Chapter 4: States of Consciousness Flashcards
Alpha wave
- Resemble that of someone relaxed, but awake
- Stage 1 of NREM
- Synchronized
- Low frequency, high amplitude
Beta wave
- Brain waves characteristic during wakefulness
- Low frequency, low amplitude
Biological rhythm
Internal cycle of biological activity
Cataplexy
- Lack of muscle tone/muscle weakness,
- Sometimes presents as paralysis
Central sleep apnea
Disruption in signals sent from the brain that regulate breathing cause periods of interrupted breathing
Circadian rhythm
Biological rhythm that occurs approx. 24 hours
Codeine
- Opiate
- Low potency
- Often prescribed for minor pain
Cognitive-behavioral therapy
- Focuses on cognitive processes/problem behaviors
- Used to treat sleep disorders
Collective unconscious
- Theory developed by Carl Jung
- Repository of info believed to be shared by everyone
Consciousness
Awareness of internal & external stimuli
Continuous positive airway pressure (CPAP)
- Device used to treat sleep apnea
- Pumps air into the person’s airways,
forcing it to remain open
Delta wave
- Stage 3 of NREM
- Lowest frequency, highest amplitude
Depressant
- Drug that suppresses the CNS
Euphoric high
Feelings of elation and pleasure from drug use
Evolutionary psychology
Study of how patterns of behavior & cognitive processes evolved over time (due to natural selection)
Hallucinogen
- Results in alterations in sensory and perceptual experiences
- Characterized by hallucinations
Hypnosis
- State of extreme self-focus and attention
- No attention is given to external environment
- Often led by a therapist
Insomnia
- Consistent difficulty in falling/staying asleep
- Must occur 3 nights a week for at least a month
Jet lag
Symptoms resulting from mismatch between internal circadian rhythms and environment
K-complex
- High amplitude pattern of brain activity occurring due to environmental stimuli
- Stage 2 of NREM
Latent content
- Hidden meaning of a dream
- Sigmund Freud
Lucid dream
When people are aware that they’re dreaming and can control the dream’s content
Manifest content
- Storyline of events that occur during a dream
- Sigmund Freud
