q2 i? A one-standard-deviation increase in the nondominant eye's average pupil diameter (subject-wise standardized) was associated with an 8.13-point decrease in Tubes performance score (p = 0.01), and a one-standard-deviation increase in rate of saccade was associated with a 5.87-point decrease (p = 0.04). → Shafiei 2024

q2 · i? · associational · r2

Linear random intercept regression on 61 Tubes attempts from 26 subjects (Tobii eye-tracking at 50 Hz), with subject as random effect (p = 0.02), pseudo R2 = 0.71. The model reports "an 8.13-point decrease in their performance score" per SD increase in pupil diameter; rate of saccade entered with estimate −5.87 (p = 0.04). No standardized effect size printed.

"A one standard deviation increase in the average pupil diameter of the subject's nondominant eye (standardized for each subject) was associated with an 8.13-point decrease in their performance score."
