Table 2. Correlation of awareness and adaptation.

		Awareness index
		20°	40°	60°
Adaptation index	first bin	0.76***	0.73***	0.51*
	last bin	0.32	0.60**	0.30
Clamp trial index	first bin	0.51*	0.70***	0.59**

Pearson product-moment correlation coefficients of the correlations between awareness and adaptation (first and last bin) or clamp trial indices (first bin) are shown, respectively. Symbols ***, **, and * indicate p<0.001, p<0.01, and p<0.05, respectively, and the absence of a symbol indicates p>0.05.
