Flashcards in Consciousness Deck (20):
1

Conscious

- To be awake

2

Fully Conscious

- Mentally alert and in a clear state

3

Altered State of Consciousness

- Evident due to changes in mental activity
-> Shifts of attention
-> distorted perceptions
-> shifts in memories

4

Normal Waking Conscious

- Different to ASC:
-> Level of awareness
-> Quality of experiences
-> Intensity of experiences

5

ASC: Sleep

-> Naturally recurring state
-> Characterised by reduced / absent consciousness
-> Relatively suspended sensory activity
-> Inactivity of nearly all voluntary muscles

6

ASC: Daydreaming

-> Visionary fantasy
-> Experienced whilst awake

7

ASC: Meditation

-> People train their minds a mode of consciousness to realise some benefit

-> Personal practice

8

ASC: Hypnosis

-> Induction of a state of consciousness
-> Person loses power of voluntary action
-> Highly responsive to suggestion or depiction

Can be used to recover suppressed memories

9

Waking Consciousness

-> Consciousness experienced in everyday life
-> Alert and aware of surroundings

-> Stroop effect: Suggests we are not always in control of what we pay attention to.

10

Waking Consciousness: Pain

Unpleasant feeling associated with damage / irritation to body

-> Treatments are medication, cognitive / behavioural techniques

11

Waking Consciousness: Selective Attention

-> Focus on something & exclude everything else around us
-> Directs attention purposefully

-> High levels and low levels of awareness

Gives priority to some stimuli over others

12

Waking Consciousness: Divided Attention

-> Attention is divided b/w numerous tasks
-> Stimuli demands the same / less attention as each other

13

Waking Consciousness: Habituation

-> Predictable & unchanging stimuli fail to command attention
-> Repetitive stimuli is ignored e.g. fridge humming
-> All of these occur frequently and person learns to block noise

14

Waking Consciousness: Dishabituation

-> Change in events that causes us to become aware of them

-> Change in repetitive stimuli

15

Amplitude

- Size of peaks and troughs from a baseline of no activity

16

Frequency

# of brain waves per second

17

Measuring States of Consciousness

Brainwaves: EEG
-> Records amplitude and frequency

-> Frequency decreases as consciousness decreases


Heart Rate
-> Greater heart rate, greater state of arousal
-> Done through taking pulse
-> Exercise, fear / drugs can stimulate heart rate
-> Meditation = decrease

Body Temperature
-> Drugs can increase body temp.
-> Measured through skin of fingers

Galvanic Skin Response
-> Change in electrical conductivity of skin
-> Perspiration inc. electrical conductivity
-> Measured by attaching electrodes to hairless parts of body

18

Distortions of Perception

Stimuli and experiences lead to things being expected
-> these inc. level of attention, level of awareness, subsequent response

19

Perceptual Expectancy

A readiness to respond in a certain way because previous experiences

20

Multi- Lyer Illusion

2 lines of equal length, different shaped ends
-> illusion occurs because eyes look in wrong place
-> Eyes are drawn past the lines w/ feather tails to make line look longer
