consciousness Flashcards
consciousness
awareness of thoughts, feelings, perceptions and surroundings at any moment
types of consciousness
continuous
changing
personal
selective
NWC
normal waking consciousness
when we are awake and aware of our thoughts, memories, feelings and sensation’s
everyday life without the need of aid
ASC
distinctly changing different in the quality and pattern of thoughts, feelings
achieved by use of an aid
induced
physiological response detectors
DARE Detect Amplify Record Electrical activity
EEG- Encephalo
DARE of the brain in the form of brain waves
EMG- Electromyograph
DARE of the skeletal muscles
indicating change in muscle activity and tension
EOG- Electrooculograph
DARE of the muscles that control eye movement to measure REM and NREM
speed and accuracy on cognitive tasks
used as a measure of an individuals ability to use controlled processing over auto
C.T try to be as objective as possible to allow consistent and standardised testing to occur
sleep diaries
self reported method
recording of time slept and awake
waking participants up at various stages of sleep to describe experience
video monitoring
infrared light is used so that the person is not woken
used to measure sleep behaviours
naturally occuring
sleep
daydreaming
coma
induced
alcohol induced
meditation
anaesthetic
consciousness characteristics
levels of awareness content limitations controlled and automatic processes perceptual and cognitive distortions emotional awareness self control time orientation
levels of awareness: NWC
awake and aware of internal and external events
good sense of time, place, reality
levels of awareness: ASC
increased or decreased
usually lowered during ASC but can be increased when person experiences heightened awareness
content limitations: NWC
constrained and controlled
can process information effectively
content limitations: ASC
more or less
less constrained or controlled with reduced ability to process information but fewer limitations on content
controlled and automatic processes: NWC
able to perform within normal limits
attention is focused and can be divided between tasks
controlled and automatic processes: ASC
less ability to perform controlled and automatic processes
less control over attention, cannot divide between tasks
perceptual and cognitive distortions: ASC
perception may be altered
memory process disruption/distortion
thought processes are disorganised and less logical
perceptual and cognitive distortions: NWC
perceptions are realistic and normal
effective controlled of memory (storage and retrieval)
thought processes are organised and logical
emotional awareness: NWC
greater awareness of emotions and control of emotional awareness
emotional awareness: ASC
less control of emotions
self control: NWC
more control over actions and movements
self control: ASC
less controlled over actions/movements
time orientation: NWC
clear sense of time
time orientation: ASC
distorted sense of time may appear to speed up/ slow down
level of awareness
awareness of internal and external events
content limitation
amount of control you have to limit what you attend to
controlled and automatic processes
ability to perform 2 or more tasks at once depending on complexity
perceptual and cognitive distortions
awareness and efficiency of perceptions and cognitions
emotional awareness
experience of emotions
self control
monitoring behaviours
time orientation
ability to perceive speed at which time passes
continuum of awareness
ASC:
total awareness
lack of awareness
NWC:
focussed attention
ordinary wakefulness
divided attention
stimulants: substances
speed up body’s physiological and mental processes
(coffee, nicotine), heart rate, pupils>
stimulants/brainwaves: substances
increased physiological arousal
increase beta waves
decreased alpha, theta, delta waves
depressants
substances that slow down body’s physiological and mental processes
stimulants and brainwaves: depressants
decrease physiological arousal
decrease beta waves
increase alpha, delta, theta waves
sleep deprivation
results in a negative mood state
irritability, short tempered, impatient
alcohol/mood
emotions and mood may be exaggerated or intensified
little control over mood and may fluctuate
overly emotional , inappropriate
