Subclaims¶

q3 i? No significant BOLD modulations were observed in a priori ROIs for accuracy, difficulty, or strategy, but exploratory whole-brain analysis showed DAN and occipital activity positively modulated by problem difficulty. → Bartley 2019

q3 · i? · associational · r2

Separate within-subject parametric modulation GLMs for accuracy, normative difficulty (miss rate), and self-reported strategy in 107 students. The null ROI findings and the exploratory whole-brain difficulty effect are reported together; the article states the reasoning network is activated regardless of whether a correct answer is achieved.

"While no signi ficant BOLD signal modula- tions were observed in these a priori ROIs, an exploratory whole- brain parametric modulation analysis revealed that DAN and occipital activity were positively modulated by problem dif ficulty"

• Judging incongruent statements that trigger naive ideas recruits left IFG, bilateral superior frontal gyrus and bilateral ACC more than judging matched congruent statements — related
• Task nature modulates brain activation: problem-solving tasks and difficult cases induced higher activation than simple recall or routine cases, and incorrect answers induced higher PFC activation than correct answers — related
