Language

894
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.
Corballis and Suddendorf (2007) and Tomasello and Rakoczy (2003) highlight the role of language in...

Line Loss01:10

Line Loss

517
The different configurations of source-load connections include wye (star) and delta connections. The relationship between line and phase voltages and currents varies depending on the configuration. When the source is supplying power, it is transmitted through the wires to the load, and during this transmission, some power is absorbed by the wires, leading to line loss.
Line loss impacts power delivery efficiency in a balanced three-phase circuit. The symmetry in such a circuit simplifies the...

Weighted Mean

While taking the arithmetic, geometric, or harmonic mean of a sample data set, equal importance is assigned to all the data points. However, all the values may not always be equally important in some data sets. An intrinsic bias might make it more important to give more weightage to specific values over others.
For example, consider the number of goals scored in the matches of a tournament. While computing the average number of goals scored in the tournament, it may be more important to...

Components of Language01:24

Components of Language

776
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.

Language Development01:22

Language Development

872
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 Cognition01:27

Language and Cognition

730
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.

まとめ

大規模言語モデル（LLM）AIチャットボットは、パーソナライズされた体重管理コーチングに有望である。修正後、AIメッセージは人間のコーチと同等の有用性を示し、人間が書いたものと間違われることが多かった。

科学分野:

  • 行動科学
  • 人工知能
  • ヘルスコーチング

背景:

  • 自動化された体重管理コーチングメッセージは、繰り返しが多く、人間のコーチングよりも効果が低い場合がある。
  • 大規模言語モデル（LLM）AIチャットボットは、パーソナライズされた斬新なコーチングメッセージの可能性を提供する。
  • LLMベースの体重管理コーチングの実行可能性と許容可能性は、依然として十分に研究されていない。

主な方法:

  • BMIが27 kg/m²以上の成人87名が体重減少トライアルに参加した。
  • 参加者は、人間が書いたコーチングメッセージとChatGPTが生成したコーチングメッセージの有用性を5点リッカート尺度で評価した。
  • メッセージの修正を伴う2つのフェーズで、質的なフィードバックとAIメッセージの同定が収集された。

結論:

  • LLM AIは、効果的な体重管理コーチングメッセージを作成するための予備的な実行可能性を示している。
  • AI生成メッセージは、改良後、人間が書いたコンテンツに匹敵する有用性とパーソナライズされたものとして認識される可能性がある。
  • AIコーチングの定型的でデータ中心的な側面に対処するためには、さらなる改善が必要である。
