	1	2	3	4
RB-C	0.56 ± 0.16	0.75 ± 0.17	0.75 ± 0.17	0.78 ± 0.19
RB-V	0.46 ± 0.16	0.56 ± 0.21	0.60 ± 0.25	0.58 ± 0.27
II-C	0.54 ± 0.12	0.68 ± 0.16	0.74 ± 0.16	0.74 ± 0.15
II-V	0.43 ± 0.14	0.56 ± 0.19	0.60 ± 0.22	0.63 ± 0.22

RB and II represent the rule-based category structure and the information-integration category structure, respectively. RB-C represents the rule-based category structure control group, RB-V represents the rule-based category structure experimental group, II-C represents the information-integration category structure control group, and II-V represents the information-integration category structure experimental group. The numbers 1, 2, 3, and 4 represent the four blocks of the learning process.
