rG, rE: The correlation between genetic and nonshared environmental factors. These are combined with the standardized estimates of the traits (Table 4) to establish the genetic (rph-a) and unique environmental (rph-e) contributions to the total phenotypic correlation (rPh).
EEG, electroencephalographic; AmM, mean amplitude; AmV, variability in amplitude; PhM, mean phase; PhV, phase variability; RTV, reaction time variability.
