Ritualization

Japanese: 儀式化 - ぎしきか（英語表記）ritualization

This refers to the process in which a certain behavioral pattern, which may be useful for communication between animals, becomes functionally strengthened during the course of evolution and becomes specialized to increase clarity and precision. Often, practical actions are transformed into symbolic actions, and appear in the form of simplification, repetition of essential parts, and emphasis on certain elements. This concept was proposed by J. Huxley (1914) based on his observations of the courtship behavior of great crested grebes. In general, ritualistic behavior is often seen during mating or fighting, and the body shape, color, and patterns associated with this behavior often become specialized.

Japanese:

動物どうしのコミュニケーションに役だっているようなある行動パターンが，進化の過程で機能的に強められ，明確さや精密さを増すように特殊化していくことをいう。しばしば実質的行為が象徴的な行為に変化し，単純化，本質的部分の繰返し，一部の要素の強調といった形で現れる。この概念はJ.ハクスリーがカンムリカイツブリの求愛行動の観察をもとに提出したもの(1914)。一般に儀式的な行動は配偶時や闘争時に多くみられ，またその行動と結びついた身体の形や色，模様などが特殊化することが多い。
