Table 1.

Linear regression models including individual runs of the figure-ground discrimination tasks as variables.

Variable 1	Variable 1 r-value	Variable 2	Variable 1 + 2 r-value	r2 change	p change
Same-frequency (R1)	0.30	Same-frequency (R2)	0.32	0.02	0.21
Same-frequency (R2)	0.28	Same-frequency (R1)	0.32	0.03	0.10
Same-frequency (R1)	0.30	Coherent roving (R1)	0.40	0.07	0.006**
Same-frequency (R2)	0.28	Coherent roving (R1)	0.40	0.08	0.004**

The table displays r-values associated with a model including variable 1 only, a model including variables 1 and 2 together, and the r² change and p-values associated with adding the second variable to the model (**p < 0.01). R1: run 1; R2: run 2.
