Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Group Polarization01:01

Group Polarization

39.3K
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Color Vision01:24

Color Vision

1.9K
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.

Group Design

11.0K
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

Bending of Members Made of Several Materials

In analyzing a structural member composed of two different materials with identical cross-sectional areas, it is crucial to understand how their distinct elastic properties affect the member's response under load. The analysis involves assessing stress and strain distributions using the transformed section concept, which accounts for variations in material properties.
Hooke's Law determines stress in each material, stating that stress is proportional to strain but varies due to each material's...

Changes in Skin Color: Clinical Perspectives

4.1K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Area of Science:

  • Cognitive Science
  • Linguistics
  • Psychology

Background:

  • Conceptual spaces provide a framework for representing meaning.
  • Kamp and Partee's account addresses graded membership within this framework.
  • The application of this account to the domain of color perception requires empirical validation.

Purpose of the Study:

  • To empirically test Kamp and Partee's account of graded membership.
  • To determine typical regions for blue and green in color space.
  • To assess human judgments of blueness/greenness in transitional color shades.

Main Methods:

  • Three experiments were conducted involving human observers.
  • Participants judged the degrees of blueness and greenness for various color shades.
  • Color regions for typical blue and green were mapped in conceptual color space.

Main Results:

  • Typical regions for blue and green were identified in color space.
  • Predicted degrees of blueness/greenness were derived from the conceptual spaces framework.
  • These predictions were compared with experimentally obtained human judgments.

Conclusions:

  • The experimental results provide support for Kamp and Partee's account of graded membership.
  • The conceptual spaces framework effectively models graded membership in the domain of color.
  • The study validates the use of this framework for understanding perceptual categories.
