Subclaims¶

q3 i? Between-group whole-brain ANOVA and post hoc tests showed Groups A and B (more coherent) had greater lOFC and V5/MT+ activity than Group C, while Group C showed greater cuneus, ACC, insular, and sensorimotor activity. → Bartley 2019

q3 · i? · associational · r2

Whole-brain one-way ANOVA on FCI > Control activity across the three normative groups, with post hoc pairwise tests (P < 0.001 CDT, P < 0.05 CET FWE corrected). No significant differences were observed between Groups A and B. The authors suggest less coherent reasoners engage more visual search for salient problem features.

"Overall, the student who answered by using more coherent physics conceptions, even if incorrect, showed increased reliance on a lOFC-V5/MT + network, whereas students who held less consistent ideas involving multiple conceptual approaches showed increased primary visual and SN activity."

• Physics problem solving engages a fronto-temporo-parietal network including PFC, PPC, RSC, and V5/MT+ relative to control questions — related
• Observational learning is associated with changed functional connectivity between V5/MT and sensorimotor areas, and pre-learning sensorimotor connectivity predicts subsequent learning gains — related
• Sequential problem-solving phases recruit dissociable networks: fronto-temporo-parietal at initiation, dorsal attention at question presentation, and default mode at answer selection — related
• A network of three mutually overlapping intuitive ideas (less distance implies less time, bunched up means faster, faster implies less time) stabilizes students' initial thinking — related
• Module analysis of FCI responses identified 13 student subgroups, with three normative groups differing in accuracy (77%, 73%, 53%) and in conceptual coherence — related
