AP PSYCHOLOGY

Detailed explanation-1: -Alpha waves are seen in the electroencephalogram (EEG) during a normal wakeful state where the subject is quietly resting. Beta EEG are present when a person is alert/attentive and thinking actively. Theta rhythm (Stage 1) of sleep is present during the transition from wakefulness to sleep.

Detailed explanation-2: -Theta Brainwaves: Like Delta brainwaves, theta waves occur when you are relaxing or sleeping, and indicate dreaming and focus.

Detailed explanation-3: -Alpha waves, which measure between 8 and 12 Hz, occur when people feel relaxed and when the brain is in an idle state without concentrating on anything. Beta waves, which measure between 12 and 30 Hz, are the waves that occur during most conscious, waking states.

Detailed explanation-4: -Alpha brainwaves are slower, and higher in amplitude. Their frequency ranges from 9 to 14 cycles per second. A person who has completed a task and sits down to rest is often in an alpha state. A person who takes time out to reflect or meditate is usually in an alpha state.

Detailed explanation-5: -One way alpha brainwaves may negatively affect our mental health is during sleep. Alpha waves are normally only observed during Stage 1 of sleep. Its activity slows down and disappears as sleep progresses past Stage 1 and into Stage 2. However, alpha brainwave activity can sometimes trigger during the Stage 3 of sleep.
