 Before the training, all participants will undergo an extensive pre-treatment assessment as part of the characterization and subtyping of aggression within the large multicenter subtyping studies EU-Aggressotype and EU-MATRICS. The assessment includes clinical and psychometric measures, neuropsychological testing, fMRI 3 active tasks resting state, MRS anterior cingulate cortex ACC and insula and diffusion tensor imaging DTI as well as biosampling bloodsaliva for geneticsepigeneticshormones. Comparison with a typically developing TD control group receiving no intervention will allow to interpret changes in terms of normalization or compensation.
