Aggression

30.5K
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

Group Design

10.9K
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...

Impact of Groups on Individuals

405
Groups play a fundamental role in shaping individual behavior, as they establish norms that guide interactions and decision-making. Social psychology examines how individuals conform to group expectations, often adjusting their attitudes and actions to align with group norms. These norms can be formal, such as workplace policies, or informal, such as unspoken social expectations within a fraternity.Conformity and Social InfluenceConformity arises when individuals modify their behaviors or...

Impact of Individuals on a Group

371
In social psychology, the interplay between individuals and groups is a central concern, particularly regarding how individual actions and characteristics influence group processes and outcomes. While much research emphasizes the group's power in shaping individual behavior, it is equally significant to understand how individuals contribute to the functioning, development, and success of groups.Individual Roles in Group Productivity and Decision-MakingIndividuals are not passive participants in...

科学分野:

  • 社会心理学
  • 政治心理学
  • 社会学

背景:

  • 集団的暴力は重大な社会問題である。
  • 集団的暴力に対する支持に影響を与える個人の心理的要因は、十分に研究されていない。
  • 既存の対人暴力に関する研究は、集団的暴力には完全には適用されない可能性がある。

研究 の 目的:

  • 集団的暴力信念における個人差を測定するための、新しい多次元尺度の開発と検証。
  • 集団的暴力の正当化の構造の調査。
  • 標的別に集団的暴力のタイプを区別すること。

主な方法:

  • レバノン、シリア、トルコ出身の5つのサンプル（N=3758）を用いた4つの研究を実施した。
  • 2次元集団的暴力信念尺度（CVBS：2D）を開発・検証した。
  • 多様な文化的文脈で尺度検証技術を利用した。

主要な成果:

  • 集団的暴力の正当化は、その強度ではなく、行為の標的によって構造化されていることが判明した。
  • 拡散型集団的暴力（アウトグループメンバーを標的とする）と上向き集団的暴力（アウトグループリーダーを標的とする）を区別するCVBS：2次元尺度を開発した。
  • 複数のサンプルと文脈で尺度を検証した。

結論:

  • 本研究は、集団的暴力信念を測定するための新規かつ検証済みの手段を提供する。
  • 拡散型と上向き型の2つの異なる集団的暴力信念の次元を特定した。
  • 集団的暴力に対する支持を理解する上で、暴力の標的を考慮することの重要性を強調する。
