まとめ
科学者は脳が他の動物を 宇宙で追跡する方法を発見しました 観察者のニューロンは デモンストレーターバットの位置を表し 社会的空間的認知を助長しました
科学分野:
- 神経科学
- 認知科学
- 動物 の 行動
背景:
- 社会的な動物は 生存と相互作用のために 同種の空間的位置に関する知識を必要とします
- 他人の脳内の位置を 表現する神経機構は ほとんど解明されていません
研究 の 目的:
- 他人の空間的位置を 脳がどう表現するかを調べる
- 社会空間的認知に関与する特定のニューロン集団を特定する.
主な方法:
- コウモリを使って 空間観察学習の課題を設計しました
- ヒッポカンパの背面CA1 (Dorsal CA1) ニューロンの活動は,デモンストレーターコウモリを模倣した観察コウモリで記録された.
主要な成果:
- 海馬の神経細胞のサブポピュレーションは 演習蝙蝠の位置を 偏心座標で表した.
- この"社会的場所の細胞"の およそ半分は 観察者のバット自身の位置を コード化しています
- デモンストレーターバットの表現は,自己運動や軌道の計画とは異なります.
- 非生命体を表すニューロンは デモンストレーターバットと比べて 異なる表現特性を示しました
結論:
- ヒポキャンパスのCA1ニューロンは 社会空間的認知において重要な役割を果たします
- 脳は特定のニューロンの集合体を使って 同種の場所を追跡します
- この研究は 他人の空間的存在を理解する 神経的基盤の洞察を提供します

Social Proof
32.4K
Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Social Scripts
10.3K
People tend to know what behavior is expected of them in specific, familiar settings. A script is a person’s knowledge about the sequence of events expected in a specific setting (Schank & Abelson, 1977). Essentially, scripts are a particular kind of schema, one containing default values for the features within an event. In the restaurant example, the script's features include the props (e.g., tables, menu, food, and money), the roles to be played (e.g., customer and waiter),...

Social Traps
26.9K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Social Facilitation
36.6K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Social Loafing
39.7K
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

Social Exchange Theory
40.8K
We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).
