The retina is a region that contains photoreceptors that convert light into electric impulses, which are sent into the optic nerve by using rods and cones.

The retina is the red, internal region of the eye that converts light into electric impulses, in which rods and cones extract visual information and transfer it to the retina to maintain a continuous image.

The optic nerve is a bundle of nerves that carry visual information from the eye, sending that information to the visual cortex, the back of the brain, in which the visual cortex makes sense of the visual information from the optic nerve.

The optic nerve is a bundle of nerves that extracts information from the visual cortex, the back of the brain transferring that data into the eyes.

The optic chiasma is the region where both optic nerves cross over. The optic nerves switch places, transferring information from one another, flipping images back right side up after the lens refracts and makes images upside down

The optic chiasma is the region where both optic nerves cross over. The optic nerves are then bundled up into a helix, allowing information to be evenly distributed and shared. This ensures that upside down images are flipped right side up.

True

False

Using both eyes and making a hole with your hand, looking at the hole from the centre and closing one eye at a time indicates which eye is the dominant eye depending on how well each eye can see through the hole.

The dominant eye only requires one eye. This is because even if you have two eyes, when you have one eye, your brain will automatically assign that one eye as the dominant eye.

There are 64 student participants which are a grouped sample.

There are 64 student participants across 3 different schools, coming from Grammar, Secondary, and Technical schools, which are evenly distributed across to create a matched sample.

Participants observe a photo of a kitchen for 2 seconds. After this, participants are then given a choice as to what they saw. They chose from: Bread, Mailbox, or Drum.

Participants observe a photo of a kitchen for 2 seconds. After this, participants are then given a choice as to what they saw. They chose from: Toaster, Chopping board, and Drum.

The conditions of the experiment were:
- Chose an object with an appropriate context and shape
- Chose an object with an innapropriate context, but has a similar shape
- Chose an object with an innapropriate context and different shape
- No interpretation given.

The conditions of the experiment were:
- Chose bread or toaster
- Chose mailbox or chopping board
- Chose drum
- No interpretation given.

Many of the participants were able to choose the correct object, the toaster. This is because they were given the schema of a kitchen, so what they often chose was an object with an appropriate context and shape.

Many of the participants chose the bread. This is because they were given the schema of a kitchen, so what they often chose was an object with an appropriate context and shape.

Lab experiment

Quasi experiment

This type of experiment allows for high levels of control, so the experiment can be fairly measured and tested for reliability.

This type of experiment used a natural experiment, which means that it very high amounts of realism.
