Consciousness is a central fact of human existence, because without it, all other aspects of our life (perception, thought, emotion, etc.) are meaningless.
Characteristics of Consciousness
- Involves short-term memory.
- Is independent of sensory inputs (e.g., fantasizing).
- Requires focused attention.
- Has the ability to process alternative interpretations of complex or ambiguous data.
- Disappears and reappears during sleep (deep sleep to dreaming), at least in a changed or disjointed way.
Methods to Investigate Consciousness
- Observing and measuring the actions of an experimental subject, collecting reports of internal experience (e.g., heart rate, breathing, overall brain electrical activity).
- Investigating patients with brain injuries.
