pyschology visual perception Flashcards
(17 cards)
What is the cornea?
A clear, tough membrane that protects the eye and bends light into the lens
The cornea is the outermost layer of the eye and plays a crucial role in focusing vision.
What is the function of the lens?
Convex lens that focuses light onto the retina
The lens adjusts its shape to help focus on objects at various distances.
What does the iris do?
Colored part of the eye attached to muscles that control the size of the pupil
The iris regulates the amount of light entering the eye.
What is the retina?
Back surface of the eye covered in receptor cells called rods and cones
The retina is crucial for converting light into neural signals.
What is the role of the optic nerve?
Nerve that takes the visual signal to the brain
The optic nerve transmits visual information processed by the retina.
What is the pupil?
Opening in the eye that allows light to pass through
The size of the pupil changes in response to light levels.
What are rods?
Cells that can detect very dim light
Rods are more sensitive to light but do not detect color.
What are cones?
Cells that detect colors in bright light
Cones are concentrated in the fovea and are essential for color vision.
What is a blind spot?
The point at which the optic nerve leaves the eye, creating a ‘blind’ spot because no receptor cells are located there
The brain fills in this gap using information from the other eye.
What is the sclera?
White part of the eye
The sclera provides structure and protection to the eye.
What are the Aqueous Humour and Vitreous Humour?
Fluids in the eye for support and pressure
These humours help maintain intraocular pressure and provide nutrients.
What is the path of light through the eye?
Cornea, pupil, lens, retina (C-P-I-L-R)
This path is essential for visual processing.
What is visual perception?
Interpretation of visual stimuli by the brain
Visual perception involves recognizing and understanding what we see.
What is reception in the context of sensory information?
The process of detecting and responding to incoming sensory information (such as light)
Reception is the first step in the sensory processing pathway.
What is transmission in sensory processing?
The process of sending the sensory information to relevant areas
Transmission involves neural pathways that relay signals to the brain.
What is transduction?
Converts light energy that hits the retina into electrical signals that move along the optic nerve
Transduction is a critical step in transforming physical stimuli into neural signals.
What is interpretation in sensory processing?
The process that takes incoming sensory information and gives it meaning
Interpretation combines sensory input with existing knowledge and context.
