Sensation
The process of detecting environmental stimuli and converting them into signals that can be detected by the nervous system
Sensation
The lowest strength of a stimulus that a person can detect 50% of the time.
Absolute threshold
The spiral cavity of the inner ear which produces nerve impulses in response to sound vibrations.
Cochlea
Photoreceptor cell responsible for color vision.
Cone
The conscious focus on one stimulus among many
Selective attention
The convergence of energy into a different form (much like light energy for vision).
Transduction
Describes a tendency to perceive some sensory stimuli and to ignore others.
Perceptual set
Found inside the inner ear. It is made up of three fluid filled semicircular canals that help you maintain your balance
Vestibular system
The transparent part of the eye that covers the iris and the pupil and allows light to enter the inside.
Cornea
Not noticing stimuli when focused on others
Inattentional blindness
Theory that suggests that the way humans perceive colors is controlled by three opposing systems.
Opponent process theory
Perceiving the world around us by drawing from what we already know in order to interpret new information
Top down processing
Name the 3 parts of the inner ear.
hammer, anvil, and stirrup
Photorecptor cell responsible for vision at low light levels and seeing black white and grey.
Rods
Failing to notice changes in the environment, especially
when selective attention focuses our conscious thought on a single stimuli
Change blindness
Diminished sensitivity to a stimulus that occurs due to constant exposure to that stimulus.
Sensory adaptation
The impact of stimuli on our cognition
and judgement that is too quick or weak to consciously interpret or process
Subliminal messaging
Type of hearing loss due to damage to the cochlear
receptor hairs/cells or auditory nerves.
Sensorineural hearing loss
Seeing swirls of color when you hear music because stimulation of one sensory pathway leads to the experience of another sensation.
Synesthesia
Diminished sensitivity as a consequence
of constant stimulation.
Sensory adaptation
Theory that our cones and
brain see colors in combinations of mixing red/green/blue receptors
Trichromatic theory
The idea that we begin to perceive items with sensation, as opposed to our conceptual ideas.
Bottom up processing
The membrane that separates the outer and middle parts of the ear and vibrates when sound waves strike it.
Eardrum
Which of the following is the correct order of the eye-to-brain pathway of vision?
Retina, optic nerve, thalamus, occipital lobe
Your talking with your friends at a cafeteria table when suddenly your distracted by hearing your name at another table. Your shift of attention demonstrates which psychological concept?
Cocktail party phenomenon
