Impact of Groups on Groups01:19

Impact of Groups on Groups

71
Social psychologists analyze how groups influence one another, shaping social structures and interactions through both cooperation and competition. These dynamics manifest in various ways, ranging from economic partnerships to intergroup conflicts that shape societal structures and perceptions.Cooperation and Competition in Intergroup RelationsIntergroup relationships vary across contexts, sometimes fostering cooperation and mutual benefit while at other times leading to conflict and...

In- and Out-Groups

41.3K
People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.

Infection01:20

Infection

9.5K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Defense Against Bacterial Pathogens01:31

Defense Against Bacterial Pathogens

1.7K
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Robbers Cave

14.5K
During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

12.9K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Area of Science:

  • Evolutionary Psychology
  • Social Psychology
  • Behavioral Ecology

Background:

  • Pathogen threat is a significant driver of intergroup behavior.
  • Existing research links pathogen threat to xenophobia and in-group favoritism.
  • The relationship between pathogen threat and in-group cooperation remains understudied.

Purpose of the Study:

  • To investigate the role of the behavioral immune system (BIS) in facilitating in-group cooperation.
  • To explore how BIS functions as a reactive mechanism against pathogen threat.
  • To propose that cooperative behaviors ensure social support for infected individuals.

Main Methods:

  • Review of existing literature on the behavioral immune system (BIS).
  • Analysis of studies connecting pathogen threat to social behaviors.
  • Theoretical framework development linking BIS to in-group cooperation.

Main Results:

  • The behavioral immune system (BIS) may promote cooperation with in-group members as a defense against pathogen threat.
  • Cooperative behaviors can be a strategy to secure social support when ill.
  • Evidence suggests BIS influences sociality beyond avoidance, extending to pro-social behaviors within groups.

Conclusions:

  • The behavioral immune system (BIS) likely plays a crucial role in fostering in-group cooperation.
  • Cooperation serves as a vital mechanism for managing infectious disease risks within social groups.
  • Further research is needed to fully elucidate the complex interplay between pathogen threat, BIS, and cooperative behaviors.
