Document Summary
Sensation: process from which physical energy from the environment (eg. light waves, pressure waves) is captured by our nervous system. Engineered to capture certain types of information from our environment. Transduction: changing physical energy into electrical signals (neural impulses) that can make their way to the brain. Perception: transferring that energy into information, understand the sensory signals that have been captured. Telling the difference from one object to another. Segmentation is critical because you cannot recognize between one object if you can"t tell the difference with another object in the environment. Gestalt psychologists developed a series of mental shortcuts to understand the difference between one object to another. Similarity: objects that look similar are more likely to be of the same part or group. Closure: making things as simple as possible, square is on top of the circle as opposed to one bizarre shape.
