Presentation Transcript


Modules 12 – 15

  • We will split into 4/5 teams.

  • Each group will be given 10 X’s.

  • Your group will be given a question. Answer it right and you get to erase two X’s from other groups.

  • If you lose all of your X’s, your group is eliminated.

Grudge Rules

  • The chemical sense of smell is called this


  • Thin outer layer where light enters the eye.


  • The region of the ear that contains the stirrup.

Middle Ear

  • The only sense that doesn’t pass through the thalamus on its way to the brain.


  • The back part of your eye that contains rods and cones.


  • Messages that are below one’s absolute threshold.


  • Light rays focus in front of the retina and creates this type of vision problem.


  • This nerve carries neural impulses from the eye to the brain.

Optic Nerve

  • Focusing on one thing allows us to block out other things going on. (Gorilla Video)

Selective Attention

  • Central point of the retina where images focus.


  • Simultaneously analyzing different elements of sensory information such as color, brightness, shape, depth.

Parallel Processing

  • The idea that one sense may influence another sense is called:

Sensory Interaction

  • Our body’s sense that provides information about the position and movement of our body parts is called:


  • Color depends on context. Just because you change the background around a color doesn’t change the color.

Color Constancy

  • The sense of hearing is called this.


  • This Young-Helmholtz Trichromatic theory says that our retinas have these 3 types of color receptors.

Red, Blue, and Green

  • Light rays focus in back of the retina and creates this type of vision problem.


  • Colored ring of muscle, constricts or dilates depending on the amount of light.


  • This theory of pain states that messages must pass through the spinal cord to reach the brain.

Gate-Control Theory

  • These are 3 fluid filled bony channels in the inner ear that help maintain balance.

Semicircular Canals

  • Height of a wave.


  • The ability to focus on one voice in a room full of people.

Cocktail Party Effect

  • The highness or lowness of a sound.


  • Brightness of light


  • We become dizzy if the fluids in this part of our ear have not returned to normal.

Semicircular Canals

  • The amplitude of a sound wave determines this.


  • The distance from one wave peak to the next.


  • Shorter wavelengths produce __________ frequencies.


  • This theory states that opposing retinal processes enable color vision. Red & Green, Yellow & Blue, White & Black.

Opponent-Process Theory

  • Laser eye surgery in which a flap is cut into the cornea to access the tissue behind it.


  • These are measuring units for sound energy.


  • The region of the ear that contains the eardrum.

Outer Ear

  • The study of how physical stimuli are translated into psychological experience.


  • The five basic taste sensations are:

Sweet, sour, salty, bitter, and umami

  • These receptors detects color and allows you to see in bright light.


  • Transformation of stimulus energy (light, sound, etc.) to neural impulses our brains can interpret.


  • Taste receptors reproduce this often.

Every week or two

  • The region of the ear that contains the semicircular canals.

Inner Ear

  • These are chemicals released by animals to attract other animals.


  • Vibrations on this part of the cochlea causes movement of the fluids inside.

Oval Window

  • Point in your retina where there are no receptor cells.

Blind Spot

  • The basilar membrane is lined with these cells that move with vibrations from sound.

Hair Cells

  • Images the briefly appear after the actual image is removed.


  • Focuses the light rays onto the retina.


  • Theory in which we hear different pitches because different sound waves trigger activity at different places in the cochlea.

Place Theory

  • This is what our body does with the information we sense.


  • Theory in which we sense pitch at the same rate as the sound entering the basilar membrane.

Frequency Theory

  • These receptors detect black, white, and gray. They also allow you to see in low light.


  • This is the tight membrane at the end of the auditory canal that vibrates.


  • Diminished sensitivity because of constant stimulation. If I put a band aid on, after a while I don’t feel it.

Sensory Adaptation

  • In order to sense taste, molecules must be dissolved in this.

Saliva or other Liquid

  • The number of complete wavelengths that pass a point in a given amount of time.


  • This part of the tongue catches food chemicals.

Taste Buds

  • Prolonged exposure above this range produces hearing loss.

85 decibels

  • If you pierce your eardrum you may experience this type of hearing loss.


  • Sound messages travel through the thalamus to this part of the temporal lobe.

Auditory Cortex

  • The minimum difference between two stimuli that a person can detect.

Difference threshold

  • Damage to your cochlea can produce this type of hearing loss.


  • This part of the eye regulates the amount of light that comes in.


  • Somatosensation is the technical term for this sense.


  • The weakest level of a stimulus that can be detected 50% of the time.

Absolute Threshold

  • Touch is made up of these four skin senses.

Pressure, warmth, cold, and pain

  • This is the process by which you detect physical energy from your environment and encode it as neural signals.


  • Hyperalgesia is an increased sensitivity to this.


  • The color we see.


Gustation is the technical name of this sense.


  • The sharpness of vision
