Little effect on behavior: only small effect on attitudes. Channeled soundwaves pressures eardrum, activates middle ear, amplifies sound and puts pressure on oval window. Inner ear: cochlea, middle of it has fluid filled membrane, with hair like cells on membrane, movement of hairs causes action potentials sending nerve impulses to brain: vestibular system: Important for bodily orientation or equilibrium (vertical, horizontal, diagonal: semicircular canal and vestibular sacs connected to cochlea, filled with fluid lined with hair cells sensitive to movement, sensitive to acceleration/deceleration, perception of loudness, coding occurs in 2 ways. Our visual system reacts to the reflected light waves: our perceptual capabilities are impacted by the limits of our nervous system, anatomy: Lens: located behind pupil can become thinner to focus on far objects, thinner to focus on near objects (accommodation).
