Sensation and Perception Flashcards
sensation
process where sensory receptors & nervous systems receive & represent stimulus energies from environment
perception

audition
amplitude determines what? (hearing)
frequency determines what? (hearing)
what is sound measured in?
eardrum
3 bones in the middle ear
cochlea
summary of hearing: vibrations cause the cochlea’s membrane to shake. this causes ripples in the ___ bending the ___ lining its surface. Hair cells convert the messages into neurons that are sent by the __ to the thalamus, then onto the ___ cortex in the ___ lobe.
sensorineural hearing loss
conduction hearing loss
cochlear implant
how do we interpret loudness of a sound
place theory
frequency theory
volley principle
