概括
学习陷导致人们错过动态环境中的变化. 即使受到警告,陷入陷的人仍然对新规则视而不见,阻碍了适应性决策.
科学领域:
- 认知心理学 认知心理学
- 行为经济学是一种行为经济学.
- 机器学习理论机器学习理论
背景情况:
- 学习陷发生在最初的经验创造了关于奖励结构的错误信念时,导致避免有益的选择.
- 之前的研究主要研究了静态环境中的学习陷.
研究的目的:
- 研究学习陷在动态环境中的影响,特别关注"变化失明" - - 不能注意到预测特征的变化.
- 检查学习陷如何影响环境规则变化时的适应性决策.
主要方法:
- 两个实验 (N=416) 涉及参与者决定从与收益或损失相关的类别中接近项目.
- 最初使用了一个二维类别规则,随后改变了其特征组成.
- 结果反取决于方法决策,模拟现实世界的场景.
主要成果:
- 很大一部分参与者采用了简化的一维规则,陷入了"学习陷".
- 这些参与者表现出"变化失明",无法检测或学习更新的二维规则.
- 提示改变规则的可能性并没有帮助陷入陷的个人,但改善了那些避免陷的人的学习.
结论:
- 学习陷加剧了动态环境中的决策缺陷,通过诱导"变化失明".
- 这些发现强调了不适应的策略的持久性,即使环境动态发生变化.
- 防止陷入学习陷的干预措施对于促进适应不断变化的环境的适应性至关重要.

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?

Cognitive Learning
223
Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.

Purposive Learning
102
E. C. Tolman emphasized the purposiveness of behavior — the idea that much of our behavior is goal-directed. For instance, employees who aim for a promotion work diligently to meet their targets. Tolman argued that when classical conditioning and operant conditioning occur, the organism acquires certain expectations. In classical conditioning, a child might fear a dog because they expect it to bite. In operant conditioning, a person might consistently work overtime because they expect a...

Introduction to Learning
341
Learning is the process of acquiring knowledge or skills through practice or experience, leading to long-lasting behavioral changes. This acquisition occurs through interaction with the environment and requires practice or experience. For instance, mastering a skill such as surfing requires considerable practice and experience, highlighting the essential role of repeated interactions with the environment in learning.

Social Traps
22.3K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Avoidance Learning and Learned Helplessness
1.7K
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
