q2 i? Each one-unit increase in first-attempt performance score was associated with a 0.35-point decrease in learning rate (p = 5 × 10−4), and greater temporal flexibility in BA 46 at alpha-band frequencies was associated with a 0.87-point decrease in learning rate (p = 7 × 10−4) in the Tubes task. → Shafiei 2024 q2 i? In Dots and Needles, greater search information in BA 45 (estimate 1.92, p = 0.0006) and BA 40 (estimate 1.45, p = 0.0009) at first attempt was associated with higher learning rates, as was temporal flexibility in BA 41 at theta band (estimate 0.41, p = 0.021). → Shafiei 2024 (2)

Shafiei, S. B., Shadpour, S., Sasangohar, F., Mohler, J. L., Attwood, K. & Jing, Z. (2024).

q2 · i? · associational · r1

Multivariate linear regression for Tubes learning rate, defined as the slope of performance scores across attempts, using first-attempt features (26 subjects; R2 = 0.64, MAE 4.89, RMSE 5.73). First-attempt score was included as a baseline to adjust for individual differences.

"Furthermore, each one-unit increase in initial performance score was associated with a 0.35-point decrease in learning rate, implying that subjects with higher initial scores tend to exhibit lower learning rates."

q2 · i? · associational · r1

Multivariate linear regression for Dots and Needles learning rate (26 subjects; R2 = 0.69, MAE 5.69, RMSE 7.15) with first-attempt EEG features. In Suture Sponge, search information in BA 19 at gamma band was associated with a 1.19-point increase in learning rate (p = 0.01), while BA 45 theta features were associated with decreases.

"A one-standard deviation increase in the average search information in BA 45 at beta-band frequencies was associated with a 1.92-point increase in the learning rate value for this task."
