Conscious Mind
This part of the mind can take on a variety of roles, but it must focus sequentially on one thing and then another.
Conscious Mind
A state in which there is a shift in the quality or pattern of mental activity as compared to waking consciousness
Altered state of consciousness
"Internal body clock" that regulates the (approximately) 24-hour cycle of biological processes; responsible for the sleep-wake cycle
Circadian Rhythm
Happens shortly after a person falls asleep, in the Non Rapid Eye Movement (NREM) & wakes up screaming and have no idea why and it is not a nightmare. Most common in children (boys) between ages 2-8
Night Terrors
Any dream in which one is aware that one is dreaming, it seems realistic and vivid, high beta waves
Lucid Dreaming
When your brain is doing multiple things at once
Multitasking
Mind-wandering, is defined as spontaneous, subjective experiences during wakefulness, characterized by thoughts and imagined situations that are unrelated to the current task or environment
Daydreaming
In this stage of sleep people experience hypnagogic images, hypnic jerk and produce alpha waves
Stage 1
What is the scientific term for sleep walking?
Somnambulism
This is not a dream but a state of consciousness in which a person is especially susceptible to suggestion.
Hypnosis
The state in which thoughts, feelings, and sensations are clear and organized, and the person feels alert
Waking Consciousness
Processing that is conscious, in which you are aware of your thought process and are focusing your full attention at the task at hand (effortful processing).
Explicit Processing
You dream in this stage and the body des not move
REM
The person suddenly slips into REM sleep during the day.
Narcolepsy
The theory that dreams are disguised fulfillments of repressed wishes, offering a glimpse into the unconscious mind, where desires and conflicts are often expressed symbolically
Freud -Wish fulfillment theory
According to Freud, memories & stored knowledge is kept at what level of consciousness
Preconscious level
Processing that happens without conscious awareness, in which you can perform an action before you even become aware of it (automatic processing).
Implicit Processing
In this stage of sleep delta waves are occurring & growth hormones reach their peak, muscles and tissues are repaired, boosts immune function, and builds up energy for the next day.
Stage 3 & 4
Triggered by a strong emotion, most commonly laughter. A sudden loss of muscle tone (cataplexy) that leads to weakness and loss of muscle control.
Cataplexy
This theory states that dreams helps us to sort out the day's events
Information processing theory
Consciousness has 3 main functions: 1) it allows us to create a mental model of the world that we can manipulate, 2) provides us with a mental “meeting place" for our senses to create our perceptions and ?
Restricts our attention.
Freud felt that this part of the mind was not directly accessible to awareness; a dump box for urges, feelings and ideas that are tied to anxiety, conflict and pain.
Unconscious mind
Increased amounts of REM sleep after being deprived of REM sleep on earlier nights
REM rebound
The person stops breathing for nearly half a minute or more and may wake up momentarily, gasps for air, then falls back asleep.
Sleep Apnea
A neurobiological theory that explains that dreams are the brain's attempt to make sense of random brain activity that happens during sleep
Activation Synthesis theory
