- 2) Preconscious: taking ideas not in your direct awareness & giving them priority (e.g. aware that someone is watching you)
- 3) Unconscious: unavailable to awareness in most circumstances (e.g. body lang, cocktail party, reading, etc.)
- 4) Non-conscious: e.g. blinking and breathing
-
Aspect of waking consciousness
- selective attention:
- divided attention: being two places (mentally at once; multitasking
- inattentional blindness: refers to inability to see an object in our midst

EEG: Electroencephalogram
recording of brain activity
-
Rouge Test

-
REM (rapid eye movement)
darting of the eyes underneath the closed eyelids during sleep
-
REM sleep
- stage of sleep during which the brain is most active and during which vivid dreaming most often occurs
- most REM and high level of brain activity
-
Non-REM (NREM)
states 1 through 4 of the sleep cycles during which eye movement do not occur and dreaming is less frequent and vivid
-
Lucid dreaming
experience of becoming aware that one is dreaming
-
Circadian Rhythm
- cyclical changes that occur on a roughly 24 hour basis in many biological processes
- body temp, urine production, metabolis, (stress) hormone
-
Insomnia

-
Evolutionary theory
we evolved to sleep so that we would conserve energy when we were least effiicient
-
Waves / Sleep ordering
- beta waves – awake
- alpha waves – calm wakefulness
- theta waves – stage 1
- sleep spindles and K complexes – stage 2
- delta waves – stage 3 and 4
- REM
- sleep
-
More Ordering
- awake and non attentive - closed eyes, awake, meditating alpha waves
- awake and attentive - low amplitude, fast, irregular, beta waves
- sleep stage 1&2 - brain enters a high-amp, slow, regular waves = theta waves (e.g. daydreaming)
- sleep stages 3&4 - deepest sleep, brain activity slows down, large amp, delta waves
- stage 5 - sleep cycle starts moving backwards towards stage 1, beta waves, low amp, fast, regular
-
Hypnosis
set of techniques that provides people with suggestions for alterations in their perceptions, thoughts, feelings, and behaviours
