  1. Time: ”pre”= ERP measures before treatment (SCP Neurofeedack Training and TAU), “post”= ERP measures after treatment. Group: CG = Control Group; EG = Experimental Group. SD = Standard Deviation. mV = microvolt. n refers to sample size after excluding outliers. For the ERP analysis, three participants (one control, two experimental) were excluded due to low EEG data quality.
