midterm 2

the act of converting sensation into neural impulses

the smallest amount of stimulus one can detect

the minimal difference needed to notice a difference between two stimuli

this type of threshold is propotional to the stregth of the original stimulus

this type of adaptation allows us to focus on important stimuli

when a babies cry can wake a mother up, but a thunderstorm can not...this is an example of?

this type of processing intakes raw sensory data to the brain, the brain uses all the data to build a perception

when you expect to see a specific object, you are more likely to interpret it that way

light waves enter the ______

light enters the eye through a small opening called a

light is focused by the _____

in the eye the _____ contains all the receptor cells and transduces light into nerve impusles

these sensory receptors are abundant in the eye and are sensitive to light, but not acute

these eye receptors are used for central and color vision

these eye receptors need more light than their counter part

the regio of our vision where vision is the sharpest

this part of the eye is made up of cones, in the center of the retinA

3 characteristics of light

visual information leaves the retina and enters the part of the brain called the ______ initially, and then the primary visual cortex in the _____ lobe

this pathway in the visual process is object identification and facial recognition

this pathway in the visual process identifies where an object is in space

This condition occurs when there is damage to the temporal lobe; cennot recognize objects

one form of visual agnosia;the patient cannot recognize faces
