STATES OF CONSCIOUSNESSREVISION
CHAPTER 2
Cribb, Gridley, McKersie, Rice & Anin (2004)
consciousness {p96} as a psychological construct informed by the work of
René Descartes {p97} and William James {p100}
‘…the awareness of objects and events in the external world and of our own existence and mental
experiences at any given moment.’ Your consciousness is changing
and shifting depending on your attention.
• Dualism• The mind & the body are 2 different
things.• Mind: non-physical spiritual entity (soul)• Body: physical, fleshy structure (matter)• Mind and body come interact through
the pineal gland.
‘…consciousness is constantly changing.’ It is like a stream, a
continual flow of ‘thoughts, feelings,
perceptions, images, sensations and so on.’
Total AwarenessState of focused attention
Divided attention
Daydreaming state
Meditative state
Hypnotic state
Sleep state
Anaesthetised
State of unconsciousness (coma)
Complete lack of awareness.
States (levels) of consciousness
Normal Waking Consciousness2/3 of day in this state
Altered state of Consciousness
concepts of normal waking consciousness {p105}
and altered states of consciousness {p115},
including daydreaming, meditative and alcohol-induced, in terms of levels of awareness, content limitations, controlled and automatic processes, perceptual and cognitive distortions, emotional
awareness, self-control and time orientation
‘…refers to the states of consciousness associated
with being awake and aware of our thoughts,
memories, feelings and the sensations we are
experiencing from the outside world.’
‘Attention in a concentration of mental
activity that involved focusing on specific
stimuli while ignoring other stimuli.’
Often used as a measure of
awareness to distinguish between
different states
Automatic Processes
Controlled Processes
Stroop effect
‘…used to describe any state of consciousness that is distinctly different from normal waking
consciousness…’
Distortions of perception & cognition
The Stroop Effect
The Stroop Effect
The Stroop Effect Tendency is to automatically read the word
Reading is an automatic process
Takes much longer to state the colour of the ink as we have to prevent automatic
processing and impose controlled processing
Conclusion – automatic processing takes precedence over controlled processing
Distortions of Perception & Cognition (thought)
• Sensations can become vivid, dulled or not experienced at all
• Can sometimes hallucinate – perceive what does not exist
• Sometimes perception so distorted people cal have out of body experiences, or
lose sense of their identity
• People often experience disorganised thought – illogical, lacking in sequence
• Also difficulty problem solving and remembering
Changes in self control• Our ability to maintain self control
may be raised or lowered during an ASC
• Lowered inhibitions displayed by people affected by alcohol.
• May gain greater self control under hypnosis e.g. conquering addictions.
Changes in emotional awareness• Emotions are experienced differently during an ASC. • Emotions may be heightened or dulled, - happier or sadder. • Being in an ASC may cause emotions to be expressed inappropriately.
Disturbed sense of timeIn an ASC time is experienced at a different speed than in NWC. Eg
sleeping, daydreaming
Cribb, Gridley, McKersie, Rice & Anin (2004)
Frequency
High = faster & more
brain waves
Low = slower & less
brain waves
methods used to study the level of alertness in normal waking consciousness and the stages of
sleep:– measurement of physiological responses including
electroencephalograph (EEG) {p133}, electrooculargraph (EOG) {p135}, heart rate, body
temperature and galvanic skin response (GSR) {p124}
– the use of sleep laboratories, video monitoring and self reports
AmplitudeHigh amplitude; bigger waves with bigger peaks and troughsLow amplitude; smaller peaks and troughs.
Electroencephalograpg (EEG)
‘detects, amplifies and records general patterns of
electrical activity of the brain.’
Galvanic skin response‘…a physiological response that indicates the change in the resistance of the skin to
an electrical current.’
high emotional arousal,
increase in sweating =
increase in electrical
conductivity (decrease in
electrical resistance)
Measures eye movements or eye positions
through activity in eye muscles
Brain wave patternsBeta:
when the brain’s activity is at it’s highest. High
frequency and low amplitude.
Delta:
slowest brain waves, low frequency,
high amplitude. Deepest state of
sleep.
Theta: medium frequency some high
amplitude mixed with small
amplitude. Early stages of sleep.
Alpha: high frequency, low amplitude
(slightly larger than beta). Relaxed or meditative state.
PRACTICE EXAM QUESTIONS
Renaé Descartes’ theory of consciousness as a psychological construct relies on the concept that
a) The mind and body are separate entitiesb) Interactions between brain neurons influence our
consciousnessc) Consciousness is an everchanging stream of ideas
and occurs only in the braind) Consciousness is produced by the soul and is located
in organs such as the liver and heart
QUESTION 1
VCAA Psychology Exam 1, (q1), 2011
Hilary has been knitting for twenty years. She is able to knit quickly and accurately while she watches television. Her granddaughter, who is just learning how to knit, makes many mistakes if she tries to knit and watch television at the same time.
This is becausea) Hilary is in an altered state of consciousness when
she is knittingb) Knitting is a controlled process for Hilary and an
automatic process for her granddaughterc) Hilary is able to divide her attention while her
granddaughter is unable to divide her attentiond) Hilary is able to use selective attention to know while
her granddaughter needs to use divided attention
QUESTION 2
VCAA Psychology Exam 1, (q2), 2011
Paulette meditates to reduce her stress levels.Evidence that Paulette is in a meditative state could include
a) Reduced heart rate, alpha waves, lowered temperatureb) Increased heart rate, increased breathing rate, beta
wavesc) Reduced heart rate, beta waves, low galvanic skin
responsed) Alpha and beta waves, reduced breathing rate,
increased muscle activity
QUESTION 3
VCAA Psychology Exam 1, (q3), 2011
Psychological measures such as those in Question 3 are useful for measuring an individual’s state of consciousness. However, it should not be assumed that a person is an altered state of consciousness on the bias of these measures alone because
a) These measures re not as accurate as self-reportb) An increase or decrease in heart rate is possible as a
result of meditationc) Psychological measures are subjective measures of a
person’s state of consciousnessd) Changes in psychological responses may be due to a
range of reasons other than a person’s state of consciousness
QUESTION 4
VCAA Psychology Exam 1, (q4), 2011
Petra was completing her psychology examination.
At the beginning of the examination, various thoughts were active in her mind such as how to fill in the multiple-choice answers, whether she should attempt the short answer questions first, and that the room was a little cold.Petra’s state of consciousness is best described as
a) Dualismb) Selective attentionc) Normal waking consciousnessd) An altered state of consciousness
QUESTION 5
VCAA Psychology Exam 1, (q5), 2011
Petra was completing her psychology examination.
Petra’s thoughts then began to drift onto other things while completing the examination, such as what she will wear at her school formal, what everyone else will be wearing, whether the boy she likes will notice her.The term that most accurately explains Petra’s experience at this time is
a) Daydreaming b) Meditative state c) Content limitationsd) Automatic processing
