对待同一件事物,或在同一情境下所产生的两种或两种以上不同甚至对立的情绪,同时出现在同一个有机体中,心理学上称之为无确定定向的态度,或者说情绪的无定向性。美国心理学家普拉奇克认为,人的情绪是多维的,它包括强度、相似性和两极性三个维量。意思是说,所有的情绪都能够表现出强度的不同,任何情绪在与其它情绪相类似的程度上都有不同,任何情绪都有相对立的两极。他还认为有机体具有保护←→破坏、生殖←→剥夺、结合←→排斥、探索←→定向四对机能,它们是对立的,能够按强度或彼此间相似的程度而发生变化。普拉奇克的情绪三维模式的理论,其立足点是建立在生物学基础之上的,由于从生物学意义上说,情绪具有很广的含义,因而这个模式的用处是有限的,但它为我们提供了这样一个事实;由于原始情绪是短暂的,一般由外界刺激物所激发,而有机体互相对立的四对机能又是互相制约,互相排斥,倾轧争 Treat the same thing, or two or more different or even opposite emotions produced in the same situation, appear in the same organism at the same time, psychologically call it an attitude of no definite orientation, or emotionally without Directivity. Prachik, an American psychologist, believes that human emotions are multidimensional and include three dimensions: intensity, similarity and polarity. This means that all emotions can show different intensities. Any emotion has a similar degree to other emotions, and any emotion has opposite poles. He also believes that the organism has four functions of protection ← → destruction, reproduction ← → deprivation, combination ← → exclusion, exploration ← → orientation, and they are opposite and can change in intensity or similarity to each other. Prachik’s Theory of Emotional Three-Dimensional Model, whose standpoint is based on biology, is of limited usefulness due to the wide range of emotions in the biological sense, but it is of limited use Provides us with the fact that since the primitive emotions are short-lived, they are generally inspired by external stimuli, and the four pairs of functions in which organisms oppose each other are mutually restraining, mutually exclusive,
