이전 연구에서는 원숭이들이 거울을 이용해서 다른 사물을 관찰할 수는 있었지만 거울에 비친 자기 모습을 알아보지는 못했었다.
연구진들이 원숭이 얼굴에 점을 그리고 거울을 주었으나 원숭이들은 사람처럼 그 점을 만지거나 알아차리지 못했다.
하지만 최근 연구에서 과학자들은 다른 전략을 사용했다. 그들은 원숭이를 거울 앞에 앉히고 얼굴에 레이저 빛을 쏘았다.
2주 정도 지나자 원숭이들은 거울에 비친 자기 모습을 보면서 레이저 빛을 만지기 시작했다.
과학저널 <커런트 바이올로지>는 관련 연구가 치매와 같은 뇌 질병으로 거울 속 자기 모습을 인지하지 못하는 환자들에게 새로운 희망이 될 수 있다고 밝혔다.
