Document Summary
The processing of information from the body or environment and its transformation into meaningful representations that can be used in the service of reasoning and action. Understanding perception as a process of converting energy that"s coming to the various sensory organs into electrical signals that the brain can then use to create representation that have meaning for us. Typical sensory modalities divided into different modalities (what is the relevant sense organ?) Proprioception is your sense of where your different limbs are at any given moment and how it is that their moving (touch) Visual perception is the process of converting light information into information that can be used by a perceiver. Rods: the most light sensitive photoreceptive cells in the retina: good for monochrome vision in low light (night vision) Cones (3 types) fewer cones than rods cones allows us to see colour: correspond to short length (blue), medium length (green) and long wavelengths (red)
