摘要：

Objective:To confirm the least practice times to eliminate the practice effect in the Working Memory Test. Methods: Four university students aged 19 to 24 were selected and tested at 8: 30~ 11: 30 A. M., 2: 30~ 5: 30 P. M. and 7: 30~ 9: 30 P. M. respectively in two days, and their behavioral data were collected. Results: From the data of the four analyzed subjects, there are significant practice effects in the Working Memory Test (two types, three difficult levels), comparing with their practice results fore- and- aft, the difference of practice results reaches the significant level (P < 0.05). Conclusion: 1 Practice effect is one of the factors affecting subject. s practice result change; o In order to eliminate the confusion of the self- independent var-i ables resulting from practice effect in the formal test, the practice times suggested is no less than 18 in all 6 subtests before the formal tests.
