Document Summary
42-51 & chapter 3: the physiological basis of vision. Chapter 8: the perception of movement and colour. Chapter 6: the perception of direction, distance and depth. Distal (far away) stimulus (constant): an object or event in the envt (any object out in the world) > sensory neurons always collecting info to send to distal, but distal depends on proximal (but proximal"s always changing) Proximal stimulus (: info about a distal stimulus that reaches the receptors, such as a visual image on the retina. (the retinal image of any object out in the world (retinal=upside down)). Motion constancy ex. teacher writes on board, and starts moving around. Distal: what is written on board (stationary/stable image) proximal: teacher moving. Holding a white piece of paper, if in dim lighting, paper comes across as dim as well. However, if standing in bright sunlight, paper comes across as very bright. Distal stimulus stays the same but proximal stimulus changes drastically.
