Table 1 Gaze metrics indexing processes that may support improvements in reasoning
From: Eye gaze patterns reveal how reasoning skills improve with experience

Visual search | Decrease in the number of fixations on any scale before homing in on the relevant scales | 5.75 [4, 7] | 5 [4, 5] | 6.51* (±<0.00) | 5 [4, 5.75] | 4 [3, 5] | 0.67 (±<0.00) | 0.60 (±2.79) |
Relational thinking | Decrease in the total duration of fixations on relevant relations after homing in on the relevant scales | 2526.5 [1010.50, 3259.00] | 1122.5 [555.99, 1854.50] | 240.03*** (±<0.00) | 1635.75 [1069, 2256.25] | 1725 [1387.5, 1990.18] | 0.30˙ (±0.02) | 3.66* (±1.98) |
Relational integration | Fewer saccades between the two relevant scales after homing in on the relevant scales | 3 [1.75, 3.75] | 2 [1, 3] | 3.15* (±<0.00) | 2 [2, 3] | 2.5 [2, 3] | 0.14˙ (±<0.00) | 1.58 (±2.62) |
