Sometimes abbreviated as IRM. It is considered the most fundamental mechanism that causes animal behavior, and is the mechanism that explains the expression of genetically programmed behavior. The term releasing mechanism (Auslösemechanismus in German) was proposed by K. Lorenz. It is based on the idea that behind an animal's innate behavior, there is always stored potential energy to express it, and that the behavior is expressed by a releaser (or a key stimulus contained in it) that draws out this potential energy.

IRMと略記することもある。動物の行動を引き起こす最も基本的なしくみと考えられるもので,遺伝的にプログラムされた行動の発現を説明する機構。解発機構(ドイツ語でAuslösemechanismus)の語はK.ローレンツの提唱になる。動物の生得的な行動の背後にはそれを発現する潜在的エネルギーがつねに蓄えられた状態にあり,これを引き出すリリーサー(あるいは,それに含まれる鍵刺激)によってその行動が発現するという考えに基づくもの。
