What is the Trichromatic vision theory?

• All of our color vision comes down to three different types of cones, which are activated by multiple wavelengths of light

• All of our color vision comes down to three different types of cones, which are activated by one single wavelength of light, but in different amounts

• All of our color vision comes down to four different types of cones, which are activated by one single wavelength of light, but in different amounts

• All of our color vision comes down to four different types of cones, which are activated by multiple wavelengths of light

Why does color blindness occur?

• Excessive exposure to intense colors

• Excessive exposure to bright colors

• The cones aren't functioning properly

• The rods aren't functioning properly

Cone-rod dystrophies is vision loss over time resulting from deteriorating cones and rods.

What are some symptoms?

• Increased light sensitivity

• Blind spots in the center of the vision

• Loss of color perception

• Loss of peripheral vision

What is true of Bottom-up processing?

• Purely data-driven, requires no previous knowledge or learning

• You perceive things based on your prior experiences and knowledge.

• Sensory analysis that begins at the entry level - With what our senses can detect

What is kinesthesia?

• Kinesthesia is the perception of colors.
• Kinesthesia is the perception of taste.
• Kinesthesia is the perception of body movements.
• Kinesthesia is the perception of sound.

What is vestibular sense?

• Vestibular sense is the sense of taste and smell.
• Vestibular sense is the sense of body movement and position, including the sense of balance.
• Vestibular sense is the sense of hearing and vision.
• Vestibular sense is the sense of touch and temperature.

How is vestibular sense achieved?

• Vestibular sense is achieved through the auditory system.
• Vestibular sense is achieved through the visual system.
• Vestibular sense is achieved through the movement of fluids located in the inner ear.

• Vestibular sense is achieved through the olfactory system.

What are the 2 functions of ears?

• Hearing and balance
• Breathing and speaking
• Seeing and touching
• Smelling and tasting

Auricle, External acoustic meatus, Tympanic membrane (eardrum) are associated with which part of the ear?

• Middle Ear
• Inner Ear
• Cochlea
• Outer Ear

What does the Auricle/Pinna do?

• Emits sound waves
• Senses the movement of fluids and gives info about the acceleration

• Amplifies sound waves so they are strong enough to move through the fluid in the inner ear

• Catches sound waves and directs them deeper into the ear
