a clear covering that protects the eye and begins to focus the incoming light.
cornea
a small opening in the center of the eye
pupil
the colored part of the eye that controls the size of the pupil by constricting or dilating in response to light intensity.
iris
a structure that focuses the incoming light on the retina
lens
the layer of tissue at the back of the eye that contains photoreceptor cells.
retina
when the focus is behind the retina we say that the person
near sighted
farsighted
the focus is in front of the retina, we say that the person is
nearsighted
farsighted
Study of effects of physical stimuli on sensory perception and mental states
psychophysics
psychodynamic
evolutionary
structuralism
the inability to detect either green and/or red colors.
color blindness
the inability to detect either green and/or red colors.
Young-Helmholtz trichromatic color theory
roposes that we analyze sensory information not in terms of three colors but rather in three sets of “opponent colors”: red-green, yellow-blue, and white-black.
opponent-process color theory
a meaningfully organized whole.
gestalt
messages from our bodies and the external environment that supply us with information about space and distance.
depth cues
The retina has two types of photoreceptor cells: rods, which detect brightness and respond to black and white, and cones, which respond to red, green, and blue.
true
false
height of the sound wave
amplitude
wavelength of the sound wave
frequency
the perceived frequency of a sound.
pitch
the unit of relative loudness
decibal
the external and visible part of the ear
pinna
tightly stretched, highly sensitive membrane
tympanic membrane (eardrum)
a snail-shaped liquid-filled tube in the inner ear.
cochlea
the membrane covering the opening of the cochlea, to vibrate, disturbing the fluid inside the cochlea.
oval window
the hammer (or malleus), anvil (or incus), and stirrup (or stapes)
ossicles
The frequency theory of hearing suggests that as a sound wave’s pitch changes, nerve impulses of a corresponding frequency enter the auditory nerve.
true
false
a set of liquid-filled areas in the inner ear that monitors the head’s position and movement, maintaining the body’s balance
vestibular system
olfaction
kinesthesia
proprioception
the working together of different senses to create experience
sensory interaction
the ability to focus on some sensory inputs while tuning out others.
selective attention
a decreased sensitivity to a stimulus after prolonged and constant exposure
sensory adaptation
The ability to perceive a stimulus as constant despite changes in sensation
perceptual constancy
the conversion of stimuli detected by receptor cells into electrical impulses that are then transported to the brain—
transduction
Pressure, hot, cold, and pain, but only the sensation of pressure has its own specialized receptors.
true
false
