Note. Abbreviation: RMS = root mean squared.
T and p values refer to incongruent versus congruent contrasts.
Indicates significant difference between incongruent and congruent conditions.
Lateral position deviation was significantly different from zero for the incongruent condition; T and p values refer to one‐sample T tests. The descriptive statistics for lateral position deviation for the congruent condition are presented for reference.
