Success
The logistic regression analysis for success of task 1
(ꭓ2 (1) = 0.88, p = 0.35) and task 3
(ꭓ2 (1) = 0.2, p = 0.66) indicated no effect of
group. In contrast, the regression model for task 2 produced a
statistically significant difference (ꭓ2 (1) = 4.43,p < 0.05) and explained 21.6% (Nagelkerke
R2) of the variance in success. Children in the DS
group were 0.16 times less likely to succeed in task 2 compared to
children in the TD group (Wald’s ꭓ2 = 3.84, p =
0.05). The percent success data for both the groups during each of the
experimental tasks is provided in Figure 2.
