AP PSYCHOLOGY

Detailed explanation-1: -5 Delta Waves. Delta waves are the slowest recorded brain waves in human beings. They are found most often in infants and young children, and are associated with the deepest levels of relaxation and restorative, healing sleep.

Detailed explanation-2: -Sleeping and Dreaming 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-3: -Theta Brainwaves: Like Delta brainwaves, theta waves occur when you are relaxing or sleeping, and indicate dreaming and focus.

Detailed explanation-4: -Types of Brain Waves Theta waves, which are between 4 and 8 Hz, occur during light sleep or deep relaxation. 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.

Detailed explanation-5: -Theta activity has a frequency of 3.5 to 7.5 Hz and is classed as “slow” activity. It is seen in connection with creativity, intuition, daydreaming, and fantasizing and is a repository for memories, emotions, sensations. Theta waves are strong during internal focus, meditation, prayer, and spiritual awareness.
