How Much Pigment Should Flowers Have? Flowers With Moderate Pigmentation Have Highest Color Contrast
Frontiers in Ecology and Evolution, 2021 Floral pigments are a core component of flower colors, but how much pigment a flower should have to yield a strong visual signal to pollinators is unknown.

Acuity and contrast sensivity of infant vision
Nature, 1974 IF we are to study the development of form and space perception in man, it is necessary to know something of the basic visual capabilities of the developing human infant. There have been a number of investigations of visual acuity in the first few months of life.

A Critical Analysis on Perceptual Contrast and Its Use in Visual Information Analysis and Processing
IEEE Access, 2020 Contrast in visible images is one of the most relevant characteristics of visual signals. Since the pioneering works performed in vision psychology and optics, different definitions have been proposed in the literature.

Assessing the monitor warm-up time required before a psychological experiment can begin [PDF]
Tutorials in Quantitative Methods for Psychology, 2017 Visual experiments in psychology, psychophysics, and cognitive neuroscience require precise control over stimulus characteristics, such as luminance and contrast. In such experiments, stimuli are most often presented using computer monitors.

Effects of Contrast Sensitivity on Colour Vision Testing [PDF]
Neuro-Ophthalmology, 2017 This study analyses how contrast sensitivity loss affects colour vision (CV) testing. Eleven participants were scored while cycling through randomly arranged pictures of CV tests with varying levels of contrast changes applied. Hardy-Rand-Rittler (HRR) scores declined significantly at each successive decrease in contrast level after the highest setting

Improving iconic memory through contrast detection training with HOA-corrected vision
Fundamental ResearchIconic memory and short-term memory are not only crucial for perception and cognition, but also of great importance to mental health. Here, we first showed that both types of memory could be improved by improving limiting processes in visual processing ...
