Paper about 3 salience components that guide your habitual eye movement.
Motivational salience component is always in the background to control your eye movements.
It’s beneficial in relearning of forgotten values.
 
지금까지 Motivational salience가 존재한다는 것을 알고 있었으나, 실험 상으로 정확하게 관찰하기 어려웠습니다. 본 연구에서는 인간참여자가 시각물체-금전보상에 대해서 기억하게 한 후(장기기억), 30일 뒤에 어떤 물체를 보는지 관찰했습니다.
30일 뒤 참여자들이 물체의 가치를 어느 정도 잊게 되었고, 이 상황에서 단순히 좋은 물체를 기억하지 못해서 잘 보지 못하는 현상이 일어나는 것이 아니라, 재미있게도 좋은물체와 나쁜물체 모두를 보는 현상을 관찰했습니다.
따라서, 인간이 무의식적으로 물체에 주의집중을 할 때는 물체자체의 성질(perceptual salience), 학습된 가치(reward salience), 마지막으로 motivational salience가 모두 작동하여 물체를 자동적으로 응시하게 된다는 사실을 알게 되었습니다. 이는 본 논문에서 행동실험을 기반으로 한 컴퓨터 인지행동 모델링으로 증명되었습니다. 
또한, 이 현상이 30일이 지난 망각상황에 국한된 것이 아니라, 일반적으로 많은 인지실험논문에서 다루는 학습이 일어난 직후에도 이 3가지 주의집중 요소들이 항상 작동하고 있다는 것도 이론이 아닌 인지행동실험을 기반컴퓨터 모델링으로 보였습니다.
더 나아가, 이렇게 망각이 일어나는 경우에 motivational salience기반으로 기억을 되짚어 보는 선택이 가치 재학습에 가장 좋은 전략(strategy)이라는 사실을 컴퓨터 모델링으로 증명했습니다.

이 연구를 통해 세계에서 유래없는 인간-영장류동물연구를 동시에 할 수 있는 기반을 한국에 세웠습니다. 이를 통해 무의식적으로 가치가 높은 물체를 찾는 행동을 위한 자동적 기억인출이 영장류의 복부선조체에서 일어난다는 사실을 처음으로 밝혔습니다. 이 결과는 하나의 동물모델과 하나의 연구기법을 사용한 것이 아니라, 인간에서는 fMRI를 사용하고 영장류 동물모델에서는 전기생리학을 이용하여 물체가치기억의 자동인출이 복부선조체에서 일어난다는 사실을 명확하게 밝혔습니다. 이를 통해 복부선조체의 기존 RPE이론을 넘어서서 새로운 학습과 기억 이론을 말할 수 있는 기반을 마련했고, 나아가 중독과 조현병과 같은 정신질환을 이해하는데 중요합니다.
