Subclaims¶

q2 i? Under time pressure, performance scores decreased for all trainees, all reported greater task load, and PFC activity decreased, especially in junior trainees. → Toy 2022 q2 i? Trainees who maintained stable performance under time pressure showed greater bilateral ventral PFC activation, and stress sensitivity was unrelated to experience level and not captured by heart-rate variability or Surgical-TLX self-report. → Toy 2022 (2)

Evidence¶

Toy 2022¶

Toy, S., Huh, D. D., Materi, J., Nanavati, J., & Schwengel, D. A. (2022). Use of neuroimaging to measure neurocognitive engagement in health professions education: a scoping review. Medical Education Online, 27(1). https://doi.org/10.1080/10872981.2021.2016357

q2 · i? · review · r3

The review attributes this fNIRS finding to Modi et al. (2018), examining temporal pressure on laparoscopic suturing performance and neurocognitive correlates of task load; the review reports the descriptive pattern with no effect size printed.

"Performance scores decreased for all trainees under time-pressure conditions when compared to self-pacing. All trainees reported greater task load under time pressure and showed decreased PFC activity, especially junior trainees."

q2 · i? · review · r3

The review attributes this subsequent fNIRS study to the same group [65], comparing trainees who maintained stable performance under time pressure with those who did not; the review adds that stress sensitivity and performance degradation were unrelated to experience level and not captured by heart-rate variability or Surgical-TLX.

"Resilient trainees showed greater bilateral ventral PFC activation, suggesting better attentional control and vigilance."

Discussion¶

Related Claims¶

• Experts show significantly lower prefrontal cortex activation than novices during technical skill performance, but novices may retain persistent PFC engagement even after reaching expert-level observed performance
• 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
