These cells, shown above, are in the Lateral Geniculate Nucleus.
What are Cone Opponent Cells?
Painters use this contrast technique to give mountain ranges in the distance a sense of distance.
What is the Atmospheric perspective?
or
What is Aerial perspective?
In a simple feature search, reaction time remains constant (RT 0) regardless of the number of distracters since the target "pops out" because of this characteristic.
What is salience?
This is a powerful illusion of motion in the visual image caused by prior exposure to motion in the opposite direction
What is motion aftereffect?
These psychologists emphasize that the perceptual whole is greater than the sum of its parts.
What are gestalt psychologists?
or
Who are gestalt psychologists?
As the brightness of a color increases or decreases, this property of color—related to its purity—also tends to decrease.
What is saturation?
These are both oculomotor depth cues.
What are accommodation and convergence?
This type of search takes people more and more reaction time as the number of features increase.
What is conjunction search?
This visual challenge occurs when only part of a moving object is visible, making it difficult to perceive its true motion.
What is the aperture problem?
The axons of these cells leave the eye via the optic nerve and transmit information to the brain and midbrain.
What are Ganglion Retinal Cells?
or
What are ganglion cells?
Any pair of stimuli perceived as matching in color, but having different (nonmatching) spectral power distributions.
What are metamers?
While walking past a fence, nearby objects like fence posts seem to move quickly across your field of vision, while distant buildings appear to move much slower. This phenomenon helps provide depth information.
What is motion parallax?
This type of attention impairs performance when trying to focus on multiple tasks at once, regardless of how much practice you have.
What is Divided Attention?
This aspect of optical flow remains stationary while everything else moves.
What is Focus of Expansion?
If you had a stroke that damaged your inferior frontal lobe, this sense would be most likely to be impaired.
What is smell?
This principle explains why a single photoreceptor cannot differentiate between changes in intensity and changes in wavelength, leading to color vision deficiency if only one type of cone is available.
What is the Principle of Univariance?
In a random dot stereogram, this process allows you to perceive depth by matching points between the two retinal images.
What is correspondence matching?
or What is correspondence point matching?
You are focused on organizing your papers on your desk into seperate piles, and you fail to notice a mouse on a nearly empty plate that is clearly visible. This is an example of
What is inattentional blindness?
In a study on motion perception, monkeys with lesions to this brain area required ten times as many dots in a correlated dot motion display to correctly identify motion direction.
What is the MT (middle temporal) area?
In these types of studies sections of the brain are surgically excised to see how it affects behavior.
What are brain lesion studies?
or
What are lesion studies?
This is a graph of the energy levels of a light source through a range of wavelengths of light.
What is Spectral Power Distribution? or What is the Distribution of Spectral Density?
The region of space, in front of and behind the horopter, within which binocular single vision is possible.
What is the Panum's Fusional Area?
Initiating and guiding reflexive eye movements are controlled mainly by this brain structure.
What is the Superior Colliculus?
This mechanism adjusts the timing of signals from the first receptive field so that it aligns with the input from the next receptive field, allowing motion detection cells to accurately respond to sequential activation in a particular direction.
What is the delay mechanism?
or What is the delay?
This term refers to the fact that striate cortex neurons tend to respond more strongly to stimuli presented in one eye as compared to the other
What is ocular dominance?
