AP Psychology 10/28/13 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 (6th 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.

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