SOLUTIONS 100% CORRECT
◉ What is synesthesia? Answer: is a neurological phenomenon in
which stimulation of one sensory or cognitive pathway leads to
stimulation of another sensory or cognitive pathway
◉ What is perception? Answer: The way the mind organizes,
interprets and identifies sensations in order to form mental
representation
◉ What is transduction? Answer: The way sensory receptors
communicate with the brain in which the body converts physical
signals from the environment and encodes them into neural signals
thay are then sent to the CNS
◉ What is psychophysics? Answer: A method that measures the
strenght of a stimulus and someones sensitivity to that stimulus
◉ What is an absolute threshold? Answer: The minimal intensity
need to just barely detect a stimulis in 50% of the trials
,◉ What is the just noticable difference? Answer: The minimal
chance in stimulus that can just barely be noticed. Not a fixed
quantifty, and is roughly proportional to the intensity of the stimulus
◉ What is webers law? Answer: The just noticable difference of a
stimulus is a constant proportion despite variation in intensity
◉ What is signal detection theory? Answer: The response to a
stimulus depends both on a person sensitivity to the stimulus in the
presence of noise and on a persons decision criterian
◉ What is sensory adaption? Answer: When you adapt to a
condition because your expose was so prolonged
◉ We "see" light waves. What are the three properties of light waves
and what do they determine? Answer: The length of a light wave
determines its hue or what we see ass color, the intensity or
amplitude of a light wave (how high the peaks are) determine what
we see as brightness, and the purity is the number of distinct
wavelengths that make up the light or what we percieve as
saturation
◉ What is the cornea? Answer: A clear smooth outer tissue thay
light first passes through
,◉ What is the pupil? Answer: A hole in the colored part of the eye
which light goes through after the cornea
◉ Whay is the iris? Answer: The colored part of the eye that is
translucent donut shaped muscle that controls the size of the pupil
and hense the amount of light that passes through the eye
◉ What is the retina? Answer: Light sensitive tissue lining the back
of the eyeball that recieves light from the lens
◉ What is accomidation Answer: The process in which the eye
maintains a clear image of the retina. The lens flattens for things
further away and rounds for things closer
◉ What are cones? Answer: Cones detect color, operate under
normal daylight conditions and allow us to focus on fine detail
◉ What are rods? Answer: Rods becoms active under low light
conditions for night vision. Much more sensitive then cones
◉ What is the fovea? Answer: An area in the retina where vision is
the clearest and there are no rods at all, which reduces sharpness in
reduced light
, ◉ How does transduction occur (how does the light wave become a
neiral impulse)? Answer: the bipolar cells collect neural signals from
the rods and cones and transmit them to the retinal ganlion cells
which then organize the signals and send it to the brain through the
optic nerve.
◉ Why do we have a blind spot? Answer: Because there is a lack of
rods and cones where the optic nerves and the blood vessels leave
the eye
◉ There are three types of cones- what color of wavelengths do they
respond to? Answer: Red (long wavelengths) , green (medium
wavelenghts) , or blue (short wavelengths) light
◉ How do we see more than three colors? Answer: Because objects
selectively absorb some wavelenghts of light and reflect others
◉ What is color afterimaging and why does it occur? Answer: When
you stare at a color too long it fatigues the cones that respond and
you will probably see a tint of that color for a while
◉ What are feature detectors? Answer: Neurons that respond to
specific orientations of edges
