Week 4 Flashcards
determined that something like half the brain is dedicated to visual recognition and that how and what we see is tied up with our physiological structure.
Modern Nuerophysiology
It focuses the image on the retina just as the camera focuses an image on film.
Eye
It organizes the material which has been focused on it by using its photoreceptors (light sensitive cells)
Retina
processing dim light
Rods
processing color and bright light
Cones
transform what we have ‘captured’ visually into recognizable objects, and it is not until this work is completed that the image goes to the brain via the optic nerve to be processed further there
Photoreceptors
The ___________ is very physical- eyes are focusing on objects
Process of Visual Perception
processing matter
Rods and Cones
transporting the images they have recorded
Optical Nerve
He wrote that seeing is an activity that is ultimately derived from touching.
Sigmund Freud
He used the analogy of feeling one’s way through the world, but he did not assume that seeing depended only on a sensory experience.
René Descartes
He insisted that our senses are inadequate for perception we need to make sense of what we see using rational thought
René Descartes
What are the Visual Perceptual Processing Categories
Visual Discrimination
Visual Figure Ground
Visual Closure
Visual Memory
Visual Sequential Memory
Visual Form Constancy
Visual Spatial Relationships
the ability to be aware of the distinctive features of forms including shape. orientation, size, and color.
Visual Discrimination
is the ability to distinguish an object from irrelevant background information
Visual Figure Ground
is the ability to recognize a complete feature from fragmented information.
Visual Closure
is the ability to retain information over an adequate period of time.
Visual Memory
is the ability to perceive and remember a sequence of objects, letters, words, and other symbols in the same order as originally seen
Visual Sequential Memory
is the ability to recognize objects as they change size, shape, or orientation
Visual Form Constancy
refer to the ability to understand directional concepts that organize external visual space.
Visual Spatial Relationship
These are rules that describe how the human eye perceives visual elements
Gestalt principles or laws
