Subclaims¶

q3 i? On false-belief items analyzed separately, blind and sighted children did not differ in performance (group effect controlling for age: b=−0.10, t=−1.5, p=.15). → Richardson H. 2023

Evidence¶

Richardson H. 2023¶

Richardson H., Saxe R., Bedny M. (2023). Neural correlates of theory of mind reasoning in congenitally blind children. Developmental Cognitive Neuroscience. https://doi.org/10.1016/j.dcn.2023.101285

q3 · i? · associational · r2

Analysis of false-belief items from the non-visual ToM task in 12 blind and 21 sighted children. The article reports "blind and sighted children did not differ in performance"; equivalence was not tested and no effect size was printed.

"When looking at the false-belief items separately, blind and sighted children did not differ in performance (group effect, controlling for age: b=−0.10, t=−1.5, CI=[−0.23,0.04], p=.15; Supplementary Figure 3)."

Discussion¶

Related Claims¶

• Explicit mentalizing (false-belief understanding) emerges robustly between ages 4 and 6 — related
• RTPJ selectivity correlates with behavioral ToM task performance across blind and sighted children combined
• Inter-region correlations within the ToM network are lower in blind children, while ToM and language networks remain functionally distinct — related
• Blind children reason about visually sourced mental states similarly to sighted children — related
• Congenitally blind children perform slightly less accurately on a non-visual behavioral ToM task than sighted children, controlling for age — a broader claim this one bears on
