Stereotypes, Prejudice, and Discrimination

Stereotypes, Prejudice, and Discrimination

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Relationship Formation

Relationship Formation

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Stereotype Content Model

Stereotype Content Model

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Meiosis II

Meiosis II

Meiosis II entails cell division and segregation of the sister chromatids, resulting in the production of four unique haploid gametes. The steps for meiosis II are similar to mitosis, except that meiosis II occurs in haploid cells, whereas mitosis occurs in diploid cells.
The timing and cell division patterns of meiosis differ between males and females. In male meiosis, the centrosomes are part of the formation of the meiotic spindle. However, in oocytes, including that of humans, Drosophila,...

Law of Segregation

Law of Segregation

When crossing pea plants, Mendel noticed that one of the parental traits would sometimes disappear in the first generation of offspring, called the F1 generation, and could reappear in the next generation (F2). He concluded that one of the traits must be dominant over the other, thereby causing masking of one trait in the F1 generation. When he crossed the F1 plants, he found that 75% of the offspring in the F2 generation had the dominant phenotype, while 25% had the recessive phenotype.

Two-Way ANOVA

Two-Way ANOVA

The two-way ANOVA is an extension of the one-way ANOVA. It is a statistical test performed on three or more samples categorized by two factors - a row factor and a column factor. Ronald Fischer mentioned it in 1925 in his book 'Statistical Methods for Researchers.'
The two-way ANOVA analysis initially begins by stating the null hypothesis that there is an interaction effect between the two factors of a dataset. This effect can be visualized using line segments formed by joining the...

Summary

This summary is machine-generated.

Introducing an aging effect into the Schelling model of residential segregation reveals that agents develop emotional attachments, leading to stable segregated neighborhoods even with high tolerance. This aging mechanism alters the model dynamics, creating a glassy-like state.

Social Sciences
Computational Social Science
Agent-Based Modeling

Background:

The Schelling model is a foundational agent-based model explaining residential segregation.
Existing models often show a sharp phase transition between mixed and segregated states.
Citizen tolerance for mixed neighborhoods does not always prevent segregation.

Purpose of the Study:

To investigate the impact of an aging effect on the Schelling model dynamics.
To explore how emotional attachment to a location influences residential segregation.
To analyze changes in segregation patterns and agent satisfaction.

Main Methods:

A constrained, noisy version of the Schelling model was utilized.
An aging mechanism was introduced, inversely proportional to satisfaction duration.
Agents move to satisfying vacancies, with movement probability affected by satisfaction time.

Main Results:

The distinct phase transition between mixed and segregated states was eliminated.
Segregated states with high agent satisfaction persist even with high tolerance.
The new segregated phase exhibits slow, power-law coarsening dynamics, resembling glassy behavior.

Conclusions:

Agent emotional attachment, simulated by aging, stabilizes segregated neighborhoods.
The aging mechanism fundamentally alters Schelling model dynamics and outcomes.
The model now demonstrates glassy-like dynamics in segregated states.
