Famous quotes containing the words called and/or optimal:
“We went to Mannheim and attended a shivaree—otherwise an opera—the one called “Lohengrin.” The banging and slamming and booming and crashing were something beyond belief. The racking and pitiless pain of it remains stored up in my memory alongside the memory of the time that I had my teeth fixed.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“In the most desirable conditions, the child learns to manage anxiety by being exposed to just the right amounts of it, not much more and not much less. This optimal amount of anxiety varies with the child’s age and temperament. It may also vary with cultural values.... There is no mathematical formula for calculating exact amounts of optimal anxiety. This is why child rearing is an art and not a science.”
—Alicia F. Lieberman (20th century)
