2 Localization of Sounds Because we have two ears, sounds that reach one ear faster than the other ear cause us to localize the sound.

3 Localization of Sound 1. Intensity differences 2. Time differences Time differences as small as 1/100,000 of a second can cause us to localize sound. The head acts as a “shadow” or partial sound barrier. Sound Localization Demonstration – Myers Resources

4 Touch The sense of touch is a mix of four distinct skin senses—pressure, warmth, cold, and pain. Bruce Ayers/ Stone/ Getty Images

5 Pain Pain tells the body that something has gone wrong. Usually pain results from damage to the skin and other tissues. A rare disease exists in which the afflicted person feels no pain. Ashley Blocker (right) feels neither pain nor extreme hot or cold. AP Photo/ Stephen Morton

6 Gate-Control Theory Melzack and Wall (1965, 1983) proposed that our spinal cord contains neurological “gates” that either block pain or allow it to be sensed. Gary Comer/ PhototakeUSA.com

7 Pain Control Pain can be controlled by a number of therapies including, drugs, surgery, acupuncture, exercise, hypnosis, and even thought distraction. Rubbing an area that is sore can sometimes decrease the pain, because it overloads the sensory neurons in the area.

8 Smell Like taste, smell is a chemical sense. Odorants enter the nasal cavity to stimulate 5 million receptors to sense smell. Unlike taste, there are many different forms of smell.

9 Smell and Memories The brain region for smell (in red) is closely connected with the brain regions involved with memory (limbic system). That is why strong memories are made through the sense of smell.

10 Sensory Interaction When one sense affects another sense, sensory interaction takes place. So, the taste of strawberry interacts with its smell and its texture on the tongue to produce flavor.

11 Taste Traditionally, taste sensations consisted of sweet, salty, sour, and bitter tastes. Recently, receptors for a fifth taste have been discovered called “Umami”. Sweet Sour Salty BitterUmami (Fresh Chicken) Jelly Bean Activity - Meyers

12 Body Position and Movement The sense of our body parts’ position and movement is called kinesthesis. The vestibular sense monitors the head’s position. http://www.heyokamagazine.com Whirling Dervishes Wire Walk Bob Daemmrich/ The Image Works Vestibular Sense Demonstration - Meyers
