Document Summary
Sensation: the process of detecting external events by sense organs and turning those stimuli into neural signals. Perception: attending to, organizing and interpreting stimuli that we sense. Transduction: specialized receptors transform the physical energy of the outside world into neural impulses: neural impulses travel into brain and influence the activity of brain structures gives rise to our internal representation of the world. Doctrine of specific nerve energies: proposed by johannes muller, idea that the different senses are separated in the brain. Orientating response describes how quickly we shift our attention to stimuli that signal a change in our sensory world. Sensory adaptation: the reduction of activity in sensory receptors with repeated exposure to a stimulus: allows us to shift our focus to something more important. Stimulus threshold: william gustav fechner coined the term psychophysics: the field of study that explores how physical energy such as light and sound and their intensity relate to psychological experience.
