Unit One Part Two Vocab Flashcards
The scientific study of the links between biological (genetic, neural, hormonal and psychological processes
Biological Psychology
A Circadian state characterized by partial or total suspension of consciousness, voluntary muscle stimulation. Other characteristics include unique sleep-related electoencephalogram and brain-imaging patterns. These characteristics help distingish normal sleep from a loss of consciousness due to brain injury, disease or drugs
Sleep
A condition of awareness of one’s surroundings, generally coupled with an ability to communicate with others or to signal understanding of what is being communicated by others. It is characterized by low-amplitude, irregular, fast wave electrical activity in the raw electroencephalogram
Wakefulness
Our biological clock: regular bodily rhythms that occur on a 24 hour cycle
Circadian Rhythm
An example of this is Jet Lag: ________ results from traveling through several time zones in a short time span
Disruptions to Circadian Rhythm
________ occur as one enters initial Stage 1 sleep. They are bizarre experiences, such as jerking or feeling of falling or floating weightless, while transitioning to sleep
Hypnagogic Sensations
This is a very light sleep, our brain is still fairly active and responsive to sensations around us
NREM 1 or Stage 1
Alpha waves
NREM 1 or Stage 1
Light sleep, transitional sleep
NREM 2 or Stage 2
Theta Waves
NREM 2 or Stage 2
A deep sleep, heaviest sleep, slow waves, get shorter throughout the night
NREM 3 or Stage 3
Delta Waves
NREM 3
This stage contains night terrors, sleep walking, and sleep talking
NREM 3
During the ____________ stages of every cycle, we get deeper and deeper into our feeling of sleep. It is harder to wake us, it takes longer to get stimulation to wake us up. We are transitioning, lowering, and slowing down (Heart rate, blood pressure, temp)
NREM stages 1-3
Paradoxical sleep, dreams typically occur during ________. We are sound asleep but internally we are very awake- our brains are active, our internal systems are active too.
REM sleep
Gets longer throughout the night
REM sleep
Beta Waves
REM Sleep
Nightmare/bad dreams occur in this stage
REM Sleep
A sequence of images, emotions, and thoughts passing through a sleeping person’s mind
Dreaming
The increased occurence of REM sleep following REM sleep deprivation
REM Rebound
Dreams are the brain’s attempt to synthesize random neural activity. REM sleep triggers neural acivity that evokes random visual memories, which our sleeping brain weaves into stories
Activation Synthesis Dream Theory
Dreams help us sort out the day’s events and consolidate our memories
Consolidation Dream Theory
Sleep helps us organize, restore and rebuild our memories of the day’s experience
Memory Consolidation Theory of Sleep
Based on an evolutionary approach, sleep preserves energy and protects us
Energy Conservation Theory of Sleep
Many disorders interrupt healthy sleep, and their effects on waking behavior and health vary. ________ can affect physical and cognitive performance during wakefulness. Treating sleep disorders and following regular sleep schedules can improve waking performance and overall well-being
Sleep Disruption Effects
A persistant disturbance of typical sleep patterns (including amount, quality, and timing of sleep) or the chronic occurence of abnormal events or behavior during sleep
Sleep disorders
Recurring problems in falling or staying asleep
Causes: Stress, genetics, lifestyles and Caffine
Symtoms: Tired, waking up too early, feeling depressed or cranky
Insomnia
A sleep disorder characterized by uncontrollable sleep attacks. The sufferer may lapse directly into REM sleep, often at inopportune times
Narcolepsy
This sleep disorder in which you physically act out vivid, often unpleasent dreams with vocal sounds and sudden, often violent arms and leg movements during REM sleep
REM Sleep Behavior Disorder
A sleep disorder charachterized by temporary cessations of breathing during sleep and repeated momentary awakenings
Sleep Apnea
HINT: SNORING
Also know as sleep walking, when people get up and walk around while asleep
Somnambulism
The sense of sight, in which the eye is the receptor and the stimulus is radiant energy in the visible spectrum
Vision
