The embryology of behavior--This title of a book by the great developmental psychologist Arnold Gesell (Gesell, 1945) continues nicely to encapsulate for me a core endeavour in child psychology and psychiatry; in the use of scientific method to tease out causes and processes within developmental science and psychopathology. This edition of JCPP includes some tremendous examples of the increasing rigour and sophistication with which such questions are being addressed. Particularly encouraging for me, as primarily an interventionist, is the use of well-designed randomized controlled trials (RCTs) for that end.
行为发生论——伟大的发展心理学家阿诺德·格塞尔（Gesell，1945）撰写的一本著作的书名很好地概括了我在儿童心理学和精神病学领域的核心工作：即利用科学方法来梳理发展科学和精神病理学中的因果关系和过程。本期《儿童心理学与精神病学杂志》（JCPP）包含了一些非常好的例子，说明了这些问题的解决方法在日益严谨和复杂。作为一个干预主义者，我特别感到鼓舞的是，为了达到这个目的，人们正在使用精心设计的随机对照试验（RCT）。
