まとめ
言語を学習する子供はエージェントの役割を優先し、「行為者」を「被行為者」よりも容易に予測する。このエージェント選好は言語間で一貫しており、予測には最小限のコンテキストしか必要としない。
科学分野:
- 心理言語学
- 発達心理学
- 計算言語学
背景:
- 言語理解には、増分予測と修正が含まれる。
- 言語間の成人は、患者よりもエージェントを優先する強い選好を示す。
- 不完全な入力で子供が意味役割を学習するかは不明なままである。
主な方法:
- タガログ語、英語、トルコ語の書き起こされた子供向け発話を利用した。
- 自然なデータで訓練された計算モデルを使用して、増分予測可能性を評価した。
- 各言語での実験データに対して計算モデルを検証した。
結論:
- エージェントの役割割り当ては、多様な言語間で子供にとってより簡単なタスクである。
- 患者の役割は文脈的に誘発され、言語固有の構造によって形成される。
- 発見は、言語獲得におけるエージェントの一般的な認知的選好を支持する。

Language Development

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
704
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.

Relationship with Parents: Attachment

Parent-child interactions lay the foundation for how we understand relationships throughout life. These interactions are not uniform across families; instead, they are shaped by a range of environmental, emotional, and behavioral factors unique to each caregiver-child dynamic. Social psychologists study these early relationships to understand how patterns formed in infancy influence social functioning and interpersonal behavior in adulthood.Attachment Theory and Early Relational ModelsJohn...

Components of Language
746
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.

Higher Mental Functions of the Brain: Language
3.4K
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...

Socioemotional Development during Infancy
423
Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.
