科学分野:
- 認知発達
- 社会心理学
- 発達心理学
背景:
- 人間の信念形成は、個人の推論と社会集団の力学の両方によって影響を受ける。
- グループ所属が幼児期の信念発達にどのように影響するかを理解することは非常に重要である。
研究 の 目的:
- 4〜6歳児の信念形成と修正におけるグループ所属の影響を調査する。
- 社会集団への所属が子供たちの証拠評価にどのように影響するかを調べる。
主な方法:
- 262人の4〜6歳児が参加した3つの研究。
- 子供たちは、内集団またはグループなしのいずれかに割り当てられた。
- 子供たちは、グループの信念に関する結論を形成するために証拠を評価した。
主要な成果:
- グループ所属の子供たちは、内集団の信念を支持し、反対の証拠を却下することで、証拠評価に偏りを示した。
- グループに所属する子供たちは、不正確なグループの信念を採用する可能性が高かった。
- グループ所属のない子供たちは、合理的に証拠を評価し、正確な結論に達した。
結論:
- グループ所属は、子供たちの証拠基準と信念の正確性を著しく変化させる。

Confirmation Biases
7.6K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis.

Group Design
10.1K
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...
