概括
战略决策中的响应时间 (RT),就像讨价还价一样,揭示了私人信息. 对报价的决定速度较慢表明其质量,但这些信息对于拒绝来说不那么有用,影响买家行为并扩展漂移-扩散模型.
科学领域:
- 行为经济学是一种行为经济学.
- 游戏理论的游戏理论.
- 计算神经科学是一种计算神经科学.
背景情况:
- 游戏理论假设预先计划的策略,但现实世界的决策可能涉及现场比较.
- 非战略决策中的响应时间 (RT) 与选项相似性相关,可能揭示私人信息.
研究的目的:
- 调查RT在战略谈判中是否透露私人信息.
- 测试漂移扩散模型 (DDM) 是否可以解释缓慢的战略决策.
主要方法:
- 来自eBay的现有和实验性讨价还价数据的分析.
- 将漂移-扩散模型 (DDM) 应用于几个小时和几天内发生的决策.
主要成果:
- 无论是买方还是卖方,对于不太有利的报价/拒绝,都会表现出较长的RT.
- 报价大小对RT有因果影响,但对于拒绝而不是接受而言,这种影响较弱.
- 买家不太可能对卖家做出反报,因为拒绝时间很慢.
- 经验丰富的卖家不那么谨慎,更容易接受报价.
结论:
- 战略决策并不总是预先计划的,而RT可以是一个战略变量.
- DDM适用于缓慢的决策,扩大其使用范围超出秒.
- 将RT纳入游戏理论模型对于更准确的预测是必要的.

Robbers Cave

During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

The Anchoring-and-Adjustment Heuristic
7.2K
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...

Self-Evaluation: Self-Enhancement and Self-Verification
5.2K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Framing Effects
7.3K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...
