States Of Consciousness Flashcards
Preconscious
Level of consciousness that is outside our awareness but contains feelings and memories that can easily be brought to conscious awareness.
Unconscious
(subconscious). Level of consciousness that includes often unacceptable feelings, wishes, and thoughts not directly available to conscious awareness.
Nonconscious
The level of consciousness devoted to processes complete,y inaccessible to conscious awareness.
Dual Processing
Processing info on conscious and unconscious levels at the same time.
Hypothalamus
Controls you circadian rhythm, regulating changes in blood pressure, body temp, pulse, blood sugar levels, hormone levels, activity levels, sleep, and wakefulness.
Reticular Formation
Neural network in brainstem (medulla and pons) and midbrain essential to the regulation of sleep, wakefulness, arousal, and attention.
Stage 1
Quick sleep stage with gradual loss of responsiveness to outside, drifting thoughts/images. Theta waves.
Stage 2
About 50% of sleep time. Sleep spindles and k-complexes.
Stage 3
Deep sleep stage. High amplitude/low frequency delta waves.
Stage 4
Deepest stage. Mostly delta waves. Slowed ❤️ rate and respiration, lowered temp and blood flow to the brain. HGH is secreted.
REM
About 80% of dreaming, 5-6 times a night. AKA paradoxical sleep.
NREM
Non REM. Sleep stages 1-4 w/out rapid eye movements.
Manifest Content
The remembered story line of a dream.
Latent Content
The underlying meaning of a dream.
Activation Synthesis Theory
During REM sleep the brainstem stimulates the forebrain with random neural activity, which we interpret as a dream.
Cognitive Information Processing Theory
Dreams are the interplay of brain waves and psychological functioning of interpretive parts of the mind.
Hypnosis
State with deep relaxation and heightened suggestibility. The hidden observer provides evidence for dissociation of consciousness.
Meditation
Set of techniques used to focus concentration away from thoughts and feelings in order to create calmness, tranquility, and inner peace.
Psychoactive Drugs
A chemical that can pass through the blood brain barrier to alter perception, thinking, behavior, and mood.
Depressants
Reduce activity of CNS and induce sleep.
Narcotics
Depress the CNS, relieve pain, induce feelings of euphoria.
Stimulants
Activate motivational centers; reduce activity in inhibitory centers of the CNS.
Hallucinogens
Distort perceptions and evoke sensory images in the absence of sensory input.
Consciousness
Our awareness of the outside world and of ourselves, including our own mental processes, thought, feelings, and perceptions. EEGD show alpha and beta waves.
