概括
小鼠表现出救援行为, 包括对不响应的同伴进行身体接触和理. 小鼠中枢桃体 (MeA) 对于识别不响应和启动这些亲社会行为至关重要.
科学领域:
- 神经科学
- 动物的行为
- 社会认知
背景情况:
- 人们对不响应的个体的亲社会行为已经得到了很好的记录.
- 动物对不响应同物种的反应和神经基础在很大程度上是未知的.
研究的目的:
- 研究动物对不反应的同类动物的反应.
- 探索驱动这些行为的神经机制.
主要方法:
- 对没有反应的同类动物的小鼠社会行为的观察.
- 中枢桃体 (MeA) 中的神经活动分析.
主要成果:
- 小鼠表现出类似于救援的行为, 包括强烈的身体接触和理,

Empathy

Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.

Altruism

Altruistic behaviors are “unselfish” behaviors—those that help another individual at the expense of the individual carrying out the behavior. Despite the negative consequences for the altruistic animal, these behaviors are thought to have evolved for several reasons.

Attribution Theory

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).

Bystander Effect

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.
