1

Subjective data

Data collected through personal observations, interpretations, emotions and judgement

2

Objective data

3

State of consciousness

An individual's level of awareness of internal and external stimuli at any given moment

4

Attention

A voluntary or involuntary tendency to focus on a particular stimulus and ignore another stimulus

5

Normal waking consciousness (NWC)

A state of consciousness characterised by clear and organised alertness to internal and external stimuli

6

Altered state of consciousness (ASC)

A state of consciousness that is characteristically different from NWC in terms of awareness, sensation and perception

7

Different types of ASC

Naturally occurring ASC
Induced ASC

8

EEG

Detects, amplifies and records the brain's electrical activity - brainwaves

9

EOG

Detects, amplifies and records the electrical activity of muscles that control eye movement

10

EMG

11

Self report

Involves an individual keeping a record of their own subjective experiences
