Limits to Natural Selection01:38

Limits to Natural Selection

33.9K
Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.

Migration00:53

Migration

8.7K
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

Optimal Foraging00:48

Optimal Foraging

13.4K
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Timing and Consequences on Behavior01:08

Timing and Consequences on Behavior

324
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...

What is Behavior?00:54

What is Behavior?

9.9K
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

Cognitive Learning01:21

Cognitive Learning

957
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.
Tolman introduced the idea that behavior is influenced by...

科学领域:

  • 认知伦理学 认知伦理学
  • 动物行为 动物行为
  • 比较心理学比较心理学

背景情况:

  • 未来的规划和理解相互排斥的结果被认为是关键的认知能力.
  • 这种规划能力主要在人类身上进行了研究,对其在非人类动物中的存在产生了疑问.
  • 集团协调可以为集体规划提供另一种途径,即使个人规划有限.

研究的目的:

  • 研究亚洲大象 (Elephas maximus) 对相互排斥的结果的个人和集体规划能力.
  • 为了调整一个分叉管任务,以前用于儿童和猿人,用于大象.

主要方法:

  • 十二只亚洲大象单独和双双地使用修改的叉管任务进行了测试.
  • 这项任务涉及食物奖励从一个管子中掉下来,从两个开口之一出来.
  • 成功的衡量是以大象始终覆盖两个开口以确保奖励的能力来衡量.

主要成果:

  • 一个大象,南梅,学会了覆盖两个开口,取得成功明显超过机会 (61.5%).
  • 象对在获得奖励方面比个人更成功 (60.1%的试验).
  • 然而,完全协调 (涵盖两个开口) 并未通过对 (35.0%) 实现,南美回归只覆盖一个开口.

结论:

  • 这项研究的结果没有提供强有力的证据,证明了对大象相互排斥的结果的个人或集体规划.
  • 观察到的行为表明未来对大象认知和计划能力的研究有潜力.
  • 结果强调了评估非人类动物中高级认知功能的复杂性.
