Document Summary

Everything we learn is detected by sense organs and transmitted to our brains by sensory nerves. Sense organs and sensory nerves provide us with useful information about the outside world. Ex. there is a clear difference between vision and audition. Vision: we see different things every second, but we have a sense that our visual world is stable the visual system must provide that stability. So our senses are attuned to different aspects of our world, and they combine together to give us a rich experience of the world. Audition is important for social behavior, vision for information about distant events, sense of smell can tell us about sources of aromatic molecules far upwind. Taste and touch deal with events occurring immediately nearby. Experience is traditionally studied by distinguishing between sensation and perception. Sensation: the detection of the elementary properties of a stimulus ex. seeing the colour red, seeing a movement.
