Consciousness (Awareness)
A person’s awareness of everything that is going on around them at any given moment, which is used to organize behavior
-Not all forms of awareness are the same
Circadian Rhythm “24 Hours”
The cycle of physiological and biological processes that fluctuate on a roughly 24-hour timetable (16 hours awake and 8 hours asleep)
-Sleep and wakefulness
- Metabolism
-Core Body Temperature
-Cortisol levels
-Melatonin levels
-Other hormones (growth hormone, thyroid hormone, etc.)
The Wake/Sleep Cycle
Sleep has a biological rhythm, cycle every 90-110 minutes, dive distinct stages
- The pattern occurs three to five times per night
Insomnia
The ability to get to sleep, stay asleep, or get a good quality of sleep (psychological and physiological)
-Most people with insomnia spend more than 20 to 30 minutes falling asleep or getting back to sleep at night
Sleep Apnea “Stop Breathing”
Chronic medical condition where the affected person repeatedly stops breathing during sleep
-These episodes last 10 seconds or more and cause oxygen levels in the blood to drop or awakenings from sleep
Narcolepsy “Sleep Attack”
Sleep disorder in which a person falls immediately into REM sleep during the day without warning
- Narcolepsy is a genetic disorder, usually a trigger is an intense emotion
Night Terrors “Nightmare on Steroids”
Relatively rare disorder in which the person experiences extreme fear and screams or runs around during deep sleep without waking fully (combined with sleepwalking)
-Typically affects children
Dreams
A dream can include any of the images, thoughts, and emotions that are experienced during sleep
-We all dream, even if we cannot recall our dreams
-The dreams of REM sleep are so vivid we may confuse them with reality
REM or Sleep Paralysis “Waking Nightmare”
The presence or persistence of features of rapid eye movement (REM) asleep during the transition into or out of sleep
- Your body is paralyzed so tat you do not act out your dreams. When these features occur during wakefulness, you will have an experience of sleep paralysis
REM Rebound
Lengthening and increasing frequency and depth of rapid eye movement (REM) sleep which occurs after periods of sleep deprivation
-When people are unable to obtain an adequate amount of REM sleep, the pressure to obtain REM sleep builds up
Activation-Synthesis Theory
Dreams come from a purely physiological/biological view. There is nothing to interpret, dream are meaningless.
Information-Processing Theory
Dreams are the brain’s attempts to make sense of what we encounter during the day. Dreams are one way we actively process and analyze information rather than just respond to stimuli.
Hypnosis
An induced altered state of consciousness that heightens a person’s suggestibility, openness to responding to suggestion, without losing their sense of self.
Manifest Content
Dreams that are obvious and open.
Latent Content
Hidden; what the dream’s content actually represents
