Color-matching functions, as well as the variances and inter- and intra-individual correlations, are given for ten subjects. The dispersion found in the blue region is greater than that indicated by Stiles and Burch. The color-matching tech...

Equations are derived to fit the cone sensitivity values of Smith and Pokorny, which are based mainly upon Judd's modified color matching functions and the spectral sensitivities of normal and dichromatic observers. The equations, which fit...
Contrast masking in human vision [0.03%]
G E Legge,J M Foley
G E Legge
Contrast masking was studied psychophysically. A two-alternative forced-choice procedure was used to measure contrast thresholds for 2.0 cpd sine-wave gratings in the presence of masking sine-wave gratings. Thresholds were measured for 11 m...
Two-pulse discrimination and rapid light adaptation: complex effects on temporal resolution and a new visual temporal illusion [0.03%]

R W Bowen
Temporal resolution during rapid light adaptation was studied using a suprathreshold two-pulse discrimination paradigm with stimulus conditions modeled after the classic increment threshold experiments of B. H. Crawford. The two-pulse stimu...

Localization of single stimuli presented individually on the circumference of an imaginary circle was determined with and without three diopters of refractive error introduced by spherical lenses. The presence of blur had no effect on local...

Changing-size channels tuned to the oscillation frequency are excited by a stimulus square whose size oscillates at a fixed frequency. In the 0.25-16 Hz frequency band there are at least three kinds of changing-size channels tuned to differ...
