Framing Effects03:26

Framing Effects

7.4K
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...

Timing and Consequences on Behavior01:08

Timing and Consequences on Behavior

90
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective. 
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

Decision Making01:20

Decision Making

107
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

The Availability Heuristic01:08

The Availability Heuristic

6.0K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

The Anchoring-and-Adjustment Heuristic01:25

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...

Hindsight Biases01:12

Hindsight Biases

3.4K
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?

科学领域:

  • 行为经济学是一种行为经济学.
  • 动物认知动物的认知能力.
  • 在不确定性下做决定

背景情况:

  • 奖励预期和信号影响选择行为.
  • 好消息信号 (SiGN) 模型解释了奖励预测刺激如何影响决策.
  • 之前的研究表明,子有时更喜欢被标记为低于最佳的奖励.

研究的目的:

  • 在子中测试SiGN模型的定量预测.
  • 调查选择期持续时间对奖励偏好的影响.
  • 要确定时间上下文是否会改变选择选项的相对值.

主要方法:

  • 子在有信号的20%食物奖励和没有信号的50%食物奖励之间做出选择.
  • 在两个实验中,选择期的持续时间被系统地操纵.
  • 我们对"好消息信号" (SiGN) 模型的预测进行了定量评估.

主要成果:

  • 子更喜欢在较短的选择时间内选择非最佳信号选项.
  • 子在更长的选择时间中更喜欢最佳的无信号选项.
  • 结果强烈支持SiGN模型的预测.

结论:

  • 选择期的持续时间显著地影响了人们对有信号和无信号奖励的偏好.
  • 期权的相对价值是动态的,取决于环境,而不是固定的.
  • SiGN模型准确地预测了受时间因素影响的选择行为.
