초록

본 연구는 낭만적 관계에서 발생하는 외도 의도를 예측하는 성격적 특성과 상황적 특성을 확인하고, 둘 사이의 상호작용을 살펴보았다. 연구 1에서는 외도 의도에 대해 나르시시즘과 성별이 어떤 영향을 미치는지 확인하였다. 이를 위해 기혼 남녀 116명을 대상으로 나르시시즘을 측정하고, 결혼 생활 중 우연하게 발생한 외도 기회를 묘사한 시나리오를 이용하여 외도 의도를 측정하였다. 연구 결과, 남성이 여성에 비해서 더 높은 외도 의도를 가지고 있었고, 나르시시즘이 높을수록 더 많은 외도 의도를 가지고 있었다. 하지만 두 변인 간의 상호작용효과는 발견되지 않았다. 즉, 나르시시즘은 성별의 효과와는 독립적으로 외도 의도에 영향을 미쳤다. 연구 2에서는 외도 의도에 대한 상황적 특성의 영향력을 확인하고, 외도 의도에 대해 나르시시즘과 상황적 특성 간의 상호작용적 측면을 살펴보았다. 이를 위해 낭만적 관계 중에 있지 않은 남자 대학생 143명을 대상으로 나르시시즘을 측정한 뒤, 투자 모델 내 요인(투자 정도, 대안의 질)에 의거하여 조작된 시나리오를 통해 외도 의도를 측정하였다. 먼저 외도 의도는 조작된 상황적 특성에 따라 차이가 나타났는데, 구체적으로 투자 정도가 낮거나 대안의 질의 수준이 높은 경우에 외도 의도가 높게 나타났다. 또한 나르시시즘은 현재 낭만적 관계에 대한 투자 정도와 대안으로 다가온 외도 대상의 가치가 모두 높거나 모두 낮은 경우에만 외도 의도와 정적 관계를 보였다. 본 연구는 나르시시즘이라는 성격적 특성과 투자 정도와 대안의 질의 높고 낮음이라는 상황적 특성이 외도 의도에 미치는 영향력을 각각 확인하였으며, 나아가 성격적 특성과 상황적 특성이 상호작용하여 외도 의도를 예측함을 밝혔다. 이를 통해 인간의 행동에 대한 설명과 예측이라는 심리학의 근본적인 목적을 달성하기 위해서는 개인 성격적 특성과 상황적 특성의 영향력을 함께 고려하는 것이 효과적임을 제언하였다.

Abstract

We investigated the interactive effect of person and situation on infidelity intention in romantic relationship. In study 1, married individuals (N = 116) completed an online survey including a measure of narcissism and were asked to respond to infidelity intention questions after imagining themselves as a protagonist in a hypothetical vignette. The protagonist in the vignette has made a big investment into marriage and encounters an attractive opposite-sex person who showed romantic interests in him/her. Results showed that narcissism was positively related to infidelity intentions, and that men had higher infidelity intentions than women. However, the interaction between sex and narcissism was not significant, indicating that narcissism’s effect on infidelity intention was independent of participant sex. In Study 2, we investigated the effects of both person and situation on infidelity intention, as well as the interaction between them. Male students (N = 143) who were not involved in a romantic relationship completed a measure of narcissism and responded to infidelity intention questions after reading a similar vignette to study 1. We manipulated the investment size of the protagonist (high vs. low) and quality of the alternative partner (high vs. low) in the vignettes. Participants showed higher infidelity intentions when the investment size was low or when the quality of the alternative was high. Narcissistic individuals showed high infidelity intentions when both investment size and quality of the alternative were high or both of them were low. These results suggest that it is important to take both person and situation into account when understanding social behavior.
