1.6 Sensation

Vestibular Sense

• The sense of taste and flavor perception.

• The sense of body movement and position, including the sense of balance.

• The sense of sight and visual perception.

• The sense of hearing and auditory perception.

Opponent-Process Color Theory

• The theory that color vision is a result of the mixing of primary colors.

• The theory that opposing retinal processes (red-green, yellow-blue, white-black) enable color vision.

• The theory that color perception is solely based on the wavelength of light.

• The theory that color vision is determined by the intensity of light received.

Light/Dark Adaptation

• The process by which the eyes become more sensitive to light in low illumination.

• The process of adjusting the brightness of a screen based on ambient light.

• The ability to see colors in low light conditions.

• The mechanism by which the eyes focus on distant objects.

Supertasters, Medium Tasters, Nontasters

• Categories of people based on their sensitivity to taste.

• Types of food preferences among individuals.

• Different cooking methods used in cuisine.

• Levels of spiciness in food.

Transduction

• The process of converting one form of energy into another.

• The ability to perceive stimuli through the senses.

• The method by which the brain stores memories.

• The act of interpreting neural impulses as sensations.

Lens

• The transparent structure behind the pupil that changes shape to help focus images on the retina.

• A colored part of the eye that controls the amount of light entering.

• The outer layer of the eye that provides protection and structure.

• A fluid-filled space in the eye that helps maintain its shape.

Chemical Senses

• The senses of taste and smell, which detect chemicals in the environment.

• The senses responsible for detecting light and sound.

• The senses that allow us to feel temperature and pressure.

• The senses involved in balance and spatial orientation.

Semicircular Canals (cochlea)

• Structures in the inner ear involved in maintaining balance.

• Parts of the outer ear that collect sound waves.

• Components of the middle ear that amplify sound.

• Nerves that transmit auditory signals to the brain.

Blind Spot

• The area of the retina where light is focused.

• The point at which the optic nerve leaves the eye, creating a 'blind' spot because no receptor cells are located there.

• The part of the eye responsible for color vision.

• The region of the eye that contains the most photoreceptor cells.

Wavelengths (pitch)

• The frequency of a sound wave

• The distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.

• The amplitude of a sound wave

• The speed of sound in air
