まとめ
児童の暴力への曝露は,自律神経系の反応によって影響を受け,男の子と女の子の攻撃性に異なった影響を及ぼします. 特定の生理学的反応が,暴力への曝露と攻撃性のサブタイプとの関係を緩和します.
科学分野:
- 発達心理学の心理学について
- 神経科学は神経科学である.
- 児童のトラウマに関する研究
背景:
- 児童のコミュニティ暴力 (CVE) への曝露は,後の攻撃性に関連しています.
- 特定の攻撃的形態と機能に対するCVEの影響,および自律神経系 (ANS) の反応性の緩和作用については,さらなる調査が必要である.
研究 の 目的:
- 攻撃性のサブタイプに対する5年間の恐怖に対するCVEとANSの反応性の共同の影響を調べる.
- CVE,ANSの反応性,および攻撃性の発達を結びつけるジェンダー特有の経路を調査する.
主な方法:
- 197人の多様な子ども (7歳) を対象とした長期的研究.
- 地域社会での暴力への曝露 (CVE) と自律神経系 (ANS) の反応性 (交感神経系 (SNS) とパラ交感神経系 (PNS)) を評価した.
- 測定された身体的および関係性の攻撃性,および積極的および反応的な攻撃性のサブタイプ.
主要な成果:
- CVEは,パラシンパティック神経系 (PNS) 阻害の少年におけるより大きな反応的身体的攻撃性を予測した.
- CVEは,交感神経系 (SNS) 阻害の女の子において,より積極的な関係性攻撃性を予測した.
- 相互作用により,異なる経路が明らかになった:CVEは,SNS / PNSの共同活性化による男の子の積極的な関係性攻撃と,SNSの相互活性化による女の子の反応的な身体的攻撃に関連している.
結論:
- 明確なジェンダー特有の経路は,自律神経系の反応によって媒介される,児童の暴力への曝露と攻撃性を結びつける.
- 調査結果は,環境要因 (CVE) と生理学的要因 (ANS反応性) を両方に対処する介入の必要性を強調しています.
- ターゲットを絞り,文脈に敏感な介入は,暴力にさらされた子どもたちの攻撃性を軽減するために不可欠です.

Aggression

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...

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...

Social behavior is a complex phenomenon that arises from the interaction between biological predispositions and environmental influences. This intricate interplay shapes how individuals think, feel, and act in various social contexts. Understanding these mechanisms requires insights from psychology, neuroscience, genetics, and evolutionary theory.Environmental Influences on Social BehaviorEnvironmental factors, including temperature, odors, and visual stimuli, play a crucial role in shaping...

Disorders of the Autonomic Nervous System
1.6K
The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.

Automatic Processing and Automatic Social Behavior
274
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Conduct Disorder
636
Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
