Social Foundations of Self II: The Generalized Other

206
According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group...

Bullying

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

Group Design

The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

Robbers Cave

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...

The Scientific Method

Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.

Area of Science:

  • Child Psychology
  • Educational Psychology
  • Public Health

Background:

  • School-based violence prevention programs are crucial for fostering positive social environments.
  • Early intervention can significantly impact children's social competence and aggressive behaviors.
  • Evaluating large-scale universal prevention trials presents unique challenges.

Purpose of the Study:

  • To evaluate the effectiveness of the universal, elementary school-based PeaceBuilders violence prevention program.
  • To assess the program's impact on children's social competence and aggressive behaviors.
  • To determine the long-term effects of the intervention over two school years.

Main Methods:

  • Eight matched elementary schools (over 4,000 students, Grades K-5) were randomly assigned to immediate (PBI) or delayed (PBD) intervention groups.
  • Hierarchical linear modeling was employed to analyze assessment data collected in fall and spring over two consecutive school years.
  • Teacher-rated social competence, child-reported peace-building behavior, and aggressive behavior were primary outcome measures.

Main Results:

  • In Year 1, PBI schools showed significant gains in social competence (Grades K-2) and peace-building behavior (Grades K-5), alongside reductions in aggression (Grades 3-5).
  • Differential effects were noted for aggression and prosocial behavior in Year 1.
  • Most positive effects, including increased child prosocial behavior (Grades K-2), were maintained in Year 2 for PBI schools.

Conclusions:

  • The PeaceBuilders program demonstrates efficacy as a universal, school-based intervention for enhancing social competence and reducing aggression in elementary students.
  • The findings support the long-term benefits of early, school-wide violence prevention strategies.
  • The study highlights the importance of robust evaluation methods for large-scale prevention initiatives.
