Mind/Body problem Dualism Materialism
Controlled Processes Requires full awareness (talking on a phone)
Automatic Processes Little awareness (driving while singing)

Consciousness Altered States
Produces awareness that differs from normal consciousness (meditation, hypnosis, drugs, sleep)
Unconscious Selfish needs Immoral urges Unacceptable desires
The ProofExperiments demonstrate existence of levels
Priming = quick responseMere-exposure effect = not consciously
remember stimuli (Déjà vu)

peace and tranquility Physiological effects

Correlates Reduced anxiety levels Reduced insomnia Improved self-esteem
Sleep Characteristics
Patterns follow circadian rhythm (biological clock) Avg. 4-6, 90-minute cycles of NREM/REM Need for sleep (Infants = 20 hrs.) (Adults = 6hrs.) 40-50% of sleep takes place in Stage 2
Stages of Sleep Stage 1: slow pulse, relaxed muscles (drifting) Stage 2: sleep spindles, heart rate decreases Stage 3: sleep for 30-45 minutes Stage 4: deepest sleep REM Sleep: the dream stage
The Hypnic jerk – common in sleep deprived people, during early stage – muscles misinterpret signals from RAS (relax)
Dreaming Lucid dreaming – directing your own dreams Freud
Dreams fulfill desires Activation Synthesis theory
Random neural firings Info Processing theory
