1. 엔터테인먼트 과학적으로 유익한 비디오 게임 디자인 <ol><li> 과학 가치와 playability의 우려가 서로를 통보하는 게임 디자인 과정을 반복 적용합니다. 실험자로서, 당신이 컴퓨터 게임에 내장된보고 싶어하는 자극과 행동 패러다임에 대해서 생각을했습니다. 당신은 게임 디자이너가 아니기 때문에, 게임에 이러한 패러다임을 구축하는 작업은 대부분의 작업이 완료되면 해결될 수?...

아마 통합 연구에 가장 중요한 장애물은 하나의 실험 주제가 (임상 인구에서 특히 하나) 합리적으로 피로되기 전에 수행할 수 있을런지 그 당시의 금액에 대한 실질적인 한계입니다. 불행히도, 종종 더 많은 제어 자극 볼의 과학자의 관점에서이고, 더 반복하고 지루한 실험을보기의 주제의 관점에서 보일 수있다. 최근 neuropsychiatric 장애에 대한 Behavioural 연구 동기 부여의 중요성,인지 전략을 수립?...
