- 1CONSCIOUSNESSAwareness we have of our external surroundings and internal processes at any given moment.
- 2CONSCIOUSNESS CAN BE:Personal: Subjective understanding of the external world - varies for individuals
Selective: Consciously choose to shift our attention
Continuous: Never empty - always aware of something
Changing: We shift attention to new stimuli when bought into our awareness - 3STATE OF CONSCIOUSNESSThe level of awareness we have of our mental processes and external surroundings
Varies at different times - 4NORMAL WAKING CONSCIOUSNESSRefers to the states of consciousness associated with being awake and aware of thoughts, feelings, memories and sensations we are experiencing from the outside world
- 5ATTENTIONMental activity which involves focusing on specific stimuli whilst ignoring others
Can be focused internally or externally - 6SELECTIVE ATTENTIONChoosing to focus on a certain stimuli whilst ignoring others.
Fail to notice other information while using selective attention - 7DIVIDED ATTENTIONAbility to distribute our attention and focus on more than one activity at the same time
Depends on how much conscious effort is required to do a task. - 8CONTENT LIMITATIONS IN NORMAL WAKING CONSCIOUSNESSContent held in Normal Waking Consciousness is more restricted/limited because we can selectively control what we pay attention to and block unwanted information.
Information is organised/logical - 9CONTROLLED PROCESSESUse selective attention
Tasks are difficult/complex
Requires high conscious awareness and mental effort
Parallel - can only preform one at a time
Used when tasks are unfamiliar - 10AUTOMATIC PROCESSESEasier/less complex
Little conscious awareness and mental effort
Series - can preform more than one task at a time. - 11ALTERED STATE OF CONSCIOUSNESS (ASC)Refers to any state of consciousness distinctly different (in terms of level of awareness, experience and quality/intensity of sensations, perseptions, thoughts, feelings and memories) from NWC
- 12DISTORTIONS OF PERCEPTION IN ASCMakes senses more receptive to external stimuli, eg. colours brighter, sounds louder
OR
Dulls senses to point were sensations aren't felt at all
People may lose their sense of identity - 13DISTORTIONS OF COGNITION IN ASCThought processes are disorganised
Thinking is illogical/lacking in sequence
Trouble remembering events that occur whilst in ASC
Recalling info from long term memory is difficult - 14TIME ORIENTATION IN ASCEstimation of time is frequently distorted
Time seems to pass at a different speed than normal - 15CHANGES IN EMOTIONAL AWARENESS IN ASCIndividuals may have uncharacteristic responses
Inappropriate emotions
Unpredictable emotional responses - 16DAYDREAMINGASC where awareness shifts from external stimuli to internal processes
Occurs naturally
Occurs when stationary/doing routine or boring activities
May be consciousness responding to unchanging external world - 17HOW IS DAY DREAMING DIFFERENT TO NIGHT DREAMS?Daydreams have minimal eye movement
high levels of alpha brain waves
content is less organised/meaningful - 18MEDITATIVE STATEUse of a technique to deliberately alter normal waking consciousness in order to induce an ASC.
characterised by a deep state of relaxation.
involves altering the normal flow of conscious thoughts. - 19PSYCHOACTIVE DRUGChemicals that change conscious awareness, perceptions or moods eg. Alcohol
- 20DEPRESSANTProduces mild euphoria by depressing brain centres responsible for inhibition, judgement and self control
eg. Alcohol - 21PSYCHOLOGICAL CONSTRUCTConstructed to describe specific psychological activities or patterns
Cannot be directly measured but believed to exist
Can only be inferred through behaviour or physiological measurements - 22ELECTROENCEPHALOGRAPH (EEG)Detects, Amplifies, Records electrical activity of the brain associated with different mental processes/behavioural responses
- 23BETA WAVESNWC, Alert, Awake
High frequency
Low amplitude - 24ALPHA WAVESNWC, relaxed, wakeful, meditative
High frequency
Low amplitude - 25THETA WAVESASC, early stages of sleep
Medium frequency
High + Low amplitude - 26DELTA WAVESAssociated with deepest stages of sleep
Lowest Frequency
Highest amplitude - 27GALVANIC SKIN RESPONSEMeasures electrical conductivity of skin
more sweat = higher electrical conductivity = higher emotional arousal - 28SLEEPRegularly occurring ASC which occurs spontaneously and characterised by a loss of consciousness
- 29POLYSOMNOGRAPHYIntensive study of a sleeping person involving simultaneous monitoring and recording of various physiological responses during the night
- 30SLEEP LABORATORIESWhere sleep research takes place
- 31ELECTROMYOGRAPH (EMG)Used to detect, record and Amplify electrical activity of muscles
- 32ELECTROOCULARGRAPH (EOG)Used to detect, amplify and record electrical activity of the muscles that control eye movement
- 33BODY TEMPERATURE DURING SLEEPDrops as we go into deeper stages and rises as we come back into lighter sleep.
