Grudge Modules 12 – 15

Grudge Rules 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 Olfaction

Thin outer layer where light enters the eye. Cornea

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. Smell

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

Messages that are below one’s absolute threshold. Subliminal

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

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 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. Fovea

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: Kinesthesis

Color depends on context 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. Audition

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. Farsightedness

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

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. Amplitude

The ability to focus on one voice in a room full of people. Cocktail Party Effect

The highness or lowness of a sound. Pitch

Brightness of light Intensity

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. Loudness

The distance from one wave peak to the next. Wavelength

Shorter wavelengths produce __________ frequencies. Higher

Opponent-Process Theory 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. LASIK

These are measuring units for sound energy. Decibels

The region of the ear that contains the eardrum. Outer Ear

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

Sweet, sour, salty, bitter, and umami The five basic taste sensations are: Sweet, sour, salty, bitter, and umami

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

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

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. Pheromones

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. Afterimages

Focuses the light rays onto the retina. Lens

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. Perception

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

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

Diminished sensitivity because of constant stimulation 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. Frequency

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. Conduction

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. Sensorineural

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

Somatosensation is the technical term for this sense. Touch

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

Pressure, warmth, cold, and pain 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. Sensation

Hyperalgesia is an increased sensitivity to this. Pain

The color we see. Hue

Gustation is the technical name of this sense. Taste

The sharpness of vision Acuity
