Summary
Mice display rescue behaviors, including physical contact and grooming, toward unresponsive companions. The medial amygdala (MeA) in mice is crucial for recognizing unresponsiveness and initiating these prosocial actions.
Area of Science:
- Neuroscience
- Animal Behavior
- Social Cognition
Background:
- Human prosocial behaviors toward unresponsive individuals are well-documented.
- Reactions and neural underpinnings of animal responses to unresponsive conspecifics are largely unknown.
Purpose of the Study:
- To investigate animal responses to unresponsive conspecifics.
- To explore the neural mechanisms driving these behaviors.
Main Methods:
- Observation of mouse social behaviors toward unresponsive conspecifics.
- Neural activity analysis in the medial amygdala (MeA).
Main Results:
- Mice exhibit rescue-like behaviors, including intense physical contact and grooming, toward unresponsive individuals.
- The medial amygdala (MeA) encodes unresponsiveness and drives head-directed contact.
- Distinct neural representations in the MeA differentiate responses to unresponsive versus stressed individuals.
Conclusions:
- Mice exhibit prosocial behaviors toward unresponsive conspecifics.
- The medial amygdala (MeA) plays a key role in mediating these responses.
- This study provides insights into the neural basis of prosociality in animals.

02:34Empathy

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.

Voluntary behavior with the intent to help other people is called prosocial behavior. Why do people help other people? Is personal benefit such as feeling good about oneself the only reason people help one another?

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.

01:03Altruism

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.

00:56Attribution 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).

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.
