PSYC2020 Quiz 2: Lecture 5: Slides 1-9

What is the first structure light (a.k.a. Electromagnetic radition) hits when entering the eye?
Cornea
Cochlea
Retina
Pupil
70% of focusing is done by the pupil
True
False
False. 70% of the focusing is done by the cornea.
False. 70% of the focusing is done by the cornea.
The Fovea is... (numerous answers)
A layer of gelatenous fluid light has to pass through to get to the optic nerve
The area where retinal cones are particiculary concentrated.
The area where visual acuity is highest.
Where most of the focusing occurs.
The lens is...
A fine tuning mechanism that aids in focusing objects that are closer and father away
The structure that helps protect our eyes from UV rays.
It is the structure responsible for low light conditions and helps us see in the dark
Where you get the highest resolution.
As you get older the lens of your eye stiffens, making you either perminantley near or far sighted.
True
False
True. Depending on what state the lens stiffens at (thin state {far sighted} or thick state {near sighted}) determines whether you become permanently near sighted or far sighted.
True. Depending on what state the lens stiffens at (thin state {far sighted} or thick state {near sighted}) determines whether you become permanently near sighted or far sighted.
The Retina is where... (numerous answers)
Photo sensitive cells are.
Visual acuity is at its highest.
Light transforms into neurological impulses.
Where axons from the ganglain cells leave the eye.
The 'Blind spot' in the eye is also known as the...
Optic disk
Retina
Fovea
Cornea
The first recognisable 'eye' in evolution couldn't see but was more of a light detector.
True
False
True. The first identifiable 'eye' was created in the Hagfish more than 50 million years ago. The eye itself was covered by translucent skin and no image was reflected onto the retina but it could detect light. This light detection helped with the Hagfish's Cercadian Rythmn.

Before light gets to the con and rod receptors it has to pass through...
Ganglian cells, Amacrine cells, Bipolar cells & Horizontal cells.
Amacrine cells, Ganglian cells, Bipolar Cells & Horizontal cells.
Bipolar cells, Ganglian cells, Amacrine cells & Horizontal cells
Horizontal cells, Ganglian cells, Amacrine cells & Bipolar cells.
Evolution is a tinkerer, and although the human eye may be 'state of the art' in evolutionary mechanisms, it definitely doesn't represent the most optimal route to the light receptors on the retina. Better designs can be found in the camera of your smartphone.

The (x) is the solution to the "inside out" design of the retina.
Fovea
Cornea
Pupil
Optic nerve
The layer of cell bodies (Ganglian cells, Amacrine cells, Bipolar cells & Horizontal cells) thins out around the fovea, therefore light can hit the fovea directly, allowing for higher visual acuity (higher resolution).

What are the two types of photo recpetors in the retina?
Rod receptors
Cone recpetors
Pyramidal receptors
Cylinder receptors
There are three different types of cones, coded for blue light, red light & green light, they are responsible for colour vision.
True
False
Rods are able to pick up both colour and brightness.
True
False
False. Rods are only responsible for coding brightness (black and white).
False. Rods are only responsible for coding brightness (black and white).
The fovea is exclusivley populated by rods.
True
False
False. The fovea is only populated by cones. However, cones are not just in the fovea they are also distributed along the rest of the retina alongside rods.
False. The fovea is only populated by cones. However, cones are not just in the fovea they are also distributed along the rest of the retina alongside rods.
In the periphery of vision, rods far outnumber cones.
True
False
Cones do not share connection to the visual cortex with any other cones, this is called...
Low convergence
High convergence
Rods share connection to the visual cortex with several other rods, this is called...
High convergence
Low convergence
Low convergence in the cone cells results in..
Lower sensitivity, higher positional acuity
Higher sensitivity, lower positional acuity
Higher sensitivity, higher positional acuity
Lower sensitivity, lower positional acuity
High convergence in the rod cells results in...
Higher sensitivity, lower positional acuity
Lower sensitivity, lower positional acuity
Lower sensitivity, higher positional acuity
Higher sensitivity, higher positional acuity
Cones have a high spatial certainty, they know exactly where light is coming from. Rods have low spatial certainty. Rods have high sensitivity to low light. Cons have a low sensitivity to low light.

NOTE: We measure size and eccentricity (distance to left or right in visual space) in degrees of visual angle because the physical size of an object or the lateral separation of two objects does no tell us how big or separated they will be on the retina.
We're interested in what information is available to your brain, and all the information your brain has about the visual scene is contained in the retinal image (not in physical space).
