Flicker photometry experiment
|
|
Flicker photometry experiment Stimuli consisting of a pair of different color test lights alternate. When the lights alternate slowly the pattern appears to change between the colors of the two lights. When the lights alternate rapidly observers fail to see the color modulation and instead perceive a dark-light modulation. Demonstrates that the temporal resolution for distinguishing blue-yellow is less than red-green which in turn is less than light-dark.
RELATED TERMS--------------------------------------
Temporal
Having to do with the side of the head.
SIMILAR TERMS--------------------------------------
Flicker
Alternating levels of brightness.
PREVIOUS AND NEXT TERMS--------------------------------------
Filling-In theory
Idea that the brightness and color of interiors of homogeneous regions are determined by a process of lateral spread of neural activation that is initiated by units responding to abrupt changes in luminance and wavelength.
First-Order statistics
Captures differences in overall brightness.
First-Order motion mechanisms
Captures motion information from moving objects or features that differ from the background in luminance.
Fixation
Alignment of the eyes so that the image of the fixated target falls on the area centralis. For animals with immobile eyes the alignment of the head towards the fixated target.
Flicker
Alternating levels of brightness.
Flicker photometry experiment
Floater
A blurry spot that appears to float around in the eye but does not block vision. The blur is the result of debris from the vitreous humour casting a shadow on the retina.
Focal length
Relates the distance between an image source and a lens and the distance of the lens to the image by the lenses focal length.
Focal vision
The role of vision involved in the examination and identification of objects associated with the fovea and exploratory eye movements.
Foveola
The center of the fovea.
Full-Wave rectification
A signal which shows a positive response to both the positive and negative parts of a sinusiod (i.e. frequency doubling). Many complex cells show this to contrast reversing patterns.
