まとめ
GPT-4oのような大型言語モデル (LLM) は,特に自己指導のタスクでは,子供に似たプライベートスピーチを生成することができます. テーマタイプではなく,タスクの性質が,この言語パターンに大きく影響します.
科学分野:
- コグニティブ・サイエンス コグニティブ・サイエンス
- 人工知能 (AI) とは,人工知能 (AI) のことです.
- コンピュータ言語学 コンピュータ言語学
背景:
- プライベートスピーチは,一般的に子供に見られるもので,自己調節や問題解決などの認知機能に役立つ.
- 大型言語モデル (LLM) は,人間のようなテキストを生成する上でますます洗練されており,その認知能力の調査を促しています.
- LLMで生成されたプライベートスピーチの理解は,人工知能とコンピューティング意識の洞察を提供することができます.
研究 の 目的:
- 非推論LLM (GPT-4o) のプライベートスピーチを生成する能力を調査する.
- LLMで生成されたプライベートスピーチと人間のプライベートスピーチの類似性を評価する.
- LLMのプライベートスピーチの内容に影響を与える要因を探求する.
主な方法:
- 推論をしないLLM (GPT-4o) は,テキストプロンプトを使用して,シミュレートされた単一ブロック構築シナリオに配置されました.
- LLMの自己指向的な発言は,子供のプライベートスピーチを分類するための確立された意味論的枠組みを使用して引き出され,分類されました.
- LLMのプライベートスピーチカテゴリーの分布は,ブロック構築研究の2つの人間のベンチマークと比較されました.
主要な成果:
- GPT-4oのプライベート・スピーチ・プロフィールは,古典的ベンチマークとほとんど似ていない (r = 0.01) が,最近のベンチマークと非常に似ていた (r = 0.93).
- この差異は,対象 (LLM vs. 子供) ではなく,課題の性質 (目標指向対自己決定的遊び) に起因した.
- GPT-3.5-Turbo-instructによる探査研究でも,シリアルリコールタスクにおける偶発的なプライベートスピーチが明らかになった.
結論:
- タスクの特徴,特に自己決定の度合いや脚立は,LLMのプライベートスピーチの内容を大きく左右します.
- LLMは,特定の条件下で人間のパターンを反映するプライベートスピーチ生成の能力を実証しています.
- この研究は,プライベートスピーチのLLM複製と,計算意識に対するその意味を研究するための道を開きます.

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...

Social Foundations of Self II: The Generalized Other

According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group...

Language and Cognition
829
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.

Components of Language
837
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.

Observational Learning
1.0K
Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...

Language

Language is a unique communication system that uses words and systematic rules to organize and transmit information. Unlike other forms of communication, which may involve postures, movements, odors, or vocalizations, language relies on symbols and grammar. This makes human communication distinct from that of other species, who also communicate but do not use language in the same way humans do.
