Controlled processing; the voluntary use of a attention & conscious effort. Automatic processing; performed with little or no conscious effort stages of sleep. Stage 1; transition period b/w wakefulness & sleep = light stage, brain produces high amplitude of theta waves = slow brain waves, last 5-10 min, sudden body jerk feeling. Stage 2; about 20min, brain produces bursts of rapid rhythmic brain waves activity known as sleep spindles = you are asleep, muscles are more relaxed your breathing & heart rate are lower & are harder to awaken.
