Document Summary
Sensation-physiological process that underlies transformation of the chemical, mechanical, light, and sound energy in the world into electrical activity in the brain. Perception- psychological process involved in selection, organization, and interpretation of sensations. Transduction-conversion of physical energy into electrical potentials- occurs in sensory receptor cells, which are specialised neurons. Senses act as a gate to the world and is essential for survival. Our senses give us just enough information so that we can behave appropriately. Senses respond to a restricted range of energies in the world. People are more sensitive to change than to constant stimulation, adaption. Our brain has no direct access to physical objects. Sensing requires action- it"s not a passive process. We cannot sense magnetic fields, but some animals can because of evolution. Each receptor varies its responses to stimuli that differ quantitatively and qualitatively. Quantitative- amounts or quantities that can be measured objectively. Qualitative- pertaining to some quality or characteristic other than magnitude.
