Results for the scaling distances calculated from the size settings

Predictor	Estimate	SE	t	DF	p	Lower	Upper
Intercept	17.756	4.8614	3.6524	3996	0.00026318	8.2245	27.287
Headset	7.8532	6.8807	1.1413	3996	0.2538	− 5.6368	21.343
Distance	0.37739	0.067201	5.6158	3996	2.0898e-08	0.24564	0.50914
Headset-by-distance	0.13453	0.095099	1.4146	3996	0.15726	− 0.051918	0.32098

Effective distance increased with rendered distance at a rate of 38 %, indicating incomplete scaling. There was no effect of headset, and no headset-by-distance interaction. These results indicate no difference in size constancy in the two headsets
