Document Summary

More related to extracting meaning from what you sense, tying it to what you know and understand: explain the processes by which physical energy is interpreted by the brain. Each receptor varies its responses to stimuli that differ quantitatively and qualitatively: quantitative changes > changes in the magnitude of a stimulus. Intensity of sound or light you perceive these as changes in loudness or brightness: qualitative changes > changes in type of stimulus energy. Changes in frequency of sound/ wavelengths of light perceived as different pitches/ different colours. Vision: sensing light and its re ection off surfaces with the eyes, includes perception of objects in three dimensions at variety of distances with a multitude of colours and textures. Hearing: sensing vibrations in air with the ears. The chemical senses: taste (gustation) and smell (olfaction: work through chemical compounds binding to specialized receptors in the body, work in similar ways and work together in perception.
