Function
When an individual encounters a novel environmental stimulus, such as a bright flash of light or a sudden loud noise, he or she will pay attention to it even before identifying it. This orienting reflex seems to be present early in development, as babies will turn their head toward an environmental change. From an evolutionary perspective, this mechanism is useful in reacting quickly to events that call for immediate action.

Famous quotes containing the word function:
“We are thus able to distinguish thinking as the function which is to a large extent linguistic.”
—Benjamin Lee Whorf (1897–1934)
“Science has fulfilled her function when she has ascertained and enunciated truth.”
—Thomas Henry Huxley (1825–95)
“Uses are always much broader than functions, and usually far less contentious. The word function carries overtones of purpose and propriety, of concern with why something was developed rather than with how it has actually been found useful. The function of automobiles is to transport people and objects, but they are used for a variety of other purposes—as homes, offices, bedrooms, henhouses, jetties, breakwaters, even offensive weapons.”
—Frank Smith (b. 1928)
