The Basics
This is the science of defining quantitative relationships between physical and psychological events.
Psychophysics
This is the dark, circular opening at the center of the eye.
pupil.
Rods are specialized to help you see during this time of the day.
night/night vision.
This is the main object that is to be recognized in a figure-ground image.
Figure
This term refers to the failure to recognize objects visually in spite of the ability to see them
Object Agnosia
This method for testing subjects' perception in stimulus detection and difference detection requires the observer to alter the strength of a stimulus until it matches some criterion
Method of adjustment
This is the light-sensitive membrane at the back of the eye that contains rods and cones
retina.
These photoreceptors contribute to color vision
cones
When one object covers up another object, that is known as.....?
occlusion.
This type of processing involves individual elements of a stimulus combined into a unified perception.
What is bottom -up processing?
The psychophysical method in which stimuli of varying intensities are presented in ascending and descending orders in discrete steps is called the method of…
What is the method of limits?
The right visual field projects to this half of each eye.
What is the left?
Rods are most highly concentrated in this area of the retina
Periphery
This Gestalt grouping principle suggests that elements that look alike tend to be seen as grouped together
Similarity
This term refers to an individual who cannot identify faces, but can recognize other types of objects.
Prosopagnosia
A psychophysical technique where a researcher presents a set of different stimulus intensities to a participant in a random order, and asks them to judge whether they perceive the stimulus or not, allowing for a precise measurements.
What is the method of constant stimuli?
This is the name of the area where the optic nerve leaves the eye.
What is the blindspot?
Cones are most highly concentrated in this area of the retina
fovea
This Gestalt grouping principle suggests that elements that are close to each tend to be seen as grouped together
Proximity
What is the name of the area in the temporal lobe that specializes in recognizing faces?
What is the fusiform face area (FFA)?
This is the smallest detectable difference between two stimuli
just noticeable difference
This type of mapping is an orderly mapping of the world in the LGN (thalamus) and visual cortex.
retinotopic mapping
Each cone is connected to 1 of these cells, creating high spatial resolution/acuity.
What is retinal ganglion cells?
The Gestalt principle that suggests elements moving in the same direction are perceived as part of a single group.
What is Gestalt's Law of Common Fate?
The ventral stream travels from V1 to part of the cortex (lobe).
What is the the temporal cortex?
This pathway cares about what objects are.
