概括
欧洲 (Barbus barbus) 表现出一致的个体行为,显示出表型的多样性. 这种行为变化表明,人口具有适应环境变化的能力.
科学领域:
- 动物行为 动物行为
- 生态生态学 生态生态学
- 鱼类学 鱼类学 鱼类学
背景情况:
- 现象型多样性增强了人口对环境变化的弹性.
- 欧洲 (Barbus barbus) 在自然环境中表现出个人的行为差异.
研究的目的:
- 为了确定反应-主动轴沿着欧洲巴贝尔的行为一致性.
- 评估个人行为是否可以在不同的实验条件下重复.
主要方法:
- 进行了三次连续的现场实验:开放场测试,镜像刺激测试和食行为测试.
- 每个实验都在每只鱼身上重复三次.
- 测量了行为特征,包括退出庇护所的延迟,庇护所内的活动和食成功.
主要成果:
- 观察到,在个体巴贝尔内部和个体巴贝尔之间,行为具有很高的变化.
- 退出庇护所的延迟,在庇护所度过的时间和食物消费显示出最高的重复性.
- 主要成分分析揭示了一致的行为表型,大多数人被归类为反应性 (羞怯,不那么探索,不那么社会).
结论:
- 尽管存在很高的变异性,但在欧洲鱼种群中存在一致的行为表型.
- 确定了反应性-主动性轴,表明存在相当大的表型多样性.
- 这种多样性表明,鱼种群可能具有适应能力,能够应对环境变化.

Fixed Action Patterns
15.8K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

What is Behavior?
8.9K
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.

Naturalistic Observations
15.4K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Attribution Theory
12.9K
Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).
