VA: visual first-then-auditory condition; AV: auditory first-then-visual condition.

“−” represents VA conditions, while “+” represents AV conditions. N_D represents the linear distance between numbers. P_digit represents the physical similarity between Arabic digits. P_auditory represents the physical similarity between auditory number words.

^*p ⩽ .0166 (Bonferroni corrected for three predictors); **p ⩽ .001.
