Phase 3 performance. (A) Training trial (light gray) and test trial (dark gray) performance shown for subject Groups I and II (i.e., performance averaged across all blocks in phase). (B) Test trial performance as a function of symbolic distance, Group I (light gray), Group II (dark gray). (C) Performance of each subject group on hierarchy recall test. See Materials and Methods for scoring scheme. Note chance performance has mean 26 errors (SD 6), based on simulation (involving 1000 randomly generated hierarchies). Error bars reflect SEM.
