Essentials of Understanding Psychology: States of Consciousness Chapter 4 focuses on the states of consciousness. While some psychologists prefer to exclude studying the topic because of its reliance on "unscientific" introspections of experimental participants, contemporary psychologists support the view that several approaches permit the scientific study of consciousness. We can study brain wave patterns under conditions of consciousness ranging from sleep to waking to hypnotic trances. Also, understanding the chemistry of drugs such as marijuana and alcohol has provided insights into the way they provide pleasurable --as well as adverse-- effects. Another reason for the study of consciousness is the realization that people in many different cultures routinely seek ways to alter their states of consciousness. Consciousness may alter thinking. It may alter people's sense of time and perceptions about oneself or the world. This chapter considers several states of consciousness, such as sleeping and dreaming, the states of hypnosis and meditation and finally drug-induced states of consciousness.
