headline: Screening efficiency over experience: Rapid target detection in low-power field as a modifiable cognitive biomarker for diagnostic accuracy in digital cytology
dek: Background Traditionally, cytology expertise has been equated with professional experience. However, the transition to whole-slide imaging and artificial intelligence (AI) necessitates a shift from exhaustive screening to rapid verification. The goal of this study was to identify cognitive biomarkers associated with diagnostic accuracy and evaluate their modifiability. Methods In phase 1, 100 cytotechnologists with 1-40 years of experience diagnosed 30 digital cytology images using eye-tracking. Gaze metrics acr…
gain_title: Efficient low-power field target detection, measured as shorter fixation duration and faster time to first target fixation, predicts higher diagnostic accuracy in digital cytology and can be rapidly acquired through standard 3-month training.
problem_title: Inefficient low-power field target detection, reflected in longer fixation duration on the LPF main object, predicts lower diagnostic accuracy, while traditional years of professional experience fails to predict accuracy in digital cytology.
trace_subject: low-power field target detection efficiency and diagnostic accuracy in digital cytology
gain_reading: Efficient low-power field target detection, measured as shorter fixation duration and faster time to first target fixation, predicts higher diagnostic accuracy in digital cytology and can be rapidly acquired through standard 3-month training.
gain_evidence: shorter total fixation duration on the "low-power field (LPF) main object" as the sole independent predictor of high accuracy (p = .045) | time to first target fixation decreased substantially (r = 0.62-0.86) | Efficiency in LPF target detection is a better predictor of diagnostic accuracy than professional experience
problem_reading: Inefficient low-power field target detection, reflected in longer fixation duration on the LPF main object, predicts lower diagnostic accuracy, while traditional years of professional experience fails to predict accuracy in digital cytology.
problem_evidence: Years of experience showed no significant correlation with diagnostic accuracy (r = 0.189, p > .05) | shorter total fixation duration on the "low-power field (LPF) main object" as the sole independent predictor of high accuracy
quick_read: Researchers eye-tracked 100 cytotechnologists diagnosing 30 digital cytology images and then tracked 28 students before and after a 3-month training program. They found years of experience did not predict accuracy, while shorter fixation on the low-power field main object did, and students markedly improved time to first target fixation and reduced background attention after training.

The findings matter because digital cytology and AI are moving the role from exhaustive screening to rapid verification, requiring new objective measures of competence beyond seniority. Uncertainty remains about how these gaze biomarkers generalize to real-world whole-slide workloads, diverse case mixes, and actual AI-assisted practice, which the study did not directly test.

tag: Automated dual reading
key_points: 100 cytotechnologists with 1-40 years experience diagnosed 30 digital cytology images with eye-tracking; years of experience did not correlate with accuracy. | Multivariate analysis found shorter total fixation duration on the LPF main object was the sole independent predictor of high accuracy, suggesting pop-out detection. | 28 students after 3-month training showed large reductions in time to first target fixation and reduced attention to normal backgrounds, indicating acquisition of expert-like selective attention.
rundown: Phase 1 used nominal logistic regression on gaze metrics across areas of interest for 100 cytotechnologists; experience correlated only with attention to sample information, not accuracy. Phase 2 used Wilcoxon signed-rank tests to compare pre- and post-training metrics in 28 students.

Authors propose quantifying LPF efficiency as an objective, modifiable cognitive biomarker for evaluating skill development and readiness for AI-assisted verification workflows, shifting emphasis from exhaustive screening to rapid verification.
