Document Summary
Sensation: the detection of physical energy from objects and encoding it as neural signals. Perception: the process by which we organize and interpret sensations. We can never know the world as it truly exists. Transduction: converting the physical energy from objects into nervous system signals that can be sent to the brain. Not everything we sense is perceived. Selective attention: attention is focused on selected events and others are excluded. Grouping for simplicity: assembling sensory experiences into meaningful wholes makes them easier to understand. The environment appears organized, consistent, and predictable through perceptual processes. Perceptual constancy: perceiving objects as remaining unchanged despite our changing sensations of them. Perceptual processes enable us to judge distance and depth (refer to pg 195) Retinal disparity: the slight difference in lateral separation between 2 objects as seen by the left eye and the right eye. Relative size of objects: the smaller an object"s image on the retina, the farther away the object appears.
