Objects
In figure-ground segregation, we tend to perceive the (object of regard) _______ to be the thing on top of, or in front of, the _______.
What is figure/ground?
This theory proposes that color vision is based on there being three elements in our visual system that respond differently to different wavelengths.
What is Trichromatic Theory?
This is an illusion whereby one moving object may cause another object to look as if it is moving
What is induced motion
This part of the brain is critical for this perception in the brain?
What is V5(MT)?
This type of processing is data driven and uses the physical stimuli influence how we perceive them.
What is bottom-Up
Three dimensions of the color experience.
What are Hue, Saturation & Brightness
A visual cue that occurs when one object partially hides or obstructs the view of a second object
What is Occlusion
Rapid, conjugate, eye movements that shift the center of gaze from one part of the visual field to another.
What are saccades?
Two important principles in perceptual organization.
What is grouping and segregation
These are the opposing colors according to the opponent process theory.
Blue/Yellow
Red/Green
Black/White
The difference in the location of a feature between the right eye's and left eye's image
What is Binocular disparity
Neurons that respond during performance and observations of the same action.
What are Mirror neurons?
Top down processing uses this about to influence how we perceive different things.
What is our existing knowledge
Our ability to perceive the color of an object despite changes in the amount and nature of illumination.
What is color constancy?
Cues based on the ability to sense the position of our eyes and the tension in the eye muscles
What are Oculomotor Depth Cues
The superior temporal sulcus (STS) is critical for this type of motion.
What is biological?
Names of Gestalt Principles that we use to group things? (7 Discussed in lecture)
The firing of receptor activity in response to red would be greatest in this cone
What is the long cone?
(still receiving info from S & M cones, however it is strongest for the long wavelength cones)
Depth cues that are associated with the changes made in the shape of the lens as they bring objects into focus
Accommodation and convergence
Explain the stream that moves visual information from V1 to the parietal lobe.
AND
the stream moves information from the V1 to the temporal lobe.
what are each of these referred to as?
Dorsal stream - V1 --> parietal lobe (WHERE)
Ventral stream - V1 --> temporal lobe (WHAT)
People with this e.g. (Oliver Sacks) fail to recognize specific faces.
What is Prosopagnosia. Damage to the FFA (Fusiform Face Area)
