まとめ
青少年の排斥 (社会的排斥) は 脳の反応に独特な影響を及ぼし 排斥に対する感受性は 青春期と年齢とともに増加します 社会的包摂と排除の処理に関与する神経ネットワークも 発達過程で変化します
科学分野:
- 神経科学
- 発達心理学
- 社会心理学
背景:
- 社会的排斥は 青年の健康に影響を与える 強い感情的反応を引き起こします
- 青少年 の 発達 し て いる 脳 と 社会 の 優先 順位 は,疎外 の 影響 に 容易 に 影響 さ れる こと が あり ます.
研究 の 目的:
- 青少年の発達 (年齢と思春期) において,疎外感の神経メカニズムがどのように異なるかを調査する.
- 青少年における社会的包摂と排斥に対する脳の反応を検査するために 電気脳図 (EEG) を利用する.
主な方法:
- Lunchroom (ランチルーム) の脳波検査 (EEG) 作業の絵を描いた.
- イベント関連ポテンシャル (ERP) の幅度 (P1,N2,P3) と84人の青少年 (年齢10~14歳) のソース評価を分析した.
主要な成果:
- 異なるERPパターンが観察された:P1は包摂に対する感受性,N2は排除に対する感受性,P3は思春期によって調節された.
- 排除 (桃体,IFG) と包摂 (ACC,insula) のためのニューラルネットワークが特定されました.
- 排斥に対する感受性は,思春期 (P3) と年齢 (桃体,IFG) に伴い増加し,排斥に対する感受性は,年齢 (P1) に伴い減少した.
結論:
- オストラキズムと包摂に対する神経の敏感性は,青春期に発達し,年齢や思春期の状態に影響されます.
- 特定の脳領域と神経プロセスは 社会的排除と包摂に対する 異なる反応の基礎となっています
- この研究は,社会的経験の神経基盤を理解する上で発達変化の重要性を強調しています.

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...

This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...

Erikson's Theory on Socioemotional Development during Adolescence
353
Erik Erikson's fifth stage of psychosocial development, "identity versus role confusion," is crucial during adolescence (ages 12 to 18). In this stage, adolescents face the developmental task of forging a distinct personal identity, a process influenced by social, psychological, and biological changes typical of this period. Adolescents naturally explore different roles, behaviors, and ideologies as they navigate complex questions of self-concept, asking, "Who am I?" and "What is my place in...

Stereotypes, Prejudice, and Discrimination
91.4K
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...

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.
