Presentation Transcript
warm up
Warm-up
  • Get video presentations ready.
audition
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
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.
pitch perception
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
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
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
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
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
Body Position
  • In notes: explain the difference between kinesthesis and vestibular sense.
senses broken down
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 (6th sense -> curry?).

  • Smell is made up of what distinct senses?

Smells are individual! About detectable 10,000 odors for humans.

linked senses
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.
