`titrebSummary`/titrebIn what is a supervision in group radically different from an individual supervision ? What else, what more, what different does the group say ? The author asks himself, from his clinical experience, what the group plan brigs in the analyst’s specific listening and alters in his work. The effects on and in the group caused by the narrator’s account should be regarded as an effect of counter-transference and as a diverted way to it as to what has mobilised it above. In this manner the group works like an echo room and a resonance chamber. Therefore the supervision in group would sound like an « echo-logy ».
