Chunk #38 — Results — Further Examination of the Relationship between TF-PCA and Time-Domain Measures — Mean ERP amplitude within the time range defined by TF-PC3
In total, these follow-up analyses further demonstrated that the TF-PCA method represents the averaged event-related activity in a more comprehensive and detailed manner than do typical time-domain and TF analysis methods. Beyond delineating more refined time windows in which to focus analytic efforts, TF-PCA was able to parse the ERP signal into its constituent components – components with a unique relationship to externalizing spectrum disorders. In the present paper, the P3-related delta activity represented by PC3 remained a significant determinant of group membership when compared to a variety of measures, supporting its role as a potential endophenotype for externalizing.
