唐纳德·威尼科特1896—1971

他在40年的时间里研究人类成长，希望阐明个体通过依靠如何发展为既定的存在方式，个体如何发展出自认为正常、并又与人有别的感觉。他认为不间断的照料是早期成长中必须的，而本能生活只是基本需要的一个“并发症”。连续性的间断会导致精神病，而父母往往需要对此负责。超出儿童理解力的事情会造成精神创伤。他着重研究了创伤经历，并认为个人发展常常需要与适应环境的倾向作斗争。

温尼科特最出名的是他对“真实自我”（英语：true self）和“虚假自我”（英语：false self）的概念。

Donald Woods Winnicott (7 April 1896 – 25 January 1971) was an English paediatrician and psychoanalyst who was especially influential in the field of object relations theory and developmental psychology. He was a leading member of the British Independent Group of the British Psychoanalytical Society, President of the British Psychoanalytical Society twice (1956–1959 and 1965–1968), and a close associate of British writer and psychoanalyst Marion Milner.

Winnicott is best known for his ideas on the true self and false self, the "good enough" parent, and he and his second wife, Clare, arguably his chief professional collaborator, worked with the notion of the transitional object. He wrote several books, including Playing and Reality, and more than 200 papers.
