Estimates and standard error (SE) are written in scientific notation.
a
Test session was dummy coded with the baseline test session being the reference category.
b
Congruency was dummy coded with the congruent condition being the reference category.
c
Trial type was dummy coded with the scrambled stimuli being the reference category.
d
Dot-probe position was dummy coded with dots appearing on the left being the reference category.
e
Trial number, time tested, and rank were z-transformed.
