Document Summary
Unit 4: sensation and perception (hardware to software) What is necessary for you to experience the dancing elephant" illusion: a brain, sight, knowledge of what an elephant may look like. Why do things appear as they do: example. Contrast we overcompensate (moon looks brighter at night: experience. Properties of sensory organs we use: sensory organs evolved limits. See a typical range because of evolved limits (cannot see infared) Light light waves: light travels in a straight line. Colour and wavelength: something that we construct our interpretation of colour based on those wavelengths (personally constructed interpretation) Visual fields (basically pathways cross so even when your eyes are closed, you still see both sides) Pathway 1: form, colour, brightness, contrast, depth. Pathway 2: localization in space, coordination with other sensory input. Phenomenally blind (damaged pathwat 1) their primitive pathway(pathway 2) is still functioning (can navigate a room that they have never been before without tripping.
