Table 4.

Number of participants using different strategies by age group.

Age group	1-Dim (%)	Multi (%)	Other (%)	Total
4.0–6.0	4 (20)	2 (10)	14 (70)	20
6.0–8.5	18 (42)	8 (18)	17 (40)	43
8.5–11.0	24 (53)	6 (13)	15 (33)	45
11.0–13.4	20 (43)	11 (24)	15 (33)	46
Adults	13 (54)	5 (23)	5 (23)	23
total	79 (45)	32 (18)	66 (37)	177

1-Dim is the number of participants performing single-dimensional classification of the generalization stimuli; multi is the group that performs based on a multi-dimensional strategy, and other are the remaining two classes.
