Limitations and strengths of the current study
fatigue
One limitation of our study was the short training period. One could argue that the children of both groups were beginners and that a longer learning period might have disclosed a larger difference between the groups. On the other hand, a longer series of Chinese lessons than in the present study could provide more time for repetition so that more characters could be stored in long-term memory. Another limitation is the limited number of stimuli, which we accepted in order to prevent fatigue in the children by further extending the time spent in examination.
