sensations to self (poverty of stimulus). This is information based. Perception in action – without perception, action would be unguided, and without action, perception would serve no purpose. Unconscious interference – human vision is incomplete and that details are inferred by the unconscious mind to create a complete picture. Eyes create 2D, but the mind adds the 3 rd dimension with motion. Information processing – the mind is like a computer, information is made available by the environment is processed by a series of processing systems, transfer or alter the info in systematic ways, aim of research was to specify the processes Synesthesia – perceptual phenomenon in which one sensory path has an automatic second pathway. IE letters as colors, words as tastes. Countershading – an evolutionary action by animals in which their tops are colored in a way to the lower half looks invisible. A dik-dik has a brown top, but a white bottom so the white can shine and make it look skinnier. Different sources of depth Texture gradients, light and shade, size, aerial perspective, interposition, the kinetic depth effect, accommodation Motion parallax – things further away move slower than those who are closer to us. Shading – caves and mountains. We automatically assume only one light source. Feature detectors – neurons in the brain which code for perceptually significant stimuli > seeing edges, shape angles, or movement. Extrastriate Visual areas – area next to the primary visual cortex, contains V3, V4, V5/MT, which is sensitive to motion or perception of human bodies and faces, also matching colors and auditory association Binocular Vision – both eyes aim simultaneously at the same visual target, like a coordinated team. Stereopsis – two separate images from two eyes are successfully combined into one image in the brain, which creates depth perception Stereoscopic vision – being able to view with both eyes similar, but slightly different Blindsight – the ability to respond to visual stimuli without consciously perceiving them. The Zombie in the Brain – being able to sense nerve impulses, able to distinguish shapes and colors, but also depth of an object Motion Perception – Living things move, Motion Parallax/Optic Flow, Defeating Camouflage, recognizing biological motion

Retinal ganglion cells are what connect the light waves into the optic nerve. They are what perceive the movement. Apparent motion – when static images are believed to move Real motion – change of position relative to other objects in a visual field Induced motion – when a stationary or moving object appears to move because of the other objects around them Autokinetic Effect – a small point of light will appear to move in a dark room, even though it is stationary. It is because the eye muscles become fatigued and the light begins to bounce. Saccadic suppression – (SSID) – where there is no visual processing during eye movements. IE: moving your eye left to right, or blinking. It’s just forgotten and not detected.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
