概括
城市化可能并不总是提高动物的认知能力. 一些物种利用现有的认知技能在城市中壮成长,而不是面对推动进化的新挑战.
科学领域:
- 生态生态学 生态生态学
- 动物行为 动物行为
- 进化生物学 进化生物学
背景情况:
- 城市化带来了新的环境条件,通常被认为会提高动物的认知能力.
- 然而,证实城市环境具有认知要求的经验证据有限.
研究的目的:
- 挑战城市环境必然增强动物认知能力的共识.
- 提出一些物种可能是预先适应的 ("exapted"),以利用现有的认知工具利用城市的利基.
主要方法:
- 对现有的假设和关于动物认知和城市化数据的概念分析.
- 在比较城市和非城市人口的研究中识别潜在的偏见.
主要成果:
- 城市环境可能为某些大脑物种提供"容易"的可利用.
- 现有的认知能力,而不是新的选择性压力,可能会促进城市的持久性.
结论:
- 物种认知可能有助于城市生存,但不意味着由于城市化而导致的认知增强.
- 研究人员在研究认知特征进化时,应该确定新的环境方面,而不仅仅是城市化本身.

Ecological Niches
24.6K
All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

Schemas
12.0K
A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Natural Selection and Adaptation
457
Natural selection, a fundamental concept in evolutionary biology, is the mechanism by which evolution is driven, favoring organisms that are best adapted to their environments. This process enhances their chances of survival and reproduction. Adaptation, a key outcome of this process, involves genetic modifications that optimize an organism's functionality under specific environmental challenges, such as extreme cold or thinner air at high altitudes.

Cognitive Learning
672
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.

The Nativist Approach
149
The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to...

Cognitivism
1.7K
Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...
