Document Summary
There are two stages of detecting and translating the complexity of the world into meaningful experiences. Sensation: the process of detecting external events by sense organs and turning those stimuli into neural signal. Perception: taking the information we have sensed and organizing + interpreting them. Transduction: when specialized receptors transform the physical energy of the outside world into neural impulses gives rise to our internal representation of the world different for different senses. Doctrine of specific nerve energies johannes muller: different parts of the brain sense different stuff, not fully distinct in developing brains. Perception is a skill that is learn through experience. Orienting response how quickly shift our attention to stimuli that signal a change in our sensory world. Absolute thresholds the minimum amount of energy or quantity of a stimulus required for it to be reliable detected at least 50% of the time it is present: different between people and species.
