Document Summary
Perception depends on the properties of your senses. Our ability to take environmental energy and take it into a signal. Our brain taking in the sensory activity and it is activating touch, taste, etc. Seeing a tree is sensation and then going over and deciding to touch it is perception. Transduction: transformation of environmental energy into electrical energy by sensory receptors. The light entered into our body is altered (stretched and transformed so we are able to see the environment) = principle of transformation. Principle of representation = everything a person perceives is based not on direct contact with stimuli but two principles go hand in hand. Sensory receptions - each sense has specific receptors for reception. Once transduction occurs, then it will activate thousands of neurons in the brain - many brain areas that work together. These processes have multidirectional arrows because you will be gaining more information and have more experience with stimuli.
