Perceptual Constancy01:12

Perceptual Constancy

1.7K
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

Position-effect Variegation

7.2K
In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

Changes in Skin Color: Clinical Perspectives

4.0K
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...

Background and Environment Affect Phenotype

7.9K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Difference from Background: Limit of Detection

8.7K
The limit of detection (LOD) is the smallest amount of analyte that can be distinguished from the background noise. The LOD value corresponds to the concentration at which the analyte signal is three times larger than the standard deviation of the blank signal. Below this value, the analyte signal cannot be differentiated from the background noise. It is calculated by dividing the calibration slope by 3 times the standard deviation of the blank signals.
The LOD indicates the presence or absence...

Phase Contrast and Differential Interference Contrast Microscopy

14.8K
Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

Summary

Perceived glossiness is influenced by surrounding colors, even when participants try to ignore them. This study shows contextual effects impact gloss perception on bicolored surfaces.

Area of Science:

  • Visual perception
  • Psychophysics
  • Color science

Background:

  • Glossiness is a material property independent of color.
  • Perceived glossiness is affected by highlight contrast.
  • Previous studies focused on gloss perception of unicolored surfaces.

Purpose of the Study:

  • Investigate contextual effects on gloss perception.
  • Determine if surrounding colors influence gloss judgments.
  • Examine gloss perception on bicolored surfaces.

Main Methods:

  • Participants judged glossiness of bicolored surfaces (real and photographic).
  • Tested influence of a second color on gloss perception.
  • Participants were instructed to ignore the second color.

Main Results:

  • Perceived glossiness was influenced by the second color on bicolored surfaces.
  • Contrasting contextual effects were observed.
  • When asked for global gloss, both colors were equally considered.

Conclusions:

  • Contextual color significantly influences gloss perception.
  • Gloss perception is not solely based on local surface properties.
  • Future research should explore color interactions in gloss perception.
