Abstract

This study defines human pleasure not merely as a biological reward response or ambiguous emotional preference, but as a signal outcome occurring within the 'Pleasure Circuit' when an individual's unique value criterion(𝑉) structurally matches an external stimulus(𝑋). To elucidate this, We propose the RASEC model, composed of five independent dimensions: Reception (R), Action (A), Situation (S), Emotion (E), and Cognition (C). The model quantifies the mechanism of pleasure generation using a linear combination function: 𝑃𝑛𝑒𝑑=Ξ£π‘Š β‹…(𝑉⋅𝑋). Here, 𝑉 denotes the individual's directionality (preference criterion), π‘Š represents the sensitivity weight, and 𝑋 indicates the attribute value of the external stimulus. Notably, unlike existing methods that classify subjects first, this study adopts a methodology that numerically profiles the external stimulus (𝑋) based on RASEC criteria first, and then reverse-engineers the characteristics of an individual's pleasure circuit by observing the deviation in individual responses to it. By providing an analytical framework that converts abstract emotional stimuli into quantitative vectors, this study aims to contribute to the theoretical expansion of Differential Psychology as well as the development of AI persona design and emotion prediction algorithms. λ³Έ μ—°κ΅¬λŠ” μΈκ°„μ˜ 쾌감(Pleasure)을 λ‹¨μˆœν•œ 생물학적 보상 λ°˜μ‘μ΄λ‚˜ λͺ¨ν˜Έν•œ 감정적 μ„ ν˜Έκ°€ μ•„λ‹Œ, β€˜μΎŒκ° 회둜(Pleasure Circuit)’ λ‚΄μ—μ„œ 개인의 κ³ μœ ν•œ κ°€μΉ˜ κΈ°μ€€(𝑉)κ³Ό μ™ΈλΆ€ 자극(𝑋)이 ꡬ쑰적으둜 일치(Match)ν•  λ•Œ λ°œμƒν•˜λŠ” μ‹ ν˜Έμ  결과둜 μ •μ˜ν•œλ‹€. 이λ₯Ό 규λͺ…ν•˜κΈ° μœ„ν•΄ 수용(R), ν–‰μœ„(A), 상황(S), μ •μ„œ(E), 인지(C)의 5κ°€μ§€ 독립 μ°¨μ›μœΌλ‘œ κ΅¬μ„±λœ RASEC λͺ¨λΈμ„ μ œμ•ˆν•œλ‹€. λ³Έ λͺ¨λΈμ€ 쾌감 λ°œμƒ λ©”μ»€λ‹ˆμ¦˜μ„ 𝑃𝑛𝑒𝑑=Ξ£π‘Š β‹…(𝑉⋅𝑋)λΌλŠ” μ„ ν˜• κ²°ν•© ν•¨μˆ˜λ‘œ μ •λŸ‰ν™”ν•œλ‹€. μ—¬κΈ°μ„œ 𝑉 λŠ” 개인의 λ°©ν–₯μ„±(μ„ ν˜Έ κΈ°μ€€), π‘Š λŠ” 민감도 κ°€μ€‘μΉ˜, 𝑋 λŠ” μ™ΈλΆ€ 자극의 속성값을 μ˜λ―Έν•œλ‹€. 특히 λ³Έ μ—°κ΅¬λŠ” ν”Όν—˜μžλ₯Ό λ¨Όμ € λΆ„λ₯˜ν•˜λŠ” κΈ°μ‘΄ 방식과 달리, μ™ΈλΆ€ 자극(𝑋 )을 RASEC 기쀀에 따라 λ¨Όμ € 수치적으둜 ν”„λ‘œνŒŒμΌλ§(Profiling)ν•œ ν›„, 이에 λŒ€ν•œ κ°œμΈλ³„ λ°˜μ‘ 편차λ₯Ό κ΄€μ°°ν•¨μœΌλ‘œμ¨ 개인의 쾌감 회둜 νŠΉμ„±μ„ μ—­μΆ”μ ν•˜λŠ” 방법둠을 μ±„νƒν•œλ‹€. 이 μ—°κ΅¬λŠ” 좔상적인 μ •μ„œ μžκ·Ήμ„ μ •λŸ‰μ  λ²‘ν„°λ‘œ λ³€ν™˜ν•˜λŠ” 뢄석 ν”„λ ˆμž„μ›Œν¬λ₯Ό μ œκ³΅ν•¨μœΌλ‘œμ¨, 개인차 심리학(Differential Psychology)의 이둠적 ν™•μž₯뿐만 μ•„λ‹ˆλΌ 인곡지λŠ₯(AI) 페λ₯΄μ†Œλ‚˜ 섀계 및 μ •μ„œ 예츑 μ•Œκ³ λ¦¬μ¦˜ κ°œλ°œμ— κΈ°μ—¬ν•˜λŠ” 것을 λͺ©μ μœΌλ‘œ ν•œλ‹€.
