Computer simulations: contextual interference (CI) effect in the nondisabled model. Performance (black line), fast process (dotted line), and slow process (gray line) are shown during blocked (A) and random schedule training (C). Immediate and long-term retention are shown following blocked (B) and random schedule training (D). Imm, immediate test; Del, 24-h delayed test. Notice the large forgetting following blocked training and slower performance improvement during random than during blocked training. The jitter in the fast process memory (reflected in performance) during random training in C was due to both decay and interferences between the tasks.
