Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? In young children, occipital cortices respond to sound in blind but not sighted children. → Bedny 2015
Evidence¶
Bedny 2015¶
Bedny, M., H. Richardson, and R. Saxe. (2015). "Visual" Cortex Responds to Spoken Language in Blind Children. Journal of Neuroscience. https://doi.org/10.1523/jneurosci.0634-15.2015
q3 · i? · associational · r?
A neuroimaging study comparing blind and sighted children listening to auditory stimuli found that "visual" cortices of young blind (but not sighted) children respond to sound. No effect size is printed for this group contrast.
"We find that “visual” cortices of young blind (but not sighted) children respond to sound."
Discussion¶
Related Claims¶
- Occipital plasticity for spoken language is independent of plasticity for Braille and for sound
- Occipital responses to spoken language in blind children are maximal by age 4 and unrelated to Braille learning
- Occipital responses to nonlanguage sounds in blind children increase between ages 4 and 17
