Table 3.

Motion measures, mean, and standard deviation (SD) for children at T1, T2, and T3.

	Mean (SD) (total: generating verbs and tapping fingers)	Mean (SD) (generating verbs)	Mean (SD) (tapping fingers)	t Test (generating verbs vs. tapping fingers) (ns)
T1 children	0.3 (0.22)	0.33 (0.22)	0.3 (0.21)	0.38
T2 children	0.39 (0.36)	0.43 (0.53)	0.37 (0.22)	0.26
T3 children	0.33 (0.3)	0.32 (0.31)	0.34 (0.3)	0.43

Means and standard deviations (SDs) for motion measures for the total task (generating verbs and finger tapping), the task condition (generating verbs), and for the contrast condition (finger tapping) across the different age groups. No significant differences were found between the different age groups for the total motion parameter as well as between the task and contrast conditions (left column).
