Chromatic valence curves: alternative interpretation derived by the direct matching method
Science (New York, N.Y.)
|March 19, 1982
Summary
The human visual system
Area of Science:
- Visual perception
- Color vision science
- Human visual system
Background:
- Previous studies indicated reduced red chromatic valence at short wavelengths using the hue-matching method.
- A 'silent surround' hypothesis was proposed to explain this valence reduction.
Purpose of the Study:
- To re-evaluate the cause of reduced red chromatic valence.
- To determine if existing color-matching data can explain the phenomenon without new hypotheses.
Main Methods:
- Analysis of previous experimental results.
- Interpretation of data within the framework of established color-matching principles.
Main Results:
- The observed reduction in red chromatic valence is an artifact of the hue-matching method and specific stimuli used.
- Existing color-matching data adequately explain the valence reduction.
Conclusions:
- The 'silent surround' hypothesis is unnecessary to explain the reduced red chromatic valence.
- Methodological factors, not a novel visual system feature, account for the previous findings.

02:42Valence Bond Theory
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...
01:32UV–Vis Spectroscopy of Conjugated Systems
Organic compounds with conjugated double bonds show strong absorption features in the UV–visible region of the electromagnetic spectrum attributed to π → π* electronic excitations. Generally, a UV–vis absorption spectrum is recorded as a plot of absorbance vs wavelength. The wavelength of maximum absorbance, which manifests as a peak in the absorption spectrum, is denoted as λmax.
One of the factors influencing λmax is the extent of conjugation in the...

01:29UV–Vis Spectroscopy: Woodward–Fieser Rules
UV–Visible absorption spectra of conjugated dienes arise from the lowest energy π → π* transitions. The light-absorbing part of the molecule is called the chromophore, and the substituents directly attached to the chromophore are called auxochromes. A strong correlation exists between the absorption maxima, λmax, and the structure of a conjugated π system. The Woodward–Fieser rules predict the value of λmax for a given structure by adding the contributions...
01:10Calibration Curves: Correlation Coefficient
In a linear calibration curve, there is a value called the calibration coefficient, denoted by 'r,' which measures the strength and the direction of association between two variables. The correlation coefficient value ranges from −1 to +1. A value of +1 indicates a perfect positive linear correlation, −1 denotes a perfect negative correlation, and 0 implies no correlation between the two variables. A positive correlation value establishes that as one variable increases, the other increases, and...
01:24Color Vision
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.
