§ Individuals showing a significant improvement in performance in single-case analyses (Huber, 1973). * Because of the lack of normed values for these tasks, the single-case analysis could not be performed.

In these analyses the difference in performance (pre- vs. post-test) obtained by each individual is compared to critical values obtained from published norms. (+) Performance was higher in post- compared to pre-test; (−) Performance was lower in post- compared to pre-test; (=) Performance was in pre- and post-test the same.
