1) The Pepsi Cool Can In 1990, Pepsi actually withdrew one of its “Cool Can” designs after someone protested that Pepsi was subliminally manipulating people by designing the cans such that when six-packs were stacked at grocery stores, the word SEX would emerge from the seemingly random design. Critics alleged that the red and blue lines on the “Cool Can” design were far from random <27>.

Sound

• Sound - A wave which is created by vibrating objects and transmitted through a medium from one location to another.

• Auditory – having to do with hearing

Compression and Expansion

Pitch

• Frequency – number of cycles per second as expressed in the unit Hertz.

• Hertz – A unit expressing the frequency of sound waves. One Hertz, or 1Hz, equals one cycle per second.

Pitch

• The greater the number of cycles per second, the higher the pitch.

• The greater the number of cycles per second, the higher the pitch.

Loudness

• Amplitude – height• The higher the

amplitude of a wave, the louder the sound.

• Decibel – A unit expressing the loudness of a sound. Abbreviated dB.

Highest Frequency? Loudest? Highest Amplitude? Highest Pitch?

CONDUCTION DEAFNESS

STIMULATION DEAFNESS

ARTICLE: Loss of Hearing Can Be Frustrating!

February 14, 2001

Or

ARTICLE: The Sounds Around UsJanuary 18, 2006

Conduction Deafness

• Caused by the failure of the three tiny bones inside the middle ear to pass along sound waves to the inner ear or the failure of the eardrum to vibrate in response to sound waves

• Possible cause is a build-up of fluid

• Hearing aids • Normal hearing may

return.

Sensory-Neural Deafness

• Damage to the inner ear. Most often caused by loss of hair cells that will not regenerate.

• Damage to the auditory nerve.

• Cochlear implants can help patients with this form of deafness.

Stimulation Deafness

• Exposure to very loud sounds

• Prolonged exposure to 85 dB can cause stimulation loss.

• Ringing sound can mean hair cells have been damaged

Locating Sounds

• A demonstration – three volunteers are needed

The nose knows! Maybe without you

knowing!

Sensations are created by chemical reactions on your taste buds

Taste is heavily influenced by smell – this is called sensory interaction

TASTE QUALITIES

(Get on the Busss!)

• Bitter

• Umami

• Sour

• Salty

• Sweet

FLAVOR DEPENDS ON…• Temperature

• Odor

• Texture

• Taste(I T.O.T.T. you about flavor)

http://www.npr.org/templates/story/story.php?storyId=1813416Study: Tastes Form in Infancy


Touch and Pressure

• Sensory receptors located around the roots of hair cells fire when surface of skin is touched.

• There are at least 6 basic types of touch receptors in your skin.

• One for hot, cold, pain, pressure, touch, and fine touch.

SKIN SENSES*Vision is usually the most dominant of the senses*

• Touch

• Pressure

• Warmth

• Cold

• Pain

TOUCH & PRESSURE

Most sensitive – fingertips, lips, noses and cheeks (page 91)

1. nerve endings are more densely packed in the fingertips and face than in other locations

2. a greater amount of sensory cortex is devoted to the perception of sensations in the fingertips and face

Two-Point Threshold – to assess sensitivity to pressure –The least distance by which two rods touching the skin must be separated before the subject will report that there are two rods, not one, on 50% of occasions

TEMPERATURE

Warm & Cold receptors – they adapt and sometimes they fire simultaneously

PAIN

* The more pain receptors located in a particular area of our skin, the more sensitive that area is. (figure 4.9 on page 91)

*Originates at the point of contact* - message is sent from the point of contact to the spinal cord to the thalamus in the brain. Then it is projected to the cerebral cortex where the person registers the location and severity of the pain.

*Release of various chemicals – prostaglandins, bradykinin, P*

* Aspirin & Ibuprofen work by curbing production of prostaglandins



GATE THEORY – pain messengers can’t get through

ENDORPHINS – Bodies natural pain killers

Endorphins are inhibitory neurotransmitters. They lock into receptor sites for chemicals that transmit pain messages to the brain. Once the endorphin “key” is in the “lock,” pain-causing chemicals cannot transmit their messages. There are a number of endorphins.

Endorphins also play a role in regulating respiration, hunger memory, sexual behavior, blood pressure, mood, and body temperature.

ACUPUNCTURE – ancient procedures/releasing endorphins

PLACEBO – bogus treatment

KINESTHESIS – The sense that informs us about the positions and motion of parts of our bodies

VESTIBULAR SENSE – The sense of equilibrium that informs us about our bodies’ positions relative to gravity
