Genetic Drift03:33

Genetic Drift

39.4K
Natural selection—probably the most well-known evolutionary mechanism—increases the prevalence of traits that enhance survival and reproduction. However, evolution does not merely propagate favorable traits, nor does it always benefit populations.

Conservation of Declining Populations02:07

Conservation of Declining Populations

9.6K
Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

The Fossil Record02:56

The Fossil Record

25.0K
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...

Generalization, Discrimination, and Extinction01:24

Generalization, Discrimination, and Extinction

425
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

Ecological Disturbance02:26

Ecological Disturbance

17.0K
An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.

Threats to Biodiversity01:50

Threats to Biodiversity

22.1K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

科学领域:

  • 认知心理学 认知心理学
  • 行为神经科学 行为神经科学
  • 学习和记忆的学习和记忆

背景情况:

  • 灭绝是协会学习中的一个关键过程,但它对暗示表征的影响仍在争论中.
  • 了解灭绝如何改变内部表征对于解释更新和复发等现象至关重要.

研究的目的:

  • 为了调查灭绝是否改变了学习的提示的表示性质.
  • 检查这种表示变化如何影响配置线索和抑制控制.

主要方法:

  • 三组学习了负模式 (X+/Y+/XY-) 和正模式 (Z+/W+/ZW++) 的歧视.
  • 经过训练后,小组在相同的 (Ext A) 或不同的环境 (Ext B) 中经历了暗示符X (或Z) 的灭绝,或者没有受到灭绝.
  • 所有组都在原始培训环境中进行了测试,以评估泛化和更新.

主要成果:

  • 没有灭绝的组表现出完整的负面模式.
  • 在同一个背景下灭绝 (Ext A) 减少了对灭绝的提示 (X) 的抑制,并且矛盾地增加了对配置提示 (XY) 的响应,扭转了歧视.
  • 在不同的背景下 (Ext B) 的灭绝导致了对X和X/XY歧视的反应的更新.

结论:

  • 灭绝似乎在灭绝的标志 (X) 中引起了代表性的变化.
  • 这些变化破坏了依赖于X的原始表示的配置表示 (XY).
  • 这些发现支持了结合式学习的理论,这些理论包含了灭绝期间的表示变化.
