Warm-up Get video presentations ready.

Audition Amplitude: strength of sound waves = loudness (amp) Frequency: wavelength of sound waves = pitch (high-frequency pitch) Timbre: used to distinguish sounds of same amplitude & frequency.

The Ear! Draw & label the ear. Outer ear, middle ear, & inner ear. Pinna (visible part of ear), auditory canal, eardrum (tympanic membrane), hammer, anvil, stirrup, oval window, cochlea, basilar membrane, auditory nerve.

The Ear!

Pitch perception How do place theory and frequency theory combine to explain pitch? What is the volley principle, and how does it explain why frequency theory is limited to lower pitches? Place: the place in the cochlea that vibrates the most determines pitch (most accurate with high pitches) Frequency: the number of neural impulses match the frequency of a tone, which determines pitch (most accurate with low pitches)

Hearing tidbits… Why is it important to have two ears? What is the difference between conduction hearing loss and sensorineural hearing loss? Which is more common? What is a cochlear implant? Why is it controversial?

Touch Why does growth & metabolism slow at a young age when deprived of touch? What are phantom limb sensations? What do they reveal about pain? What is the gate-control theory of pain? How can you mitigate pain according to this theory? Write a paragraph explaining what your “pain tolerance” is, and how it was formed by biology, culture, and psychology (see: page 226).

Taste What is the evolutionary argument for children disliking new meats and vegetables? What is the biological argument for children disliking new meats and vegetables?

Smell In what ways is smell unique as a sense? (does not run through the thalamus and it cannot be separated into distinct groups) What does the olfactory system’s location have to do with its ability to produce nostalgia? How are the olfactory and gustatory systems linked?

Body Position In notes: explain the difference between kinesthesis and vestibular sense.

Senses broken down… Sight is made up of what three distinct senses? Red, blue, and green. Hearing is made up of what three distinct senses? Volume, pitch, and timbre. Touch is made up of what four distinct senses? Pressure, warmth, cold, and pain. Taste is made up of what five distinct senses? Salty, sweet, sour, bitter, & umami (6 th sense -> curry?). Smell is made up of what distinct senses? Smells are individual! About detectable 10,000 odors for humans.

Linked senses What is sensory compensation? Give an example. What is sensory interaction? What does it reveal about the evolution of our senses? Synaesthesia: one sensation produces another. McGurk Effect:

Senses chapter Overall, what perspective of psychology would you say this chapter was written from? Why?

Homework… Review for the test Wednesday! It is cumulative for the quarter! Chapters 1-5.
