[2] Biological Basis of Behavior [Hearing Perception] Flashcards
(11 cards)
Wavelength
The distance between two consecutive peaks or troughs in a wave, which affects the perception of pitch.
Pitch
The perceptual quality of sound that allows us to classify it as “high” or “low.”
Amplitude
The height of a sound wave, which determines the loudness of a sound.
Loudness
The perceptual quality of sound that corresponds to its amplitude or intensity.
Pitch perception
The ability to interpret the frequency of sound waves as distinct pitches.
Place theory
The theory that different frequencies of sound stimulate different parts of the cochlea, which determines the pitch we perceive.
Volley theory
A theory suggesting that groups of neurons fire in volleys to detect sounds with frequencies higher than what a single neuron can detect.
Frequency theory
The theory that the frequency of sound waves corresponds to the rate at which neurons fire, allowing us to perceive pitch.
Sound localization
The ability to determine the location of a sound source based on the sound’s intensity and timing.
Conduction deafness
Hearing loss caused by problems with the mechanical system that transmits sound to the inner ear.
Sensorineural deafness
Hearing loss caused by damage to the cochlea or auditory nerve.
