In The Expression of Emotions in Man and Animals Darwin argued that emotions are not unique to humans, but can be found in many species; that many of the same social occasions that generate emotions in humans do so in other animals. He asked why this particular expression for a particular emotion, and his answer formed part of his demonstration of the continuity of the species and was thus crucial to his evolutionary theory. Darwin was one of the first scientists to use photographs as illustrations and to use the judgment method for studying the signal value of an expression-which has become the most frequently used method in the psychology of expression. The contents of the present volume extend, support, and sometimes contradict Darwin's remarkable contribution to the field of the expression of emotions.
在《人类和动物的表情》一书中，达尔文认为情感并非人类所独有，而是在许多物种中都能找到；许多在人类中引发情感的社交场合，在其他动物中也会引发同样的情感。他问道，为什么会有针对特定情感的特定表达方式，他的答案构成了他对物种连续性论证的一部分，因此对他的进化论至关重要。达尔文是最早将照片用作插图，并使用判断方法来研究表情的信号价值的科学家之一——这一方法已成为表情心理学中最常用的方法。本书的内容扩展、支持了达尔文在情感表达领域的卓越贡献，有时也与之相矛盾。
