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. ...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: ①Practice effect is one of the factors affecting subject’s practice result change; ②In order to eliminate the confusion of the self-independent variables 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.展开更多
