Trajectory models for P300 amplitude by age range for females. The same number of trajectory classes were identified in females as in males. For ages 8–12 years of age three classes provide the best fit to the data, while four classes characterize those between the ages of 13–18 and 19–29. It may be noted that in comparison to males, fewer females follow the low P300 trajectory (class 3 pattern) particularly during the ages of 8–12 years.
