Study Notes
Levels of Consciousness
- Conscious Level: We are aware of our surroundings and our awareness.
- Preconscious Level: Information not currently in awareness but can be accessed easily (e.g., what you wore yesterday).
- Unconscious Level: Information hidden from conscious awareness (according to Freud), such as selfish needs or fears.
- Nonconscious Level: Basic biological functions beyond our conscious control (e.g., hair growth, pupil dilation).
Altered States of Consciousness
- A change in our sense of self or the world around us.
- Sleep is an example of an altered state of consciousness.
- Other altered states can occur through meditation, biofeedback, and hypnosis.
Freud's Levels of Consciousness
- Freud compared consciousness to an iceberg, with the majority of our thoughts and feelings residing below the surface in the unconscious.
Stages of Sleep
- Sleep is characterized by distinct brain-wave patterns measured by an electroencephalograph (EEG).
- Stage 1: Lightest sleep, characterized by theta waves and potentially vivid images. Easily awakened.
- Stages 2, 3, and 4: Deep sleep with progressively slower brain waves (delta waves). Most difficult to awaken in Stage 4.
- REM (Rapid Eye Movement) Sleep: Characterized by irregular breathing, increased heart rate, and brain waves similar to Stage 1. Eye movement under closed eyelids.
- Typical sleep cycle involves approximately five cycles of NREM (non-REM) and REM stages, with REM sleep periods increasing as the night progresses.
