Psych109 Sen&Percep

Sensation and Perception

Sensation awareness of properties of an object or event that occurs when a type of receptor (such as those in the back of the eye, in the ear, on the skin) is stimulated.
Perception The act of organizing and interpreting sensory input as signalling a particular object of event.
Perception relies on two phases of processing. What are these? Organization into coherent units and identifying what and where.
Organization into coherent units. We do not see blobs and lines, we see defined objects and surfaces. In order to make sense of the chaos of shapes and colours, we register the size and locations of objects.
Identifying what and where The surfaces and objects that we see are meaningless, and our brains recognize and identify what we see. We also take note of where things are spatially. Car example. (parked versus crossing street)
