Document Summary
Processing of info from the body/environment and its transformation into meaning/representations that can be used for reasoning and action. Convert into electrical signals that the brain uses to create meaning for us. Transducers do this^ (ex: retina takes in info from the environment, light waves) Motion and body position proprioception (not always viewed as a separate sense) *proprioceptive sense = sense of where your different limbs are and how they"re moving. Embedded in retina = millions of light-sensitive cells. A lot more sensitive than cones (100x more) Some people have 4 different types of cones and can see way more colours^ Cats only have 2 types of cones. Mantis shrimp has 16 cones, can see a huge array of colours. *fewer cone cells for peripheral vision (we don"t see much colour at all in peripherals) No colour and little detail in periphery. Size: we know how big things are.
