概括
雌性的低社会地位影响了对细菌感染的免疫反应. 附属动物表现出改变的细胞因子分泌,这表明长期的健康风险,如慢性炎症和免疫衰老.
科学领域:
- 免疫学 免疫学 免疫学
- 神经内分泌学神经内分泌学
- 灵长类动物学 灵长类动物学
背景情况:
- 由于社会地位较低而导致的慢性社会压力与身体和精神疾病有关.
- 早期的生活压力加剧了与社会服从相关的健康风险.
- 了解免疫系统对社会压力的反应对于预测长期健康结果至关重要.
研究的目的:
- 研究低社会地位对 rhesus 子免疫标记的纵向影响.
- 在基线和免疫挑战条件下评估促炎和抗炎标记物的发育分泌模式.
- 检查社会地位,炎症和下丘脑-垂体-上腺 (HPA) 轴之间的关系.
主要方法:
- 在不同生命阶段 (婴儿期,青少年期,成年期) 的社会住所雌性 rhesus 子 (主导性与附属性) 中评估了基线和脂聚糖 (LPS) 刺激的细胞因子概况.
- 测量基底皮质醇水平以评估HPA轴活动.
- 分析了炎症标记物的纵向变化 (例如IL-6) 和细胞因子对LPS的反应.
主要成果:
- 基础炎症标志物和皮质醇水平并没有根据社会地位显著不同,尽管皮质醇随着年龄的增长而下降.
- 在成年后,下属子对LPS刺激表现出细胞因子特异性反应,IL-1β,IL-2和IL-10分泌量较高,但与主导子相比,IL-8分泌量较低.
- 这表明社会上下属个体的免疫失调.
结论:
- 在雌性中,终身的社会服从导致了针对免疫挑战的独特免疫反应.
- 这种改变的免疫反应可能会导致短期适应,但会增加慢性炎症和加速免疫衰老的长期风险.
- 社会地位显著调节免疫细胞功能以应对感染,这对健康差异有影响.

Social Scripts
10.3K
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

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...

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 Facilitation
36.6K
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 Loafing
39.7K
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 Exchange Theory
40.8K
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).
