Auditory Process: Perceiving Pitch

Place Theory: Links the pitch we hear with the place that is stimulated in the cochlea

Frequency Theory: Measures neural impulses travelling the auditory nerve.

Auditory Localization The brain calculates a sound’s

location by using these differences. Timing (.000027sec. Diff) Sound travels @ 750 mph

Sound Waves Loudness (amplitude) Pitch (frequency)

Long waves; low frequency/low pitch

Short waves; high frequency/high pitch

Taste Buds Photograph of tongue

surface (top), magnified 75 times.

10,000 taste buds line the tongue and mouth. Taste receptors are

down inside the “bud”

Children have more taste buds than adults.

Sensory Integration Different sensory modalities exist because

signals received by the sense organs stimulate different nerve pathways leading to different areas of the brain.

Synesthesia A condition in which stimulation of one sense

also evokes another.

Starburst time!! Conduct the experiment and answer the

following questions with your partner. What factors influence taste? What are the 5 basic tastes? What is sensory interaction? How do we experience smell? Use pages 146-150 to help answer the

questions.

Different Tastes Different people have different tastes based

on: Genetics Culture Learning Food attractiveness

Smell: The Sense of Scents

Airborne chemical molecules enter the nose and circulate through the nasal cavity. Vapors can also enter through the mouth and pass into

nasal cavity. Receptors on the roof of the nasal cavity detect these

molecules.
