States of Consciousness
Define consciousness as a psychological construct and explore the continuum of awareness. Students will compare normal waking consciousness with altered states of consciousness.
TL;DR:This topic explores the nature of consciousness as a psychological construct, ranging from total awareness to complete lack of awareness. Students learn to distinguish between normal waking consciousness (NWC) and altered states of consciousness (ASC), whether naturally occurring like sleep or induced like alcohol consumption. They also examine the physiological measurements used to track these states, such as EEG, EMG, and EOG.
About This Topic
This topic explores the nature of consciousness as a psychological construct, ranging from total awareness to complete lack of awareness. Students learn to distinguish between normal waking consciousness (NWC) and altered states of consciousness (ASC), whether naturally occurring like sleep or induced like alcohol consumption. They also examine the physiological measurements used to track these states, such as EEG, EMG, and EOG.
In the Australian context, it is important to acknowledge different cultural perspectives on consciousness, such as the 'Dreaming' for First Nations peoples, which represents a sophisticated understanding of reality and spiritual awareness beyond NWC. This topic is highly suited to data analysis and station rotations where students interpret 'brain wave' readouts. Students grasp the differences between states of consciousness faster through collaborative analysis of physiological data and role-playing the effects of different substances.
Key Questions
- How do we measure states of consciousness using physiological and psychological indicators?
- What distinguishes normal waking consciousness from altered states?
- How do stimulants and depressants affect brain wave patterns?
Watch Out for These Misconceptions
Common MisconceptionConsciousness is an 'all or nothing' state.
What to Teach Instead
Students often think you are either awake or asleep. Using a 'continuum' activity where they place different activities (meditating, driving, dreaming) along a line of awareness helps them understand consciousness as a sliding scale.
Common MisconceptionEEG measures what a person is thinking.
What to Teach Instead
Students sometimes think brain waves reveal thoughts. Through data analysis stations, they learn that EEG only measures the electrical activity (frequency and amplitude) of the brain, not the specific content of the mind.
Active Learning Ideas
See all activities→Stations Rotation
The 'Polygraph' Lab
Set up stations with printed readouts of EEG, EMG, and EOG data. Students must work in groups to 'diagnose' the state of consciousness (e.g., deep sleep, alert, or intoxicated) based on the frequency and amplitude of the waves.
Think-Pair-Share
NWC vs. ASC
Pairs are given a list of characteristics (e.g., time orientation, content limitations, perceptual distortions). They must categorise how each one changes when moving from a classroom setting to a state of daydreaming or being under the influence of a stimulant.
Simulation Game
The BAC Comparison
Students use data to compare the cognitive effects of sleep deprivation with specific Blood Alcohol Concentrations (BAC). They must create a visual chart showing at what point 17 hours of wakefulness equals a 0.05 BAC in terms of reaction time.

The Purpose and Function of Sleep
Examine the biological rhythms of sleep, including circadian and ultradian rhythms, and the stages of NREM and REM sleep. Students will evaluate evolutionary and restorative theories of sleep.

Sleep Deprivation and Sleep Disorders
Analyse the effects of partial sleep deprivation on affective, behavioural, and cognitive functioning. Students will also explore interventions for circadian rhythm sleep disorders.
