まとめ

幼児の語彙はどんどん豊かになり,新しい言葉の習得は主に既に知っている言葉と結びつきます. 言語の発達には環境の言葉のつながりも少ない役割を果たします

科学分野:

子どもの言語習得
発達心理学
コンピュータ言語学

背景:

言語学習には環境要因が不可欠です.
個々の子供の既存の語彙は語彙の発達に大きく影響を与えます.
横断的な研究では発達経路の捉え方には限界があります

研究の目的:

小児の語彙習得に音声学的接続性がどのように影響するかを調査する.
縦断データを使って単語の学習における個々の違いを検証する.
熟知語の相対的な影響と周囲の言葉の相対的な影響を定義する.

主な方法:

ノルウェー語を学ぶ子どもたちの縦断的な語彙データを活用した.
新しい単語と子供の既存の語彙の音声学的関連性を分析した.
新しい言葉と子供の言語環境の音声学的関連性を評価する

主要な成果:

初期の語彙の成長は"豊かになる"というパターンです.
単語学習は既知の単語との音声学的リンクによって強く予測されます
音声学的なリンクは環境の言葉には少ないが,それでも重要な影響がある.

結論:

縦断的な分析は,子供の既存の語彙が,さらなる語彙の発展の主要な原動力であることを明らかにします.
有名な単語との音声的なつながりは, "豊かになる-豊かになる"の語彙の拡大の鍵です.
これらの個別の違いを理解することは言語の発達を理解するために不可欠です

Language Development

444

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Language and Cognition

438

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Longitudinal Research

12.4K

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Higher Mental Functions of the Brain: Language

1.0K

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Components of Language

388

Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.
