The reissue of this classic textbook, directed by Olivier Douville, was necessary. The construction of the unit is clear and ingenious. First epistemology or a thought about the objects and methods, the scientific. Then an overview of the main methods (interview, group analysis, observation, projective methods) the best specialists are there who can speak directly to students, young researchers and professionals (Jacobi, Villerbu, Sirota,). The passages on the Rorschach are also remarkable acuity. Finally the question of ethics is considered and the debate with the code of ethics is restarted. Olivier Douville, the contractor is present in each of these three sections. Index and useful bibliography.
