A paired samples t-test was conducted to assess whether
a significant difference
existed between a bilingual’s VIQ at Time 1 (3 month) compared to their VIQ at Time 2
(12 month) and their PIQ at Time 1 compared to their PIQ at Time 2.
On average,
bilingual TBI participants did not have a significant difference between their VIQ (M =
91.11, SE = 3.94) and VIQ2 (M = 94.67, SE = 4.49),
t(8) = -1.042,
p = 0.33. On average,
bilingual TBI participants did not have a significant difference between their PIQ (M =
91.56, SE = 6.06) and PIQ2 (M = 99.56, SE = 2.46),
t(8) = -1.649,
p = 0.14.
