概括
暴露于人工救援呼叫的幼显示出生长和应激反应的改变. 连续通话改善了增长,而间歇性通话导致了补偿性增长,影响了长期的弹性.
科学领域:
- 动物行为 动物行为
- 发育生物学是发展生物学.
- 动物福利 动物福利
背景情况:
- 社会信号影响年轻动物的发育和情绪状态.
- 年轻 (Gallus gallus domesticus) 的紧急呼叫可能表明类似焦虑或类似抑郁的状态.
- 早期的生活经历塑造了长期的压力感知和弹性.
研究的目的:
- 调查人工救援呼叫模式对小生长和发育的影响.
- 确定紧急呼叫特征 (连续或间歇) 是否会对情绪状态和成长轨迹产生不同的影响.
- 评估早期听觉刺激对后期生活中的压力感知和恢复能力的持久影响.
主要方法:
- 年龄在4-7天的 (Gallus gallus domesticus) 被暴露在模仿连续或间歇性紧急呼叫的人工听觉刺激中.
- 对照组没有收到任何特定的听觉刺激,只有噪音的组接触到类似的噪音水平.
- 监测了生长参数,并评估了对晚年社会隔离压力因素 (温度,呼叫率) 的反应.
主要成果:

Types of Stressors
664
A stressor is any event, condition, or stimulus that triggers stress and causes a physical or psychological response in the body. Stressors can be categorized into three main types: catastrophes; significant life changes; and daily hassles, including social stress. Each can be detrimental to physical and mental well-being.
Catastrophes
Catastrophes refer to large-scale, unpredictable events that create overwhelming stress and a sense of threat. Examples include natural disasters like...

Social Loafing
38.9K
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

Social Facilitation
36.0K
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.

Social Proof

Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Social Scripts
10.2K
People tend to know what behavior is expected of them in specific, familiar settings. A script is a person’s knowledge about the sequence of events expected in a specific setting (Schank & Abelson, 1977). Essentially, scripts are a particular kind of schema, one containing default values for the features within an event. In the restaurant example, the script's features include the props (e.g., tables, menu, food, and money), the roles to be played (e.g., customer and waiter),...

Social Traps
26.3K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...
