AP PSYCHOLOGY

Detailed explanation-1: -Sleep is a unique state of consciousness; it lacks full awareness but the brain is still active. People generally follow a “biological clock” that impacts when they naturally become drowsy, when they fall asleep, and the time they naturally awaken.

Detailed explanation-2: -There are also many common experiences that create altered states of consciousness (ASC), such as sleeping or daydreaming, sleep deprivation, euphoria or panic. Dream state, hypnosis, and meditation are also considered as ASC. ASC is a relative state of mental functioning.

Detailed explanation-3: -An altered state of consciousness is defined as a state in which the neurocognitive background mechanisms of consciousness have an increased tendency to produce misrepresentations such as hallucinations, delusions, and memory distortions.

Detailed explanation-4: -However, there are also wakeful situations in which we can experience an altered state of consciousness (ASC)-these include hallucination, hypnotic states, trance states and meditation.

Detailed explanation-5: -Sigmund Freud divided human consciousness into three levels of awareness: the conscious, preconscious, and unconscious. Each of these levels corresponds to and overlaps with Freud’s ideas of the id, ego, and superego.
