Processing the Environment

P/S

Visual cues

Depth, Form, Motion, Constancy

depth

how far or close an object is

motion

our ability to sense and interpret movement, encompassing both the movement of objects around us and our own body's movement

form

visually perceive objects in the world in response to the patterns of light that they caste on our retinas

Binocular Cues

retinal disparity

convergence

convergence

looking far way→ eyes are relaxed

looking closer to us → eyes contract

monocular cues

relative size

interposition

relative height

shading and contour

motion parallax

relative size

one object percieved to be bigger → think of it being closer to us

interposition

object in front is closer to us

relative height

higher object → further away

shading and contour

using light and shadow to interpret form

constancy

our perception of object doesn’t change even if it looks different on retina

size, shape, color

sensory adaptation

change in the sensitivity of your perception of a sensation

hearing

adapt to loud noises → inner ear muscles contract to protect ear drum

touch

sensory nerves saturated → temperature receptors densensitized

smell

can detect chemicals in air

over time desensitized to molecules

proprioception

sense that tells your brain where your body parts are in space and how they are moving, without needing to look
