Document Summary

Process of receiving, converting and transmitting information. Receptors convert energy of chemical reaction into action potentials. The spatial and temporal pattern of nerve impulses represents the stimulus in a meaningful way. Stimulus becomes more complex as processed further. Searches for elements associated with that knowledge. = relationship between attributes of the physical world and our psychological experiences of them. Level of energy required to activate that sense. The smallest amount of energy that can be detected by a system. Lowest level of stimulation that can be detected 50% of the time. The smallest difference to notice a stimulus change. Can change within a person over time and as a function of hormone status. Ability to taste foods as we get older. Of brain is involved in visual processing. Vast majority of image goes to other side of brain, some stays on the same side. Trails to get to back of brain. Sends as much information needs to go.
