日常社會互動中的愛之重要性：正向共鳴累積生命意義感

Love in Everyday Social Interactions: Accumulating Meaning in Life through Positivity Resonance

正向共鳴理論將愛這種情緒定義為個體處在一種正向共鳴的狀態，雖然過去研究指出，愛、社會連結與生命意義感兩兩之間有顯著正向關聯，卻未有研究針對知覺正向共鳴是否會透過增加社會連結而對意義感產生影響之議題進行討論。本研究以一個三階段的研究設計，透過不同時序的資料來檢驗個體是否會因為在人際互動中反覆經驗到正向共鳴，而逐漸累積社會連結感，並能進而提升當下與日後的意義感。在研究方法上，於第一階段（N = 144），測量參與者在一般情況下的知覺正向共鳴特質、社會連結感以及生命意義感；在日記階段（N = 135），則請參與者一連七天在晚間進行日子重新建構法，蒐集其於日常人際互動中的知覺正向共鳴程度以及社會連結感與意義感；兩次追蹤階段分別是在日記階段結束的一個月後（N = 113）與兩個月後（N = 99）舉行，利用問卷再次測量其於社會連結與意義感之情況。研究結果顯示，橫斷與縱貫模型皆支持知覺正向共鳴會藉由增加知覺社會連結來提升意義感，且此效果在控制正向情緒或社會互動的頻率與時長等變項後仍然顯著。本研究結果說明高品質互動時與他人同步並相互關懷的集體正向情緒經驗，可以藉由緊密聯繫彼此從而通往有意義的人生。

Positivity resonance theory defines the emotion of love as a collective affective state, referred to as positivity resonance, characterized by shared positive affect, caring nonverbal synchrony, and biological synchrony. This study examined whether daily experiences of positivity resonance concurrently and prospectively influence meaning in life (MIL) through the increment of social connection. At time 1 (N = 144), perceived positivity resonance was measured at the trait level, along with MIL and social connection. Next, perceived positivity resonance was assessed at the episodic level via the Day Reconstruction Method across seven days (N = 135). Finally, two follow-up surveys were administered one (N = 113) and two months (N = 99) later. Participants again completed the questionnaires on MIL and social connection. Results suggest that social connection cross-sectionally and longitudinally mediates the links between perceived positivity resonance and MIL. These mediating effects remain statistically significant even after controlling for the individual-level positive and negative affect and amount of social interaction. These findings indicate that momentary experience of love while interacting with others may be an influential way to a meaningful life.
