- 动物行为 动物行为
背景情况:
- 群众的运动是跨物种和规模的常见现象,从昆虫到哺乳动物和运动细胞.
- 陆地动物在通过狭窄的开口撤离时经常表现出颗粒状物质的行为,导致堵塞和效率降低.
- 了解不同物种的疏散动态对于预测紧急情况中的人群行为至关重要.
研究的目的:
- 为了研究宏观的疏散行为,当被迫通过狭窄的通道时,水生生物 (虹鱼) 的疏散行为.

01:06Fixed Action Patterns
16.1K
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.

01:04Social Facilitation
32.0K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

The famous and controversial Stanford Prison Experiment, conducted by social psychologist Philip Zimbardo and his colleagues at Stanford University, demonstrated the power of social roles, social norms, and scripts.

02:06Social Exchange Theory
34.6K
We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

00:54What is Behavior?
9.0K
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.
