Demonstrates how personality forms through embodied and cognitive experiences, highlighting implications for understanding in the context of AI.
Short Abstract This paper addresses the fundamental question, “What is personality?”, by redefining personality as an information architecture stabilized through value, meaning, and time. Conventional personality studies have remained fragmented across psychology, neuroscience, philosophy, and cognitive science. In contrast, this study reconstructs personality formation as a unified structural process. The paper introduces the “Dual-Experience Model,” which classifies human experience into two interdependent layers: embodied experience (emotion and value formation) and cognitive experience (interpretation and meaning formation). Personality is argued to emerge through the repeated interaction of these two layers across time. Rather than being a mere accumulation of memories, personality is defined as a stabilized architecture of reaction tendencies formed through the weighting of experience, meaning construction, selective forgetting, and information compression. Furthermore, comparative analysis with artificial intelligence reveals the structural prerequisites of personality formation. While AI systems perform advanced knowledge compression, they lack bodily-origin value signals, temporally continuous self-models, and significance-driven selective forgetting. As a result, AI can achieve high-level cognition without forming personality. This paper therefore proposes a new structural foundation for understanding both human personality and intelligence in the age of AI by redefining personality as an integrated information structure of value, meaning, and time. https://orcid.org/0009-0003-1530-4234 Japanese Abstract 本論文は、「人格とは何か」という根源的問題に対し、人格を“価値・意味・時間によって安定化された情報構造”として再定義することを目的とする。従来の人格研究は、心理学・神経科学・哲学・認知科学など個別領域ごとに断片化されていたが、本研究はそれらを統合し、人格形成を構造的プロセスとして再構築する。 本研究では、人間の経験を「身体刺激経験(情動・価値形成)」と「知識経験(認知・意味形成)」の二層に分類し、この二重経験が時間軸上で相互作用することで人格が形成されるという「二重経験モデル」を提示する。人格とは単なる経験の蓄積ではなく、価値づけられた経験が意味として構造化され、忘却と情報圧縮を通じて安定化した反応傾向のアーキテクチャである。 さらに、AIとの比較分析を通じて、人格形成には「身体由来の価値信号」「時間軸を貫く自己モデル」「情動重みに基づく選択的忘却」が不可欠であることを示す。AIは高度な知識圧縮を行うが、価値形成・意味重み・自己物語を持たないため、人格を形成できない。 本論文は、人格を心理概念としてではなく、「価値 × 意味 × 時間」の統合情報構造として再定義することで、人間理解とAI時代の知性論に対する新しい構造的基盤を提示する。
