A system for conditioning an organism by associating a conditioned response with a conditioned stimulus, the system comprising the following. Identifying means for identifying a signal pattern associated with a conditioned response (201). Measuring means for measuring a signal of the organism for obtaining a measured signal (202). A comparer for comparing the measured signal with the signal pattern (203). A stimulus renderer for rendering a conditioned stimulus (204) when the measured signal matches the signal pattern, for conditioning the organism such that it associates the conditioned stimulus with the conditioned response, and for further rendering the conditioned stimulus for evoking the conditioned response, at a time which depends on the measured signal.条件反応を条件刺激に関連付けることにより生物を条件付けるシステムであって、条件反応に関連付けられた信号パターンを識別する識別手段(201);測定信号を得るために前記生物の信号を測定する測定手段(202);前記測定信号を前記信号パターンと比較する比較器(203);前記測定信号が前記信号パターンに合致したとき条件刺激を提供し、前記生物が前記条件刺激を前記条件反応に関連付けるように前記生物を条件付け、前記測定信号に従った時間に前記条件応答を想起させる条件刺激を更に提供する刺激提供器(204);を有するシステム。
