まとめ
社会経済的要因がコントロールされている場合,母乳育児は成人の知能に影響を与えないようです. 人形の使用や親の背景などの他の要因は,IQスコアのより重要な予測要因です.
科学分野:
- 子どもの発達 子供の発達 子供の発達
- コグニティブ・サイエンス コグニティブ・サイエンス
- 公衆衛生は公衆衛生である.
背景:
- これまでの研究では,母乳育児と子供のIQスコアの上昇との関連が示唆されています.
- しかし,この関連性は,母乳育児がしばしばより高い社会階級と結びついているため,社会経済的地位によって混乱しています.
- この研究は,母乳育児が社会経済的に有利でない集団における乳児の栄養と成人の知能を調査することを目的とした.
研究 の 目的:
- 幼児の栄養方法と成人の知能との関係を調べる.
- 社会階級,母親の年齢,兄弟姉妹の数などの混同変数を制御するために.
主な方法:
- イギリスのハーツフォードシャーで1920年から1930年の間に生まれた994人のコホートを追跡した.
- 保健訪問者によって乳児の栄養に関するデータが収集されました.
- 成人の知能は,AH4IQテストを使用して評価され,多変量分析を使用して有意な予測要因を特定しました.
主要な成果:
- 独占的に母乳を飲んだ参加者は,独占的にボトルで飲んだ参加者よりも少し高いIQスコアを示しました.
- しかし,多変量分析では,他の要因を考慮した後の乳幼児の栄養方法と成人の知能との間に有意な関連性がないことが明らかになった.
- 人形使用,兄妹の数,母親の出生年齢,父親の職業階級は,成人IQの独立した予測指標でした.
結論:
- 早期の授乳と後の知能の間の観察された関連は,母乳の栄養因子よりも,子供の社会的環境によってより影響を受ける可能性があります.
- 人形の使用,家族の大きさ,親の社会経済的な背景などの要因は,認知発達の重要な決定因子です.

00:55Parental Care
Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.
01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

01:29Three Developmental Domains
Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

01:25Piaget's Theory of Cognitive Development from Childhood into Adulthood
Jean Piaget's theory of cognitive development emphasizes the role of thinking in a child's learning process, suggesting that children are naturally curious about their environment. His approach to development is discontinuous, proposing that cognitive abilities progress through distinct stages, each with unique characteristics. Central to Piaget's theory is schemata—mental structures that allow individuals to understand and interpret the world.

01:14Piaget's Stage 1 of Cognitive Development
The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.

01:30Cognitive Development During Adulthood
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...
