Table 2.

Pearson’s chi-square test (2-sided) was used to assess whether the performance depends on the direction of the rotation

Participant	1	2	3	4	5	6	7	8	9	10
p value	.317	.679	.591	.724	.686	.170	.961	.559	.379	.186

For each participant, the trials of the stimuli levels next to the individual thresholds of each participant were combined over all conditions yielding on average 155 trials per direction. No significant performance differences between leftward and rightward rotations were found
