Subclaims¶

q3 i? Only after sensori-motor training did letters activate the left posterior fusiform more than similar stimuli, with a significant three-way interaction of Training Group, Imaging Day and Stimulus. → James 2010

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 analysis in twelve pre-literate children randomly assigned to sensori-motor (printing) or visual-only training, scanned pre- and post-training. In left posterior fusiform, the three-way interaction was significant (p < .001), with letters pre- versus post-training t(10) = 5.77, "p < .001".

"This three-way interaction supports the hypothesis that only after sensori-motor training do letters activate the left fusiform more than other, similar stimuli (see Figure 4) (t(10) = 5.77, p < .001 for letters pre-training versus post-training)."

Discussion¶

Learner Variables¶

• Visual Processing — outcome: instruction changes it
