Abstract |
Large effects of increase in intensity in the lower part of the intensity scale are obtained, and the speed of discrimination is higher for the large than the small angles and for the large than the small coefficients of reflection between object and background, for light test objects on dark grounds. The amount of effect is greater for light objects on dark grounds than for the reverse case. (PsycINFO Database Record (c) 2012 APA, all rights reserved) |
