Assistance
The multinomial regression model for tester assistance during task 1 was
not significant (ꭓ2 (2) = 1.27, p = 0.53). The
model for task 2 (ꭓ2 (2) = 8.62, p = 0.01) was
statistically significant and explained 32.3% (Nagelkerke
R2) of the variance in tester assistance across
groups. During task 2, it was 6.67 times more likely for children to
seek partial assistance than no assistance if they were in the DS group
compared to the TD group (Wald’s ꭓ2 = 3.04, p =
0.08). Similarly, it was 20 times more likely to seek total assistance
than no assistance for children in the DS group compared to the TD group
(Wald’s ꭓ2 = 5.61, p < 0.05). The
model for task 3 (ꭓ2 (2) = 9.24, p = 0.01) was
also statistically significant and explained 33.9% (Nagelkerke
R2) of the variance in tester assistance across
groups. During task 3, children were 21.33 times more likely to seek
partial assistance than no assistance if they are in the DS group
compared to TD group (Wald’s ꭓ2 = 5.92, p< 0.05). The percent data for tester assistance during the
three tasks is provided in Figure 3.
