Vision
Describe the 2 photoreceptors on the retina & their functions

Cones - colour & vision in bright lighting
Compare the amplitude of the door gently closing vs a baby screaming
The amplitude of the door closing will be smaller/lower than the baby screaming & vice versa
Not being able to taste your favourite food when you’re sick is an example of ______________________ between gustation and olfaction.
Sensory interaction
Compare texture gradient to relative clarity
Texture gradient: Close objects appear to have more detail
Relative clarity: Objects in the distance appear less clear/more blurry; objects that are closer appear clear/sharp
Where transduction occurs in the eye
Retina
Describe the three opposing colour pairs in the opponent process theory of colour:
green/red, blue/yellow, black/white
The retina is to the eye as the _______________________ is to the ear
(HINT - Not the cochlea)
Basilar Membrane
Jeremy takes the supertaster test and notes that some of the strips taste extremely bitter to him.
What sensory nerves are responsible for this, and what does this suggest about their concentrarion?
Papillae (taste buds) – Jeremy has a high concentration of papillae
Bailey is given a piece of candy and told that it tastes strongly of lemon. When she eats it, she thinks it’s lemonade flavoured when in reality it’s orange. What kind of processing is this an example of?
Top-Down Processing
Not noticing the number of potato chips slowly decreasing as the size of the packaging gradually becoming smaller is an example of which threshold?
Difference threshold
Nancy has a type of colour-blindness where she can see shades of red and green, but can not recognize shades of blue. What kind of colour blindness is this, and which receptors are lacking?
Dichromatism (lacking blue receptors)
Explain the place theory of pitch
Perception of pitch corresponds to the vibration of different portions, or locations/places, along the basilar membrane.
What are the 6 tastes that our taste buds can sense?

Perceptual set
When looking at a face, you recognize the edges, lines, and angles of the face before recognizing the face as a whole. What cells are responsible?
Feature detectors
Place the following in order of processing:
Photo receptors, Ganglion cells, Light waves, Bipolar cells, optic disk
Light wave → photoreceptors → bipolar cells → ganglion cells → optic disk
Where does transduction occur in the auditory process?
Cochlea
______________ are the sensory receptors in the nose, and they send direct signals to the _____________________.
Cilia (hairs cells) & Olfactory Bulb
Define and provide and example of Retinal disparity
Two eyes receive different images, closer objects receive more different images while objects further away are more similar in image
