Correlations between Different Measures of Visual Function

Foveal Motion Acuity	Foveal Motion Acuity	Motion Discrimination in Fovea	Motion Discrimination in Periphery	Multitarget Motion Comparison	Visual Crowding	Visual Search
Motion discrimination in fovea	0.59†
Motion discrimination in periphery	0.54	0.84§
Multitarget motion comparison	0.56*	0.77§	0.93§
Visual crowding	0.35	0.42	0.52	0.50
Visual search	0.65‡	0.38	0.66‡	0.76§	0.42
logMAR acuity	0.49	0.50	0.44	0.50	0.01	0.49

^Pvalues were Bonferroni corrected. For comparison, all correlations over 0.40 are significant at an uncorrected α of 0.05. Snellen acuity correlations were adjusted (increased) to account for the upper limit (r = 0.89) set by the semicategorical distribution of acuities (Table 1). Terms *, †, ‡, and § indicate corrected P values of 0.1, 0.05, 0.01, and 0.001, respectively.
