Comparison of within session reliability across methods and template sets using ICC2,1 (Shrout and Fleiss, 1979). Due to the presence of group differences ICCs were computed separately for young and old subject groups. The pattern of results reveals approximate equivalence across methods with a slight advantage for out-of-sample templates (OST) relative to in-sample templates (IST). IST-DAN and IST-Language were excluded due to poor fits with the OST templates; NAs for prior report seeds reflect unspecified networks.
