概括

不平等的奖励分配影响了专家和新手之间的社交互动和大脑同步. 当奖励对他们有利时, 新手会受益, 显示神经协调增强,

科学领域:

神经科学
社会心理学
经济学

背景情况:

社会互动对于合作至关重要,
奖励分配不平等如何影响社会互动的神经基础, 特别是在专家-新手双重关系中, 仍然在很大程度上未被探索.

研究的目的:

调查不同奖励分配策略 (平等,专家优势,新手优势) 在联合任务期间对专家新手双层的行为和神经效应.
通过奖励结构和与行为结果的关系来检查大脑间同步 (IBS) 是如何调节的.

主要方法:

使用功能近红外光谱 (fNIRS) 超扫描测量执行点位置估计任务的二极管中的大脑活动.
根据基准表现和经过操纵的奖励分配,将参与者分类为"专家"或"新手"在三个条件上:平等分配 (ED),专家优势 (EA) 和新手优势 (NA).

主要成果:

在ED和NA条件下,新手从行为上受益,而不是EA. 在ED和NA中显示出更大的妥协 (相互影响).
在EA中,特定的大脑区域 (专家前极和初学者rTPJ/DLPFC) 之间的脑间同步 (IBS) 是最高的.
与ED相比,EA和NA都增加了前执行职位的IBS,NA通过协调特别提高了新手的好处. 这表明神经协作是有效的.

结论:

不平等的奖励分配大大改变了专家和新手之间的神经合,
奖励结构有利于新手保持行为互动的好处,同时促进明显的前执行神经同步.
研究结果揭示了在协作环境中通过奖励分配形成的适应性社会和神经动态.

The Anchoring-and-Adjustment Heuristic

The Anchoring-and-Adjustment Heuristic

In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Decision Making: Traditional Method

Decision Making: Traditional Method

The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

Hindsight Biases

Hindsight Biases

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Reason and Intuition

Reason and Intuition

The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...
