Correlations of image parameters with naturalness rating and RTs^a

Image parameter	Naturalness rating			RT
	ρ	p	% of subjects (FDR-corrected)	ρ	p	% of subjects (FDR-corrected)
CE	−0.08	0.0007	71%	−0.2	2.9e-16	86%
SC	0.39	2.3e-58	100%	−0.01	NS	43%
Fs	−0.19	1.3e-15	100%	−0.18	2.4e-13	78%
Fi	−0.36	2.5e-50	100%	−0.09	6.7e-5	71%

^aReported are Spearman correlation values (ρ), corresponding significance values (p), and the percentage of subjects whose individual rating or RT was significantly correlated with the image parameters. NS, Not significant.
