Orientation discrimination across the visual field: matching perceived contrast near threshold
Performance can often be made equal across the visual field by scaling peripherally presented stimuli according to F=1+E/E2 where E2 is the eccentricity at which stimulus size must double to maintain foveal performance levels. Previous studies suggest that E2 for orientation discrimination is in the range of 1.5 degrees -2 degrees when stimuli are presented at contrasts well above detection thr...
متن کاملWavelength discrimination by the goldfish near absolute visual threshold.
Goldfish were classically conditioned to discriminate between 532 nm and 635 nm lights while light adapted, and then tested for their ability to continue the dis~mjnation as the intensities were reduced. In all tests, the two stimuli were balanced for effectiveness at absolute threshold. We find that goldfish can discriminate between these wavelengths about I log unit above absolute threshold. ...
متن کاملContrast-dependent orientation discrimination in the mouse
As an important animal model to study the relationship between behaviour and neural activity, the mouse is able to perform a variety of visual tasks, such as orientation discrimination and contrast detection. However, it is not clear how stimulus contrast influences the performance of orientation discrimination in mice. In this study, we used two task designs, two-alternative forced choice (2AF...
متن کاملContrast amplification in global texture orientation discrimination.
We show that adding a low-contrast texture stimulus that is far below its own detection threshold to an ambiguously oriented high-contrast texture can produce an easily perceived global orientation. When such a low-contrast (e.g., 0.1%) test texture and a high-contrast (e.g., 2%) amplifier texture are interleaved, the effective strength for global orientation detection closely approximates the ...
متن کاملColor-weak correction by discrimination threshold matching
The correction of the effects of color-weakness is difficult if not impossible. One of the reasons is that are no objective criterions available to evaluate corrections since it is difficult to quantify the color perception of an individual. Also the degree and the character of color-weakness vary widely among individuals and different color stimuli. In this paper, we use Riemann geometry to co...
