Correlation matrices (Pearson r) for similarity scores

Higher-order concept	Matrix of comparison of super-subjects
Household items*		B1	B2	S1
	B2	0.92
	S1	0.93	0.94
	S2	0.94	0.95	0.96
Fruits and vegetables†		B1	B2	S1
	B2	0.89
	S1	0.89	0.88
	S2	0.90	0.89	0.93

z score of difference between S and B weights on clusters based on distribution from permutation analysis. B, blind; S, sighted; B1, blind super-subject 1; B2, blind super-subject 2; S1, sighted super-subject 1; S2, sighted super-subject 2.

*B − S = 0.97.

^†B − S = 0.93.
