Table 4. Results of a second post-hoc analysis of the full GLMM, Comparison between groups for each combination of Instruction, Posture, and Congruency.

	anatomical instruction		external instruction
	same orientation	diff. orientation	same orientation	diff. orientation
congruent	z = -0.13, p = n.s.	z = -0.29, p = n.s.	z = 0.73, p = n.s.	z = 2.40, p = n.s.
incongruent	z = 2.67, p = 0.045	z = 2.85, p = 0.031	z = 3.35, p = 0.006	z = -0.09, p = n.s.

Results of the post-hoc analysis of the full GLMM giving a direct comparison of performance of sighted and congenitally blind participant groups. p-values are Holm corrected; see Table D in S1 File, for uncorrected p-values, including non-significant ones. Values with p < 0.05 are set in bold font.
