What is sensation? - Answer-Simple stimulation of a sense organ
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
