个人的吸引力评价.
探索MPFC在调节吸引力认知中的作用.

主要方法:

第一阶段:十名受试者在五种不同的刺激条件下接受了针对MPFC的rTMS,拍摄照片并收集自我评价.
第二阶段:430名参与者对第一阶段个人照片的吸引力进行评分.
分析的重点是自我评估的吸引力 (第一阶段) 和外部吸引力评级 (第二阶段) 遵循不同的rTMS频率 (1 Hz vs. 10 Hz).

主要成果:

在第一阶段的rTMS后,没有观察到自我评价吸引力的显著变化.
在第二阶段,其他人的吸引力评级显示出基于rTMS的显著差异.
对MPFC的1 Hz rTMS导致个人被评为更有吸引力,而10 Hz rTMS导致吸引力评级较低 (p < 0.001).

结论:

中间前额叶皮质在调节感知的吸引力方面发挥着重要作用.
大脑刺激,特别是rTMS,可以改变一个人的外表,以其他人的感知方式,但仍然低于主体的意识.
这项研究是第一个证明大脑刺激与吸引力评级的变化之间存在直接联系的研究.

关键词:

Nonconscious Mimicry

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.

Subliminal Perception

Subliminal Perception

Subliminal perception refers to the processing of sensory information that occurs below the level of conscious awareness. Researchers study subliminal perception by presenting a stimulus, such as a word or image, very quickly, typically around 50 milliseconds. This rapid presentation is often followed by another stimulus, such as a pattern of dots or lines, which blocks further mental processing of the initial stimulus. As a result, if participants cannot identify the initial stimulus better...

Attitudes

Attitudes

Attitude is our evaluation of a person, an idea, or an object. We have attitudes for many things ranging from products that we might pick up in the supermarket to people around the world to political policies. Typically, attitudes are favorable or unfavorable: positive or negative (Eagly & Chaiken, 1993). And, they have three components: an affective component (feelings), a behavioral component (the effect of the attitude on behavior), and a cognitive component (belief and knowledge;...
