Subclaims¶

q3 i? In left anterior fusiform, the sensori-motor group showed greater percentage signal change for letters post- versus pre-training (three-way interaction F(2,20) = 10.5, p < .001). → James 2010

James, K. H. (2010). Sensori-motor experience leads to changes in visual processing in the developing brain. Developmental Science, 13(2), 279-288. https://doi.org/10.1111/j.1467-7687.2009.00883.x

q3 · i? · causal · r2

ROI ANOVA in the left anterior fusiform of the same twelve children: significant three-way interaction (F(2,20) = 10.5, p < .001), driven by the sensori-motor group's letter response, "t(10) = 4.48, p < .01"; no other simple effects significant.

"As can be seen in Figure 5, this interaction is driven by the greater percentage signal change in the sensori-motor training group for letters pre-training versus post-training (t(10) = 4.48, p < .01). It should be noted here that no other simple effects in this interaction were significant."
