The author describes the methodology and the strategies developed in the margins of a research project which aims at the psychoanalysis of the translational performance starting from a corpus of oral translations (German-English and vice versa) in the aim of reconstructing the strategies which underlie translation. Then the author presents the elements of translation strategies. Finally, the author gives some examples for the application of his model of analysis. He ends by a quantitative analysis of translation strategies from and into the mother tongue.
