Study material for quiz 6

Sensation

The process in which our body and nervous system recieve input from the environment.

Transduction

Changing of one form of energy to another. This occurs in the eye, we’re only percieving the light.

Wavelength

Distance from one wave peak to another.

Intensity

Amount of energy - measured by amplitude

Photoreceptor

Cells that transform light energy into electrochemical light.

Hue

The colors we percieve

Visible Spectrum

What colors are visible with the human eye. This is different for animals.

Peripheral Vision

The optical ability to see items directly beside the body.

Blind spot

Area in the eye where there are no ganglion cells formed so you can’t see pictures.

Saccade

Rapid eye movement from side to side

Dark Adaptation

The optical ability to let in more light in darkly lit areas to see in the dark.

Parallel Processing

The brains ability to do many things at once like percieve color, speed, and images.

Trichromatic Theory (Young-Helmholtz)

You can only see color in the visible spectrum

Opponent Process Theory

Certain colors are associated with each other and will excite one another. For example looking away from something red you’ll see blue.

After Image

Visual stimulation that after looking at an image you can see it on a clean white space as well.

Color blindness

The inability to seperate colors and tell them apart.

Audition

How your ears process sound

Amplitude

Height of sound waves and quality of sound.

Pitch

Auditory notes

Frequency

Number of wavelengths in a cycle

Place theory

highest/lowest pitched sounds excite the cochlea.

Frequency Theory

As pitch rises, the basilar membrane vibrates which enables us to percieve sound.

Conductive Hearing Loss

Poor transfer of sounds through the tympanic membrane.

Nerve Deafness

Damage to the auditory nerve in the auditory canal.

Cochlear implant

Surgical implant of electrodes in the ear to promote sound perception.

Sensorineural Hearing Loss

Damage to the inner ear of the auditory nerve.

What order does the eye percieve light?

Cornea>Pupil>Lens

Cones

Percieve color

Rods

Percieve nightime vision.

Olfactory Sense

Your smell, receptors in the nasal cavity respond to gaseous molecules.

Taste

Papillae on your tongue have taste receptors.

Touch

Your somesthetic senses allow us to feel temperature and pain.

Kinesthesis (Movement)

Your muscles and tendons have responses that form movement.

Proprioception

Sense of your body in space

Synesthesia

When one sense is triggered it also triggers another.

McGurk Effect

An illusion when auditory component is paired with visual components

Multimodel perception

Your senses evolved together and tandemly.
