| Pitch and loudness are | Psychological (perceptions) |
| Frequency and intensity are | Physical (sensations) |
| Pitch corresponds to | Frequency (hertz) |
| Loudness corresponds to | Intensity (decibels) |
| What are the two theories on sound encoding? | 1) Place theory 2) Frequency theory |
| Place Theory | Different parts of the basilar membrane are stimulated for different frequencies |
| Frequency Theory | Cells fire in proportion to the frequency of a sound |
| What are the three causes of deafness? | 1) Conduction 2) Nerve 3) Stimulation |
| Deafness by Conduction | Caused by damage to the eardrum or bones |
| Deafness by Nerve Damage | Loss of sensors (hair cells or damage to the auditory nerve) |
| Deafness by Stimulation | Overuse or overexposure to loud noise can damage hair cells (ringing in ears after a concert) |
| Doppler Effect | An increase (or decrease) in the frequency of sound as the source and observer move toward (or away from) each other |
| Chemical Sensing | Certain molecules (keys) will be received by certain receptors (locks) |
| Smell is the only sense to bypass the | Thalamus |
| Where are smell receptors located? | Olfactory bulb |
| What do the touch receptors pick up? And where are touch sensors receptors? | 1) Pressure, pain, temperature 2) The skin |
| What does vestibular sense control? And where are the receptors located? | 1) Balance 2) Semicircular canal |
| What does kinesthetic sense control? And where are the receptors located? | 1) Body position 2) Muscles and tendons |
