Subclaims¶

q3 i? The main effect of congruency identified higher BOLD response in left IFG (orbital), bilateral superior frontal gyrus and bilateral ACC for incongruent statements. → Geneviève Allaire-Duquette 2021 q3 i? T-contrasts further showed incongruent statements activated the bilateral cerebellum and left MFG, while congruent statements activated the bilateral middle occipital gyrus more. → Geneviève Allaire-Duquette 2021 (2)

Evidence¶

Geneviève Allaire-Duquette 2021¶

Geneviève Allaire-Duquette, Lorie-Marlène Brault Foisy, Patrice Potvin, Martin Riopel, Marilyne Larose, Steve Masson. (2021). An fMRI study of scientists with a Ph.D. in physics confronted with naive ideas in science. npj Science of Learning 6:11. https://doi.org/10.1038/s41539-021-00091-x

q3 · i? · causal · r2

Whole-brain random-effects full-factorial fMRI analysis of 25 Ph.D. physicists; the main effect of CONGRUENCY at pFWE-corrected < 0.05 showed the three frontal clusters, each with "Higher blood oxygen level ‐dependent (BOLD) response ... for incongruent statements".

"The analysis identi fied a set of areas in the left IFG, bilateral superior frontal gyrus, and bilateral ACC. Higher blood oxygen level ‐dependent (BOLD) response in all three clusters was found for incongruent statements compared to congruent statements."

q3 · i? · causal · r2

Post-hoc t-contrasts (p uncorrected < 0.005) in the same 25-participant whole-brain analysis, reported in the congruency-dependent BOLD modulation section.

"incongruent statements, more than congruent ones, activated also the bilateral cerebellum and the MFG, while conversely the congruent statements activated the bilateral middle occipital gyrus more than incongruent ones."

Discussion¶

Related Claims¶

• When physicists with a Ph.D. judge incongruent statements in biology, where they hold basic expertise, activation overlaps with inhibitory-control regions including left IFG, ACC, insula and superior frontal gyrus — a narrower finding that bears on this claim
• An EXPERTISE × CONGRUENCY interaction in bilateral dorsal ACC shows the congruency effect on BOLD signal is larger for statements in biology, where participants hold basic expertise, than in physics — related
• When physicists with a Ph.D. confront naive ideas in their domain of expertise, MFG and IFG associated with inhibitory control are significantly more activated by incongruent than congruent statements — related
• Naive science ideas are extremely persistent and probably never disappear even after extensive training such as a Ph.D. in physics, so conceptual change as replacement may never truly be achieved — a narrower finding that bears on this claim
• Physicists with a Ph.D. are slightly more accurate judging physics statements than biology statements (d = 0.5) — related
• Problem difficulty, but not accuracy or self-reported strategy, positively modulates dorsal attention and occipital activity during physics problem solving — related
