Modules 18 and 19 Flashcards
Act or sense of hearing
Audition
Determines loudness
Amplitude
Measured in hertz and determines pitch
Frequency
A tone’s experienced highness or lowness, depends on frequency
Pitch
Measured in decibels
Sound Intensity
Chamber between eardrum and cochlea constraining 3 tiny bones that concentrate vibrations of the eardrum on the cochlea’s oval window
Middle ear
Coiled, bony, fluid-filled tube in the inner ear; sound waves traveling through the cochlear fluid trigger nerve impulses
Cochlea
Innermost part of ear, containing the cochlea, semicircular canals, and vestibular sacs
Inner ear
Main mechanical element within cochlea of inner ear
Basilar Membrane
Primary sensory receptor cells within the inner ear
Hair Cells
Relays neural activity to CNS
Auditory Nerve
Part of temporal love that processes auditory information
Auditory Cortex
Nociceptors
Sensory receptors
The most common form of hearing loss, caused by damage to cochlea’s receptor cells or auditory information
Sensorineural hearing loss (nerve deafness)
Caused by damage to the mechanical system that conducts sounds waves to the cochlea
Conduction hearing loss
Device that converts sounds into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea
Cochlear implant
Links the pitch we hear with the place where the cochlea’s membrane is stimulated
Place Theory (place coding)
The rate of nerve impulses traveling up the auditory nerve matched the frequency of a tone, thus enabling us to sense its pitch
Frequency Theory (temporal coding)
The spinal cord contains a neurological “gate” that blocks pain signals or allows them to pass on to the brain
Gate-control Theory
Pain signals traveling up small nerve fibers (open or close)
Gate Opens
Large fibers or information coming from the brain (open or close)
Gate Closes
Phantom sound of ringing ears
Tinnitus
People are likely to do whatever they see as being the norm
Social Influence Theory
When an auditory component of one sound is paired with a visual component, leading to the perception of a third sound
McGurk Effect
Idea that many features of cognition are shaped by the state and capacities of an organism
Embodied Cognition
Where a person suggests to another that certain perceptions, feelings, thoughts, or behavior will spontaneously occur
Hypnosis
Split in consciousness, allows some thoughts and behaviors to occur simultaneously with others
Dissociation
