Abstract

The present study investigated whether 6- and 12-month-old infants could infer an agent's social preference on the basis of intentions. In Experiment 1, 12-month-old infants were first familiarized with two kinds of event: the helping and the hindering events. In the helping event, an agent (either a square or triangle) tried to help a circle climb up the hill and the movie stopped right before the circle reached the top of the hill. Thus, the outcome of the helping behavior was made to be ambiguous. Similarly, in the hindering movie, another agent tried to hinder the circle from reaching the top of the hill and the movie stopped right before the circle slipped down to the base of the hill making the final outcome of the hindering behavior unclear. During the test trial, infants were either presented with an event in which the circle approached the helper (approach-helper condition) or an event in which the circle approached the hinderer (approach-hinderer condition). The results indicated that both 6- and 12-month-olds looked longer at the approach-helper event than at the approach-hinderer event. Thus, by 6 months of age, infants are sensitive to agents' intentions when reasoning about agents' social preference. The current findings add to the emerging evidence on social evaluation and moral reasoning during infancy.

본 연구는 6개월 및 12개월 영아들이 행위자(agent)의 사회적인 선호를 추론할 때, 이전에 있었던 사회적 상호작용 내의 행동 의도 정보를 고려할 수 있는지 살펴보았다. 친숙화 시행에서 12개월(실험 1), 6개월(실험 2) 영아들은 한 도형(세모 또는 네모)이 동그라미를 밀어 올려서 동그라미가 언덕을 오를 수 있도록 돕는 장면과 다른 도형이 동그라미를 아래쪽으로 밀어서 언덕을 오를 수 없도록 방해하는 장면을 보았다. 이 때, 도움 행동과 방해 행동의 의도만 제시하고, 행동의 결과, 즉 목표 달성의 성공 또는 실패는 명확하게 보여주지 않았다. 검사 시행에서 영아들은 동그라미가 도움자 도형에게 접근하는 장면(도움자 접근 조건)을 보거나 방해자 도형에게 접근하는 장면(방해자 접근 조건)을 보았다. 그 결과, 두 연령 집단 모두 방해자 접근 조건일 때보다 도움자 접근 조건일 때, 검사 시행을 유의미하게 더 오래 보았다. 이는 6-12개월 영아가 행위자의 의도를 고려해서 도움자와 방해자를 구별할 수 있으며 이러한 정보를 바탕으로 행위자의 사회적 선호를 추론할 수 있음을 보여준다. 본 연구 결과는 영아들이 돕기와 같은 도덕 관련 행동의 의도를 고려할 수 있고, 이를 통해 행위자의 사회적 선호를 추론할 수 있는 능력이 생후 1년 이내에 존재할 수 있음을 보여준다.
